Some feedback on my testing, after Win11 upgrade yesterday, using a LG C8 Oled + 1080Ti latest driver, lastest .80 JR28.
- Perma HDR is not an option, as it uses gamma 2.2 for HDR>SDR and it looks washed out on an oled. Pluge pattern confirms it, it brightens out of black way too quickly (bar 17 is perfectly seen in daylight, which should not be)
- Resulting from the above, SDR movies look washed out
- HDR movies look fine but lack punch (compared to madvr doing the hdr switch)
When configured without OS HDR enabled, madvr switching :
- SDR is fine, as is desktop
- HDR is fine, but if you hover the jriver menu on top, it will switch to SDR mapping and revert back once menu goes away (TV remaining in HDR mode)
>> This is an OS or madvr issue, same behaviour observed with MPC-BE, but just good to now that even with HDR off, windows will do its thing. Perhaps jriver could be flagged as HDR capable so that this doesn't happen ? Looks like the OS thinks jriver is an SDR app with encapsulated HDR capability ?
- After having played an HDR movie, any SDR movie will look completely dark. Hovering the menu gives normal picture again, until it's hidden, goes dark again
>> Could be an OS or driver or madvr issue, but interesting thing is, if I shutdown jriver completely and restart, SDR plays fine again
Imho, OS HDR will be usable the day we get to choose the gamma target for SDR mapping, before that, no thanks, it turns an oled into a LCD.
It's a huge step on the right direction, but we're not there yet.
