Monoprice HDX-501, Sanyo Z3, ATI 3450

[darman]

I purchased a Monoprice HDX-501 and have 3 HDMI inputs connected (HR20-700, HTPC (ATI 3450) and Vudu). When switching between the three the HR20 and the Vudu appear as expected. When I switch to the HTPC the colors are washed out and the screen is quite bright. I have to open the Catalyst Control Center, change a setting (i.e. 32bit to 16bit color) for the screen to look proper (once the change confirmation appears, I click don't keep new settings).

I have not been able to rectify the problem. Any ideas on what is causing this? Suggestions?

Thanks

Most likely it's the drivers for the computer video card, which has less tolerance for losing the signal to the display, because that's uncommon for a computer. You need to take that up with ATI.
