Hi i recently got a new monitor.
Its the alienware optx aw2310(http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&cs=19&sku=320-8846)
It seems that 120Hz is only available when the monitor is in HDTV mode, using its native resolution 1920 x 1080. When i change to a lower resolution it only supports refresh rate of 75hz max. This can be a problem when im playing older games that dont have 1920 x 1080 resolution or if i jus want to use a lower resolution.

Also im using a ati 5870 graphics card with latest drivers installed and ati catalyst 10.11.

Please help me.
Thank you.

If your monitor doesn't support, there isn't much you can do to make it do something it wasn't designed for. You can go into Catalyst and try to force additional modes, but you run the risk of damaging your display and/or GPU. Have you tried that?

i have tried. but when i click 120hz , it automatically switches back to the native resolution 1920 x 1200. So when i run a game my resolution changes to the 1 in game for example 640 x 480 and it runs at 75hz. When i go catalyst to change to 120hz my resolution changes back to 1920 x 1200 and my game turns into a black screen.

I find it weird because if my monitor can support 120hz at 1920 x 1200, why cant it support 120hz for a lower resolution?

Btw, i cant use any other resolution other than 1920 x 1200 for 120hz even when no games are running, so its not the game's problem.

I got a few screenshots cos i know i might be a little difficult to understand.
As you can see my monitor can support 120hz but only at that resolution when its in the ''HDTV'' mode.
So, how come 120hz is not supported for lower resolutions in the ''basic'' mode.

bump. Anyone has a 120hz monitor? Or anyone know of a solution? anything??

EDIT:Another thing to note, i used some drivers like refresh force, it claims that the maximum refresh rate i can have is 120hz but ONLY at 1920 x 1200 and if i use other resolutions, its 75hz. How come??? Anyone know??

Please help. Maybe im missing some information here.

There is no point in running it at 120hz for anything lower than 1080p.

If a game is so old that it does not support 1080p, then it will not support 3d, in which case 120hz vs 60hz make absolutely no difference that you can detect.

Why did you buy a 3d monitor if you don't want to use the 3d? The eye can't tell the difference between 2d running at 60hz (or 75hz) and 120hz; it's just not possible.

In summary: There is no benefit to using a monitor at 120hz unless you are using it for 3d, in which case, any games that incorporate 3d will support that high resolution.

That is incorrect. There is a huge advantage to running at 120 hz. A recent review at Anandtech:

"Though the 120Hz refresh frequency does make games playable in 3D, there’s another important benefit of using a faster refresh rate - everything looks smoother, and you can now drive up to 120 FPS without tearing. The ASUS VG236H was my first exposure to 120Hz refresh displays that aren’t CRTs, and the difference is about as subtle as a dump truck driving through your living room. I spent the first half hour seriously just dragging windows back and forth across the desktop - from a 120Hz display to a 60Hz, stunned at how smooth and different 120Hz was. Yeah, it’s that different."

Check out the review, finally LCDs that can keep up with the old CRTs.
