Does it take VGA? And do you have a spare PCIe slot?

You can slap in an old GPU to power it directly, with no latency or conversion issues. I know my old Nvidia 980 TI supports VGA directly, albeit with a passive dongle. As a bonus, this would save VRAM for your other displays.

Sadly it does not take VGA but I do have an old laptop with native VGA out so I could convert that to composite easier. VGA is already an analog format, right?

  Mmmm, yes, but for composite it’s not trivial like it’d be for S-Video. To quote some random Redditor:

  You need a device called frame buffer. VGA signal are sampled (ADC) and store in a memory. This memory is read by another circuity, at NTSC/PAL frame rate, and RGB converted to NTSC/PAL. For a standard VGA (640x640@60Hz) a line converter (only a FIFO memory) can be used to convert to NTSC. More details here.
