I have a problem with Joytech Trilink HDMI switcher.

PC (winXP SP2 Matrox P650 graphics card DVI output) to input 1

Sony 970 HDMI to input 2

Joytech Trilink HDMI switcher output to Sony KDF-E50A12U HDMI

Picture quality from both the PC & DVDR fine but when I switch all the equipment off and then power up again the signal form the PC to the TV via the Trilink is lost and I have to reset the graphics card using Matrox Powerdesk.

Should the settings be retained by the Trilink even if it and all the equipment are turned off at the mains.

Any ideas welcome
