I sent the e-mail below to Spectracal. I would like a comment from them or other users.
As a purchaser of one of your products I received an email last week titled "Time to Upgrade Your Colorimeter!" . At the bottom of this email, under the heading ”What meter is right for me?”, is the statement that the C3 meter is accurate only with LCD displays (and the accuracy tables are footnoted as applies to LCD displays only). This information is at variance with the information disclosed to consumers elsewhere on your web site. See this page: http://store.spectracal.com/consumer/c3.html
. Note that this page states that the C3 supports plasma. But if the C3 in fact does not support plasma, as your latest communication states, that would explain why I get an unacceptable picture on a Panasonic plasma when I use the C3 with Calman software. The picture has a noticeable green tint. Twice I returned this meter to be checked by you, but you found no fault with the meter. Of course, you would find the meter accurate, and I would find the calibrated picture inaccurate, if the accuracy if guaranteed only with a LCD display.
I relied on the information on your website in making the decision to purchase the kit. As a result of the inaccurate calibration with the C3 kit, I subsequently had to have the TV professionally calibrated.
If at its price point the C3 cannot support both plasma and LCD, but one or the other, you made the wrong choice. Plasma buyers are the ones fanatic about picture quality and would be the target market for this product – not LCD buyers!
