OSSC has no EDID on it so there's a need for an external solution for that, PowerStrip can be used to make custom resolutions with specific refresh rates, and I think it can force refresh rates too. I'm sure some other tools exist for refresh rates management too.

It would be nice if I could select different refresh rates on the desktop like I would if the computer was hooked up to a regular monitor.

And what, does the OSSC have problems with this? That is, you can’t just set, say, 1920x 1080@100hz on the desktop? (Through ForceWare 2.0+ settings or in display properties)? I did not expect this from such a product. As far as I know, even ordinary active adapters allow this, but perhaps they have the same "EDID".

Please keep us posted if you can get @100hz on your desktop using OSSC. Perhaps this will save other users from mistakes who have not yet chosen an adapter, but are going to do it and are considering OSSC as one of the options for such an application.

Also try the following setting:

REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\0000\DEFAULT]
"DDC"="0"

Where "0000" - is the actual ID of the adapter being used (may be different in your case).

With powerstrip I am able to get different refresh rates selected and displayed with the OSSC. The problem now is that there are fuzzy, flickering spots all over the picture and it is cropped in an offset position. I'm not sure how much this can be fixed since my monitor has limited scaling options. So far I've tried 70, 72, and 85hz all with similar results. I tried messing with the advanced timing sampling options but nothing I changed helped much other than adjusting the position on screen.
