Monitor does not allow 120Hz, but allows 121.

[FrozenImpact]

Hello,

I would like to know how to enable 120Hz refresh rate on my monitor instead of 121. If I put 120 in the resolution settings, the screen goes black for 10 sec and then turns back on with the 121 Hz rate.

I do have latest drivers for 7950

Dual link DVI

Thank you for your help

Is there a reason that you want it at 120Hz? If it looks smooth and works fine in real world tasks, then just leave it.

Do you need a reason to help a fellow tech guy? No offence

Its because 3D programs need 120Hz, they do not work on 121Hz. 121Hz is designed for desktop use, but I have noit figured out why programs cant turn on 120 by themselves nor can CCC do it.

I take it this is a CRT correct? Did you test the 3D program at 121Hz? The refresh rate is usually not going to be exact, just like how the frequency of a CPU or FSB is usually going to vary a couple of Hertz from what it is supposed to be.
Have you tried different resolutions to see if you can get a more stable refresh rate? What about other monitor controls in your video-card’s control panel like the sync settings?

To play in 3D, you do not have to set your monitor to a specific refresh rate. The software used for 3D will do that, assuming its capable of getting the right refresh rate.

Jesus its like any other forum here. I dont have CRT monitor, its not 1999 here anymore.

...And thats exactly the problem, the 3D problem cant enable 120 HZ, it gives a black screen

Is it possible the cable is bad? Maybe a bent pin or something? The other possibility is you need to find drivers for that monitor.

Wait, you are running an LCD/LED monitor at 121Hz? I have never seen an LCD/LED monitor that goes that high; they usually top out at 75Hz because they don’t need it; even 60Hz is usually more than sufficient. Again, have you tried different resolutions to see if you can get a stable 120Hz or tried altering the video-card settings?

120hz monitors are fairly common. ASUS even has one that reaches 144hz. They are most commonly used for active display 3D gaming, but a lot of people like them for high responsiveness and fluidity. They require either displayport or dual link DVI-D connections for the most part, though HDMI 1.4b has recently been available as an option too, I just haven't seen one using it yet.
