Trouble changing resolutions/edid around on an EDID Emulator Dongle

Hey all, weird project here. I’m currently working on a way to upgrade the screens in the ancient Oculus Development Kit 2. The premise of it is that I have one of those little dongle passthrough edid emulators that is emulating the edid of the dk2, and that signal is then being passed to a new screen.

Essentially, there are two parts to this.

1: Getting the Oculus DK2 EDID loaded onto the dongle. I have successfully done this [I used EDWriter to write the EDID]

2: Changing the resolution of this dongle to something higher. Here is where I’m having issues.

For testing purposes, I’m using an older version of the Oculus runtime (0.4), which allows me to treat the “DK2’s” screen as just another monitor screen and play around with resolutions, orientations, and refresh rates as such. Next, I imagined I just needed to throw a higher resolution into CRU and then let windows downsample it from there. This… doesn’t seem to work. Maybe I’m just formatting the resolution wrong, I’m not really sure, but it doesn’t even show up in windows. If I do a lower than native resolution, however, it works just fine.

Any ideas on why Im not able to put a higher than native resolution onto this EDID Emulator Dongle? Is there something in the DK2 edid file itself that’s preventing this? Can I modify the EDID itself? Thank you :slight_smile:

I’m not sure about your EDID questions (but I’m curious and hopes someone knows more about).

I just wanted to ask what kind of GPU you’re using, because both NVidia and AMD support custom resolutions in their current Windows software without the need for CRU. It might be worth checking to see if either of those support what you’re trying to do any better or differently than CRU.
