In 18.3.4 i was able to choose 1400x1050 resolution but after the last two update there is no such option.I tried to create custom resolution but when i choose it in game it gives me out of range error. My gpu is r9 380 btw
vsr and gpu scaling are disabled.My monitor is benq xl2411 it's native resolution is 1920x1080.The thing is when i revert the driver to 18.3.4 i can still play with that resolution so it is definitely a driver problem.
Same problem different game, the resolution 1400x1050 has also vanished from windows display properties and the driver will not allow it as a custom resolution. trying to force it in cfgs in some older games results in those games running at 640x480
I'm unsure whether this would count as an error in the new driver, or a correction with the new driver. Seeing as you mention your display is 16:9, it wouldn't be able to display a 4:3 resolution properly anyway. The fact that it was an option previously could be the error, and it has now been fixed so that it no longer displays an incorrect resolution option?
Given that 1400x1050 is the only 4x3 resolution to have disappeared this is unlikely (640x480, 800x600 and 1024x768 for example are all still selectable). besides which 16.9 displays have always supported 4x3 resolutions either by stretching or with black borders.
My best guess is MS broke the Presentation Mode (Windows Key + P) 1803, like completely, this will be controled by a app called DisplaySwitch.exe located in your Win/system32 Folder. You will also find dpiscaling Digimonutl, and all things monitor related there. The TrustedInstaller is probably the owner , or a random default user, sometimes in win10 caller unknownUser123.xxx.xxx..xx is generated ....
Anyways head down there and take a look, ill bet not even a folder icon is associated to it. Reassign that and anything else you can think of to Full Permissions Trusted Applications and System, and assign ownership to SYSTEM.
If you run into trouble with that or not to puter savy let me know, i can walk you through a easy way.
Ok cracked it. Going into custom resolutions set timing standard to "CVT- Reduced Blanking" instead of "manual" and it allowed the creation of 1400x1050 as a custom resolution I can now use
