IME, most manufacturers of HDMI switches are incapable of making them work correctly - unless they do NOT include and automatic switching mode. Apparently they think everyone who uses them turns HDMI devices off when not in use (selected as the output by the switch). The only one I've ever encountered that works reliably has no automatic switching function and is a long ago discontinued model. Other than returning the switch as "defective", I can only think to suggest two things: 1-power off all HDMI sources except the one you wish selected, then cycle the power to the switch. 2-manually configure Xorg using xorg.conf to exclude possible modes except 1920x1080. (Set PreferredMode, and set HorizSync and VertRefresh to narrow ranges that can only compute to the 1920x1080 mode published in the manual or provided by EDID when connected without the switch inline). -- "Wisdom is supreme; therefore get wisdom.
