Hello,

I have a windows 7 computer with 3 monitors setup. It was working fine, however something happened (not sure) and now the 3rd monitor gets no signal/and not detected. All 3 monitors worked together just the other day, and did so for months with no issue.

I have tried unplugging all monitors, turning computer off, plugging one monitor in at a time, but the problem continues. Also confirmed video source. Checked Windows updates/even restored back to previous date, plus updated video card drivers to the latest, but did not help.

If I unplug monitor 1 and 2, and just have 3 plugged in that monitor does work. Once I plug in either 1 or 2 or both in the 3rd goes out (shows no signal message).

Tried replacing the 3rd monitor with a different one using the same cable and it works with monitor 1 and 2.

I'm confused why the 3rd monitor has this problem.

Specs:
GeForce GTX Nvidia 1050 ti
Monitor 1 Samsung TV - plugged into HDMI
Monitor 2 Samsung TV - plugged into DP to HDMI
Monitor 3 Small 11" Eyoyo TV - plugged into DVI on video card to HDMI on TV

If I plug the 3rd monitor into a different device - it works.

Any thoughts or guidance would be appreciated.

Thanks!

Have you made sure you're on the latest BIOS update for your motherboard? Which drivers are you currently on? Might it be possible to pass on a link to the cables used?
