understanding vsync and monitor refresh rate
« on: Fri, 22 November 2013, 10:14:55 »
As I understand it, vsync will reduce the fps that your video card puts out and align with the Hz of my monitor. So my video card doesn't go over 60 fps if I have a 60Hz monitor and will effectively reduce tearing, etc.

I guess my question is, if I were to get a 120Hz monitor, would I notice much difference? Do any of you have 120hz screens with high-end gpu's? What are your thoughts? I've had the same screen for 5+ years, but I think my video output is possibly better than the refresh rate on my monitor.

Same with mechanical keyboards, once you go 120Hz you never go back.

Personal opinion, but I can tell a 120Hz screen from a 60Hz any day of the week.

Same with mechanical keyboards, once you go 1440p you never go back.

Personal opinion, but I can tell a 1440p screen from a 1080p any day of the week.

This too. ****ing love my 1440p panel.

Anyway, on 120Hz Monitor gameplay is a lot smoother you have twice as much the refresh rate.

I'm bad with words, watch this video:

Do you guys have any good recomendations for a 24" panel thats 120hz?

I have two Asus VE248Q which cap at 76HZ, it may be time to start looking into something else.

ASUS VG248QE is 144hz, but still 1920x1080, meh may try it and see how much of a diff it makes.

I think 120hz is a good feature.. but the lightboost imo is what you should be after.

it flashes the backlight of the panel @ 120hz or 60hz.. this removes some of the perceived motion blur inherent in lcd panels..

This essentially inserts a black frame between each lit-frame.. 

The lightboost and 120hz are good for MOTION...

However, the trade off is,  very bad color reproduction.. and since it's TN, theres the viewing angle problem compounded by the usual lack in luminance uniformity in this genre.

Still.. if you play FPS games.. It's stupid to play them on 60hz ips when you can get 120hz lightboosted tn panels..

The only time a 60hz monitor is better than a 120hz is when its an IPS panel

Eizo is now offering a 240hz monitor i would love to give that one a try some day.

You should wait for the gsync refresh if you're interested in ASUS VG248QE. I think gsync could be a big deal, as it dynamically changes the refresh rate to match the FPS instead of locking the FPS to 30/60/120 jumps so I think this will be a much smoother approach.
The biggest problem with higher refresh rates is generally you have to put up with bad color TN panels. There are a few 1440p IPS that can OC to 96 or possibly up to 120Hz with luck of the draw...
QNIX QX2710 Evolution 2    
X-Star DP2710    
Overlord Tempest X270OC    
Catleap 2B    
so I would look at those first if 60Hz isn't cutting it for you. But then again, you will need minimum of GTX670 4GB for your GPU if you want to go there.

Hmm, thanks for the heads-up on the gsync, I think I might just wait for that then.

That's the problem with vsync, as I understand it, vsync creates input lag when it reduces the frame rate from the gpu. So, this dynamic hardware control (gsync) sounds cool. I would love to see one in person. Looks like it wont be available for a few months tho :(

I have enough gpu to push it. It's frustrating turning everything to Ultra, only to enable adaptive/normal vsync because the screen is tearing.

Yea thanks for that heads up.
I ordered a VG248QE from Amazon warehouse deals to try (I figure if I saw no or little diff I'd just send it back) and just canceled it.
I'll be watching for the Gsync refresh to come out next year.

You can get Gsync TODAY if you want to.. get the panel, and the mod board, and plug it in.

OR...  buy the eizo fg2421..

If you're into gaming.. nothing tops that monitor. because the strobe is a 'supported" feature and not a hack.

Vsync- Caps game frames per second at 120 fps or 60 fps ( Remove Screen Tearing)

Refresh rate - The rate of which the monitor display images. 60hz On most monitors. 120hz and above on "gaming" monitors

Ideally you want to be able to play a game at 120fps on a 120hz monitor.

You can Vsync to ANY chosen refreshrate.. but certain games only allow 120 or 60 due to their physics system.
