Vivitek H5080 Menus
Vivitek's menus work well, and look particularly good - very clean and professional appearing.
There are six main menus - Picture: Basic, Picture: Advanced, Display, System Setup: Basic, System Setup: Advanced, and Information
The Picture: Basic, starts off with Display mode that allows a choice of Movie, Bright, Normal. These three presets are pretty much "what you see, is what you get." Using them locks out virtually all controls. To make any adjustment you needinstead to select one of the three user modes (1,2,3).
As a result we used User 1 as "best mode", and User 2 as a "brightest mode". You can set each user mode to be based on the default settings for any of the three presets (Movie etc.).
The Picture Advanced, has control of Color Temp, gamma, the dynamic iris "DynamicBlack", the manual iris, and "Vivisettings" which includes the projectors creative frame interpolation.
There are two different settings for the dynamic iris, of which I mostly worked with Cinema 2.
The Setup menus cover all the things you would expect from projector orientation (ceiling/table/front/rear) to menu options, lamp power, auto off timers, 12 volt screen trigger controls and more.
Basically, the Vivitek H5080 menus have most of the usual goodies, and they're pretty logically laid out. Still, I like (logical or not) to have lamp power with the picture controls. More notable, perhaps is the Overscan feature. You can control the amount of overscan with the slider control, but the H5080 does not have the option to use cropping, instead (which would preserve 1:1 pixel mapping, but create a slightly smaller - but sharper - image).
If I had one other request, I would have liked to see at least 3 more user memory positions, especially since you can't tweak the standard three.
Vivitek H5080 Lens Shift
The H5080 has a decent amount of lens shift. It is set up unequally, which is always interesting to consider. I found the manual very confusing. Here's how it seems to work, first for shelf mounting. For shelf (or table) placement, it can be anywhere from 10% of a screen height (4.9 inches) below the bottom of the screen, to 30% (14.9 inches) below the top of the screen surface. A 100" diagonal screen is about 49 inches high. That's measured from center of the lens.
For ceiling mounting, where you often prefer the projector to be above the screen, the H5080, (inverted) in a ceiling mount can be from 10% (4.9 inches) above the top of the screen surface, down to 30% (14.9 inches) above the bottom.
I think that by doing it this way, Vivitek has pretty much gotten the best combination of functionality relative to the amount of total lens shift they were comfortable providing in this design. The fact that there are other lens options may have encouraged this final setup, as well.
