Have you tried a DLP projector with a high-speed color wheel? When I still owned one, the sample-and-hold slide show effect was far less pronounced than it is on any LCD display I've used (assuming the same frame rate).
Yup, until just a few years ago I gamed almost exclusively on a DLP projector on a 120" projection screen when using displays outside of my CRT's. I miss it and have considered going that route again, that or picking up a nice late generation 1080P plasma.
