TN vs IPS - IPS glow sucks and I hate the internet!
Posted: 10 Sep 2025, 09:15
So, I recently bought a new monitor (Gigabyte M27UA) and I'm very disappointed with the IPS glow.
Here's the IPS Gigabyte: Compare that to my old Iiyama TN display from a similar angle: Notice how the contrast and details in the dark areas are completely gone on the IPS display. The dark areas at the bottom left are just a blob of gray. Even the rest of the screen has this ugly foggy look, as if there was a white filter on top of it.
Here's another IPS monitor, an older 60Hz LG: Similar problem. Dark areas become blobs of gray. Although in person it's not as bad as the Gigabyte. The Gigabyte is bad even if you look at it straight on from a regular distance, with noticeable IPS glow in the corners.
I wouldn't be so mad if this problem was mentioned and properly tested by people who make reviews and the various enthusiast communities, but it usually isn't!
Monitors Unboxed, for example, compared different panel types (IPS vs TN vs VA vs OLED ... I can't post links, but you can find it easily). He repeats the usual mantra of how great the viewing angles are on IPS compared to TN, but does he mention IPS glow as a downside? Nope, not even once. I don't get it. Many people in the comments pointed that out as well.
Rtings also don't test the monitors thoroughly as far as IPS glow is concerned. Apparently they take pictures for black uniformity from around 4 feet (1.2m), which is significantly farther away than most people use their monitor.
The only one who I've seen go a bit more in depth is "PC monitors" on Youtube. He does show IPS glow and some other problems that other reviews ignore, even if only briefly.
I know that TN panels have problems too. The colors and gamma shift a lot at different angles. That's a major problem in some cases.
But claiming that IPS is so much better at viewing angles as if it's some absolute truth is highly misleading. IPS is very flawed in terms of viewing angles as well and I think that in some situations people would prefer the color shifting of TN over the loss of detail and contrast of IPS. Maybe that's why pro e-sports players use TN monitors, besides the slightly faster speed.
Also, subjectively, often when I look at an IPS display it's like I'm looking at the picture through a filter (polarizer?) and it can be slightly nauseating. Whereas TN has a more raw/direct/sharp look. Does anyone feel the same?
Anyway, what annoys me is that because of the "IPS is so much better" narrative, TN monitors are now almost impossible to find. They don't make them anymore, except for those expensive 1080p e-sports models. That, plus the fact that a lot of IPS monitors just suck and it's hard to filter out the better ones, because the reviews are so lacking in detail.
