Part Number: DLP2000
I've been testing DLP2000 with beaglebone for a few weeks, but all the videos show really slow.
I'm working with a debian version with graphical desktop from SD card.
Is there a way to fix the frame rate?
I guessing it is a beaglebone issue and not the DLP, maybe using another debian image?
Thanks in advance.
If you are seeing slow framerate coming out of the BeagleBone Black, it is very likely due do the software renderer that is employed by default on the standard Debian installation. The DLP chipset itself runs at a fixed 60 Hz, so framerate throttling is not an issue.
In order to get proper hardware graphics support on the BeagleBone Black (so you don't have to use software rendering), you should look into installing the associated graphics drivers for the system (PowerVR SGX). There are some resources within the BeagleBoard community which may help you:
I hope this helps.

I followed the forum steps and succesfully launched Powervr consumer services also installed the SDK.
But now i can't display anything, when i try to export DISPLAY=:0 and apply
mplayer -fs ./videos/Horsevideo2.mp4
I receive a reply "SDL_Init failed"
Error opening/initializing the selected video_out (--vo) device.
No video or audio streams selected.

Thank you for your patience. We will look into this and get back by end of week.
In reply to Vivek Thakur:
It sounds like there is a problem with the initialization of the PowerVR service/video driver.
I recommend that you seek help from the BeagleBoard.org community forums for more in-depth help for this sort of debug effort. Since this becomes a Linux/Debian problem more than a DLP problem, our assistance for these kinds of issues becomes more limited.
