ATI Radeon AMD HD 6670 2GB Won't Go Past 1920x1080 Resolution

I used to have a GeForce GTS 250 made by BFG Tech and when I was playing Diablo3 my entire system just shut off and it turned out that my graphics card died.

So I used my onboard graphics card and forgot about removing the old NVIDIA drivers from my GeForce GTS 250.

I purchased a ATI Radeon AMD HD 6670 2GB card off of EBAY and shut down my system and installed the card, needless to say my computer wouldn't go past the "Starting Windows" screen so I restored the computer to a previous date, and a bunch of other stuff and finally got my system to boot with the Radeon AMD HD 6670 and the drivers actually installed and I can see the Radeon AMD HD 6670 in my device manager.

My problem is ... it won't go past 1920x1080 .. I've tried the DVI cable, the HDMI cable, I've tried changing it in the Windows 7 Resolution Settings and the Catalyst settings but it won't go past 1920x1080 ....

I know something isn't working correctly but I don't know how to fix it ...
is there anyone out there that might know how to fix this so my card will display it's advertised resolution?

The advertised resolutions are:
3d Resolutions 2560x1600
Max Resolution Analog 2048x1536
Max Resolution Digital 2560x1600

and the max it is showing me is 1920x1080 in windows 7 and using Catalyst.

This is the card I'm talking about:

DIAMOND AMD Radeon™ HD 6670 PCIE 2GB GDDR3
Diamond Multimedia AMD HD 6670 | Buy Latest AMD HD 6670 Video Card | PCI Express x16 2GB GDDR3

It's going to be whatever the max resolution of your monitor.
If your monitor is 1920x1080, then that will be the max resolution.

If you want to run at 2560x1600, you will need to purchase a monitor that has that resolution.
The Dell 30" Monitor as well as other 30" monitors from LG and Samsung do that high resolution.

Only problem you are going to have is games aren't going to run that great at that high resolution since your video card isn't powerful enough.

Hello and welcome to the forums, DavidAllenNeron!

Checking the specifications of your card from this AMD website has revealed that your card does not support resolutions beyond 1920x1200 using the HDMI 1.4a (HDMI cable) specification and only outputs 2560x1600 via Dual Link DVI from your monitor.

What is the native (highest supported) resolution of your monitor ?

EDIT: Seems like your monitors native resolution is 1920x1080p.. it's no wonder you can't select a higher resolution than that

is there any way I can achieve a higher resolution with my current setup ?

Sigh...

If you really want to, at the risk of damaging your own hardware, try using this software to make custom resolutions for your monitor.

Disclaimer:- I bear no responsibility for what may or may not happen to your computer from using this program. Increasing the resolution of your monitor beyond its native defaults could permanently damage your monitor. I use this program myself (fully registered) to make custom resolutions, but those that are lower than my native resolution for gaming (since my laptop's card can't support quite a large number of modern games at my native 1080p resolution)

It just seems odd to me that my old GeForce card was able to display 2560 x 1600 on this same monitor but this newer Radeon HD 6670 won't display past 1920x1080..

Was your desktop icons and taskbar really really tiny?
At 2560x1600 on a 22" screen, everything is going to be really small, if your card was letting you use that res and scaling to to 1920x1080 output.
The monitor you have can only accept a max 1080P input signal.

I've included an desktop at 2560 scaled to 1920.
