Hello Kristofor. I don't know if I can help you but I will try. I have an Spyder2Express, an I1Display and a Colormunki. For my experience, comparing these 3 instruments, I obtain similar results using the I1Display and the Colormunki, but different results (magenta cast) using the Spyder2Express. I have compared these sensors calibrating the monitor of a laptop (I don't know their retroillluminant technology but it is very thin), another supposed VA monitor, HP, an Eizo monitor with PVA panel and a S-IPS monitor from Dell. With all these differents monitors I see the same different results when I use the Spyder2Express, but not with the symptoms that you describe. Any of the tested monitors is apparently a LED monitor. I doubt about the laptop monitor. But seems that the LED technolgy involves how the panel is retroilluminated. I don't know if it is possible to obtain these bad results that you describes only to the LED technology. If you are thinking about to buy a new sensor, think that the Colormunki is supported by the fantastic application ArgyllCMS, as a device to profile monitors and printers !

My Fedora laptop (which has an LED screen) with argyllcms and with the OEM software on my windoze machine and a big honkin' CRT monitor. I recently moved, ditching the CRT in the process and buying a 22" LED screen by LG (sorry, I don't have the model number in front of me). My laptop also has an LED screen and I always had good results with calibrating it. Since buying the LED screen for my desktop, I've gotten really funky results when trying to calibrate it (using the stock OEM software). Everything was really washed out and the darks almost non-existant. My question is 3 fold: 1. Could my Spyder2 be dead? It was sent by train for >4000km and it's winter in canada....so everything was frozen pretty well. I haven't had a chance to re-run the calibration on my laptop to see if the same effect is present there. I would obviously back up my previous profile first... 2. Is this calorimeter just a bit too long in the tooth for new LED monitors? I didn't think so at first since my laptop is LED but it is a few years old and I'm not certain if the inlaying technology is really the same thing or if the desktop screen is more evolved. 3. If the calorimeter is dead I'm now in the market for a new one. I don't print but plan to do so soon and also it drives me bonkers to see my pictures blown out on someone's projector or hdtv. I've been leaning towards the colomunki photo as a replacement but wanted to have an argyllcms guru give their blessing before making any particular decision. A million thanks in advance and ttfn.
