I've owned the NAD T748v2 since boxing day and I've been having problems with short video drops. I run my PC via HDMI from a Radeon 7970 3gb to the NAD T748v2, with video output to my TV.
The problem I'm experiencing is that the video signal appears to be regularly lost - the screen will go black for a second, then resumes normally, while audio through HDMI continues to play. This problem seems to happen at random times - occasionally in the middle of a netflix program, sometimes while just browsing the web, once or twice just on my desktop. It never seems to happen while playing a game. Sometimes it is isolated with only one video drop and sometimes it happens back-to-back repeatedly for several seconds. The only thing that I've found reliably reproduced this problem is when I begin playback on netflix (screen blacks out for a second as soon as video is finished loading).
This problem is not present when running HDMI directly to my TV. It also does not occur when running my Intel i5 IGP via hdmi to my receiver. I have reproduced it on two seperate TVs.
What I've tried:
1) Reinstalling display drivers (14.12 omega)
2) Switching my 7970 bios to stock backup
3) Changing refresh rate to 60, 59, 50
4) Changing pixel formats
5) Probably more failed fix attempts that I'm forgetting
I'm at wit's end. Any insight is appreciated, let me know if I can provide more info.
