480p is still pretty good. I have an 8" HDMI 800x480 monitor and it was good enough for the 5D...stuff was never out of focus...Z-Finder not so much.
Good to know! That's what I was figuring!
Is it possible to set the T2i to output only 480 through HDMI so that I don't have to wait for the resolution to swap when i start recording?
