I am using an old Acer S211HLbd monitor from 2011, it only has VGA and DVI inputs, I bought a new video card and of course it only has HDMI and Display Port outputs, I have display port to DVI and HDMI to DVI adapters that I tried with the new 5700XT but couldn't get a signal either way in either of 2 PCs I tried. I was thinking the video card was DOA but am wondering if the monitor being that old could cause it. I have used the HDMI and Display Port adapters on my current card and both work on the monitor, but I wanted to ask to see if it could be the monitor instead of the card.
