The native resolution of my laptop's 15.6" display is 3840 x 2160. Unfortunately, I found that the graphics on many applications didn't scale appropriately for this resolution, and were pixelated/blurry despite checking or unchecking the option in the Compatibility pane for "Display display scaling on high DPI settings".
I changed the resolution of the display to 1920 x 1080, and from what I understand, if the scaling is correctly applied, the display output should be equivalent to 1080p resolution on a 1080p display of the same screen size, as 4 pixels on my display would correspond to a single pixel on that display. However, items on my screen appear to be very small, as you can see here:
I'm not sure if this is the intended size of icons, taskbar and windows, but when I set the scaling to 125% (medium), some applications begin to have pixelated/blurry images again:
Is the 100% scaling the default scaling for 1080p (4 pixels to 1 pixel), and why does the blurriness/pixelation sometimes occur when I increase the scaling? Is there any way of fixing it? This is an example of the blurring of some programs at 125% scaling, which is non-apparent at 100%:
100% is too small. there should be an option in 'Control Panel\Appearance and Personalization\Display' which says "Let me choose one scaling level for all my displays". make sure it's unchecked. and what is your graphic card? – None – 2014-11-21T08:27:41.903
I tried unchecking that option, but some programs (especially the text), while appearing larger (scaled to a larger %), still appear blurry to a minor extent. My graphics card is an NVIDIA GeForce GTX 860M 2GB. – amy – 2014-11-21T09:55:59.247
you can't get your desired result by changing scaling settings, that's for other purposes. the only options for you will be playing with graphic card settings and screen resolutions. your monitor's resolution is something between FULL HD and Standard UHD (4K) so unfortunately that kind of problems are prevalent because it is lower than the 4K industry standard of 4096 x 2160. – None – 2014-11-21T14:23:47.513
