LG 27gl850-b stuck to 75Hz

Go to solution Solved by HairlessMonkeyBoy,

You are limited to 1440p @ 75Hz by the HDMI 1.4 port on your GTX 750. Newer HDMI revisions support higher resolutions and higher refresh rates.

Hi! So i have finished my PC build, well, almost. Still using my trusty old GTX 750 since where i live an RTX 3070 costs ~800 EUR. But i ran into a problem.  I cant set my refresh rate to 100Hz using an HDMI cable. HDMI+1440p= 100Hz. Thats what the manual is saying. And that`s not all. When i installed fresh windows for the first time the supported resolutions were very weird. I was able to select 1440p @ 60HZ, 1080p @ 120Hz and also for some reason 4k @ 30Hz if i recall correctly. 

I suspect some driver issues, but i have installed/uninstalled both display and monitor drivers for many times. Now im stuck to 1080p and 1440p @ 75 Hz. 120 Hz and 4k options are gone. 

 

Thanks in advance.
