Sorry for the delay..I had some really nice, small, simple testpatterns aaaaand I erased them a few weeks ago of course. All these tests will work best in a dark room with the projector sharply focused. Getting these four settings looking right will often make the biggest difference of any setting calibration. It is also recommended that you turn off any spacial features like dynamic contrast, dynamic black, brilliantcolor, real cinema, smooth motion, etc.. as these can make the display more inaccurate and often come with other problems as well.
They are fairly strightforward to use.
Brightness can be set low enough that the black surround and one little square on the left is as dark as they get, but also high enough that the next 16-17 don't also look pitch-black. Too high makes black look grey, too low makes the entire image start to turn black.
Contrast is the same thing flipped. Turn contrast low enough that you can see a difference between the white outside edge and the spot to the left of 254. Too high and the whole bar will start to turn white, too low and your brightest whites will be dimmer than they could be.
Color clipping. The color squares should have smaller squares visible inside that get gradually smaller at a regular rate. As you turn Color higher, the bigger squares will start to disappear into the biggest one until eventually the entire thing is just one solid red,green,or blue square.. Turn the color control down until you can see all the smaller ones inside. NOTE: the left side is usually the easier one to judge by..the right side is a little too gradual for many displays under $2000 to easily watch without squinting.
Sharpness should usually be set quite low (often nearly all the way down) and turning it higher will slowly add little white lines near the edges of the black lines in the sharpness patter. Corners can be especially telling. The idea is to have it as high as possible without seeing any little white/light.
All these images can be opened in Paint that comes with windows or any decent picture browser. They are .bmp because the more common jpeg and most others like to "adjust" your colors and tones every time you save or move or upload the image and it's pretty important that the colors and everything stay exactly as they are for obvious reasons.
