Then why do reviews I see say that the AX100U accepts 1080p/24 and 1080p/60? Does it accept these resolutions and downconvert them to 720p? If so that is very misleading and it isn't made clear to the buyer that that is what the projector does
This is standard industry terminology. If you can think of a better way to say it, then please suggest it, but ALL manufacturers, of ALL displays tend to list the accepted resolution formats for their displays.
Because video comes in 6 fairly standard formats in the USA including 480i, 480p, 720p, 1080i, 1080p/24, and 1080p60 it is important to know that your display is capable of at least displaying those signals if they are fed to your projector, plasma, LCD, or other display device. Even moreso, computer resolutions have dozens of different versions, and if you want to connect a PC then it is very helpful to know those resolutions that are accepted.
But - as is the case with all digital displays including LCD, DLP, plasma, LCoS, etc. in flat panels, rear projection, and front projection - there is only ONE resolution that matters: The display's native resolution.
FYI: I believe Optoma (or InFocus) has a 854x480 projector that handles resolutions all the way up to 1080p.
It's kind of like only speaking English but understanding five other languages. In the end, you still have to convert them to English if you want to speak.
