I wasn't in the market for these because I didn't want to fall into this rabbit hole, but they were both free, so I couldn't argue with the price. The problem is, I have no idea how to get my consoles hooked up to these. The bigger one has an S-Video connector, so I was able to test it with my Saturn. Picture seems ok, but there is discoloration on the bottom right corner. I tried degaussing it twice, and it only improved marginally.
Time to do some research to see how I can get some systems hooked up to them for further testing.
