HDMI Disconnected - but it's not and picture is showing (SAMSUNG)


Novice Member
Has anybody experienced anything like this before?
I have a HTPC GTX970 outputting to a Samsung JU6400 (65in).

At random times, sometimes while watching full screen video, other times while reading on Chrome I get an HDMI disconnected popup. But the video is still displaying behind the popup.
The only way to remove it is to power cycle the TV.

If I change sources, it won't allow me to change back to HDMI as there is 'no signal'.
Current Samsung OS version 1402.

dr no

Try a different cable?
