Lenovo laptop screen resolution. What kind of screen should a laptop have? Impressions of use
When choosing a laptop, you typically have to take many different factors into account. However, a laptop's display is one of the consistently most important criteria that should be among your main starting points.
The display has the greatest impact on the ergonomics of a mobile system. Yes, insufficient hardware performance will cost you time and frustration. However, an incorrectly selected display will lead to additional strain on the eyes, greater visual fatigue and decreased productivity. In the long term, it can even lead to more serious health problems, blurred vision, fatigue and headaches.
Key Features
To avoid all this, there are a few things to consider: display diagonal, resolution and coverage.
Today the market offers a huge variety of combinations in this regard, and in order to choose the most suitable one, you should also think about how exactly you plan to use the laptop. Of course, today a laptop computer has many different applications, but here we are talking about the main tasks: office work, games, watching movies, editing digital images and videos.
The first criterion here, of course, is the screen diagonal. The choice is large - from 10 to 17 inches, but this indicator alone is not enough to fully evaluate the ergonomics of the respective display and, accordingly, the visual experience that it can offer. Screen resolution must also be taken into account. The combination of these two measures is usually called "pixel density" and is defined as the number of colored dots (pixels) per square inch that make up the image on the screen.
The general principle here is that a smaller diagonal combined with a higher resolution results in a higher pixel density (ppi) value. Example: A 15-inch Full HD (1920 x 1080) display and a 10-inch HD (1366 x 768) display will offer almost the same pixel density (146 and 156 ppi, respectively).
Advantages and disadvantages
A little theory. Let's take printed publications as a basis. Most of them use a pixel density of around 170 ppi, which allows the content in them to be clearly visible to readers. This, of course, cannot be applied directly to their electronic alternatives, since we are talking about two fundamentally different methods of visualization - printing on paper and a luminous dot on a screen consisting of one or more diodes.
However, the pixel density of a standard printed publication is a good starting point. Taking this into account, we can easily conclude that the higher this indicator, the fewer individual pixels that form the image. This means an image composed of elements with finer details but also smaller relative sizes.
In other words, the combination of a small diagonal and high resolution results in a smaller image and, accordingly, less readable text on it. Windows offers options that allow you to increase the size of fonts, but at the cost of reduced image quality. Any modern monitor also allows you to change the resolution (and therefore the pixel density), but it is generally known that one of the most characteristic features of LCD / LED technology is that displays of this kind work better with the so-called “natural” (native) resolution, which according to the default is their maximum resolution.
Thus, when buying a laptop, choose the combination of diagonal and resolution that suits you best. For example, if you have vision problems and plan to use the laptop mainly for office tasks, then in this case you are unlikely to need a very high pixel density, which will only interfere with your ability to read small text, numbers and view graphics.
What else?
The display coating also plays a significant role here. We are talking about the difference between a matte (anti-glare) and a glossy screen, but in combination with the criteria that have already become a matter of choice, one of the two alternatives can make a significant difference.
Let's continue with the above example: a small display with too small details and a shiny finish can be hard on your eyes, especially if you look at it for 8-10 or more hours a day.
So, when choosing a laptop that will primarily be used as an office machine, it is better to think about a larger diagonal with a more modest resolution and a matte finish. In addition, lower pixel density has another undeniable advantage, which is a more gentle approach to battery charge.
At the same time, movie fans are unlikely to want to own a laptop whose display supports the maximum HD resolution (720p). Almost all modern films are distributed in widescreen format with high resolution Full HD (1920 x 1080 pixels and 16:9 aspect ratio). So if you plan to use the laptop mainly for watching movies, then it is better to choose a model with a widescreen panel and Full HD resolution (or higher).
A glossy finish will also be beneficial here, as it provides dense, rich colors.
Almost all of the same is true for users intending to use the laptop for video or digital image editing. High resolution is a must here; even a screen with a QHD+ (3200 x 1800) or 4K (3840 x 2160) resolution will not be superfluous and will provide a comfortable area for calm work on projects. The glossy finish in this case will also be an advantage - this way you will be sure that the display provides the most accurate and high-quality color reproduction.
Have a great day!
Lenovo B590 is a budget office laptop. The review is devoted to testing the performance of a model running on a Core i3 processor. Is this a balanced configuration or has Lenovo sacrificed too much?
It is generally accepted that laptops in the Lenovo B590 class are not powerful laptops that can easily handle demanding high-definition games, but are intended for creating emails, performing office tasks and making presentations. Such laptops should have a decent keyboard, be quiet and provide long-lasting battery life. The B590 is one such device. Its 15.6" display is large enough for easy viewing, yet mobile enough to be carried around occasionally. The laptop is equipped with an Intel Core i3-3110M, a 500 GB hard drive and 4 GB of RAM, which is enough for everyday tasks.
Frame
The design of Lenovo B590 is simple and discreet. It's completely black. Beveled edges make it more attractive and less ascetic. It is made entirely of plastic and has good build quality. Luckily, Lenovo doesn't use glossy surfaces that are prone to fingerprints. If you open the laptop, you can make sure that the interior is decorated in a similar way - there are the same matte, neat plastic surfaces.
B590 copes well with external influences. The surface around the keyboard doesn't flex, although the areas around the H and J keys are a bit givey, but acceptable. On the other hand, the display is not as stable. It gives under pressure when the laptop is closed, and its torsional resistance isn't class-leading. Its predecessors, the B570e/B570 and B560, differ only in minor details, but the basic design remains the same.
Connectivity
From the point of view of communication capabilities, the Lenovo B590 will not surprise you with anything. It is equipped with everything necessary for everyday use. There are a total of 4 USB ports scattered along both flanks. The majority of interfaces are located on the left, so you need to be prepared to deal with cables on your desktop on this side. Unfortunately, the laptop does not have a docking port at the bottom. In addition to Gigabit Ethernet from Realtek, the laptop is equipped with a Broadcom WLAN adapter that supports 802.11 b/g/N WLAN standards. There is also Bluetooth version 4.0. Users did not experience any problems with wireless connections. The signal level and transmission quality are stable regardless of distance. The reception quality is decent even at a distance of 10 m from the signal source behind two concrete walls.
Accessories
The included accessories are similar to those included with other laptops. In addition to the B590 itself, Lenovo provides a battery, power adapter, and the usual booklets. Installation DVDs are not included.
Service
The bottom of the laptop has a large hatch that hides the hardware inside the device. After removing two screws, the user has access to the hard drive, RAM, wireless LAN module and fan. Therefore, cleaning the air cooling system will not be difficult. In addition, the second RAM slot is free. The B590 comes with a one-year warranty. The manufacturer offers a large number of options for extending it for an additional fee.
The operating system with which the Lenovo B590 laptop was released was Windows 7 Professional 64-bit.
Input Devices
The Lenovo B590 keyboard is full-fledged, with a numeric pad on the right. The buttons, measuring 14 x 14 mm, are quite large. Their concave surface increases accuracy and speed of typing. The gap between the keys is about 4 mm. Therefore, input should be comfortable for users with large hands. The knocking isn't too loud, but it sounds cheap. Nevertheless, the key travel is comfortable and provides noticeable feedback. If the B590 is the first laptop from Lenovo, then at first there may be some problems with the small input and case change buttons, but after a while you can get used to it. The keyboard has a bit of give in the center. However, this only happens with the appropriate application of effort. Normal typing leaves the keyboard motionless or with only slight flex.
Fortunately, the 106mm diagonal touchpad (93mm wide x 57mm high) is quite large. Thanks to the slightly corrugated surface, fingers glide well over it. Additionally, the touchpad is tactilely and visually separated from the palm rest. There is a vertical scroll area on the right side of the touchpad. Multi-Touch technology also lets you navigate documents or web pages. It is especially convenient in Windows 8. If you prefer a mouse, the touchpad can be completely disabled. The two buttons below the touchpad have fairly short travel and make a loud clicking noise. Overall, the keyboard and touchpad leave a decent impression.
Lenovo B590: screen specifications
The laptop is equipped with a conventional TN display with a matte surface. Therefore, in bright light, it is not as reflective, making it suitable for outdoor and professional use. A resolution of 1366 x 768 pixels is standard for 15-inch office laptops. The screen does not show outstanding results. Its maximum brightness is 203 cd/m2. This is lower than the average for laptops, and the average (187 cd/m2) is even lower. Additionally, the brightness distribution of 82% could have been better. The display pleases with a decent black level (0.53 cd/m2). However, due to the low maximum brightness, the 381:1 contrast is mediocre.
The B590 doesn't cover reference color spaces, but that only matters to professional graphic designers and photographers. Outdoors, the Lenovo B590's matte screen has advantages, but it's not bright enough. 200 cd/m2 is not the brightest of its kind. However, the laptop can be used outdoors in the summer, as long as it is not exposed to direct sunlight.
In terms of viewing angles, the B590 has some shortcomings. When viewed from above, the display shows full brightness and colors are not distorted. If you turn the screen and look at it from the side, the brightness drops. When tilted, the image looks even worse.
Performance
The Intel Core i3 processor with integrated Intel HD graphics means that the Lenovo B590 laptop is not intended for demanding games and similar applications. The system is rather intended for surfing the Internet, creating office documents and presentations. Besides, 4 GB of RAM is quite small for resource-intensive tasks.
CPU
The 3110M clocks at 2.4GHz and has two cores. Thanks to hyperthreading technology, the chip can handle up to four threads simultaneously, but it lacks TurboBoost technology. Most Sandy Bridge family processors are rated at 35W, which is quite common in laptops 14 inches and above. The Lenovo B590 motherboard runs on the Mobile Intel HM77 Express chipset.
The 3110M's Cinebench R10 score of 4,209 is marginally slower than other laptops with the same processor, such as the HP ProBook 4540s, which scores 4,243. However, even laptops with Intel 2350M perform worse - they only have 3799 points. In multi-rendering, the 3110M reaches 9126 points. The PC Mark 7 test gives 2531 points, which is comparable to the Fujitsu LifeBook E782 (2578 points) or Acer Travel Mate P453 (2503 points). So, we can say that the Lenovo B590 performs as expected and its performance is excellent for a 15.6-inch office laptop.
Data store
The hard drive of the Lenovo B590 laptop is a 2.5-inch model (gross) with a capacity of 500 GB and a rotation speed of 5400 rpm. The average data transfer speed is 78.5 Mb/s, which is quite decent for such a device. The predecessors of the B590 performed much worse in this regard. The access time of 19.3 ms could be better, but is acceptable for this type of equipment.
Video card
In the Lenovo B590 laptop, the video card is integrated into the processor. The Intel HD Graphics 4000, while not delivering the best performance, is 60% faster than the HD 3000. The B590 scores 4,410 in 3DMark 06, placing it well in the middle of other similar laptops with Intel HD 4000 graphics. However, the B590 is slower than Lenovo IdeaPad N586 with 5277 points. 3D Mark 11 gives 555 points and indicates a slow laptop. Competitors like HP's 655 B6M65EA (361 points) or Samsung RV515-S03DE (555 points) are comparatively faster.
The B590 is definitely not designed for gaming. Its integrated graphics are simply not powerful enough. This is confirmed by The Elder Scrolls V: Skyrim test. Although the game runs on low settings, it becomes unplayable on higher settings. Games that do not require a lot of performance, such as FIFA, do not experience interruptions even at higher resolutions.
Noise level
In everyday use, the B590 is barely audible. When idle or under light load, the laptop makes almost no noise (30.8 dB). Only the hard drive sometimes rustles at a volume of 31.1 dB. Under load, the noise increases from 31 to 33.7 dB, but this does not pose a problem.
Temperature
In the case of the Lenovo B590, there is no need to talk about temperatures. Regardless of the laptop operating mode - idling or under load, the device never gets really warm. When idle, the maximum temperature is 27.2°C at the top and 29.1°C at the bottom. Even under high load the temperature does not rise much. The maximum is 36.2 °C at the top and 36.6 °C at the bottom. There is no need to worry about this level of heating, even if the laptop is lying on your lap outside in the summer.
Sound
The B590's speakers are adequate for an office laptop, but lack bass. As with previous models, they are located above the keyboard. Audio volume is fine. If you need more, you will have to use external speakers.
Power consumption
The Lenovo B590 has excellent energy saving system characteristics. The laptop is more efficient than its predecessors. When idle, with power-saving settings set to maximum (minimum display brightness, WLAN disabled, etc.), consumption is just 6.1 W, compared with 8.3 W for the B570e and 11 W for the B560. In other cases, energy consumption increases slightly. 8.7 W with maximum screen brightness and WLAN enabled is a decent result. The B570e already consumes an average of 11.5 W and a maximum of 11.7 W, while the B560 consumes 14.6 and 15 W respectively. The B590's highest power consumption is between 27.6 and 33.1 W. Thus, the model under consideration is superior to its predecessors in this indicator. We can confidently say that the B590 demonstrates excellent energy efficiency.
Battery life
The minimum load test showed 9 hours 27 minutes of operation without recharging. This value pretty much represents the limit of the laptop's capabilities, but in practice this rarely happens. At full load, operating time drops to 1 hour 33 minutes. A more informative WLAN test with a web page loading cycle at 40-second intervals and a display brightness of about 150 cd/m2 showed a decent 4 hours 44 minutes.
Lenovo B590: how to enter BIOS?
When switching to a new version of the OS, laptop owners often encounter problems. Lenovo B590 users were no exception. “How to enter BIOS?” - this question has visited many who have installed Windows 8. The simplest solution is to call up the settings menu by pressing Win+C and selecting the item to change PC settings. In the general category, click the restart button under the Advanced startup item. The computer will restart and give you access to boot options.
Verdict
The Lenovo B590 laptop is perfect for the office. Its performance is sufficient for everyday tasks. A matte display, a system with low noise levels and low temperatures are additional advantages when working in the office. The build quality of the plastic body is quite decent, but it can't compare with the aluminum models. Users expected a little more from the screen. Despite the matte surface, its brightness leaves much to be desired.
For those looking for a simple, quiet, low-heat office laptop, the Lenovo B590 is an excellent choice.
Advantages of the laptop:
Absolutely amazing laptop!
When choosing a laptop, the priority characteristics were as follows:
- Performance at an affordable price
- Cooling
- Design
Performance: high, games run at maximum settings, about which a lot has already been written, the hybrid hard drive from Seagate does its good job, the OS loads in seconds, programs launch instantly, virtual machines on VirtualBox run VERY fast.
Cooling: I didn’t see the point in taking a powerful configuration or ultrabook if it would be impossible to use this power due to overheating. There are no problems with cooling at all, even in heavy games there are no problems - no overheating of the video card, no heating of surfaces.
Design: I wanted to take an ultrabook, but without any loss in performance or cooling. This model is an excellent compromise. Essentially an ultrabook, only a little thicker. White, very nice, with a backlit keyboard and a metallic finish on the keyboard panel.
Other: The keyboard is CONVENIENT, no matter what they say, especially when touch typing. Dolby Home Theater produces powerful sound, the OneKey Recovery utility, a convenient Power Management application with a dust removal function and battery monitoring, and in general it all consists of nothing but advantages. It’s impossible to list everything.
Disadvantages of the laptop:
The viewing angles of the screen are really small. Not fatal.
- Screen resolution 1366x768. In the modern world this is really not much. It's fair to mention this.
- Windows 8. A completely nauseating OS - not because of the inconvenient menu with tiles, not because of anything for which it is usually criticized - you can get used to all this - but because of its impenetrable buggy and dampness.
Comment about the laptop:
Disadvantages that are often mentioned here:
- Matte screen: Excellent screen except for viewing angles. The colors are dimmer than on glossy screens, but it is a matte screen - on glossy they are brighter, but it is glossy. It's simple.
- Combined headphone and microphone jack: I think that for those who buy a laptop for 30k rubles, it’s not a problem to buy a headset for such a jack or an adapter.
- Cheap screen frame: normal frame. They say it hurts the eyes, but it doesn't. A completely ordinary frame.
- Battery is not removable: With the Power Management utility, which extends battery life, this is not a significant drawback. This is a small price to pay for the amazing design and ultra-texture.
- The lid is soiled: I don’t know, nothing gets dirty on it, I just ran my hands over it - no fingerprints, no stains. The keyboard buttons tend to collect dirt.
- The keyboard flexes: again, nothing flexes for me if I use it as a keyboard and not as a place to roll out dough.
- F buttons with Fn: the new firmware has a normal order, and few people use these buttons at all. It's only annoying when you accidentally press F4 instead of the volume control.
I hope this laptop will please me for a long time with its proper operation. Great model.
Regarding SSD optimization, I recommend reading the article: “12 myths about SSD optimization that will never die.” You can find it through search.
Note added May 31:
The laptop continues to please me with its performance. I wanted to add a little bit about the keyboard that everyone is complaining about. Revealed during operation.
They say it is soft and has a quiet, small stroke. I am comfortable! But the fact is that I periodically play online games and very often I have to press the buttons with great speed. When I play with friends, the sound of the keys being hammered so loudly in my ears that I can almost stop hearing the game. At the same time, my keyboard is not audible at all.
A properly configured monitor screen is the key to successful and productive work with a laptop. Optimal monitor setup begins with adjusting the basic components.
Setting the screen refresh rate
Right-click anywhere on the monitor. In the Properties section, open Settings → Advanced → Screen refresh rate. From the values that appear, select the maximum. Important: frequencies below 70 Hz are harmful to vision as they cause image flickering.
Adjusting laptop screen brightness
To adjust the brightness on your laptop, you need to find the function button with the image of the sun. The keys are responsible for this F5 and F6 in the top row of the keyboard. To set a comfortable brightness hold down the Fn button simultaneously with the F5 keys(to decrease brightness) or F6 (to increase brightness).
Brightness can also be adjusted via the control panel. Find the “Hardware and Sound” section, select “Power Options” and set the slider to the desired level.
How to adjust contrast
The Windows 7 operating system has a “wizard” with which you can adjust the brightness and contrast of the monitor. Control Panel → “Display” →. "Color Calibration" Next, follow the prompts.
How to change monitor resolution
Often, liquid crystal matrices are designed to work with a certain monitor resolution. The exact number is written in the “passport” for your laptop. It is possible to violate this value, but this will lead to image errors.
Show color gamut should not be higher than 1.8. Next, make sure that the square located on the left does not differ from the black background. To do this, change the brightness level. The “White Point” indicators must be reduced to 20, and the “All Cintrols” indicators must be set so that the squares acquire a gray tint.
You will see the test results immediately. The only downside to this program is the cost. However, there are several analogues, for example, the proven CLTest.
If home testing doesn't solve your problem, it's time to seek professional help.
Let us remind you that these are just basic monitor settings. There are a huge variety of programs for people who need special screen options.
