I have a Samsung LN-T4665F which I am trying to calibrate with Spyder2, HCFR, and the GetGray DVD. The Spyder2 is not properly measuring color temperature. If you calibrate the TV so that the RGB graph is flat, the gray bars are quite noticably pink. If you set the TV so that the grays actually look neutral, the graph shows about 9000 deg temp, and the RGB graph is way off. I've eliminated a lot of the potential problems:

1. It's not the Spyder2: I bought a second Spyder2 which yielded the same results, and at least one other person on this forum had the same exact problem with their measurements using Spyder2/HCFR/GetGray on the 4665F. Also, the Spyder2 yielded perfect measurements on my matte computer LCD.

2. It's not the GetGray DVD: I used gray patterns from DVE which yielded the same bad results on the TV, and the GetGray DVD worked fine when measuring my computer monitor.

3. It's not the DVD player: I used my Denon DVD player (via component) and my PS3 (via HDMI) on the TV - same results.

4. It's not the panel or the firmware: Another forum member was able to get good results with a Spyder2, HCFR, and a matte Samsung LN-T4661F. I'm pretty sure it has the same panel and same firmware as the 65F - just not the gloss. It doesn't appear to be anything specific to my TV either, since the only other one that I know of who is using the Spyder2 to measure a 65F has the same issue.

Bottom line: the color temp on the TV appears to be fine. When I calibrate to neutral grays by sight, the tone is Warm1 with a few White Balance adjustments. The picture looks amazing and the colors are very accurate (even according to the Spyder2 - it's the gray scale, color temp, and gamma measurements that are off).

I did find some vague Google references to glossy LCD screens being hard to calibrate, but I haven't seen anything linked to the Spyder2. Can anybody confirm this to be an issue?

Also, the Spyder2 yielded perfect measurements on my matte computer LCD.
And you know this how? Without a reference instrument to compare it against, at best all you can know is that any inaccuracies are not so obvious as to be evident to the naked eye.

The Spyder2 has one feature to recommend it and one only: Low cost. You get what you pay for.

There are other devices that are considerably more accurate over a wider range of displays, some of them not that much more expensive than the Spyder2.

I didn't mean perfect in terms of accuracy... what I meant was that the measurements made perfect sense. A flat graph yielded grays that look neutral. On my TV, a flat graph gives you very pink gray bars.

I don't want to turn this into a Spyder2 topic - I'm well aware of the limitations and compromises. Also, I don't want all the gloss-haters that hang out in the Samsung LCD threads to make it about gloss vs. matte. I just want to know if it affects the Spyder's readings.

One thing you might try is to remove the baffle on the spyder which contains a filter and try CRT mode. While this may not be the optimal set-up in terms of LCD vs. CRT, if it yields better results then you can conclude that the problem is multiple reflections between the filter and the glass. Also, make sure the probe is as close to the panel as possible. This is especially important for LCDs because their off-angle color production can vary and the spyder has a very large angle of view.

I've found this to be the case with every LCD TV I've tried calibrating so far with the S2 and to a lesser extent the D2..both aren't very accurate when doing LCD tv's. I thought by now more people would have come accross this and a solution be found...but obviously not yet...other than go out and buy an I1pro....which for hobby sakes is a bit too expensive!

OK, it's not a Spyder2 problem & it's not a GetGray problem & it's not the DVD Player or the panel or the firmware 'cause it's cherry. That leaves only one possibility - you're jinxed when it comes to calibration, so give it up before you hurt yourself.

Seriously, there's only five or six possibilities & you've ruled them all out. Oh, and stop trying to use html - check out the markup codes on the left of the edit page.
