Where or who are you guys recommending I purchase the DPT-94 probe from ?

Thanks

Just had mine delivered today from warehouseexpress, but after checking shipping for you they only ship to the UK.

The package i got my monaco optix XR (DTP-94) in is called Colour confidence studio XR, which i belive is the last packaging for this sensor.

You get a lot of freebe software and stuff with it, which is a bonus for the price!

Do a search for the above and you should hopefully find a supplier over there!

All the best!

In the US, it's sold as "monaco optix XR". XR is the key, as without it it's not the latest meter. Use froogle/google to locate one at a resonable price if possible. I think someone got a new on on ebay for a decent price recently.

Thats the exact model i got in my package "Monoco optix XR", missed the xr off in 1st post so now rectified and same as in UK also.

There is one "used and new" on Amazon that looks about right for $175, but I'd contact the seller to be sure it is the right product. Chromix.com also seems to have a few of the "XR Pro" left at a significantly higher price. I have had positive intereaction with the folks at Chromix.com, though.

Does the DTP-94 offer anything in the way of performance that you can't get with the GTM Display 2 at a significantly lower price?

The dtp94 differs from the D2 (display 2 or LT) in several important ways. there have been multiple threads on the subject both here and at http://www.datapopuli.com/forums/.

probably most importantly is the d2 apparent issue with plasmas and IR (infrared light).

GTM is transitioning to the D2 family and the dtp94 for all intents and purposes is discontinued, unfortunately. I do not know the details of the D2, but would like to hear about the following from anyone that knows (and can say):
1) does the D2 have a temperature correction table like the dtp94 does?
2) is the D2 autoranging?

No the D2 does not have temperature compensation, like the DTP-94 does. Yes is does have autoranging and is very fast.

The problem with the D2 is the internal calibration table for CRT just does not work well with the Plasma since the spectral distribution is just different enough. In my testing with a 42PH9UK the DTP-94 was closer to the i1Pro than the D2 was, still not perfect but much closer. The problem with the DTP-94 is it needs to be dark re-cal'ed often, which means getting the same position is a little more work. I use painters tape to mark it so I can place it back in the exact same place each time. The other is since it has been discontinued it's getting harder and more expensive to find. We do have plans in v3 to help the D2 out with Plasmas but have not worked out the logistics yet. We are also researching other tri-stim meter solutions. I'm running out of desk space for all these toys :) After v3 has shipped I will take a picture of my lab.

Thanks to all of you :), most helpful. The product search and "XR" verification is on.

Just to update I finally found the "Optix XR" for $179 at a store in Rochester NY (home of AVS :)).
I didn't ask and I should have but I think they have more in stock at this price.
Just call the number at the top of the link page, I spoke with Cory who seemed a really nice guy. Free shipping..

Derek,

Just so other readers will understand the fact that in your case the measurement accuracy was closer with the DTP-94 vs the D2 on a specific display does not indicate that it is generally more accurate on a wide variety of displays or even on other plasma panels! I know that this is not stated by you in your post however I thought it might be nice for others to observe this fact.

The accuracy or inaccuracy is largely determined by the colorspace of the display under test and how well the analyzer being used correlates with that colorspace. This means how well is the CMF (color matching function) designed for a wide variety of displays. If the filter set intalled in the analyzer does not work well with a specific display there is very little that may be done to correct it to achieve more accurate data.

According to tech support at X-Rite the D2/LT are temperature compnesated in the chip design itself to a certain extent. They will provide me with the specification/tolerance that it works well within. The DTP-94 uses an op-amp which is why it must employ some sort of temperature compensation. This in and of itself does not insure greater accuracy per se.

Yes according to tech at x-rite but have you tested it, I have. In my testing I know for a fact I can get the D2/Gamma5 to drift with ambient temperature change, where the DTP-94 is less susceptible to ambient temperature drift. This is a problem with panels that can produce large amounts of heat LCD and Plasma, with direct contact. Measure the surface of one of these and you will see as much as 15 deg over ambient. So you take a meter that is at ambient (room temperature) and as you are taking measurements and it is acclimating to the surface temperature of the display it's reading will change. The DTP-94 is very good at holding across a wide range of change, the Display2 is not bad, the Spyder2 can be as much as 10%. So our recommended solution for these meters is allow the meter to acclimate to the display surface before taking readings. I'm not saying one meter is better than another just stating what my research has found.

I agree with you that you should be able to get a stabilized reading if you leave the probe on the screen surface for a long enough period of time. By simply logging the measured values to see if they become repeatable over a period of time would be an easy test to do.

We do not use the D2 although we support it with our software. The probe which we use does not seem to exhibit the same response to plasma panels which you have noted. I believe part of the reason for this is due to the use of a baffle placed ahead of the detectors which on our piece places the detectors further from the plasma screen surface and less sensitive to the heat then the D2.

In the testing which we have conducted on a number of plasma panels we have consistently maintained a deviation within .002 for both x and y relative to our reference PR-650 or Minolta CS-1000A.

Sorry, but this post confused me :confused:
When you say "The probe which we use" and "within .002 for both x and y relative to our reference", are you referring to the ProgressiveLabs C-5 or something new?

jdbimmer,

Yes, I am referring to our current C-5 model probe!
