Vivitek H1080FD Projector Review
Vivitek H1080FD Calibration notes: We calibrate each home theater that is reviewed. Our calibration is pretty standard. A professional calibrator will do a good deal more, although we cover the items that cause the greatest improvements.
Vivitek H1080FD Color Temperature
|Cinema: Color Temp over IRE Range:|
|30 IRE||6961K (dark gray)|
|50 IRE||6912K (med gray)|
|80 IRE||6978K (light gray)|
|100 IRE||6984K (white)|
We used Movie 1 mode as the basis for calibration. Results were then saved in User 1, which was used for all photo sessions unless otherwise noted. We refer to User 1 as Movie 1).
Pre-calibration, the color temperature measurements came out like this:
While the numbers across the range are exceptionally close, interestingly the H1080FD doesn’t have the usual R,G,B controls for doing a grayscale balance to 6500K. Mike tried some work arounds, including the CMS (individual color tuning controls), but to no avail.
As a result, our final measurements are still all up around 7000K. That means a touch too much blue, relative to red. This isn’t a big miss, and it’s very watchable, but not as accurate as an enthusiast would hope for.
Fortunately, they didn’t build this one for the video enthusiast, but for normal folks who just want a good, bright image, at an affordable price.
Vivitek H1080FD Basic Settings
|Settings for measurements (default values are in parenthesis):|
|Movie||Bright||Normal||User 1||User 2||User 3|
|Contrast||(10)||0||(4)||(10)-10||(4) -10||(0) -10|
|Brightness||(37)||(48)||(40)||(37) 53||(40) 53||(48) 53|
|Color Temp||(Normal)||(Lamp Native)||(Normal)||(Normal)||(Normal)||(Lamp Native)|
|Lamp Mode = Boost (High)|
In addition to our goal of calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. (As noted, this projector lacks those RGB gain and bias controls for a grayscale balance.) Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment.
Vivitek H1080FD Post Calibration Grayscale: User mode
|Color Temp over IRE Range (User 1, Post CMS):|
Post calibration, we ended up with the same color temperature as we started, due to the lack of the grayscale RGB controls. Still the picture looked pretty good! when watching the H1080FD.
As you can see, very tight range, just about 450K too cool. Fortunately, 450K is rather slight. As one calibrator once said to me (roughly): “When I calibrate a projector that starts out, inherently pretty good (such as off by 400 – 500K), and the customer sees the before/after, they see a small difference, and wonder why they paid a lot of money. Nevermind, that the picture does look better, even by their admission.”
Gamma: Mike recommends Gamma of 9 (the default), which measured a near perfect 2.23 (theoretical ideal is 2.2).
As mentioned above, the Vivitek H1080FD does not have the usual RGB settings. Instead, Mike came up with the best color he could for our “best” mode, using the CMS controls. This improved the overall color, even though it didn’t have any real impact on the measured color temperature:
|Hue||(-12)||(-22) 10||(-10)||(-8) 0||(20) 65||(-30) 70|
|Saturation||(105) 110||(94) 95||(98)||(86) 95||(98) 101||(90)|
|Gain||(100) 93||(104) 159||(104) 67||(104) 114||(106) 123||(100) 129|
Drop in thses settings, you should like the improvement.
Our brightest mode measurement worked out to 1777 lumens. You can up the contrast a bit to find a few more lumens, but that will cause some slight crushing of near whites (a small price to pay when you’ve got too much ambient light).
The brightest mode definitely has that heavy green push, that many projectors add to a bright mode, to get out more lumens. With the H1080FD, however, there’s no good way to adjust the brightest mode. I did open a couple of blinds, taking advantage of all the lumens. I would normally prefer to give up a couple hundred lumens for improved color, but when I dropped down to the next mode, giving up about 600 lumens was a big drop in brightness. In the Normal mode, however color is very good. So, Normal, when you can for sports/TV, and Bright when you need every last lumen.
