I don't know if LG CRT monitors are / may be related to Samsung CRT monitors or not. But if they are, all I can tell you is that I've read in Samsung CRT SM's that they use a software called "SoftJIG". It's essentially the equivalent of what WinDAS is for Trinitrons, but I never used it... and don't think I have a copy either(??) (Will check on that.) I did do some digging into that topic a long time ago, though, since I have a Samsung SyncMaster 955DF that's a little too bright (too much G2), though not terrible like a 21" Trinitron. Was going to mess with it, but then figured I could use the brighter monitor for online gaming, as I already have another 19" CRT that has pretty much perfect colors and brightness which I use for "cinematic effects" gaming.
If there is no software to adjust the G2, you can try to trace back (either in the SM or on the actual monitor PCB) where / to what chip the G2 gives feedback about its voltage value and try to "fool" that chip / circuit with some resistor dividers. Back before the guides for Sony WinDAS became popular online, I remember reading on quite a few places where people used this trick to lower the G2 on their Sony Trinitron CRT.

I have an 15” SVGA IBM monitor that is really blurry. Are you saying this is fixable by opening the monitors case and adjust something? I was about to chuck it in the bin.
Possibly.
It might just need a G1 (Focus) adjustment through the pot on the flyback transformer (some monitors have two Focus knobs... but that's usually the larger, more "modern" CRTs.) Or it might need a recap (rather involved job).
Whatever the case, advisable not to just "chuck it in the bin", if possible. If you don't care to fix it, you can always put it up on your local Craigslist (or equivalent site) as a "free, you pick up". That's how I got most of my CRTs back in the day when people were getting rid of them left and right. And that's also how I've given away a number of items before. So long as you're not too far out "in the middle of nowhere", this method usually works for getting rid of stuff.
