Yes, NEC over the 1655 for me too. I've only had one Benq 1655, but about 7 or 8 NEC's, from the 2510A and beyond. The BenQ I got is very picky with media, and I've tried all the firmwares. It sits on my desk now, not sure what to do with it, as I don't want to trash it, but probably can't even sell it for much to make it worth getting off my ass and shipping it.
The NEC's I've had, all of them, has never ever met media it did not like, and I've never even flashed the firmware on them, bone stock with shipping firmware.
Another note, because of my problems with my benq, I went perusing all the usual sites for firmwares, and everyone is complaining about the newer firmware writing strategies sucking for the Benq, and speculation this will continue ever since LiteOn purchased them or whatever.
I'm sticking with NEC until I get burnt.
