Viewsonic Pro8200 Projector Review
We calibrate every home theater that we review. Thereceived the usual treatment. I “played” with the Pro8200 for a couple of days, passed it off to Mike for calibration and measurements. 24 hours later, I’m back to watching it.
Ours is a pretty standard calibration, there’s always more done by some of the “hi-end” calibrators. Our calibrations, including the Viewsonic Pro8200, are normally limited to a grayscale calibration, along with brightness, contrast, color saturation, etc. Only in very special circumstances will we calibrate the individual colors, in which case we discuss why.
Let’s take a look at the numbers:
Viewsonic Pro8200 Color Temperature
|Color Temp over IRE Range (Best Mode, Pre calibration)|
Before we provide our settings, let’s see what we started out with: Pre calibration, these are the color temperatures over the grayscale range:
|Brightest||1653 @ 7232|
|Standard||1529 @ 7718|
|Theater||1296 @ 7891|
|Dark Room||839 @ 7993|
|User 1||1108 @ 10280|
|User 2||1108 @ 10277|
NOTE: There are three other color temps in addition to Mid, but Mid gives the highest lumen output.
(By default, Dark Room is on Eco lamp. With Eco off, Dark Room has same lumens as Standard)
Lumen Output (Eco Lamp On, Brightest): 1306
That represents a drop from 1653 lumens at full lamp power. The math says that’s a drop of an almost perfect 21%. Most projectors drop 20 to 25% when going to their eco – low lamp, power mode.
Viewsonic Pro8200 Basic Settings
In addition to calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment.
|Settings for measurements (default values are in parenthesis)|
|Brightest||Standard||Theater||Dark Room||User 1||User 2|
|Contrast||(52) 50||(48) 50||(48) 50||(48) 50||(48) 50||(48) 50|
|Brightness||(45) 52||(49) 53||(49) 53||(49) 55||(49) 55||(49) 54|
|Color Temp over IRE Range (Post calibration)|
Average gamma= 2.18
