Question Issues with HDMI on Radeon R7 265

[DavePenn]

Hi

I have an interesting issue with the Sapphire R7 265 and 3 displays.

I have 1 monitor connected DVI/DVI, a second connected DVI/HDMI and I want to use my TV as a 3rd display for movies etc. The connection is HDMI>Wall plate>HDMI 10m cable sub-floor>Wall plate>HDMI to the TV.

The issue that I am having is that it is not correctly displaying on the TV, the picture has bands, whites are showing as pink and there are random blue patches. Now, I can use the HDMI output from the onboard card (Intel HD 4600) and my monitors connected to the R7 without any display issues, however whenever I turn the TV on with this configuration the PC will freeze up.

I have the latest drivers and I have checked the card is inserted correctly...

Does anyone have any ideas?

Cheers
Jonathan

Have you tested this without that whole long HDMI run to the TV, just HDMI cable from the card to some display?

Ok, so further update.

The card is an R7, so it can only support 2 monitors via HDMI/DV-I, the rest have to be via display port.

I connected a 3rd monitor in place of the TV and the signal was fine (I had to deactivate a monitor to get it to display) but if I use the TV instead of the monitor, the signal is "fuzzy".

The issue seems to be compatibility with the TV and the card, which I haven't heard of before
