Epson Powerlite 1815p screen projector - DVD playback video jerkiness when there is motion in the video

I'm trying to play a DVD video running over a 100 ft. ethernet cable from a new Dell Optiplex 745 using a ATI 1650 Pro 512 MB video card connected to the Epson 1815p screen projector. The video is then displayed on a 9x12 foot wall screen that is 19 feet away from the ceiling mounted Epson 1815p screen projector.

Epson Factory Tech Support is extremely poor, and I have basically given up calling them.

Powerpoint slide shows work fine, but DVD playback is bad with jerky display when there is motion in the video. Audio seems to sync OK, but with the jerkiness, it seems out of sync.

Everything else works just fine, this is my only issue, but my boss says that he will not use it until the video jerkiness is fixed. He's banned the staff from using the Epson screen projector until it is fixed also.

So I have basically a $3000.00 boat anchor until this video display problem is fixed..........

If anybody responds, thanks, and hope we can come to a concenus on the solution.

Re: Epson Powerlite 1815p screen projector - DVD playback...


I am assuming that the DVD plays normally on the display of the Dell 745.

Then the issue(s) may be with the:
1. Networking configuration/set-up of the Dell and/or the Epson;
2. ethernet cable;
3. configuration/set-up of the projector or the Epson itself.

A couple of things you can try:
1. Optimize your networking throughput.
1.1 Increase your PCI Latency Timer to 128 or 255 in the Dell's BIOS/CMOS setup (if present);
1.2 Try running DRTCP.exe and/or TCPOptimizer.exe appropriate to the Dell's OS;
1.3 Disable all other networking activities on the Dell. This may include auto updates, security/antivirus checks, etc. while running the DVD;
1.4 Slim down Dell's startup programs to bare minimum;
1.5 Increase your OS' swap file to roughly double your onboard memory
2. Try running a hub midway between the Dell and the Epson.
3. Verify that it is not the Epson that is problematic by playing a video source to the projector’s Video or S-Video port. If it is, then you have narrowed down the problem to the playing capability of the Epson.

Alternately if all else fails, perhaps you can try using:
1. a DVD player to the projector’s Video or S-Video port; and/or
2. a USB external DVD drive or a CompactFlash card (with a copy of the movie) direct to the 1815p
while settling the main issue.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

How do you hook up cable tv to my epson powerlite 830p lcd video projector

To hook up cable tv, you will need to have the cable running into a vcr 1st, then run either your s-video cable or audio video cables into the projector. Press the Source Search button on the remote control or the projector repeatedly until you see the image you want to project on the screen. The projector has two Source buttons.
Use the Computer/Component button to switch between equipment
connected to the Computer/Component ports.
Use the Video/S-Video button to switch between equipment
connected to the Video and S-Video ports.
? The remote control has four Source buttons. Use them to switch
between devices connected to the ports identified on each button.
(The PowerLite 830p does not support EasyMP.TM)
You can preview all sources on one screen to help you select the
desired source. (Allow a few seconds for the projector to sync up
after pressing the button.)

My Epson proxima is displaying pink. I did reset and replace cables and bulb. Any suggestions

I've seen the screen go pink when the video input is set to the wrong type (composite instead of RGB). Try each input type to see if it goes away.

One of our Epson PowerLite projectors was working

We found that the bulb was dim because it was about to burn out. The projector's filter han't been kept clean, causing it to run hot, which in turn shortened the bulb's life.

You have not set the port on the back of the projector settings.

Go into the projector menu and go into the IMAGE area. Somewhere in here you should be able to select computer.
