Custom Resolution Utility (CRU)

[abeardedpirate]

Hello there. I am a dumbass and it took me a stupidly long amount of time to get CRU to work for me to enable Dolby Home Theater the first time I tried this.

I used EDWriter-beta 2 to grab my TV (LG C1) EDID then moved the cable over to my Onkyo HT-S3800 and grabbed it's EDID, merged them together, then I used CRU 1.5.3 to load the bin file and viola my Dolby Home Theater works when using version 3.14.67.0 of the Dolby Access app.

However on my previous setup, same video card (2080 TI) same TV (LG C1) I was able to also have VRR enabled. Before doing this merge I was able to have 1080p 119hz VRR enabled but after doing the merge VRR is no longer possible to enable via Display -> Advanced Display or by going to nVidia Control Panel as the option is not there.

I have no idea what I did before that allowed me to enable VRR but I would very much like to be able to turn that back on if possible.

The only thing I could find for CRU edits was to change the Range Limits but those are already set at:
V Rate 24 - 120 Hz
H Rate 30 - 255 kHz
Max Pixel Clock 1190 MHz

I can't find anything else about editing edid with CRU to tell Windows my TV has VRR. Is there a HEX Value I should edit with the EDWriter that would tell Windows to enable VRR?

The only other thought I have is that I need to reassemble my old PC and just steal its EDID info with EDWriter and move it over but it'd be so much better if I understood how to do this going forward when I eventually upgrade to something better than the 2080 TI.

Hopefully I posted this in the right forum.

HDMI VRR is in the HDMI 2 data block.
