Just to doublecheck. The tutorial says specifically to set the sensor to LCD instead of CRT. It also shows the sensor mounted with the LCD filter installed. Is this REALLY correct? How come?

Correct.

The display type has more to do with whether the display is a projector or direct view it seems.

Btu the real reason: I tried it both ways and got crazy readings when I changed settings. Smile

The readings I get when set to LCD and the filter on match exactly what I was getting with a Minolta CA-100 colorimeter.

Try it both ways and you'll see that the readings go crazy the other way for a projector based setup.

Hm. From feedback I got on the AVS calibration forum, I thought you were supposed to have the filter OFF. I wonder if that's why I get such bad results from mine (I had to calculate a correction matrix to get my Spyder to match my Minolta TV-2150) and why it's so unusable when pointing at the pj. I'm out of town for a few weeks, but when I get back I'll have to dig out the filter and try it again. Thanks Kal!

I may be with the advantage of not really following the other threads or rules over at AVS. Smile

I simply tried all of the different combo's and had readings from the Minolta CA-100 so I knew what I should be seeing more or less. Facing the Spyder2 sensor to the screen and keeping the filter on was the only way I got readings that were anywhere near correct. Everything else was so off it was obvious.

To be clear if possible.

I've read so many pro and con treads about the filters and just want to try to clear this up.

There is a filter that has a clear plastic lens and then a defraction grate honey comb looking thing in front of it and this is what I would call the "filter."

There is also a opaque white part of the sypder that I suppose could also be called a filter. That one you don't remove without using like a little screwdriver or something. With that off the readings I got were crazy. I don't recommend using the Spyder with that filter off.

The other one didn't seem to make that much of a difference to "my" readings but since it would cut light not coming in on axis it looks like a sense-able thing to use.

I can't see how anyone would be calling the opaque part the filter as you'd need a screwdriver to remove it. Th Spyder2 software will tell you to remove the honey comb thing depending on what type of display you're using but from what I've read, the Spyder2 software then compensates for the differences so you can't use the fact that their software tells you to remove it to mean it should always be removed. The HCFR software does not compensate so you have to leave it on all the time.

But then I haven't read as many pros/cons about it as you Brian. So any input is welcome.

I changed what's in the write a bit too as from what I read, you leave the honeycomb/blue filter on *all* the time when using HCFR.
