Looking for an inexpensive graphics card that has an HDMI out and will fit the following computer.
Will just be supporting a single 43” TV as the screen on a 20’ HDMI run. Not doing any gaming just runs my security cameras.

I'd check Fleabay or do a Google search or place WTB in Classified.
Shouldn't be all that hard to find.
USB versions are in the $30 ~ $40 range.

I'd just probably buy the cheapest major name I could find on Amazon or Newegg. They seem to start around $40. I don't think that use is all that demanding so it should be easy to solve cheaply.

this is about the cheapest. Be sure to use the blue S-S USB connector on your computer. There are cheaper ones, but not from brands that I know, so I'm hesitant to suggest them. .

I notice you have ample PCIe ports in the PC. You could go with something like this. BUt then again, I hate to suggest one with a fan. I hate adding yet another fan which adds noise and dust.

there are cheaper, but this is a brand that I know and mostly trust.

whatever you buy, make sure it has drivers for your OS, which I would guess is windows 10?

Like the idea of the fan since this thing stays on 24/7. Noise and dust are not really an issue where it is located.

What you are looking for is an SFF card; small form factor.

Got the one linked above today installed super easy and downloaded the NVidia Control Panel.
Loaded the drivers up and looks good.

Only problem now is the TV I am using is only 720P and 32”
Have a 43” 1080P in the bedroom and basement. Maybe the basement needs replacing with 4K then that will head to the bedroom and the bedroom one head to the shop!
