A friend of mine just bought an Optoma DLP front projector. I don't know the exact model, but he said he got it at Best Buy for around $1,300. I think it's the EP739. I went over to his house to play around with it, and was amazed at the picture quality. He has it set up just projecting onto the wall at about 25 feet away, and the brightness and picture quality is stunning. The size of the picture and the sharpness completely blows away any television that is 3 times that price. He has the dvd outputting from the HDMI source from the player, and coming into the digital input on the projector.
Anyway, this was my first real experience playing around with a projection system, and I had a few questions.
1) I popped in the Avia calibration DVD to calibrate it. Contrast and brightness was a snap, and I couldn't find a sharpness control in the projector menus, but sharpness looked good anyway. The real problem I had was trying to calibrate the color. Instead of the normal Tint and Color controls that a TV has, the only way to adjust the color was to adjust individually the Red, Green, and Blue levels. By using the 'Blue Bars' test pattern with the flashing squares, as you would a normal TV, the only way I could get the squares not to be visible through the blue filter was to pump up the blue very high. According to the DVD, the color was calibrated, as when I looked through the blue filter, the flashing squares were no longer visible. However, the picture looked terrible. It was way to blue; things that should have been silver were turquoise, and the colors were very muted. How should I go about calibrating this? Is the process different, since i'm not adjusting saturation and hue? Do I need to use the other colored filters that came with Avia? Also it seemed that each color adjustment seemed to 'cap off' at a certain level, i.e. after I adjusted red past a certiain level there was no visible change even though the value kept increasing.
2) He was projecting onto a wall, and doesn't have the budget right now for a good screen. He wants to paint the wall, but doesn't know what type or color paint to use. Should he use a glossy reflective type, or a matted non reflective type. Also what shade should he use? Pure white or more silverish?
3) The projector can do both 4:3 and 16:9. When projecting in 16:9, it basically uses the bottom half of the 4:3 area to show the image. Is there any way to change it so it uses the middle or top area for this? I couldn't find this in any of the menus.
4) Finally, does anyone have experience with this particular projector? I'm just wondering what the general pros and cons are for this model. I was until recently really sold on getting a DLP rear projection TV, but now I really think I want to go front projection. The quality and size of the picture can't be beat for the price. Is this one a decent projector?
Thanks in advance for any help!
