After switching to 125% DPI the start menu titles become bigger (which is a nice thing) but also some weird blurring filter is applied to icons. Right away after you open start menu the icons are more sharp for 1 second then become blurry, is there any work around to change this behavior and made them more sharp? Btw. If I switch to start screen instead of menu, the titles are even more bigger (which looks really good <3) and they are less blurry than the menu ones (still a bit blurry though)
I notice from your specs that you have screen resolutions set at 1280x1024. This seems an odd size to me for modern LCD monitors and may be why you are seeing some blurry effects. I would choose the default resolution for the LCD screen (assuming it is something other than 1280 x 1024) and see if it is an improvement, it might be worth trying the 100% dpi setting again as well since that also is a recommended setting.
This is not a modern LCD, its from 2007, its native resolution is 1280x1024, image is sharp and crystal clear, it's good LG monitor. DPI of 100% isnt recommended because everything is too bloody small.
Thanks for clarifying the spec for your monitor.
I don't have much experience with the various dpi settings but there is another place where you can adjust the sizes. It is found by typing display in the search box and then selecting the Display control panel. Here you can set a custom scaling level.
I know what you are talking about, that is the DPI I am using because the default scaling method on windows 10 is broken, it makes fonts blurry in some places like Device Manager etc. it has been quiet loud about this for a while and they still haven't fixed that but to my surprise if you set 125% dpi on custom scaling level then all fonts are crystal clear and you don't have to install any 3rd party tools or do registry tweaks that need to apply at every reboot to fix them.
Interesting...
So you have crystal clear fonts but the icons themselves are just a bit fuzzy? Not sure I can help you any further as it sounds like you either have crisp icons and blurry text or crisp text and blurry icons. Did you experiment with Cleartype for the situation with blurry text?
I was also having problems with blurry text (icons, device manager as was mentioned above, etc) when I set the DPI to 125% on Windows 10, which I find to be the perfect scaling for me. The following program from XPExplorer.com fixed that problem. I am using it on both my desktop and laptop and it works perfectly (It reverts to using Windows 8.1 DPI scaling).
