Title: 4k Playback
Post by: maid on November 07, 2018, 09:00:58 pm

Tried to play a 4k rip yesterday and was getting freeze ups and pixelation also the dts hdma kept reverting to DTS

Perhaps my settings are not quite right or possibly the rip

Currently re ripping for testing

I am using ROHQ

any help would be appreciated

1080 is surely powerful enough to process 4k ... few questions:

1. are other 4k rips playing ok?
2. while playing video ... press Ctr+J to bring up madVR OSD ... print screen that and post it (might help troubleshooting)

If you are running MC24.0.54 or above, Ctrl+J works without doing anything special. Earlier versions didn't.

Your GPU is pretty powerful and will have no problems playing 4K Material, especially as your LF6300 is only a 1080p TV.  I don't know if you have manually modified your madVR settings, but MC also added some new HQ Profiles so you can just use those, and with a 1080 I'd say you could use Tools--> Options--> Video--> Load madVR quality preset--> High Quality (but not if you have mad any custom changes to madVR these will be reset).

I have not modified madvr but just tried another 4k and it seems ok. Nevertheless I might try the suggested setting high quality

Tried madvr high quality. This seems to affect the sound so I have turned this off

Playing 4k material on a 1080 TV could be what's causing you issues. I believe downconverting is more resource intensive than upconverting, or just outputting 4k. There was one setting I changed in madvr to fix this on my PC. I can't remember off the top of my head but can probably post it later. If your GPU is having trouble downconverting, windows task manager should show it approaching/spiking to 100 percent.

I have reverted back to madvr default and all is ok.
I just wondered why it would alter the sound
Also I bitstream through onkyo
I should also have said i was not playing 4k at the time
