The HD91 remote control is a nice one. I find it’s blue LED blacklights to be attractive, but also a bit too bright for a really dark room. The buttons are small but there’s some spacing, and the organization is good. A number of buttons are essentially shortcuts to some submenus, as is typical.
Let’s run through the functionality from the top.
On the top right is the Power button. Press once. Unlike most projectors the HD91 has a separate power off button right below it. Straight across on the left is Brightness, and below that Contrast, then CMS for the color management system access, and the LED Brightness which also controls Dynamic Black. Below the power buttons is the Gamma menu, HDMI Link for controlling other HDMI devices, and Advanced which takes you to the Advanced menu, which provides access to other sub-menus including Pure Engine and LED Brightness.
Next comes the navigation, four arrow keys in a round formation, with the usual Enter button in the center. Below to the left is a small Menu button, and on the right, the Mode button for quick access to change the color mode.
The next four buttons offer different aspect ratios. You don’t often see that any more, simply because we don’t often need to manually change. That’s at least true for folks sticking to Blu-ray and not DVD players where the need was greater.
Next on the left is Pure – takes you to the Pure Engine menu with Ultra Detail, Pure Color and Pure Motion submenus. Across on the right is the 2D/3D button.
That only leaves the six buttons down near the bottom five of them are your choice of sources, and the sixth – upper right is re-sync should you need it with an analog computer signal.
I like that Optoma offers clusters, then spaces, and varies the button sizes as well, to make it really easy to remember the locations of all the ones you are most likely to use often.
If there's one complaint, the pretty blue LED lighting is very bright. A bit too bright in a dark room. When you are trying to adjust color, it can be almost blinding. OK, I'm being a bit picky. Hold the remote upside down if that's a problem for you.
