I have a GTX1080Ti currently paired to a 1080p 24" monitor. This seems a bit of a waste, so was thinking of one of the myriad 27" IPS G-Sync monitors that are currently available. Such as the Acer Predator XB271HU, or the ASUS PG279Q. I've already asked a similar question over at OCUK - but there are a couple of details I'm not sure I can ask there, because it's retailer backed. I'm concerned about stories of dead pixels or backlight bleed. OCUK themselves have a guarantee on the ASUS that there will be no dead pixels (but don't mention bleed) - but it is over £150 more than the all but identical Acer (which has no such guarantee). Presumably the price difference reflects that guarantee? But if I order over the internet, can't I return within 14 days for a full refund anyway? Do they actually have the option to not replace if I'm not happy with what I receive, regardless of their own wording? This will be the most I've paid for a monitor by a factor of about 4, so I'll be crushed if I get something substandard in return for my money. Alternatively, is there somewhere else reputable selling these monitors at a good price including a QC guarantee? Thanks in advance for any advice people can offer.
