I have a monitor (SyncMaster P2250) which I previously used in Win10.
I could achieve up to 75 Hz at 1920x1080 using NVIDIA Control Panel.
In Win98, I couldn't find this setting in Driver 40.72.
Decided to check using Regedit and found this:
In HKLM\Enum\Monitor I found 'MonitorRanges' string which looked loke this: "30-81,56-60,+,+". I tried to change it to "30-82,56-70,+,+" but "70 Hz" didn't appear in Adapter tab after reboot.
I also found HKCC\Display\Settings -- it had 'RefreshRate' set to '-1' -- I figured out it corresponds to currently-selected 'Optimal' refresh rate. Changint it to '70' didn't make monitpr run at 70 Hz.
Do I need to create custom monitor driver?
Can anyone give me an insight?
