I have the filters that came with DVE and a pair of the THX glasses. I usually use the DVE filter but when I tried the THX glasses the results for color&hue were different. The THX glasses are not as dark and a little more purpleish. Which one is more correct?

Greetings

The THX glasses are supposed to be the most accurate ... but many have said that too. There is still variation between the producers and the production lots.

Blue filters are still based on CRT primaries ... so when used on non-crt devices ... the results may vary from great to not so great at all.

Bottom line ... blue filters are only tools and not meant to be the final answer for color and tint.

As Michael said, there are slight variations from batch to batch, and all plastic filters can change with age (especially if they are not stored in a dry, cool environment). The "standard" is the Kodak Deep Blue Tricolor #49B, which the THX glasses and the AVIA blue filters (and the Lee Tokyo Blue #071 filter) approximate.

The DVE blue filter is different (a darker blue filter) and seems to do a better job on some Plasma displays. The DVE blue filter seems to also filter out more UV wavelengths which some Plasma displays emit, and has been reported to give better results for those displays. You didn't mention what kind of display you are trying to calibrate.

For the LCD & DLP displays (flat panel and front projectors) that I have, I found no difference between the settings of the Color & Tint controls with any of the 3 (THX glasses, AVIA blue filter, or DVE blue filter). This assumes that the Brightness (black level) & Contrast (white level) has been correctly calibrated first (necessary). The THX glasses are much more convenient to use, IMHO.

NOTE: If the Contrast (white level) is set too high, some displays will introduce a tint into the grayscale. This will prevent proper Color & Tint adjustment. The more correct the grayscale is, the better the Color & Tint adjustment will be. Also, not all calibration discs are completely accurate either (you didn't say which one you are using either).

I am using DVE to calibrate a 60A3000 SXRD.

Using a Blue Filter on anything other than A CRT you are just screwing your TV.

You need a Blue filter that is matched to the Color Temperature of your Light Source. So DLP that uses a Noble Gas Bulb, is different than a Compact Flourescent LCD, which is different than a LED LCD.

If you want to adjust your color use a device, or just eye ball it. The more scientific a tool you use for an un-scientific approach, the more wrong you are likely to be.
