the initial greyscale adjustment reading is saying green is pretty high.
this is typical for a Panasonic plasma in WARM color temp, so the new meter is probably correct. what you should do is calibrate with the new meter, and then compare grayscale measurement you get on the "calibrated" set with the old meter. red will probably measure way off....
It is really a shame that these are such a disposable item.
well, you do get what you pay for. This is a sub $150 item being used for a task for which professional gear costs tens of thousands of dollars. It does suck that they can go out-of-whack after a year or two but, really, what should you expect? For $400-500 you can get a meter which will be more robust (e.g. Chroma5 or ColorMunki).
They are running a deal on the Monaco optix DPT-94 with calman home for 379. Is this going to be a meter that will last a while with proper care? Is it alot better than the display LT/2?
the DTP-94 is the predecessor to the i1 LT/D2 and is nearly the same, but it has slightly different hardware any may be a little more robust / accurate. It's not "a lot better". For more info, you should read through this thread: http://www.avsforum.com/avs-vb/showthread.php?t=958099
If you want "a lot better" and this is going to be a serious, long term hobby, stepping up to the Chroma5 or ColorMunki is probably the way to go. If you look at it as an investment vs. spending $130 on an i1 LT every couple years it's not so bad.... that's probably what I will do whenever my i1 LT bites the dust. Thankfully I live in San Diego so things are naturally temperature- and humidity-controlled so no problems yet after 2+ yrs
