CRTs at high refresh rates

Recently, I bought a Gateway VX1120 CRT monitor, with the intention of running it at a low res with a high refresh rate. The monitor has a max default setting of 2048x1536 @ 80hz, so I would assume that it should be able to do well over 120hz at 640x480, but the max refresh rate that I can set in windows is 85hz, which it can do at 1600x1200. Currently, I'm using this as a second monitor with a 1650x1080 LCD, though I don't think that should be a problem at all, given how it can already run at a different resolution then the LCD (60hz).

I've tried installing RefreshLock, but that doesn't display other other refresh rates either.

Can someone who uses/used a CRT explain this to me?

Apparently you need drivers from Gateway.

I downloaded and installed the drivers from Gateway, but when I followed the instructions on how to get Windows to recognize them, windows returned that the current drivers (Plug 'n' play) were the most current, and didn't use them. If there's a way to circumvent windows and just use the drivers, that would probably work.

i had to use Catalyst Control Center to get my CRT to go down to 640x480
if youre using an AMD card then you can try that.

I'm on a GTX 560 ti, probably should have said that in the OP.

Also, if I use the Nvidia Control Panel, the same default refresh rates and resolutions come up.

Would setting a refresh rate/resolution combination which requires too much bandwidth physically damage the monitor, or simply not work?

Edit: Used CRU to add two standard resolutions, then used refreshlock to set to those refresh rates, I noticed no difference, and when I used refreshlock to set the refresh rate to 50hz I still could not notice a difference, pointing towards the monitor simply not changing refresh rates at all.

Edit 2: Used CRU to make a "Detailed resolution", I'm reasonably certain that it works, running in 720x480 @ 140hz, thanks atmo.

nvidia allows you to set your own custom resolutions and timings, I don't know why you need extra software to get it to work?

I was able to set all that in my nvidia control panel. If your monitor has a pretty decent tube you can attempt to run a high refresh rate and high resolution. I'm currently able to get 1440x900@120hz here. Gl man

I'm assuming the reason why I needed to use 3rd party software was that this monitor had no default settings which involved a high refresh rate, all the 3rd party software did is write to the driver that a given resolution/refresh rate was "safe", which made the option come up in windows, nvidia control panel, etc. I've managed to go up to 160hz @720x480, after using a TFT panel with 20ms input lag, it's wonderful.

nvidia control panel has options for custom resolutions though, you don't need 3rd party software at all

What would happen if you force a monitor outside on its ability, like pushing a 85Hz to 120hz? I have one I don't care about and I would try it, but I don't want to break anything else or start a fire.

monitor just turns off and goes "can't display"
it's not as dangerous as you think.

This is exactly what you can do with nvidia by default.....

Oh, I entirely missed that menu. Well, thanks for pointing that out, should be helpful.

dunno if anyone else has this problem

every time i shut down my computer and power it back up, my crt goes back a default 'plug-n-play' in my monitor settings and i lose all my osd settings and my resolution settings.

it fixes itself when i go to screen resolution and detect it but it's kinda annoying having to do that every time i play tf2

viewsonic p95+ is my monitor
