Those "color controls" you were adjusting are not for adjusting the colors in an image. They are for setting the underlying color of gray. It's a common mistake when one confuses color decoding controls (saturation and hue) with...

That's a great experience to have! Congrats. And think of it.... future projectors will be even better in image quality. Work next on reducing the room's interference with the picture. Darkening the surfaces in the room will give you...

Get the room completely light controlled. Also try to reduce the backscatter of light from the walls, ceiling, and floor onto the screen. Once you do that, you'll be quite pleased with the Carada BW. If there is ambient light, the...

1. Brightness not contrast is used to affect the dark portions of the image. If the above is not your problem then one of two possibilities are present. A. If connected via an analog connection, the DVD player is set to enhance...

My guess is Macrovision on the DVD disc. Does the same thing happen when you put in a DVD that doesn't have Macrovision like Avia? If not, then it is likely Macrovision messing with your switcher's video circuits.

Periodically, I hear people struggle with setting contrast. In particular, people get hung up on looking for blooming, avoiding geometry distortion, or thinking that the AVIA disc is only for CRT displays. Here's the five minute summary...

Unfortunately, merely lower picture brightness has only hidden the redness problem at the cost of also lowering some shadow detail into oblivion. You display has a grayscale calibration problem at the dark end. It isn't keeping all...

It if doesn't move with the image as you adjust HPOS, then it is unfortunately a phosphor burn. A signal noise issue would typically shift left/right with the HPOS control. Do those two narrow, vertical dark bars on the left move with...

I don't believe it is burn-in of the phosphor. That would be visible in higher APL material and more difficult to see in low APL material - the opposite of your situation. The artifact is more likely low level noise that is now visible...

Spray the microfiber. If you spray too much on the screen, some of it will dribble down below the screen frame. Once it reaches the bottom edge of the front screen plastic, it will wick up and in between the fresnel and lenticular...
