I looked the manual up online and it lists 1080@50 and 1080@60 as available for HDMI so that clears that up at least. Good to know the timings as well.
I was comparing the HD131Xe to the W1070 (as I've seen a LOT of people do) and technically it seems the W1070 has a few advantages but from my research it has a lot of quality issues.
The HD131Xe seems to suffer from a corner focus issue and possibly some geometry issues (has Clark17 been the only one to report it so far?). However the W1070 seems to suffer from brightness uniformity issues (left to right), focus issues (some W1070s are blurry unless pushed to max zoom), and dust getting into the lense (although the HD131Xe may also get that eventually to be fair, just no reports yet due to it being newer).
The difference is that it seem Optoma is willing to fix their reported issues whereas Benq has been saying their reported problems are "within spec" and refusing to resolve them.
So, bottom line. Unless Benq starts fixing the reported issues with the W1070 I see no reason anyone should even consider it, even if it is superior at certain things.
When it comes down to it the Benq is really only slightly better at color (thanks to the RGBRGB wheel vs the RGBCYW), although it's much better at RBE (thanks to the 6x effective wheel vs the 2x effective wheel). Whereas the HD131Xe has better calibrated lumens and contrast ratio, as well as having faster latency for gaming.
For me in a living room (4 windows with blinds/curtains, large open room connecting to a couple other rooms, white ceiling, shiny wood floors, etc.) I figure I need all the lumens/contrast I can get. It'd be nice if the color wheel was faster to eliminate RBE but I guess we can't have everything @ this price point lol.
Luckily I won't be buying for a few more months and maybe everything will be ironed out by then (or new models released).
