У меня 1920x1080 светодиодный дисплей. Если я установлю более низкое разрешение, это немного размыто. У меня последние версии драйверов, что делать?
LCD monitors will only ever look nice and crisp when set to their native resolution. In your case, 1920x1080.
If things are too small to read, you're best bet is to keep the 1920x1080 resolution and adjust the screen "DPI" setting in your OS. You haven't specified what OS you're running, but assuming it's Windows:
If you select a non-native resolution, the driver has to calculate every pixel value from the original image where it corresponds to a fraction of a pixel. The interpolation error of up-sampling results in the blurry impression you have noticed.
The error can be reduced if you select a resolution with the same aspect ratio (width / hight) as your native resolution. Example: If the native resolution is twice the resolution of the original, it can simply be calculated by repeating every pixel horizontally and vertically.
As said before, on an lcd screen you can only choose multiples of your native resolution to avoid the blurry effect. So for your 1920*1080 screen you should lower your resolution to 960*540 which is much too low for you I guess.
