The 8032's video output is at 20kHz which is not very standard. Luckily you can modify the CRTC registers and play with the timing. The best option is to change it to ~15kHz to match NTSC or PAL timing. At that point you can use a simple one-chip circuit to generate composite video ($2). You could also build something like my ColourPET circuit to generate RGBI or RGB analog for a Commodore 108x Monitor, or to a SCART TV (not all), or to a GBS82xx converter (video scaler)  ($25) to get VGA, or to a SCART to HDMI adapter (video scaler) ($30).
It's been on my to-do list for a long time to try the GBS adapter (I have one) and the SCART to HDMI (also have one). Someone else here successfully connected the PET to a GBS adapter. It's just a matter of tweeking the timing and the signal voltages.
