Dominic or anybody familar with madLevelsTweaker:
I have tried running the Tweaker app, but don't think it is doing anything. I went to the Doom9 forums to ask how to use this but I have no clue what is going on with my account on Doom9. I have not used my account in years, but I am able to log in, but can't see any forum threads when logged in. There is no way to contact an admin, as they have the contact us disabled for email. So I created a new account this morning to ask a question on the madVR thread. Turns out I am not allowed to post for 5 days from creating the account. Great.
Any help you could provide would be greatly appreciated. The post I tried to post is below:
I am trying to calibrate my TV using HCFR software. I have my laptop set to output FULL vs LIMITED, but I am being told from my scans that it appears I am not actually getting FULL from the laptop and to run the madLevelsTweaker application. So I have downloaded it, extracted it, and run it.
The initial time I ran it, it popped up on the laptop screen, I checked the box for "Force PC Levels" and hit "Apply". The red message popped up on the bottom of the screen stating a reboot was required, so I did.
Ran the same scans in HCFR and nothing changed.
I run the application again, and realized I didn't read the message at the top stating "Please move this window to the target monitor." So I did, but the "Force PC levels" box was already picked. So, I unchecked it and hit Apply. Then checked it and hit apply. Rebooted.
Ran the same scan in HCFR and nothing changed.
I am looking for help on how to make this work, and validate it worked. Which registry value gets changed in the registry path shown in the app? And what is the value originally, and what does it get changed to?
