27" 120hz monitor without OCing?

post #1 of 5
Thread Starter 
Folks,

not wanting to litter the forum with too many tangentially related threads, but all this monitor research is causing brain swelling.

Can someone recommend 27" 1440p monitors that run at 120hz without needing to be OC'd? Nervous of the OC process. Price not a problem.

This is as close as you can get, but technically it still needs to be OC'd

http://overlordcomputer.com/collections/27-displays

On paper, DVI can't even physically handle 2560x1440 at anything above ~90hz. Even if a monitor had 2560x1440 120hz DVI out of the box, you'd still have to hack the drivers to get it to run at that speed.

Unfortunately, no 1440p displayport monitor I know of "overclocks" or has anything other than 60hz native refresh. You shouldn't be afraid of "overclocking" a monitor though... that's really a bad name for it. As far as I know, you can't damage or overheat your GPU or LCD by forcing a custom refresh rate. The only issue I've run into is the hacked drivers messing up adobe flash.

Hi Bruce,

can you point to a good resource that explains the 'OC' process? That might take some of the concern off it.

Assuming that OC process is 'safe', what 1440p 27" model would you recommend where cost isn't a big concern? Are there any with more than one input port? I would like to connect an xbox or PS3 to the second port, for example, but am not sure if that would interfere with or prevent the 120hz OC?

As far as I understood the only screen with reliable overclocking and no frameskipping is the Qnix/X-star with only DVI-D. other screens state they overclock but have frameskipping or other issues.

edit: the best post about it is the club on this forum http://www.overclock.net/t/1384767/official-the-korean-pls-monitor-club-qnix-x-star

Overlord did a decent overview.

Basically, you start by running the AMD or an Nvidia pixel clock patcher to remove the artificial limitations in your graphics drivers. You then download and run CRU (Custom resolution utility), and set 2 or 3 detailed resolutions with the refresh rate you desire. "LCD, reduced" is generally the best option to use, and you should slowly bump up the refresh rate like you're overclocking a CPU until you start seeing weird visual artifacts.

Unfortunately, the only "overclockable" monitors are the ones with DVI-only input and no built in scaler, meaning they probably won't work with consoles.

Like snowpetrel said, the Qnix monitors or monitors from a boutique like Overlord are probably your best bet. I'm not sure what the current situation is, but only some monitors have the "overclockable" PCB.
