Thanks for the replies chaps.
I haven't had chance to try this on the PC yet due to spending pretty much all spare time building a media room.
You just know once I get this connected to the computer = hours of fiddling around!
I was going to use a HDMI cable but I do have DVI to HDMI cables around that I can try. This PJ doesn't have a VGA port...why don't they put dual link DVI ports on these things??
In the input menu on the RS40 there was a chioce of frame packed, side by side and top and bottom....no mention of checkerboard and I can't see any reference to chackerboard in the manual. If this is the case then I guess i'm stuck with gaming at 730p or 1080p/24hz
Whilst i'm here, in case anyone is considering spending out on something like this...ok, the image quality is nice, blacks are better etc but given the difference in price it really shows just how good that little Acer projector really is for the money. I got an incredible deal on this RS40 but having seen the two units side by side i'm not sure if I would pay full price for the RS40 over the H5360.
