IPS Glow VS TN Back Light

[chenw]

Hey all,

I am not entire sure how exactly IPS (not just LG's IPS, but also AUO's AHVA, Samsung's PLS, etc) works, but there is something I would like to know about IPS glow.

Why is it that IPS glow always appear to glow 'on top' of the image, where as TN's back light usually doesn't? Usually if there is some colour in the corners, if it is not too dark, it will cover TN's black light bleed, but for some reason IPS glow seems to always on top of the image, IE unless the image in question is quite bright, IPS glow will always be visible.

Just curious. I had thought that BL3201PT's IPS type panel would give me a better viewing experience for moderately bright content, but I actually found it worse, which is both very annoying, distracting, and rather disappointing, especially since Swift is a gaming monitor, and I am having better time looking at movies on it than the IPS panel...

For the record, on a fully dark image, the two monitors look very similar, but the glow always seem to be on top of the image...

Thanks!

There is no reason for the glow to be there, it's just poor manufacturing, not enough LED's, poor uniformity, it's a recipe for disaster. I'm still scrathing my head everytime someone says buy an IPS if you're doing professional work, even though VA beat IPS today. I find that interesting. In laymans', VA panels are using a more effective solution to block the backlight. Since this is about TN vs IPS, my bias for VA can stay on hold for now. Despite all being a form of LCD's, they are all three very different from eachother, except that all use either back or edge LED's, latter produces worse uniformity. IPS monitors are thin, you know they are using LED's on the edge, which makes it even worse. The manufacturers claim it has super accurate colors, and whatnot, but in reality, it's horrible. That's LCD lab testing for you. If you look closely, you can tell that if IPS were using backlights rather than edgelights, the problem would almost go away. But manufacturers are cutting every corner they can, meanwhile increasing the price of the products. It's a combination of poor manufacturing, and cutting corners/cost. They can easily produce an IPS display with no bleed or glow, this isn't possible as long as edgelight monitors dominate the market. On a brighter note, buy a good VA, and never go back.




All the best!

I initially considered VA (BDM4065UC in fact), but I was talked out of it because that panel was slightly below sRGB coverage and VA panels suffered from horizontal shift. and add to that the fact that it is PWM, it was the little things that added up and I ended up getting BL3201PT instead, because the other VA options I had apart from the 4065 are all 1440p or below, which I was extremely reluctant to get (it was either 4k or 1080p, 1440p wasn't going to give me more gaming options).

It's unfortunate, the colours and viewing angles are very good on the BL3201PT, but the glow is borderline acceptable, to the point where I would have considered returning it if I was able to. I was just curious as to why it's ALWAYS on the edges, and why it's ALWAYS above the image. The glow on the 3201 is not even that strong, but because it's always on the top, it made it really annoying for dark content.

Yes, IPS glow can be frustrating. You may want to consider this one, incased you accidentally missed it, or never looked it up: BenQ BL3200PT

I saw that one yes, but 1440p was never within consideration, I was going for either 4k or 1080p, not 1440p, since I already have 1440p.

I am not that disappointed in my monitor, to be honest, the larger screen and higher resolution has its perks, it's just the perk I was most hyped about turns out to be a let down...

I always were curious if IPS glow was just shoddy QC (which I thought was unlikely, it can't be all that shoddy) or if IPS has something inherently that makes it glow like that.

The thing is. People that make a post about not liking glow/bleed, and asking for options, should just pick up a VA, be it UHD or WQHD. There is no other workaround, as far as I'm concerned. I don't have anything else to add to this topic, sorry.



All the best!
