My CRT died! New computer + 1440p & 120Hz? hmmm... - Page 2

post #11 of 16
I like my 120HZ 1440p, but with a single 680 it puts me to medium settings most games for around 100fps. It is nice though, but the pixel response time is definitely noticeable over a Light boost monitor, but just barely behind a regular 120fps TN, so it isn't too bad. Its hard to really notice, depending on who you are.

For what you've explained, of seems like the Light boost monitors might be my recommendation to you.

The main problem with the 1440p 120hz displays is it's pretty difficult to get high fps at 1440p. I mostly use my overlord as a secondary display now since I'm just not getting the FPS to use 100+ hz.

Thanks for the tip, it would be pretty pointless having a monitor with no system to take full advantage of it.


I suppose the CPU + Motherboard will cost me $1,200 at the minimum, and I will be spending $150 for cooling (sucks, but I will settle for now). I wish I could get a new SSD (Samsung Pro 512GB) next, but a strong GPU (780 classified for 290x) is definitely needed.



When the hardware is purchased, I will go with purchasing the BenQ display first; I suppose I need to do research on lightboost @ 144Hz vs 120Hz.

I'm glad you shared, I am definitely going to upgrade my computer first.

Whoah, what CPU and motherboard are you going for at $1200?? Intel's latest x79 extreme and then a mediocre board? Why not a 4770k and a pretty decent board for a combined $550ish?

Unfortunately, IPS 1440p 120Hz overclocks has at minimum 6 times more motion blur than LightBoost. Really nice colors if colors are important. But not good for motion blur. If you have owned a CRT as long as you have now, because of motion blur, then you better make sure you are familiar with LightBoost. LightBoost is a strobe backlight that flickers like a CRT, and create some nice "It's like a CRT" testimonials.. Here is a very useful quote below.

Also, ghosting is different from motion blur.
-- LCD Motion Artifacts 101
-- LCD Overdrive Artifacts
-- 60Hz vs 120Hz vs LightBoost

Motion blur is a function of how long the persistence is (and persistence has nothing to do with LCD GtG transition time -- persistence is the 'sample-and-hold' effect talked about Michael Abrash of Valve Software, and also listed in scientific references). The longer a frame is visible/static for, the more motion blur it can create. As you track moving objects on a screen, your eyes are in a different position at the end of a refresh than at beginning of the refresh. That causes the static frame to be blurred across your eyes (animation demo). This is the sample-and-hold effect. You reduce this blurring by reducing the length of a visible refresh -- either via higher Hz, or by black periods between Hz (CRT flicker, LightBoost flicker, black frame insertion, strobe backlight, etc).

When doing a motion at 1000 pixels per second, the milliseconds translates to pixels of motion blur (1 pixel = 1 millisecond during 1000 pixels/sec). This is the more vision-accurate MPRT response measurement standard, not the GtG measurement standard. TestUFO uses 960 pixels/sec as the default target motion speed, so this is very close to the easy "1 ms = 1 pixel". Therefore, this graph means approximately (+/- 0.5 pixel):



When converting milliseconds (MPRT) of motion blur, to pixels of motion blur:
60Hz LCD = ~16.5 pixels of motion blurring
100Hz LCD = ~10 pixels of motion blurring
120Hz LCD = ~8 pixels of motion blurring (overclockables are a bit worse due to ghosting).
144Hz LCD = ~7 pixels of motion blurring
LightBoost 100Hz @ 100% = ~3 pixels of motion blurring
LightBoost 120Hz @ 100% = ~2.5 pixels of motion blurring
LightBoost 100Hz @ 50% = ~2.5 pixels of motion blurring
LightBoost 120Hz @ 50% = ~2 pixels of motion blurring
LightBoost 100Hz @ 10% = ~2 pixels of motion blurring
LightBoost 120Hz @ 10% = ~1.5 pixels of motion blurring

This is quite obvious, since it is consistent with what is seen at www.testufo.com/ghosting

-- 60Hz; about 16 pixel-widths of motion blurring

-- 120Hz; about 8 pixel-widths of motion blurring

-- 120Hz LightBoost; 1.5 pixel-widths of motion blurring

Just view www.testufo.com/ghosting -- the motion blurring you will see, will be very similiar to one of the above photos. (Different monitor response curves and overdrive settings will affect things such as ghosting and coronas, so your monitor may not match my monitor and overdrive settings exactly, but the sample-and-hold motion blur is unaffected)

Also, remember input lag considerations, LightBoost does inject a minor disadvantage of an average of about half frame input lag (4ms), but many people say it improves their scores anyway due to the improved reaction time of the lack of motion blur. Ironically, LightBoost actually has slightly less input lag than a QNIX QX2710 overclockable. And you can still turn off LightBoost in a BENQ XL2420TE and still get near-CRT-equivalent input lag. You do have the choice of turning ON/OFF LightBoost. If you want ultralow CRT-like input lag, and you play really competitively, skip the overclockables. Besides, higher resolutions create lower per-GPU framerates. (Frame render times means extra input lag -- extra GPU lag).

With the XL2420TE, or a similiar monitor, easily turn ON/OFF LightBoost with ToastyX Strobelight:
LightBoost OFF -- CRT-like input lag
LightBoost ON -- CRT-like motion clarity (and still slightly less input lag than overclockables).

Overclockables are better for many people, but not necessarily for professional/competitive gamers. If you still want an overclockable, there are roughly about five choices in the List of 120Hz Monitors, along with LightBoost monitors and other models.

The Lightboost mod doesn't work at 144Hz...You have to use it with 120Hz.
