Sorry, haven't heard of any other brands - but I'd assume that all the big computer companies will soon catch up with BR technology, right?
I'm pretty sure, come to think of it - that Apple have HD monitors.
Also - Dell makes them, but I haven't heard great reviews about their products. Plus, Macs tend to handle multimedia applications much better than PCs in my experience. I worked with a PC and Mac on the same project (using Adobe InDesign, Dreamwever, Flash and some other programs) and the Mac was much more comfortable and efficient to use.
Is this the sort of thing you're after?
