LE: what is the seating distance?
If it's 12 or 13' that is too far to see the improvement the 4K resolution will bring. Feeding it a 4K HDR source will be better than a SDR source, and with 100" the WCG filter (which cuts 30-40% of brightness) might leave enough brightness.
Thanks again for the advice. I already own the W2700 by the way, just trying to make it work with my new room layout.
One thing I had forgotten during the room re-construction was that my W2700 seems to be out of spec at the wide end of it's zoom.
In the few minutes I had this morning, I pulled the projector forward so the lens is now 126" from the screen. The image at the widest setting is still much bigger than the 100" screen. I'll have to measure it properly tonight, but I'd estimate it's around 110".
The calculators I have used (BenQ's own, Projector Central and Projectorpoint) are all slightly different, but all agree that I should be able to go as low as 100". I appreciate that they are never 100% accurate but I'd expect the image to be a little bit different size rather than massively out.
Am I calculating this right? The longest throw on the W2700 is 1.47, meaning that the projector lens can be placed at 1.47x the image
width. A 16:9 screen with a 100" diagonal has an 87.16" width, so longest throw should be 87.16 x 1.47 = 128"
Seating is around 10' from the screen. The images I have tested it with certainly look great (although I can't see the whole screen!), but I've not compared 4K to 1080p properly.

The numbers are correct.
Longest distance for an 100" screen is 128.18"=10.69'
If the PJ is placed at 126" with no zoom that will be 98".
If it's with 100% zoom that will project a 128" diagonal image.
The closer a projector is to the screen the brighter it will be. This one is not particularly bright.
It's not the first time I've heard of this model's zoom not corresponding to specifications.
