woomaster,

Factory reset your 4100 and post the results.

Hi Chris

I use powerstrip application on pc hooked up to my dell 3300MP to get custom res. on certain applications like powerDVD, I also noticed that doing 1920x1080i (HDTV res) the pic looks too green but doing 720p, the image is perfectly normal, I have reset the preojector many times to dell's defualt, but no luck.

I guess only way to fix this issue is by reducing green color in user defined color settings in projectors menu( think it works that way and I can cram up the brightess also that way).

I have done a factory reset and the picture is the same.  It is perfectly fine in 720p, it's only at 1080i that it's very dim and green.....regardless of cable length.

I've had a problem with seeing green using my 2200mp projector with my Dell tv. Dell says its not the TV and I believe them. I had to buy a converter box that finally solved the problem but there's something up with the way the Dell Projectors accept component signals (on the 2200mp i have a component to vga cable, I don't know about the inputs on the 4100). This forum and technical support has not been much of a help in this regard.

Well, actually I had a 3200 MP until the 4100 MP came out within a month after I bought it.  I only upgraded because it had a couple of extra features, i.e. dedicated component inputs and M1-DA input.  Dell sent me a replacement 4100 and it does the exact same thing.  I have taken it to 2 home theater shops and have determined that there is a flaw with the video processor in the projectors that I have had so far.  My 3200 ran fine in 1080, so I may see if they will let me downgrade to the 3300 and see if that is any better.

It's a box made by a company called VDigi Electronics called the VD-Z3 transcoder. It allows for a component signal to go vga. I initially bought it to use my xbox on my higher resolution vga monitor. Since buying the projector, my xbox now goes into my 2200mp. But when using the vga out of the projector into the vga in on my Dell 1900 lcd tv, I get a green flood (although 1 game passed through just fine). Using the VD-Z3 (component out of xbox to component in of VD-Z3 to vga out of VD-Z3 to vga in of 2200mp) I eliminated the green flood on my Dell 1900.

Hope this helps

Note: the image for the projector never had the green flood. Only the tv.
