The glow will still be there, but after using my 2795QHD for about a month now i really dont get hit with dark enough screens to ever be that bothered by the small amounts of glow. Other than that the Acer will also blow the Dell out of the water in picture quality with its panel and much lighter AG coating.
XB271 has good overdrive for an IPS
and only at 144Hz or lower. Compared to the Dell it can't compete in response time. The testufo.com's ghosting / pursuit camera test still blurs on my Acer and was almost perfect on the Dell. When ULMB is enabled there's little benefit to it on the Dell while on the Acer it makes the main image sharp while introducing ghosting after-images. In the full-screen moving photo test ULMB makes the Acer have almost doubled image shadow on the lower part of the panel while the Dell is mostly uniform. This is similar to old BenQ's strobe crosstalk.
I did run both at the same time in clone mode to compare and If you are sensitive to ghosting the Acer will be at a disadvantage (apart from the usual panel lottery of course
I chose the Acer since I seemed to have struck a golden panel and Dell's gamma problems, gamma/colour shifting and the terrible, terrible AG were getting on my nerves.
As a side note I actually found a use for the extreme overdrive setting on my Acer - Diablo III is so dark it's acceptable to improve the response time while making the artefacts almost invisible.
