This would probably be a particular problem with displays like OLED that have very low level blacks. They have a concentration lens, have set maximum gain (圆4) and are almost using maximum integration time (714 msec, 716.8 is the max.), but the sensor count limits the dark resolution. The sensor they have chosen is struggling for light. The sensors auto zero function doesn't seem very effective in combating this. When cold I get a Y value of -0.014, but when it warms up to 25 degrees C I get black Y value of 0.054 cd/m^2. Maximum light level is theoretically 870 cd/m^2, although that could be increased by reducing the integration time.īlack point stability seems fairly poor. The Y channel values seem to be in 0.013 cd/m^2 steps. Low light level resolution seems limited. It instead has 4 calibration matrices for General, Standard LED, Wide LED and GB LED displays. I get consistent black measurements (but see below for caveats about black accuracy).ĭoesn't seem to have the spectral sensitivity calibration data that the Spyder 4 & 5 have, so can't be updated for new displays by distributing display spectral samples. Here's a preliminary critique of the SpyderX perfomance:Īccuracy: Seems OK, but I haven't done any detailed cross checking yet.įast: it always takes a little under 1 second per measurement.
