Way to test GPU that isn't connected to my desktop?

I have a graphics card that got knocked a few weeks ago and isn't working a week later - can't run HDMI through it after testing it (been using D-Sub since I started but occasionally used HDMI and now.it doesn't work). I'm unsure as to whether or not it's the graphics card or what connects it to the motherboard that's the issue, so if I can connect my graphics card to something else and see if it works there, then it'll easy to figure out the problem.

Is there a way/method I can test my possibly broken GPU?
