I recently upgraded to a entirely new tower and hooked up my set up to the tower. both monitors will then say signal lost but I can still hear whatever is on the monitors and someone screen sharing is still able to interact on them.

I tried to buy a new cable for the second monitor but all it did was allow me to use both monitors for a few minutes before shutting off the display.

The computer also revs up the fans when the monitors loose signal.

Any advice would be great.

The issue with the fans show there is something wrong with the computer, likely the video card.

From the post title when using one of those monitors using the same connections work fine correct?

Yeah if I use the monitors independently testing both ports the work. but as soon as I plug in both the monitor shuts off. I was able to get it where they would run for a few minutes when both plugged in but then the same issue happened again.
