Problems on projector playback
I have a Thermaltake DH102 case with incorporated LCD monitor.
My motherboard is an ASUS M3A78-T with AMD 860 Phenom CPU and 2Gb of RAM. I am using its IGP (ATI HD 3300).
DVD playback on internal LCD monitor is fine. When I attach a Sanyo PLV-Z4 projector (1280x720) straight through hdmi, it is recognized properly but the image is not steady, as if it has interference or loses hdmi link.
The hdmi cable is 14 m long, but it's Monoprice top quality cable and I did not have problems with it in the past even through a receiver. Furthermore, in the past I was able to link the above projector to another HTPC and I never had HDMI exchange problems.
I installed the latest ATI 9.6 driver. That is the no. of the whole utility, as in reality the driver number is 8.6 dated May '09. I did not install ATI Catalyst Control Center. The previous driver version was giving me the same problem with CCC installed.
I doubt the problem is the cable.
Is there something I can do to make it work?
Is there some special setup for this motherboard?
Any recommended set-up in the MB bios?
Any utility that might help me?
Thanks in advance.

Is your projector connected to a receiver before going to your HTPC? If so, I have the 780G version and I know it has issues outputing to a receiver (video blinks in and out) using the HDMI port.
My LCD incase monitor is set as primary and projector is set as secondary with extended desktop.
From PC I go straight to projector by HDMI.

Sorry couldn't resist.
But seriously, have you checked to make sure the refresh rate is 60hz and set the resolution to 1280x720 just to check if you are feeding the PJ a signal it can process.

The hdmi cable is 14 m long, but it's Monster Cable top quality and I did not have problems with it in the past even through a receiver. Furthermore, in the past I was able to link the above projector to another HTPC and I never had HDMI exchange problems.

Does the problem vary depending on the content or video source you are sending to the projector?
If video what program are you using to play what resolution video?
Are the Icons you use for programs you use on the PJ on the extended desktop?

Nosferax,
I checked 1280x720 at 50Hz and 60Hz. I am in PAL land.
Given the result, obviously I am not 100% the projector can deal with the signal I am feeding.
Cable is good but perhaps these two devices cannot handshake properly.
BTW, I made a mistake is "Monoprice top quality cable"!!!
walford,
problems do not depend on the video source I send, but on the initial handshake between devices. Indeed, they start as soon as I make the 2nd display active at [email protected]
Afterwards, my usual procedure is to move PowerDVD window to 2nd display and begin playback.

It maybe an HDCP problem. The fact that you have two display active at the same time may give PDVD some problem managing the DRM.

The fact that you are in PAL land certainly makes a significant difference especially if you are not sure if it can accept 720p/50 instad ot 720p/60.

Nosferax,
it cannot depend on PDVD because, as I said, the problem begins as soon as I make the 2nd display active, even before PDVD is on.
walford,
I tried both settings - at 50Hz and 60Hz. No change.
