Why won't my monitor go up to 144hz

Today I was at microcenter, and I saw the ASUS VG248QE just staring at me, aching for me to buy it. So I do the logical thing, and buy the monitor. When I get home I set it up, and it won't go higher than 60hz. Here are my system specs:

AMD fx-8150(slightly overclocked)

AMD Radeon hd 6850 (overclocked) in Crossfire

G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM 1600

GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX

and an intel 120 gb SSD (can't remember the details)

I installed the latest catalyst drivers and it still wont work. Is this a problem with AMD Cards on this monitor? Because I saw on the website and CD there were only NVidia Drivers.

How are you connecting to the monitor? HDMI? You need to use a DVI cable for the 144hz refresh rate

Do you have a dual link DVI cable?

Is the video card seeing the ASUS VG248QE as such or just as a genetic monitor.

I am using a Dual Link DVI cable, and the computer does recognize the monitor. I just tried using the downsampling tool to "force" the 144hz onto the machine, but it did nothing. Any other suggestions?

In the Catalyst control panel do you see any options for frequencies over 75Hz.

I did see a post that listed these instructions... use at your own peril.

"*UPDATE*

I have solved this issue without third party software. If you are using an AMD GFX.

-First go to AMD catalyst and look under Information, then Software.
-Look for the 2D Driver Path. Make a note of the Path as you'll need it later.
-Go to start menu search for RegEdit
-Open Regedit as Administrator (You must open as admin otherwise regedit will not save changes).
-Open the folder as described in the 2D driver path.
-Look for a registry file in that folder called DALNonStandardModesBCD2 click Modify then add your chosen custom resolution to the list. (Mine was for 1440x900 14 40 09 00 00 00 00 60 - the last two digits denote refresh rate)
-Exit Regedit
-Reboot
-Check Windows display and Catalyst Control to see your new resolution"

I'm not sure how you would set 144Hz in that setting, maybe 01 44 at the end. So possibly 19 20 10 80 00 00 01 44.

I just tried that, and in catalyst and windows it shows my monitor is configured for 144hz. Unfortunately when I checked the information screen on my monitor it only showed that it was running at 60hz. It seems that the monitor just doesn't want to go up to 144hz.

I am guessing that your video card might not be capable of output at 144Hz, perhaps open a ticket with the video card manufacturer. You might also want to drop out of crossfire and see if there is any difference. Apart from that I am out of ideas.

I only do this because i care said:

Have you tried using both DVI ports on your video card? Most AMD cards these days, only have one dual link DVI-D connection, and one that is single link only.

Thank you for this, the answer was so simple that I completely overlooked it.

So to use my 144hz monitor @ 144hz it's DVI > HDMI?

To use a 144hz monitor, it must be Dual Link DVI-D, Displayport or HDMI 1.4b (not likely supported).

Ok so the DVI cable I have that I've been using for 2 years will be perfectly fine with a new 144hz monitor then. I shouldn't need to buy a display port cable.?

Most likely not. Most DVI cables are not "Dual Link".

Ok so the "daul link" is the extra pin DVI cables and they are required for monitor to display high resolution and higher then normal hz refresh rates?

Edit: I just went to checked the cable I have is not a dual link but digital, it's missing the center pins.

So it is digital, but not dual link.

It won't work for 120hz.

Most these monitors come with a cable that will work.

Thank you for your help on this.. I actually wondered on newegg and bought the http://www.newegg.com/Product/Product.aspx?Item=N82E168...

40 bucks off normal price + promo of 30 bucks off. I can't beat that deal. From the unboxxing it comes with the cable, so all good.

thank you again my love.. great talking with you.
