Optoma HD23 – Full Specifications Naturally, we calibrate every home theater that we review. The Optoma HD23 received the usual treatment. This time, Mike got to calibrate it before I really started watching the HD23. Since Reference and User seem identical. I could compare Mike’s finished calibration results with the out of the box default by comparing User (post adjustment), to Reference. Our calibrations, including the Optoma HD23, are normally limited to a grayscale calibration (adjusting the balance of Red, Green, and Blue), along with brightness, contrast, color saturation, tint (where applicable), etc. We rarely calibrate the individual colors on lower cost home projectors like the HD23. That’s a moot point in this case, as the HD23 lacks a full CMS with that abililty. Let’s take a look at the numbers: Optoma HD23 Color Temperature Color Temp over IRE Range (Cinema mode) 30 IRE 7991 50 IRE 8078 80 IRE 7840 100 IRE 7773 Before we provide our settings, let’s see what we started out with: Pre calibration, these are the color temperatures over the grayscale range (repeated from the Performance page): Lumen Output and Color Temp at 100 IRE (mid zoom) Cienma 1081 @ 7773 Bright 1045 @ 9291, 1176 @ 7892 on Warm color temp, 1319 @7983 with Brightness on default of 50 Photo 1045 @ 9045 Reference 736 @ 8578 User 736 @ 8578 This shows the default brightness of each mode, and the color temperature of white (100 IRE) that we measured.

Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment. Lamp Mode= Bright (unless noted otherwise) All other settings are default 1. Optoma HD23 Home Theater Projector Review - Optoma HD23 Projector Highlights - Optoma HD23 Projector Overview2.
