I have Dell computer. My Samsung smart tv UE55H6500 is connected with it through hdmi cable. Sometimes I use my tv as a display instead of my Dell monitor. Now I can't anymore and I don't know why.
I have another tv, Samsung UE48H6400. When I connect it with my computer (same computer, same HDMI cable, same ports... etc.), it works perfectly.
It seems the problem is in 55" tv. How can I be sure? What can I do?
Is there any software update for my TVs? Current software version on my 55" tv is 2781.
As soon as I put HDMI cable that connects computer with my TV into my computer, picture from my monitor disappears. Monitor is connected through VGA port. As soon as I disconnect the cable between TV and computer, picture in monitor shows up.
Could You, please, help me?
Yes, I've rebooted them both.
No, it doesn't. Even with monitor unplugged, I don't get picture from computer to TV.
I don't get TV to show computer's picture any possible way. 😞
Is there any way of checking if anything is wrong with my TV (HDMI input ports) beside taking it to service? Any diagnostic software, any online test...?
I managed to get it to work, but only using HDMI port "on the side" of TV numbered HDMI1 and HDMI2, that I used for Samsung soundbar connection. Since it works on HDMI1 and HDMI2, and it doesn't work on HDMI3 and HDMI4 ports, does that means these 3 and 4 ports are definitely broken? Can that be repaired? Any chance problem is in software not hardware? Can You please suggest a solution?
Thank You very much for Your help!
I unplugged all HDMI cables from my TV and then I unplugged TV's power cord for half an hour. No luck.
Then I did a factory reset, nothing changed.
Is there anything else I can do?
