today I tried to connect my personal computer with my 65ru8002 but without any success.
There is only a blue screen on the TV. First I decided, that the Computer is faulty, but when I tried with another display, it works fine.
I tried to change the HDMI port, I tried with different cable - but the result is the same - HDMI port is in the unrecognized state, and there is no picture.
I believe this is related to the last firmware (i checked, and the FW version is 1356)
The same PC works perfectly with my 48h6400, also with normal 22" monitor.
Also, I found another Samsung tv owners having the same problem, reported in other forums.
I tried to check for the new FW version, but unfortunately, there is no FW version.
Please help with this problem.
