I have a HTPC going into the 990. From the 990 to my projector is a 30ft DVI run to my JVC HX2 projector. I am running the HTPC at a pixel perfect reolution of 1400x788 to my projector.

My problem is that when I run the HTPC through the 990's switch, it introduces these blue sparklies on the screen....and the longer it runs through the 990 the worse the sparklies get.

To make sure it is the 990 introducing the sparklies, I have tried different cables to no avail.... and also I ran the HTPC directly to the projector using the 30ft run and it gives a solid picture with no sparklies.

Is there anything else I can try? The 990 works fine on all other sources, like my oppo dvd player and my moto hd cable box. Is there a limitation on the resolution (or freq, sync polarity, sinc width, bp, fp) that can be fed to the 990? I am using exact resolution data from JVC to dial in the pixel perfect picture. I know I have read that the 990 is only a switch and should not introduce any artifcating, but I think it is a problem in my case.

Thanks for any help.
