Hi thanks it's Via a 4k splitter but still does the same when I don't have the splitter in line cable run about 15 mtrs, works perfect on the 1024x768 setting and the TV is a Samsung q9 model so should be able to cope with resolution,is the cable run more picky with the higher Res do you think

Hi just trying to change my output on my DVR to 4k onto 2 separate tvs but when I change from anything apart from 1024x768 the TV screen goes unreadable with just a lot of green lines on,one of the TVs definitely supports the 4k res,any one throw any light on what may be happening thanks
