Hi,

I have a Windows 7 desktop that is connected to 3 display TV's via VGA. They are set to clone display and only 2 of them are connected - The 3rd one just says 'no input'. The settings on all 3 TV's are the same and they are the same make and model.

It can't be the graphics card as all 3 TV's are usually displaying. It is only today that one of them isn't working.

Any ideas?

Thanks

The TV's are left on 24/7 displaying from the PC and all 3 were working until I remote controlled the PC last week. There were 2 working and now there are none working.

When you say remote controlled the pc, do you mean you used some remote desktop software like teamviewer to access the pc from another location ?

Remote controlled via MSTSC.

I remote controlled the PC as it is locked away in a secure room and the TV's are rigged up in the office downstairs. However, to avoid remote controlling again, this morning I went over and plugged in a 4th monitor into the 4-way splitter (the 4th one being a Dell PC monitor) and it displayed on this one fine. So it must be a problem with the main monitors being TV's. When I look at the settings on the TV settings they are all set to VGA.

Have you checked in device manager, monitors section to make sure all the monitors are being picked up.

That's a point, no they aren't showing. The only monitor that is showing is the Dell. I'll try plugging the Dell monitor into one of the adaptors for the TV's and see what happens. Will post the outcome after.

I have figured the reason why 2 of the screens went dead was because I was remote controlling the PC over MSTSC. When I started using the PC directly, the TV screens came back to life! The 3rd TV I found had a bent pin in the VGA cable causing disruption to the connection - so somebody would have been medling with the equipment when they shouldn't!

Thanks for the suggestions.
