Gsync and TN vs IPS

[namarino]

I'm getting ready to build another pc this Christmas. It's going to have a 4790k and a GTX 980 ti. I'm looking for monitors right now and I've narrowed it down to three. the ASUS MG279Q, the BenQ XL2730Z, and the ACER XB270HU. I'm going to wait to see what kind of deal I can get over black friday and cyber monday. But I have a couple of questions. 1) Is gsync worth it for this machine? I'm thinking that I could just turn Vsync on and as long as it doesn't go over 144fps (which it very rarely will at 1440p) I won't experience any problems. Maybe I have that wrong. 2) Will I notice the difference between IPS and TN in terms of response times? The only fast paced game I really play is TF2 and I might get into counter strike at some point. Anyway thanks for your help. It is very much appreciated.

Dynamic Frame Sync

Most people that have 75+Hz and dynamic frame sync (Free/G) swear they'll never go back

VESA's Adaptive Sync/FreeSync/G-Sync are all better than VSync because they adapt to the refresh needed.  

 

Response time and color on IPS/TN

You'll get much better color on a modern IPS panel

You likely won't be able to see a difference in "response time" on modern panels @ 6ms and under with 75+Hz and either ULMB or a Dynamic Sync (Free/G) (unless you pick a cheap POS with massive input lag)

TN is a dying breed.

 

You'd likely be extremely happy with any of your three selections.  I personally prefer Asus of those three choices simply because they typically have better quality control.

Ok great, thanks! I'm really trying to stay away from Gsync right now because it's expensive and, in the future, I might want an AMD card which would render Gsync useless. Could you explain the whole vsyn thing? If my refresh rate is 144 hz and my gpu is putting out less than that, where is the problem? I always thought the problem arose when you went above the refresh rate.

Tearing can happen at any framerate, whether it's above or below the monitor's refresh frequency. It just happens more often when it's above.

 

V-Sync limits your GPU's framerate to 144fps (or whatever your monitor's max is) so it doesn't send out any extra frames to the display, to eliminate tearing. Whenever you can't maintain 144fps, it drops down to 72fps and shows each frame twice. This creates a sort of juddery mess if you can't maintain above 144fps at all times, as it rapidly switches between 144 and 72fps.

 

G-Sync instead asserts control over the monitor, and instead of refreshing at fixed intervals it just waits and refreshes whenever the GPU happens to have a frame ready.

Oh ok, so basically there is no point in having a 144 hz monitor if you are unable to maintain your fps at that level??? Unless it has some sort of adaptive sync technology of course.

That's only with V-Sync on. If you just run without any synchronization you won't have that issue, though you'll have to deal with tearing if that's something that bothers you a lot.

Oh ok gotchya. Yeah screen tearing bothers me a lot. The only thing that I'm not crazy about with Gsync is how  expensive it is and how un-future proof it is.  What if in the future I decide to get an AMD card? Then I just spent all that money essentially for nothing. What would you recommend for the machine that I'm going to be building? Which monitor would you recommend?

Basically that's how I think of it, the acer is an awesome monitor

Interesting. Ok well then I'll probably just save up for the Acer...it's a bit expensive...haha

Yeah, I'm in a very similar situation where I'm looking to build soon but I haven't decided on a monitor (my thread for that is here). I like the look of that Acer but it's currently 749€ everywhere here in Germany and I'm not sure if I want to spend that much on a monitor. Anyway, good luck deciding!

http://www.beachcamera.com/shop/product.aspx?sku=LG27MU67BOB Awesome monitor at a awesome price freesync is the best new feature for a monitor. Gysnc provides the same function at with 150 to 200 cost added to the monitor.

AMD/ Nvidia need to reconcile on the GSync/FreeSync technology.

They basically want the consumers to pick side by buying "insurance" when they pick their monitor.

If you pick FreeSync monitor now, your next GPU upgrade will be locked on AMD. Same goes for GSync/Nvidia.

It'll be hard for Nvidia to support FreeSync albeit they are "Free", because GSync doesn't won't sell anymore if they do so.
