[SOLVED] 75Hz option not available

[Synk]

In my monitors manual it says that it supports 1280 x 1024 resolution at 75Hz via HDMI(PC), I use an HDMI connection, have tried all available resolutions including 1280 x 1024 in windows but i still get only up to 60 Hz in the menu. I tried setting up a custom resolution through AMD Radeon software but it tells me "Setting not compatible with display"

Monitor is LG 22MT44D and GPU is R7 260X on Windows 7.

Did you press the TV/PC button on the remote? According to the manual 75Hz is possible in PC mode.

Thanks for the reply,
It already was on pc mode, I tried changing it to TV and then back to PC again but no results.

You've done what the manual suggests to do so if it's not working then probably lg have incorrect information described in the manual for your monitor.

What happens when you force 75Hz under Windows' Advanced Settings-->List all Modes button? You can set modes that don't appear in the menu there, because they are all the ones the adapter supports and not just the monitor.

Catalyst/Crimson may also under "Display" let you tinker with display timings if you set the monitor to manual instead of EDID

Its definitely not incorrect because i just tried it on another PC and the 75Hz option appears there.

There are no 75Hz options under "List All modes" menu. Does this mean my GPU does not support it?

How exactly do i set the monitor to manual? I dont find the option in Radeon software.

Try custom resolution utility

You may need to turn off GPU scaling. This prevents refresh rates above what is available at max resolution.

This worked, thank you very much!
