PaulB loaned me his SpyderTV calibration tool, and it comprises a colorimiter and software to calibrate your direct view display (which includes CRTs, LCDs and DLPs, as well as plasmas). The software is wizard driven and will choose the best settings on your display to what it considers optimal. That's fine as it stands, but you don't know what these settings are in relation to D65 - it might still be innacurate as far as D65 is concerned, but optimal for what controls the tv has available. However, there are some other Colorvision software packages available, as well as a 'back door' option with the SpyderTV software that allows you to see the raw colourspace data in the form of x,y,Y co-ordinates. They relate to the CIE chart and black body curve and indicate how far you are from your selected white point (D65). I tested the STV colorimiter alongside Colorfacts with the Trichromat-1 colorimiter, and it is possible to get very close results that are comparable, so it is possible to use this to calibrate to D65, but with some extra legwork involved (since the software isn't as helpful as Colorfacts is). You can put the values into a spreadsheet here: http://www.keohi.com/keohihdtv/isf/michaeltlv/isf_m-tlv_calibrationreport_michaeltlv_v3_page1.html Because the co-ordinates that are derived from the STV software are only accurate to -2% to -4%, the results you put into the spreadsheet (downloadable from page 2) will mean your settings will be innacurate by that amount. However, if you change the target values to the values that I measured whilst reading my DLP @D65, the results will then be closer to 100% accurate. In the spreadshet it has target values of x=0.313 and y=0.329. Depending on the software you decide to use, will depend on what values you will put there, but the supplied STV software will require something like x=0.301 and y=0.322. You will have to use a division to get the luminence value closer to an accurate figure so that is there too. I can/will supply more info but feel free to ask questions or point out any errors etc (Gordon et al) so we can make sure we get better results and as close to D65 as possible. For £200, this could be Colorfacts Hobby rather than Colorfacts Pro. I've enclosed an Excell spreadsheet of all the data I took so you can see what Colorfacts read and what the other software read. I can supply links for the other software and eithe PaulB or myself can help point you to other threads over on avsforum if you want more info. I have measured my CRT monitor too, and with one particular software, the data was about as accurate as it needs to be, so if a CRTs projected light spectrum is the same as a CRT monitor, then with the right software it should be possible to get accurate results straight from the software without any adjusting etc. Gary.
