OK, now that I found out that Quest headset PTC's can be rolled back (Ryan, please get rid of your outdated first link and just use the second one, thanks) I broke down and enrolled into the v51 PTC on my Quest Pro today. This was a fairly large update that included firmware and Pro controller updates. I also needed to enroll in the oculus desktop beta PTC.
All went well and everything seems to be working well with standalone and wireless PCVR using Air Link. Starting up Air Link is still a little cranky but I've found that if I just go to quick settings/settings/system/Link and wait for air link quality items to refresh and go Green, then on the same panel ask it to startup link, then launch, it seems to work 99% of the time.
The new Local Dimming feature (shows up at the bottom of ODT and is enabled by default) seems to work fine and really improves blacks and contrast in darkish apps. Colors seem to pop out even more now as well. This works with all PCVR apps (eg. from Rift, Steam, or VivePort stores). Some apps seem to benefit more than others and some dark screens with white (or light colored) things can have a little Bloom halo around them.
I found the best way to minimize Bloom was to adjust the Quest home quick menu Brightness slider down to about 85% and to then add a tiny amount of contrast in the setting (personalize?) contrast slider (hunt around for it and you'll find it. I think that the contrast slider was introduced back in v49, so most should have it by now, lol!
The Local dimming feature is only available with the Quest Pro since the Q2 screens do not have this capability. I'm not sure if the upcoming Q3 will have capable screens or not.
Nice to see the Quest Pro finally getting some love. I'm not saying that Local Dimming makes the Quest Pro's lcd's look as good as oled's, but I will say that my good old Vive Pro1 (with AMOLED screens, etsy lens mod, and Index controllers) may start collecting a bit of dust, lol!
For those that want to know what Local Dimming does and are too lazy to Google, here's a nice brief explanation I saw on another forum today;
OLED screens can individually dim the brightness of each pixel for better blacks/dark colors.
IPS screens, which most VR headsets use, can’t. So iirc what local dimming does is it dims the backlight zones instead, which are spread throughout the screen.
