Unsupported video format2021-04-19T12:42:50+01:00

I have tried to use a tv to replace my pc monitor. Initially it worked ok but the tv displayed a picture filling only half of the tv screen.
I altered the resolution of one of the devices, tv or pc. {Not sure which.} The result: tv screen displays following message “Unsupported
Video Format” on a black background whenever I try to repeat using it to display pc output. I have tried changing the pc resolution to no avail.
Is there any way I can reset the tv resolution. I’m locked out of it now, cannot find a way back in!

I have a Toshiba TV. Sometimes I have to reset the input to make the screen come to life. It may not be the TV. Still Ii am not going to buy a new PC because the TV does mot play well with my old Dell GX520.

The issue has to do with how HDMI works.

EDIT: Thee are many reports of users having difficulty with a VGA HDMI interface. Also, sometimes DVI HDMI mat not work very well.
A few:

Obviously, the quality of the adapter is a big  concern.

Thank you for reply,
I did use VGA to join the two up, as there were no HDMI ports on the PC. The PC is three years old, so cannot be returned to vendor. But I don’t think it is the PC that’s at fault, as it worked fine until I altered
the resolution. The problem is how to access the TV so I can revert it to original res, whatever that was,
and so get rid of black screen displaying the fault message.

Some TV sets don’t play well. If it we me, I would take the TV back to the vendor and tell them it does not work well with your PC.

I have two TV sets here for my PC. One is very well-behaved and the other always makes a fuss. The one that gives me trouble is a famous brand name!

Some TV sets do not do HDMI very well. Try VGA if you can.
