Mistmatched edid's

[Arvol]

In 5.04 I'm getting some really funky mismatching edid's.
My Nova processor, Windows machine and nVidia control panel all show 1920 x 1200, but when I try to go to advanced output in Arena, it's showing up as a 1536 x 960 ??
I've tried this even with a 1920 x 1080 and it's doing the same thing (the 1536 x 960 is changed to a smaller number but still within the same ballpark)
When I try a 720p it works fine, just nothing at or above 1080p.
Just upgraded to Windows 10, that was the only thing that's changed in my rig. Drivers are all up to date.

Any Idea's?
Thanks!

Check your windows scaling. Make sure it's at 100%

Bingo! That solved it. Scaling was set to 125%, oh windows....
Thank you for the help! You're a champ
