The Dell u3415w is notorious for IPS glow, i have owned one myself. Was only usable during the day. Had serious issues with slow pixel transition in the darker spectrum. Look it up on tftcentral. Otherwise gorgeous monitor.
ACER PREDATOR Z35, Pros: pretty darn fast overall for an ultrawide, Cons: Black/dark pixels takes longer to transition which can lead to undesired motion blur like effect. To what extent i dont know, im purely going on the reviews of the VA panel that i have read.
The sammy i know little about, but i would research the va panel before getting it.
The thing is with ultrawides from LG, that the price doesnt not dictate if you are going to have backlight bleed or IPS glow. Example would be my 230 pound 29um57 which was perfect in both catagories. What you want to look for is an 8 model(from 2016, um68, uc88 and so on) or if that is not possible a 7 model (from 2015, um57,um67 and so on). The 8 series has, according to LG representative here, been improve in these areas. I myself am looking forward to see how well this is when i get my 34um68.
Well, had some good news from the retailer I’m going to be using. They’re happy to exchange the monitor if ANYTHING (their words, in bold and capital letters) goes wrong with the monitor. Pixel-perfect guarantee or something. I specifically asked about the BLB and they’re happy to exchange it too. The only issue I foresee is what they class as ‘normal’ BLB and what I class as acceptable. They’re not a giant e-tailor like OCUK so I expect some push back as they can’t keep selling at a loss if I keep returning monitors. Usually I’m very easy going when it comes to monitors, but then again, I’ve not ever looked at spending a grand on a monitor so my expectations are high.
Honestly still none the wiser as to which direction I’m going to go. Gotta love expensive hardware upgrade time and the decisions and agonising that comes along with it . Especially a crapshoot lottery like buying a monitor.
