Guess I'll clarify first set up since I was tired and not clear. Matrix is a 2x4 connected to the outputs are the 24 inch monitor, and my 40 inch led. The sources are the PC, xbox, and ps3. The 24inch is a sony PS3 3d monitor so not sure if those count as monitor or tv. As for different resolutions I do notice when the PS3 switches to 720p for a game from it's 1080p menu I see the same behavior. The main display on the matrix would be the 24 inch screen I use it most often, and on the computer I use it as a primary with a 23 inch LED monitor connected through vga as I've been too lazy to get proper cables for DVI, or convert to HDMI.
