Does anyone have experience with these or something similar?

Would you choose another brand or model?

Sandy B Ridge:
I've used an old Spyder on my old desktop PC. I read a bit about these on the yCMS forum on doom9 amongst other places. It seems there are two types of devices:

a spectrophotometer. This is the one to get because it has a wider gamut and more stable/accurate, but can be more expensive.

A colorimeter. Cheaper version of the above, but not quite as good.

That said, any calibration is better than none and the advantages of the spectrophotometer may not be that great with TVs versus a wide gamut 'photo' monitor.

Calibrating my TV for MadVR is something I keep meaning to get around to doing. There doesn't seem enough hours in the day at the moment.

If someone has done it, I'd appreciate a quick guide as to the basic steps involved too.

Thanks SBR.

The Spyder4ELITE features a full-spectrum 7-color sensor; I can only assume its better than the older models which weren't that great from what I've read.

Having said that, my TV has some great built in calibration options. Black and white clipping patterns help setting contrast and brightness but the built in stuff my TV has include color filters. With the color calibration test patterns I can correct red, green and blue individually.

I'm not sure what a calibration spyder can offer more on top of that.

I can get the black levels very good, probably near-perfect but white clips early (2 or 3 steps). No matter what I try, I can't get that correct. Maybe its impossible to get this correct, I don't know. But since the TV is hooked up to a PC, I would "think" a calibrated color profile should be able to fix that.

Sandy B Ridge:
What I gather is that the controls on the Tv can only set the top and bottom of the levels.  Usually only for combined brightness and not individual channels for RGB, so you are lucky there. Where the calibration helps is with multi point tweaking throughout the ramp curve.

Of course, ideally you'd get a man in to do a one-off professional ISF calibration of the TV to get the baseline and then do the calibration on the PC with a spectrophotometer. Starting out with an uncalibrated source and screen isn't ideal because you could be compounding the error unknowingly!

I have one, though I haven't used it for a TV yet.

My current HDTV at home is calibrated using PC software, which is annoying for a few reasons, but I haven't gotten around to using the spyder in this mode yet.
