I just did the mod on my Dell U2412M. It worked perfectly. I ran a trial on my Samsung P2250 first to practice. No problems here.

I soaked the Dell U2412M for a little less than 4 hours until the bottom right corner of the AG coating could be lifted without using force at all. Then I could smoothly roll off the coating in a bottom-right to upper-left-corner directed steady slow pull. A few times the coating was stuck and I had to wiggle a bit to get it moving again. This left som uneveness in the residual glue (thin lines), but these lines are only visible when the monitor is powered off and when the screen is viewed from the side with strong lights on it.

It was a succes I would say. The panel is sharper now. Colors haven't changed that much really, but I got rid of the annoying "greying" of the surface when light from the window or a lamp shines on the surface at an angle.

Nice post OP! :)

Bumping this because I want to try this on a TV.

Would anyone know if this method would be any different on a 65" TV?

Signed up here to share my results with this guide on my Asus VG248QE, it worked flawlessly. I was patient the let the towels saturate for about 10 hours, I really wanted this to work on my 2 month old monitor :eek:. Here's a few pictures I took during the process. The AG is like a brittle vinyl sticker, it decided to tear on me a few times but the pieces still came off with ease! Thanks for the guide!

Nice work! Looks really good. I successfully did that with my Qnix qx2710, and tried to do that even with my Eizo fg2421. On the Eizo I left the towels on for 6 hours but the ag didn't peel at all after that period of time. Would going for 10 hours make a difference? Might give it another try.

Would this work on the Dell 2415q?

It would be nice to be able to actually use the 4k display.

Thanks

The only way this technique would not work is if the monitor had a spray on AG coating and not a film. I have not found one spray on coating yet. It just seems way to time consuming to come up with a new way of putting on a coating vs industry standard of a water permeable film.

How would this work on a UP3214Q?

For the last year, I have this beautiful 4k IPS 32inch monitor and the AG is driving me nuts. I feel like I am looking through a dirty windshield of a car.....I would pay money to get this thing done if the person was in LA.

Sorry for the thread necro, but I had to stop by and say thanks for this awesome guide! It worked like a charm.

I recently acquired an LG 27EA33 for basically free, the only problem was it had significant scratches on the display. I was pretty certain that they were limited to the AG layer and so the plan was to have a go at removing it (and since the monitor was basically free I was okay with the idea of gambling its potential sacrifice to the silicon gods).

So following this guide I soaked the screen from five hours, and the AG peeled right off leaving no trace of any glue or residue! I now have a beautiful glossy scratch free monitor and couldn't be happier! A day in and so far no problems (fingers crossed). I am hoping that if I take great care/caution when I clean it and move it that it will have a long, happy, and glossy life. :D Thanks again for the guide!

Thanks for taking the time to post your positive experience! I typed this response whilst watching some ted talks on the very same monitor used to create this guide :)

Oh boy I really need to do this on my Dell S2716DGR.

Matte finish doesn't do it for me.

Would this work on a U2415? I scratched mine and it's driving me freaking nuts. This might be a solution.

I just did this on my U3011. Soaked for 5 hours and the film peeled right off. I have had this display for 4 years and was getting ready to unload it later this year anyway so I figured meh, what the hell? I had always dreamed of doing it to this monitor and since I already got my 'fair share' of use out of it, the worst case scenario is that I'd be out a few hundred bucks at this point. It ended up being time consuming but went smoothly with the exception of accidentally bending some of the ribbon pins when I was disassembling. I had to use a needle to re-seat the bent pins which was lots of fun. I feel the risk was worth it at this stage, and might well regret not doing it sooner. It really looks like a totally different display.

Something I've noticed is that only TN and PLS panels can have the AG removed without getting the graining issue. If you remove the AG on an IPS panel and try to clean the glue residue off (for some weird reason) the polarizer starts splitting and cracking like strands. I did 2 IPS panels and they both grained up and are ruined. Did 3 other monitors which were 2 TNs and a QNIX Samsung PLS and the polarizer was very durable, it did not grain no matter how hard I cleaned it while IPS panels started splitting and cracking after just barely touching it. My only theory on this is that IPS panels use a polarizer made out of a different material and requires a protective sheet unlike TN and PLS. Everyone who did AG removal on IPS panels got the graining issue, everyone that did AG removal on TN and PLS did NOT get the graining issue so It's not just limited to the specific monitors I did.

Anybody wants to tell if their screens have cracked after some time?

I have gotten the "graining" issue ONLY with IPS panels, never with TN or PLS, even after cleaning them aggressively. The IPS panels started graining after just barely touching it. QNIX with the Samsung PLS panels do very well with removing the AG, It peels right off after only 3 hours of soaking and does NOT have the graining issue. PLS also has better colors than TN and is on par with IPS.

OP's monitor is IPs but he hasn't reported any graining... has he?

He posted this on the first page "Screen is still fine, it developed a couple very small vertical grain lines in the middle of the screen that are completely invisible (and I really mean this, I've tried to look for them) while the screen is on. They do not have any kind of texture detectable when running a fingernail over them gently. I will take a few pictures with the screen on and post them in a little bit."

I think the reason why his graining isn't so bad is because he didn't clean the glue residue off. I clean all the glue off because dust will stick to it and cause smearing/smudging issues. I wouldn't want a monitor that I can't clean. The reason why IPS panels grain and TN and PLS don't is unknown. The only thing I can think of is the polarizer is made out of a different material that requires a protective sheet while the PLS and TN don't. This is very unfortunate because a $1000 IPS panel will grain but a cheap $100 TN panel won't.

If you want something to remove the AG on look for a QNIX with a PLS panel.

Finally tried removing the Benq bl3201pt bezel following this guide using plastic pry tools.
Spent an hour carefully prying and not getting anywhere and causing mintor damage before reading this thread.
I used as little force as possible struggling to get one edge to come off and then it cracked. Stupid.
Time to get a new screen.

Did you get grain lines when cleaning the glue residue off?

I never got that far. Removing the casing was just too difficult. I don't see how it's possible when it won't budge even with all my strength pulling it and hurting my hands yet the screen will crack if you so much as breathe on it heavily.

Do you happen to have pictures of it with your computer and screen on? I have the same monitor and I'm considering doing this.

Don't do it. IPS panels require a protective sheet or it will grain from just barely touching it. TN and PLS panels don't have this issue and the polarizer does NOT require a protective sheet. Read post #140.

Currently at the 4 month mark and the monitor is working 100% with the polarizer being exposed to the elements. Will upload pics later tonight.

EDIT: Yes, the vertical graining is present but barely noticeable, and only noticeable from very wide viewing angles and ONLY if you really try to fixate on the grain, Otherwise, the graining has in no way impacted my enjoyment form making the modification all these months later. This monitor became completely different once the coating was removed, like it all of a sudden became all "HD", and with it already being 4 years old and nearing the end of use for me, I figured what's to lose if I screw it up.

So far, no regrets... it actually breathed new life into it and extended its purpose on my desk for (hopefully) several more years. I often think back to the night that I took the risk and soaked this $1000 panel from 2013, and I always smile when I turn on this monitor and see it the way it was meant to be seen.

So disappointing to hear this doesn't work on IPS panels :(

I wanted to do this to my Dell U3415W.

I developed a wavy pattern on my moniter that I was hoping I could get rid of when taking the AG coating off.

After you remove the ag is there no protection on the screen from the outside is that why people mention being extra careful when cleaning after the mod?
