Best 1440p monitor for FPS? Looking for all the bells and whistles.

post #1 of 9
Thread Starter 
Hello, I might be able to sell my old Achieva Shimian and was in the market for a new 1440p monitor. I am preparing for BF4 and was looking to get something that will perform and look good.

- Want 1440p, 120/144hz, IPS, looks good and isn't bulky like the old IPS Korean monitors, and something around $350-400.


The main questions I have are:

- Is there a huge difference between 120 hz and 144 hz in terms of clarity?
- Will a GTX 580 on stock clocks be able to display 1440p 120/144hz on medium for BF4?
- I was looking at the Achieva Shimian Edge and Crossover Black Tune, are they capable of achieving 120hz?

You are not going to get an IPS, 120/144hz display; at least there are none of quality that I know. If you really want FPS, TN panels are much better.

If you are willing to make the trade of extreme quality for the "smoothing" factor of 120hz, the two best panels right now are the Viewsonic VP2770, and Dell U2713HM. The Viewsonic is PLS, an upgrade to AH-IPS, an the Dell is AH-IPS.

Not well, no. I noticed a decrease in performance (about 65-80 down to 45-50'ish) moving to a 1440P on my Radeon 7970, and it's heavily overclocked.

Probably not.

I'm not sure about your question, but the Korean monitor thing is kind of a fad. I would never trust buying an expensive panel from via import from Asia via Amazon, and they're ugly as ****, but there are certainly users who enjoy them.

Not very big, but most 144Hz monitors has LightBoost, which has a very dramatic improvement in motion clarity if you have the GPU horsepower in order to do framerate=Hz (120fps@120Hz):


(From Photos: 60Hz vs 120Hz vs LightBoost)

For every 1ms of motion blur = add 1 pixel of motion blur during 1000 pixels/sec, from the sample-and-hold effect, as demonstrated & explained at TestUFO at www.testufo.com/eyetracking and in scientific references. This assumes, of course, the ideal situation of framerate synchronized with Hz.

There is a good list of 120Hz and 144Hz monitors, including LightBoost compatible models, and overclockable models. The overclockable models will not have the LightBoost motion blur reduction strobe backlight.

For Battlefield3 and Battlefield4, a GTX580 will generally benefit from neither 120Hz nor LightBoost, except for possibly the slightly decreased input lag of 60fps@120Hz. You will need to upgrade your GPU, or consider playing older games.

The difference between 120Hz and 144Hz is so small that you probably can't tell the difference. If we were talking 120Hz and 200Hz it would be a different story I'm guessing.

The best 1440p monitor for FPS is the Qnix QX2710 or the X-Star DP2710 (same monitor) because they overclock from 96-120Hz. Link here for $300.

The sexiest/thinnest looking 1440p monitors are the debezelled Qnix/X-Star. You can see what it looks like here (if you want more pics click the second link in my signature and scroll down).

Hmm, not sure if I want to give up 1440p for a 1080p 144hz monitor, stick with whatever I have, or find a 1440p monitor that can OC up to ~100hz.

Don't forget that going to a 144Hz monitor, is usually a LightBoost monitor, which is 1.4ms of persistence in LightBoost mode (frames that are visible for only 1/700sec -- metaphorically equivalent motion blur to 700fps@700Hz with lots of black frame insertion and 120 visible refreshes). LightBoost 100Hz has less motion blur than non-LightBoost 144Hz.

At your GPU levels, I'd totally say, upgrade your GPU first. Satisfaction ratio will be much higher by selling your 580 and going to a Geforce GTX780. Your games could be as smooth as this 120fps gameplay video (Note: not all systems can play realtime non-slomo 120fps videos).

Or.... you can buy an overlord pcb for your achieva and oc it to 120 hz? tongue.gif

Sorry, I must admit that wasn't quite clear to me.

What would you say is the best as far as Lightboosted TN panels go....Lightboosted 120Hz or Lightboosted 144Hz?

Apologies. It's an advanced topic. During framerate=Hz, motion blur is directly proportional to the length of the static refresh (the sample-and-hold effect). Reducing motion blur is done by shortening the length of a static refresh. There are two ways to go about that: Increasing Hz (more refreshes), or increasing black periods between refreshes (flicker, ala CRT, plasma, LightBoost, etc). Here, mathematically, when running at framerate matching refresh rates -- a strobed display running at lower refreshes using 1/X second strobes produces the same sample-and-hold motion blur as an "X Hertz" display.

Go to www.testufo.com/blackframes for a good animated example of this -- you will observe with your own eyes, a 50%:50% flicker will reduce motion blur by 50%. So on a regular non-LightBoost display, you're witnessing the equivalent reduced motion blur of twice the framerate, since the half strobing is eliminating half of the motion blur already. The blur trail halves in length. But if you increase the black period between refresh and shorten the visible refresh (e.g. 90%:10% dark:bright -- a briefer flicker -- shorter persistence) you will reduce motion blur by that proportion (90%) e.g. where you had 10 pixels of motion blurring, you now only have 1 pixel of motion blurring. It's witnessing the motion blur equivalence of a monitor that is running at ten times the refresh rate/frame rate, thanks to the shorter visible frame length. That is why, LightBoost, with backlight strobe flash lengths as short as 1.4 millisecond (1/700th second strobes), and when running at framerate=Hz, will mathematically produce a motion clarity equivalent to a flickerfree 700fps@700Hz display. (albiet, obviously, with more flicker/stroboscopic effects, due to the lower true refresh rate of 120Hz).

John Carmack's talk on QuakeCon, as well as Michael Abrash's writings, help explain things:

Makes no difference as nVidia limited LightBoost strobing to 100Hz, 110Hz and 120Hz. So the CRT effect is only available at those refresh rates. So you have to lower your refresh rate to 120Hz in order to turn on LightBoost.

Just that if somebody is buying a 144Hz computer monitor, they're probably buying a monitor that already has LightBoost built in, which means they have the optional choice of turning that feature on, to get far less motion blur, via the LightBoost strobe backlight. There's at least 6x clearer motion with LightBoost 120Hz than with non-LightBoost overclocked 120Hz, so that's a worthy consideration.

Modern LCD's are bottlenecked by a guaranteed minimum motion blur via the sample-and-hold effect ( www.testufo.com/eyetracking ) no matter how infinitely fast the pixels transition. Fixing this is by even higher Hz or by strobing.

e.g. During 960 pixels/second motion (panning of half screen width per second, as in www.testufo.com/photo )
Regular LCD 60Hz -- 16 pixels of motion blurring trail (corresponds to 16.7ms of hold time)
Regular LCD 120Hz -- 8 pixels of motion blurring trail (corresponds to 8.3ms of hold time)
LightBoost at 100% -- ~2 pixels of motion blurring trail (corresponds to 2.4ms strobe)
LightBoost at 10% -- ~1 pixels of motion blurring trail (corresponds to 1.4ms strobe)
(Assuming you run in the ideal situation of framerates exactly matching refresh rates).

Risk vs Risk. If you got a pixel perfect monitor with no backlight bleed, and really good contrast, then the $200 PCB might even end up being the tempting option. Avoids the Korea panel lottery. (That is, if you decide to go the overclock route). There is a lot to be said about IPS color quality on a monitor that you trust.

That said, if you don't have the GPU power to run at triple-digit framerates, I suggest the OP spends money on a faster GPU than a 560, to get a more fun 60Hz experience first, than to upgrade to 120Hz without being prepared with enough of a GPU. Once you have enough GPU, go ahead for 120Hz.
