Neat!

The other day, I was considering how fast/good(/expensive) an ADC would have to be to capture VGA at say 1600x1200 24-bit @ 70 Hz... around 160 Msps with ~10 bits of resolution on 3 channels at least (RGB; a little lower res for VSYNC and HSYNC). Octopart parametric search says it would cost ~$40 for ADCs alone in small quantities (I don't have chip sampling vendor hookups anymore.). :'( This was going to be for a DIY IP VGA KVM because I was considering how to not spend $400-2000 on an actual new/used Avocent.

VGA is really easy to generate, most FPGA dev kits have a VGA Pong clone or VGA demo... so I can see how having HDMI would be awesome to have video and audio in the 21st century.

The TVP7002 only goes to 60Hz, but it does 1600x1200, is ~$4-$10 from digikey, and here's someone who figured out how to read from it (at very low FPS, far lower than it is capable of) with a microcontroller and (as stated) very little electronics knowledge: https://www.rpg.fi/desaster/blog/vga-framegrabbing-with-tvp7...
