I've now tested this on 3 different sets with identical results each
time with Samsung spouting the same "get a replacement from your
retailer" reply. It obviously needs a fix via a firmware update, I've
seen the same fault with both v1007 and the most current 1009 updates.
If you connect a PC (outputting 1920x1080@60Hz) to HDMI1/DVI and label
it as either "DVI PC" or "PC", the TV will intermittently apply a blue
overlay to the display. I've tried it with a PS3 also just to check
it's not the 3 different PCs that I've used, and the PS3 was the same.
It never does it if the input is labelled as something else (BluRay,
Satellite etc), but then that doesn't enable "PC mode" with smooth text
and no over scan etc.
<b>Attach a PC via HDMI 1/DVI
source as PC or DVI PC (to put the TV into "PC mode")
Select a regular source
on HDMI 2, 3 or 4
Power off TV
Power on TV (TV should be on the HDMI
source you selected before powering off)
Switch to HDMI1/DVI (a blue tint
should now be covering the entire screen)
Cycle the power again to get rid of
