The HD23 remote control is well designed in terms of layout. In addition, it's range seems very good, easily past 20 feet, which is better than some others. The actual IR beam seems narrow, so it is a bit more critical than most to point it in the right direction - toward the IR sensor on the projector, directly, or with a bounce off your wall or screen.
As to the layout itself: Power On and Off have separate buttons on the top row.
Next come four aspect ratio buttons, in two rows, but the top of those two has a center button which let's you change lamp brightness.
Two rows of three have: Brightness, (preset) Mode, Contrast, on the first of those two. The second row has both Edge Masking, and the Overscan alternative. The center button is a Source Lock. The HD23 can search through all the inputs automatically, looking for live ones, or with Source locked, it will stay on the one you set it for.
That brings us to the Navigation area. Four arrow keys in a roundish shape, with a center locate Enter button. Menu is below to the left.
That leaves only the five bottom buttons which control sources. There's two HDMIs Computer (or a second component), Component video and standard composite video. That' all she's got!
This remote control is extremely similar to past Optoma remotes. I have the same old complaint. The Optoma remote is backlit with bright blue LED light. It is almost blinding in a dark room. Way too bright. If I want to tweak colors I have to hold the remote where I can't see the blue or I can't see the finer points of the screen.
OK, it's great going with blue LED lights for backlighting, but please, pick a dimmer LED bulb or cut down on it's brightness another way. One third the brightness is probably more than bright enough.
All considered, a perfectly fine remote, other than being too bright. Button feel is reasonably good. Learn where the buttons are, and the LED light brightness can be dealt with. On the "bright side" when the room is fully darkened, the remote can double as a nice (blue) flashlight for reading Blu-ray disc boxes, finding your snacks, and hunting for that black Sony PS3 remote (that I can never find in the dark), etc. I guess there is a silver (blue?) lining to many issues.
