Hello,

My new TV (3 days old) is working properly in all aspects except when I connect it with an HDMI to my computer. what happens is that after connecting it for like 30 minutes, the screen goes black with colored horizontal lines at the top quarter, with normal sound playing. using my remote, I can go to Home page, or go to apps and watch something else, but the HDMI port tab that I have the PC connected in with always display the black screen with the lines. I usually unplug and replug, it works for another some time and then again I have the same problem. I had it with 2 HDMI ports.

The HDMI cable is fine, I use it on a PC monitor and it seems like its working well. the TV alone is fine. there seems to be a problem when connecting the PC with HDMI in particular.

Any suggestions? do you think its a hardware or some software issue (like framerate, refresh rate). what do you think?

TV is Sharp 43 inch Roku TV

Thank you!
