The guinea pig, http://www.geeks.com/details.asp?invtid=FPD1830-1B:



Wet shop towels. Use distilled water with a spray bottle. Towels should be greater than damp, but not dripping wet. Test for matte film removal was for 2, 4 and 6 hour intervals. At 2 hours, the film was still too stiff for proper removal. At 4 hours, it was much more pliable but not where I would want it for a quality removal. Previous users have noted around six hours for film removal. I would concur, 5-6 hours will work well. Although the film took some pressure to remove at 4 hours, there was no trace of adhesive left behind. Roller was used to make sure shop towels have great surface contact and to remove any trapped air under the towels.



Matte film scored and removed from the majority of the panel for comparison.



In the below image, the monitor is on with a black background. The quality of the blacks and area with and without the film are apparent. The far corners have the polarizer removed. The polarizer is adhered to the LCD glass with very strong adhesive! Even using a 400 F heat gun it was extremely hard to remove and usually came up in slivers. Any damage to the polarizer will ruin the monitor. Without both intact layers of the polarizer, you will get no image (hence the white area of the corners).



Polarized versus non. I wish we could get the great whites of the non-polarized area. But that would render LCD technology inert.

Surprisingly, this particular model doesn't even have that strong of a matte film. Surely not as bad as those found on a lot of LG's IPS displays. You can actually see through this film fairly well. Others I have seen are more difficult to see through.

Now I have heard a lot of reports of users in the past damaging this polarization layer by "touching it" or cleaning it in some way. I was unable to reproduce this as can be shown in this video:

I put a great amount of pressure while going over the edge of the matte and onto the polarizer. I could not get any damage to either surface working it very hard. This polarizer layer is like a sheet of plastic, has a gloss feel to it and is very durable. Not sure if those in the past that have so-called damaged their polarizer was of a different material/design, or the damage in fact was not the polarizer but another layer or aspect of the display.

Below is a video showing the dramatic image quality difference with and without the matte film. I think it speaks for itself why I prefer glossy displays. Perceived blacks, color, and contrast are all improved. The colors "pop" and are more vibrant with gloss and the display no longer has a washed-out, dull appearance. You also remove the annoying "sparkle" of whites you get with matte film. At the end of the clip you can see the corner of the polarizer layer and it's rotation to block light.


Next up on the chopping block is the 144 Hz 1ms Asus VG248QE! World's fastest LCD (along with sister BenQ XL2411T) combined with a dramatic image quality improvement inbound...

A great comparison there Vega. A colleague of mine 'semi-stripped' a U2311H in this way and the comparison was stark. In your example the matte film is much lighter than that used on the U2311H and you can still see differences (even in images of the monitor). It was the U2311H semi-strip comparison and some experience with various monitors of different haze value that drove me to write an article on matte vs glossy displays. If people step back and think why a matte surface is able to reduce glare, it's because it diffuses ambient light rather than reflecting it. It does the same to the monitor's own light, of course.

By next weekend (I have a four day off).

Great article. These points sum it up nicely from your article:

Direct light emission enhances contrast and image vibrancy
'Cleaner' image without hazing or graininess

If you have any light control whatsoever, I couldn't ever imagine preferring a matte screen. I guess I should also have used the term anti-glare film removal, not AR.

I believe the reports of people damaging the polarizing layer was due to them cleaning with a wet cloth directly after usage. My feeling is that the CCFL backlights in those monitors (ie the Dell Ultrasharp ones that people claim to have ruined) causes them to heat up far hotter than what you would experience in a smaller monitor like you have tested with, i.e. heat and water together are the culprits.

Of course the other potential reasons you mentioned likely also play a part in the fact that you couldn't damage yours.

Doesn't it seem like there would be a huge market for an inexpensive, super fast monitor like the Asus VG248QE if it just had a glossy friggin screen? I mean, another company, using the same panel, and having it have a glossy screen instead? Assume you made a bulk purchase order of 200,000 panels form the OEM and had it special ordered to glossy instead of matte to lower the costs and not make it so you are yourself removing matte/applying glossy. Is this way off base? Brand it for gamers, market it to gamers, advertise it as pro-gamers choice, give it to competitive gamers with brand appeal, push it on newegg/amazon at a price point under $300. WHAT THE HELL.

Samsung has some super fast glossy monitors.

CallsignVega are you going to leave the screen like that or did you add another glossy layer after?
I'll admit that my search was short but I haven't found a glossy overlay to use once the matte finish is removed. Then there is the whole process of properly affixing the new overlay.

This was just a test monitor. Thea real test/od will be with the Asus QE.

Yes, it is quite a thick, strong layer. Through some research I've found out that AR films have ultraviolet radiation protection built in. This is of course to protect your eyes just like sunglasses outside. Now I am not sure once you remove the film if having an exposed polarizer would remove/reduce this protection. If the Asus QE panel has a durable/robust polarizer, I still think I'd put the gloss film on for the protection it provides as explicitly stated by the OEM. Any risk to the eyes is certainly nothing I'd ever want to even question in the slightest. Maybe PCM can chime in with some input. The thing is that with ultraviolet radiation, you won't be able to tell or "feel" that anything is wrong and damage can take years. I would err on the side of caution, but that is just me.

I would not put any layer on that is not designed for displays, their special optical properties and protection as stated above. You could always try though.

Nice investigative work Vega.

I'm pretty confident that the spidering we've seen with some of these displays is caused by the towels being over saturated with liquid and diffusing between layers of the display. Essentially the layers suck it up like a towel or the straw trick if you've seen that. There is a scientific name for it, but I can't think of it right now (osmosis?).

If the layer is like plexiglass then it'd be very hard to damage with a heat difference. It would have to get super hot... like hot enough to warp the plastic in order to cause it. Although it's definitely something worth looking into.

Some good questions:

Is the spidering damage caused by heat? Have you left the monitor on for like 12 hours and then tried wiping it down with a cold rag?

Another question, how resistant is the polarizer to scratching? I watched the video, but have you tried using a paper towel for instance?

Obviously I don't want to absorb UV constantly through something I look at 10 hours a day, so if there are radiation risks it'd definitely be worth looking into.
