Help with replacing Sony Trinitron G520 anti-glare film

dimes and nickles · Oct 14, 2013

Hi, I recently got a Sony Trinitron G520 CRT monitor that I really like about a year ago off craigslist for 10 dollars, but the anti-glare film is beginning to get an oily, speckled appearance right in the center of the monitor. The monitor is pretty old by monitor standards, having come out in 2002 I think, but the picture quality is just great and Im definitely not inclined to spend hundreds of dollars on a new LCD/LED that I doesnt have the quality that this monitor does.

Im looking to strip and replace the film on the monitor glass, but dont know what exactly what film I need to get. I dont have the original documentation, and even then I doubt it would have given film specifics. I see online that there are a lot of different films you can buy to place on monitors, thus the confusion about which one I should get.

From what Ive read I need a film that reduces brightness as well as provides anti-glare, which is what Im having trouble finding. I also dont know how much anti-glare I need; I want to preserve the picture quality as much as I can, and am reading that increasing the anti-glare means increasing the pixilation/noise in the image.

Any help would be appreciated in this matter.

Thanks.

Such monitors should have controls that reduce the brightness. See what it looks like after stripping off the old coating.
I think there are some protective antiglare screens that you can apply to the monitor. They just clip on over the tube.

I had a fine IBM CRT monitor. I added a lcd and the difference in image quality side by side was so stunning that I had to replace the crt.
As a plus, you do not need such a strong graphics card with a lcd monitor. A crt needs a 85hz refresh rate to keep from shimmering. That is hard to do if you are gaming.

The monitor does have brightness control, but Im worried about stripping the film without already having the right film to put on it. I already keep the monitor at 25% brightness, with the "professional" setting, which makes it darker than standard, so really the brightness level is below 25%. Sensitive eyes. I rarely raise it over that 25% level.

I had the opposite experience from you, I guess. Last summer in 2012, I bought a 300 dollar LCD, as my old CRT (not this one) was having trouble turning on. I think it was the flyback transformer from what I can deduce with my limited knowledge of how CRTs work. But when I got it home and turned it on... I couldnt stand it. I think it was a Sony LCD... not a no-name brand or anything. The old CRT had such better image quality, from my perspective.

The only thing that I saw that could compare to the old CRT was thousands of dollar plasma TVs, which admittedly had superb pictures. But I simply cannot afford that in anyway... hence the buying of another CRT off craigslist for 10 bucks. Best image quality Ive ever had personally (original price of this monitor was 900 dollars, so Id expect it to be good).

It seems Im looking for a "neutral density filter" film that I could place on the monitor, perhaps with anti-glare properties to it. I found one place that makes films for monitors, Photodon, but they do not have neutral density films Ive found after talking to their sales people.

Im just worried about stripping the film off without actually knowing how much brightness the current film is actually reducing, which unless someone with a similar monitor can say from experience, Ill probably never know until its stripped. But if the monitor is then unbearable to look at, and I have no film to put over it, Im in a worse situation than the oily-esque specks are creating now.
