CRT not displaying 120hz properly after new video card.

post #1 of 9
Thread Starter 
Hello all,

I upgraded my video card recently and my crt is not properly centered anymore no matter how much I try to play with the settings. The weird thing is that it works perfectly at 110hz but at 120hz the left side of the screen is slightly cut off. (no matter how much i play with the settings it is impossible to get it perfect)

Any idea what this can be? i upgraded from an HD5870 to a GTX 570 and the problem didnt exist before this upgrade. The CRT is a p991 dell if that matters.

edit: i play at 800x600 so the resolution isnt an issue.

Wait,

You're gaming at 800x600 with a GTX570.... Why for the love of god did you upgrade? Either way, the issue probably remains with the drivers. I'd uninstall all your video drivers (including your old ATI ones) then run driver sweeper. Once you've done that, install the latest release from nvidia and give that a shot.

Seriously though, why did you upgrade, 800x600 wouldn't have stressed your 5870 let alone a GTX570.

You need a new screen ASAP to take advantage of that card.

Comps

Why I possibly thought I could ask a CRT question without explaining myself first I have no idea.

I own a alienware aw2310. Games that I play seriously I play in 800x600 on a crt. Games that I play for fun get played on the LCD.

I will try fix but it seems like a long shot. Thanks.

Your attitude sucks, simple as.

Anyways...

I cleaned the drivers, reinstalled, etc.. this did not work at all. I suppose I can just play at 110hz for now on but I wish I understood why it did that suddenly.

Anyone have any other ideas?

I presume that it did 120 Hz with no problem on the old video card, but not the GTX570. A refresh rate of 120 Hz is the maximum for that monitor, but it's strange that it would do it on one card and not the other one.

It's probably some difference with the way that the GTX570 operates as compared to the HD5870, but I have no idea exactly what it would be to cause an issue like this.

It's been sometime since I sold my gtx570. I remember having the same problems with a CRT @ 120hz. Creating a custom resolution fixed the problem (even if 120hz exists as a default). You need to use a specific timing, GTF iirc (see: http://www.nvidia.com/object/advanced_timings).

Yeah that's what I did. It was ruining my eyes for some reason though. Maybe it was in my head. I ditched the CRT though and am going to try to get used to my LCD for gaming. Not a fan of 16:9 but I want to get used to it.
