I'm also interested in this. I have the same problem. On my HTPC, I have powerstrip running to give me the resolution of 1280 x 720. I am also running my projector's overscann at 100%. Does this have an effect?

Doubling effect on HD1000 plz help
Hi! Its me again the infamous Vista+8800 guy. I have another problem regarding my display, I have this doubling effect using my PC where detail or any vertical lines or text will appear doubled in a fading fashion. By this I mean that if I look at a grid for example, every vertical lines will seem to have a very soft additional line between each 'real line'.
This gives the effect of text being followed by a shadow to the right and it's quite irritating.
Any ideas of what it might be? maybe it's present on my dvd too but I didn't seem to notice, I'll have another look later. But I have a feeling it might be something simple.

Nice, someone else!

I'm at 99% overscan, I don't think it has anything to do with it and I'm not running powerstrip mm...
I managed to reduce the effect by tweaking the gamma settings a little up, but I feel like the source is still there. Let's get this right osubob

What input are you using. It seems to be the worst for me when using the VGA input. However, I do se a very small amount of the "ghosting" when running HD through the HDMI. I can't compare apples to apples however, because my Laptop only has a VGA output. Oh, and I checked last night. I'm running 99% overscan too. However, it does not seem to have an effect if I change the overscan percentage.
Using VGA as well, might be part of the problem. Maybe interference of some sort? I tried using a laptop and it seemed to go away. It's like my HTPC sends too much juice to the PJ or something similar.
Problem is that I am forced to use VGA. Let's see what others have to say...

I know bumping sucks... but since I can't seem to get anything working properly with my setup, correcting things like these make my family much less frustrated at my insistence on getting a projector and not an HDTV
Thanks for your support guys, really need it.

Here is my thought after thinking about this for a while. Since we are using the VGA (Analog) input for the projector. There is a good chance that the signal is picking up intereference from an external source (power cable would be my first guess). I have all my cables wrapped tightly together to make things tidy. Now, if this is the case, we should be able to verify this by doing a few things:
1. Connect a laptop to the projector using a high quality shielded cable that is not in a close to the power cable.
2. Use the HDMI input using a DVI-HDMI converter. The digital connection should eliminate the issue since digital signals have a much higher resisitance to intereference.
I'll do my best to do some testing in the coming days and see if I can slove the issue. I'll keep you updated...

I just did what you suggested. All problems went away. But can't find any good shielded VGA cable... I just moved the cables away from their place. But that can't last forever.
It seems High end vga cables are not popular.

Mits HD1000u does not like 1280X720 via VGA on some video cards. Best you can hope for is XGA on some video cards. DVI->HDMI is your best bet to get stable 1280X720X60Hz.
Good VGA cable (but still cheap) can be found at www.monoprice.com or www.pccables.com . Don't go over 50 feet and avoid too many connections (extension cable, switchbox, male->female converter, etc.), and you should be fine.

I'm glad to hear that we are making some headway. I haven't had a chance to play around with my VGA conneciton. I have everything wrapped up in that spiral organizer. I'm not looking forward to removing all that and testing. The VGA cable that I am using is a pretty cheap one. I'm going to order a high quality shielded cable from Monoprice. All my other cables are from them and have worked great so far. Keep me updated...
