Asrock ion 330 + benq w5000 projector.
#1
Hi.

I've read and tried several "fixes" for getting HD (720/1080p) to run without that annoying "jitter" every 3-5 seconds. Especially noticable on "panning scenes".

There are no dropped frames it's just a "jitter".

My Asrock is connected directly into the BENQ W5000 projector and the BENQ W5000 is displaying the asrock as 1080/60p and i find no setting on the projector or the Asrock bios to change that. Could that be the problem?

I've added the DynamicTwinView False to xorg and rebooted. When that was done i could choose 24hz in XBMC, but still same problem.

I've also set the X11 refresh to 24hz, but still no luck.

So what I'm left with is to try hooking the Asrock into a reciever and from the receiver into the BENQ W5000.. Will this fix my problem? And is that the only fix available?

Here is a sample of my xorg.conf file:

I would add:

Section "monitor"
Option "ExactModeTimingsDVI" "TRUE"
Section "Device"
Option "ModeValidation" "NoEdidModes"

and disable compositing.

Section "Extensions"
Option "Composite" "Disable"
EndSection

I did a complete new "nvidia-xconfig" to get a default xorg file and added what you mentioned.

It seemed to fix my problem but i had to remove that EdidMode stuff.. it didn't let me jump into 1920x1080 in X. It does however seem to have worked. Will test abit more.

Thanks!
