I've been looking at colorimeters, and it seems that all the budget level ones (below or around 100, ie spyder2) measure by sticking itself onto a TV screen to measure with its measuring side facing the side that its sticking up against.


However, what happens if you want to calibrate a projector? You obvious can't stick it up against the screen, cause the sensor won't be able to pick up any signals... so how?

also, can you please recommend some cheap ones ($100-) or other ways to calibrate without spending money to be a colorimeter.


thank you.

The Spyder2 can be tripod mounted and then pointed at the screen.

This is how I do it for a ceiling mounted PJ; some others may have different preferences.

The room must be completely dark; even bright LEDs from equipment in the room or from your laptop may effect the readings if the light from them reaches the screen.

Mount the S2 on the tripod with the S2 about 1-2 feet from the screen, and between 1/3 to 1/2 of the screen height. Angle it up slightly to avoid reading it's own shadow and face it straight r to l.

Put up an 80-100% intensity white window and take continuous readings. Fine tune the aiming of the S2 to get the maximum luminance reading. Then you should be ready to go.

The Xrite Display One and it's variants is better than the S2 sensor, but it is a little higher than your price range.
