Hey folks,
I just built a new htpc and when I play a movie, the display goes blank and comes back too bright (about 20 clicks on the brightness control on the tv).This happens with 2 different programs (latest build xmbc and J.River Media Center 17 with MadVR).
The hardware:
Asus p8z77-m with i5 3570k/hd4000, 8gb ddr3-1600 running Windows 7 64-bit, all latest drivers from the respective vendors (not from Asus as they don't update very fast).
hdmi goes to a Denon AVR-4306, hdmi out to LG 50PK250.
I went through all the settings to make sure its all set to RGB 16-235, I've reset the TV to defaults and redid its initial wizard and I ran Windows calibration (didn't change anything except gamma slightly down, certainly not the 20 notches described above, not even close
).
The desktop looks good but when I start a movie, mkv 1080p x.264, the display goes blank and after a short second comes back too bright, it looks really washed out. I need to drop brightness about 20 notches on the TV controls to compensate. Then when I look at the Intel COntrol Panel, I notice Quantization range is back to default. When I change that back to limited and leave the window open, I will get a dialog box stating 'please wait while settings are being applied'. When that's done, its back to default again.
I'm not sure if that setting is responsible for the washed image as I don't see a change when I manually set it back, but obviously I don't want it to do that. I've disabled 'movie detection' in the control panel too as I figured that was detecting playback and forcing settings, but that didn't make a difference.
Also note that the movie doesn't have to play full screen. In MC17 I can play it in a window and I actually see the entire display is too bright, not just the movie window.
I'm not sure what to try next though, I just want video to play back 'as is', I never had this problem with my old htpc (ASRock ION 3D, Atom 525D with Nvidia stuff).
Any help would be appreciated,
Thanks!
