Phenomona of light (or semi-matte) anti-glare coatings?

I received a BenQ GW2450, and it had a weird white haziness to it in dark scenes. It's almost like a glittery quality, or something similar to IPS glow. And now that I think about it's the same effect I observed on the X-Star PLS monitor (with semi-matte AG coating).

My current monitors are both old TNs and have pretty aggressive AG coating (can't see any reflections even in a dim room with a black screen, but I could see some reflections on the GW2450). Neither of the TNs have these problems, and I find it weird that both AMVA and PLS panels can have visual quality problems that TNs don't.

Has anyone else noticed this effect with light or semi-matte AG coatings?

Oh yes, this is why avoid matte anything when it comes to displays.

And why if you only get glossy panels you never use them in anything other than a black room.

But it doesn't happen with aggressive coatings?

Did you not stop to think for once that perhaps I have complete control of the lighting in the room I game in?

What's it to you anyway? You afraid of the dark or something?

Like Skripka said, you don't want to use a glossy monitor in an area that has any kind of light, which is why semi-matte coatings are perfect as they are more versatile.

1.5 to 2 feet, eyes to monitor.

In any case the same effect doesn't happen with either of the monitors I have now at any range.

You do not need to sit in the dark with a glossy monitor. The problem with lighting is that people typically set up their "computer studio" with their desk against the wall like a bookshelf, which acts as a catcher's mitt for direct light pollution no matter what type of coating they have. Computers have often been seen as something to stuff away somewhere as opposed to how some people set up a nice tv "theatre" specifically for lighting, seating, and surround audio for example, or how people set up a photo studio, etc.

I set my corner desk away from the corner, taking over the corner almost like a cubicle or command deck type of thing. The room itself has plenty of lighting from floor lamps and a window , but none of them are above or in front of the monitor faces and desk. I even have a small lamp at each end of my long desk, in line with/adjacent to my monitors, but they aren't in front of them where they would have an angle of reflection.

Direct light pollutes any monitor, pollutes the monitor and color space no matter what coating.


Variable lighting condition environments completely alter the way our eyes and brains perceive brightness, contrast and saturation - so if you don't maintain the same lighting conditions your settings are completely off when the room lighting changes. I keep lamps so that the daylight window lighting levels are maintained at night so that there is no major lighting level fluctuation. In my living room, I keep 3 sets of settings on my TV for different lighting conditions/times of day for the same reason.
Even hardware monitor calibration is usually done right up against the screen in a dark room. It is a good baseline but once you change the lighting and use it in your actual viewing environment, the way your eyes and brain see that calibrated state is off from what you calibrated so you really should tweak it further to suit the way your eyes see it in that lighting environment. Any direct light hitting the panel also pollutes the color space as I stated. Then if you vary the lighting conditions in the room, your perceived settings fluctuate greatly (most notably, any brighter in the room yields paler screen and poor contrast, darker room yields brighter and more saturated, ..i.e. can be too much brightness and saturation).

This kind of picture floats around the forums , showing different AG coating level "frost" coatings under a microscope.



This is a 3-frame gif a user made representation of ag "frost" coating vs non.

I have not seen this artifact you talk about in semi-glossy (frost coating) screens, but i dont own one. What i can say is that semi-glossy gives a picture that is alot cleaner/ clearer than a standard matte screen. The gif above is very good represantation of what i see when comparing glossy to matte. Matte screens gives a dirty and less vibrant picture. Dont believe the naysayers on this forum, they are simply in denial or dont know what they are talking about.
