Howdy!

I recently got a GeForce GT 1030 to replace my old GeForce 7300 LE. When I try to boot up with the new card, the only thing my TV shows is "Not Supported", more or less referring to the HDMI input.

When I was using the GeForce 7300 LE, it was connected to the TV via VGA, at a resolution of 1920x1080 at 60Hz.

Now that I plugged in this new card, nothing shows up at all. My guess is that the computer is automatically changing the resolution to fit with the new card, which supports 4k, though I'm not 100% sure.

I tried reinstalling my old card to bump down the resolution, then reinstalled the new card, but to no avail. I've also tried other HDMI cables and slots, but none of that is working. Other HDMI devices seem to work with the TV. I don't really know what else to try.

Any suggestions?
