MSI MAG271CQR - brief red ghosting when looking around screen while MBR is on
Posted: 25 Jan 2020, 10:46
Hi blur busters,
I've experienced this issue while MBR is enabled on my recently bought MSI MAG271CQR. When MBR is switched on, then whenever I dart my eyes around the screen, there'll be a very brief bright red ghosting afterimage trailing behind objects. This is most noticable on white objects against a dark background. Needless to say, this is very jarring, because the things shown on screen may not be red by themselves, but they generate momentary red shadows.
This is not a one-off, I've actually also experienced the same on a monitor sold by a local reseller brand from my country (https://prismplus.sg/products/prism-f270i-pro - they probably rebrand OEM monitors sourced from China). I ended up returning that one for this same reason.
Before that, I was using a BenQ XL2411, and it did not exhibit this problem. Maybe the most obvious difference amongst these 3 monitors can be best described by comparing how they appear on https://www.testufo.com/blurtrail (default settings) when MBR is switched on, and when eye-tracking the moving white line.
BenQ XL2411 (TN, 1080p, 144Hz): a clear but faint 2nd white line appears a few pixels before the 1st white line. no other colors besides black and white are observed (this is as good as it gets)
MSI MAG271CQR (VA, 1440p, 144Hz): The line looks more like its ~6px long instead of 1px. It looks like a cyan-ish white, while the black in front and behind it is more like a reddish black. (There's also a 2nd faint cyan-ish line, FWIW)
Prism+ F270i Pro (local reseller brand, IPS, 1440p, 144Hz): Like the MAC271CQR, but even more pronounced. I recall feeling as if I was looking at 3~4 cyan and red (2 each) ~6px rectangles.
I've resigned to disabling MBR on my MAG271CQR for now, as I don't want to see a rainbow flash everytime I move my eyes.The XL2411 seems to get things right, so I wonder, what's the reason this "color separation" happens on the other 2 monitors? Is this something that is common with many implementations of MBR? Is there a name for this effect?
