Question Custom resolution is not supported by your display...

[HuNTeR-]

I want to create a custom resolution 2048x1536 on my 4k display through Nvidia panel,and don't let me to have this resolution.Why?I tried every posibilities : Progressive,Interlaced,DMT,CVT,Manual ,Automatic etc....
I want this resolution,because i play some old games in 4:3 image format and i don't want to be streched...
I remember when i have Radeon graphic,red team let me without problem to set any custom resolution.....why Nvidia don't let me?I have latest driver instsalled.

You might not be able to set a 4:3 custom resolution of 1536 (vertical), which is a bit of an odd one which I'm not that surprised is not supported by the display.

But have you tried any other 4:3 resolutions?

1440 x 1080 would seem an obvious first thing to try and then work your way up ie. 1600 x 1200, 1856 x 1392 and 1920x1440 to see what the highest vertical resolution is supported, if any, in 4:3.
