I've never used 120hz LCD, but I recall faintly -- I was very young -- using 120hz 1024x768 on my brother's huge Syncmaster monitor back in the day, but those memories are quite faint and I find myself now, quite addicted to the wonderful, vibrant colors of my IPS displays, very curious if I would appreciate more the colors of an IPS panel or the fluidity of a 120hz/144hz display. I don't really have the GPU to run most games at 120hz anyway, so I haven't bothered to buy one and find out, but I think after my GPU upgrade I will look long and hard at 120hz.Having used my new monitor, 120hz or 144hz is a huge improvement over 60hz though. I wont be able to go back now. Even if IPS has the colors, it can't compete with this as far as smoothness goes.

Sorry, this is just a mega super pet peeve of mine: "irregardless" is not a word. Use "regardless" or "irrespective".
Wonderful post otherwise.
Irregardless originated in dialectal American speech in the early 20th century. Its fairly widespread use in speech called it to the attention of usage commentators as early as 1927. The most frequently repeated remark about it is that “there is no such word.” There is such a word, however. It is still used primarily in speech, although it can be found from time to time in edited prose.

I'm not sure what you're getting at here. Are you saying that the only factor in blur these days is the mixing of the current and previous frame which occurs when the pixels are actually transitioning?

Meadows wrote:It's a matter of perspective. You are right, but it's just semantics at this stage. The phrase "motion blur" is the terminology used in science papers and academic papers -- and also includes human-vision-induced motion blur -- and is totally 100% the widely used terminology. Therefore, I continue to use the term.Motion blur is not applicable to computer displays. At all.
It is an effect that actual moving objects leave on a recording device. (Whether the object or the recording device is the one that's moving is irrelevant.) Pixels don't move, they flash and persist, and if the persistence is too lengthy, that becomes a special kind of ghosting. Motion blur, as a term, is applicable to the human eye/vision and digital and analogue cameras, but not displays.

Unless they can show that the leading and trailing edges of the displayed movement are of the same delay (I doubt it)
Meadows wrote:Okay, "perception of motion blur". Perhaps this term is more acceptable, and that's what many papers use too, because "perception" is key (also covers artificial blur).it remains an artificial approximation of motion blur and thus unworthy of the sacred term.

Hi Mark,
I got really excited when I saw your update about two of the Samsung 3d monitors being capable of better motion performance without the need for a Geforce card. I just successfully tested my S23a700D and it worked so this one can be added to the list as well. I was able to get up to a tempo of 25 or so on the pixperan readability test and still make out the individual letters.
The only problem is that the screen dims, and I get an added 20-30ms of input lag that makes mouse movements feel a bit “soupy”. I play Quakeworld online (usually at 600 fps to reduce tearing-no vsync) and actually found even with the added input lag, I was able to track other players much easier and pull of twitch shot kills that I normally wouldn’t because of the blur I normally get when spinning 180 degrees quickly. It would be incredible if someone could somehow hack the firmware of these monitors to remove the input lag, with some brightness/color tweaking I’d leave this mode on all the time.
Thanks for you continued research, look forward to this becoming a feature of lcd’s in the future. It really removes that last barrier to crt-like performance.
Matt
(Editor's note -- input lag is a problem only with Samsung strobe backlights. The ASUS/BENQ LightBoost is much better for input lag, especially the BENQ one)

Try it out and see for yourself. Believe me, the difference with Lightboost and without it are friggin nuts. It's been a long time since I was last called an aimbotter in CA (I blame being slightly famous), but it happened just today. I'm hitting accuracies I used to hit back in 2010-2011 after playing 1 weekend with this thing, and that's after 2 years of inactivity.

So I finally got the VG248QE hooked up last night and was able to play around with it for a couple hours. The other monitor that I have is a HP ZR30W which is a 30" 2560x1600 IPS monitor so I will be comparing the VG248QE to that a lot in this review.
Right off the bat, I noticed the color quality seems to be a lot worse than the ZR30W. Everything looks to be washed out, dull and not to mention the monitor suffers from poor viewing angles. On the ZR30W, there is next to no color shifting when I move my head around unlike the VG248QE, but that's a common problem with all TN monitors. I tried calibrating the monitor a little bit using some of the values posted online, but it still doesn't compare to the HP.
Moving on, the first thing I tried was 144 Hz gaming. I loaded up Borderlands 2 just to see how it is and I can definitely say it felt smoother. There is no screen tearing at all on the ASUS, unlike how it is on the HP if i don't turn on Vsync. Although the game felt smoother at 144 Hz and there was less blurring, I found that having to play on a lower res (1920x1080 vs 2560x1600) and poorer color reproduction made the overall gaming experience WORSE. Granted this isn't a competitive, online FPS game so I might have benefited more from having a faster refresh rate, but I would have probably stuck with playing this game on the 30" IPS monitor rather than a 24" TN.
At this point I felt like I may have wasted $300 bucks on a monitor that is full of compromises. The next thing I tried of course was using the Lightboost hack. This was the main reason why I bought the monitor in the first place since there are plenty of other 120 Hz monitors that I could have gotten that I'm sure had better color reproduction.
So I downloaded the hacked INF file and followed Mark's instructions. After turning on Lightboost, I noticed the monitor became a little bit brighter so I loaded up PixPerAn just to verify everything is working. The first thing I noticed was that I can actually read "I need more socks" at full speed! This was cool since I've never been able to read it going so fast before on any LCD monitor.
I then proceeded to load up Borderlands 2 again not having much expectations. The first thing that happened was I noticed the FPS drop down to around 1-2 fps, but then I remembered to hold down "Ctrl-T" for a few seconds to turn off the 3D effect which fixed the FPS problem. So I loaded up a game and the first thing that came to my mind was...
SWEET MOTHER OF GOD!
Am I seeing this correctly? The last time I gamed on a CRT monitor was back in 2006 before I got my first LCD and this ASUS monitor is EXACTLY like how I remembered gaming on a CRT monitor. I was absolutely shocked and amazed at how clear everything was when moving around. After seeing Lightboost in action, I would have gladly paid twice the amount for something that can reproduce the feeling I got when playing on a CRT. Now I really can't see myself going back to my 30" 2560x1600 IPS monitor when gaming. Everything looks so much clearer on the ASUS with Lightboost turned on.
If you do any kind of gaming, you should definitely get this monitor. For everything else however, an IPS monitor would probably be better.
Thankfully I am lucky enough to have both
