Escaping from computer reality now is really almost impossible. So the only way out is to adapt to it properly. For example, to adjust the computer monitor so that the eyes don’t get tired, and your head doesn’t hurt while completing tasks, playing free slots NZ, or watching Netflix for hours. Let’s understand the parameters of contrast and brightness, resolution and frame rate, display calibration.
Monitor Settings for Your Eye Comfort
Brightness and Contrast
Let’s start with the two main parameters known to us from the TV sets of the pre-computer era – brightness and contrast. They can be adjusted either programmatically, on the computer itself, or hardware-with the monitor options. Let’s talk about both methods.
For hardware adjustments we need buttons located on the monitor itself. The most common ones are the menu button and the buttons (or joystick) for navigating through the settings, besides the power button. So, we need to turn the monitor on, open the menu and then find the brightness and contrast sliders. It’s better to adjust the settings after the monitor is connected to your computer. This way you can assess the results of manipulation on a concrete example – for example, on the image of the desktop.
The software settings are made with the help of the pre-installed Windows tools. Open the “Settings” window (to find it, you need to enter this word in the “Start” drop-down menu). Then in the left pane select “System” and in the right part of the window click on the line “Display”. The brightness slider will be at the very top of the page. Adjust it to suit your needs. It’s also recommended to pay attention to the switch in the item “Night Light”: it makes the monitor switch to warmer and more comfortable for your eyes’ colors. It should be turned on when it’s dark.
Brightness and contrast should be low enough not to strain the eyes, but high enough for the user to see the picture on the monitor comfortably. To customize the settings, it is easiest to first set the brightness and contrast to maximum and then decrease them in sequence until the picture on the monitor is clear and “readable” enough.
Remember that different lighting conditions require different brightness settings. Say, in daylight in the middle of the day it is logical to set this parameter to 90-100%. Office spaces with cold light also require high monitor brightness settings. But at dusk or at night you can and even should lower it – with some models even 50% of maximum brightness will be enough in the dark: your eyes will only thank you.
Screen resolution is responsible for the details of the picture, namely the number of pixels displayed horizontally and vertically. It’s quite simple: for 90% of applications you will be satisfied with the resolution that coincides with the resolution of your monitor. For Full HD monitors it is 1920×1080, for 4K monitors it is 3840×2160 and so on. By default, Windows almost always sets the resolution that matches your monitor, but if it doesn’t, you can correct the situation in the same Settings window. Go to “System” and then “Display”. Look for “Display Resolution” and select the maximum setting.
Reducing the resolution can help if you are working with outdated applications or want to run a very old computer game that isn’t optimized for modern monitors with high resolution. In such rare cases, you can adjust the resolution setting in the familiar Settings window.
Screen Refresh Rate
Display refresh rate is responsible for a smooth change of image, namely the number of frames which are displayed on the screen in one second. Here the situation is similar to the resolution setting: it’s better to choose the parameter coinciding with the monitor’s refresh rate (measured in Hertz) on your computer. At the same time, the system will not allow you to choose too high a parameter. Go to the same “Settings” menu, select “System” and “Screen”, but this time look for “Advanced display settings” and click on it. At the bottom, there will be a drop-down menu where you can select the appropriate refresh rate.
Let’s also mention AMD’s FreeSync and NVIDIA’s G-Sync technologies. These technologies are very convenient and allow synchronizing the refresh rate of the monitor with the refresh rate of the picture, providing the smoothest animation on the screen. But in order to make these technologies work, you first need to enable them in a special program to manage your video card: in the case of NVIDIA video cards, it’s “NVIDIA Control Panel”. Secondly, you need a monitor that supports these technologies. Support for G-Sync and FreeSync are usually reported in the product specifications.
Software Display Calibration
Calibrating your monitor using software methods provides better contrast and color reproduction. It is recommended when you connect any new monitor to your computer. To call up the display calibration program, go to the “Settings” window, “System”, “Screen” subitem and click on the “Advanced Display Settings” line. Next, click on the blue highlighted text “Video Adapter Properties for Display”. This will open a new window, where you need to select “Color Management” in the top menu and click on the button with the same name. This brings us to another new window, where we are interested in the top panel item “Detail” and the button “Calibrate screen”.
Next, you will be asked to pass a series of tests for optimal adjustment of brightness, contrast and color rendering. Everything will be intuitive – just follow the on-screen text instructions. And don’t worry if you did something wrong: at the very end you will not only be offered to rollback your changes but you will also be able to compare the changed parameters with the ones set before. This is a convenient way to make additional adjustments to the monitor.
Basic Rules to Keep in Mind When Working at a Computer
Your Position at the Table
Proper computer posture is just as important to your health as your monitor settings. Sit up straight and make sure your eyes are at the top of the screen. The optimal distance from your face to the surface of the monitor for healthy eyes and comfortable work is 50-70 centimeters. Keep your back straight and lean against the backrest of your chair or chair – don’t sit on the edge! Your shoulders should be relaxed and your hands and forearms should be in a straight line.
What You Sit on
The best furniture for sitting at the computer is specialized chairs for office workers or gamers. The best ones boast not only soft backs and seats but also the ability to adjust the height. This, by the way, is an indispensable option in cases where one computer is used by several people. The armrests of such chairs shouldn’t prevent you from keeping your arms straight, and the backrest should support a comfortable posture. The ideal computer chair backrest should support the body in the lumbar region and slightly tilted backwards in the upper part. The upholstery material is non-discomfortable eco leather or polyurethane.
Correct Positioning of the Monitor
The monitor itself should be placed in front of you so that you don’t have to turn your neck during work, and the upper part of the screen is at eye level and 50-70 centimeters away. If the design of the monitor stand allows it, we recommend tilting the screen slightly upwards, so that you can always see the whole picture while sitting upright. At the same time, the tilt angle must not exceed the view angle of the matrix, so that you don’t get any visual artifacts or distorted colors.
In a room with a computer, you need to set the right lighting, to avoid glare on the display surface. Our main enemy is sunlight, so if there are windows near the workplace, they should be covered with thick curtains or drapes. The light from powerful lamps should never be directed directly at the screen – this will cause glare and make working at a computer a real torture. In order to have the light evenly diffused around the room you can use a floor lamp, lampshade or plafond. Desk lights with incandescent lamps also need to be directed away from the monitor or not use while working at a computer at all. The exception is LED lamps, the light which has a different spectrum and is not as harmful to the monitor.
