I recently replaced my old projector (ViewSonic PJ503d @ 800x600 over VGA) with a new HD projector (Acer H6510BD @ 1920x1080 over HDMI) and have been having trouble getting some videos to play smoothly. Audio seems fine and is connected over a plain 3.5mm stereo connector to an old Creative Labs SoundBlaster card.
The PC is running Ubuntu 14.04LTS on an AMD Athlon II X2 245 (Regor) with 16GB DDR2 800 and an onboard GeForce 8300GS. I have never had issues playing back anything h.264 or older at any resolution, including raw BluRay transport streams, on the old display. I'm now seeing issues with both HD and SD video.
Not sure if it's relevant or not, but I also have a problem with a garbled display if I power on the HTPC prior to powering on the projector.
Nothing has changed except the projector itself and the connection between it and the PC (going from VGA to HDMI). Is this something to do with HDMI syncing or some kind of HDCP problem? Not sure what to make of it.
