The real factor that should influence your decision is to go for whatever is available/cheaper where you live, which about a month ago meant if you are in EU get the XL2411T, and if you're stateside get the VG248QE.


Thanks, but I really don't care about the price nor the availibity. smile.gif I cannot compare the monitors without knowing the values and thus I cannot decide which to pick.

Is there any values about these monitors anywhere or do they simply not exist? Are everyone just assuming they're the same, because they share the same panel?

PC Monitors has values for both

Hmm, thanks. All I could find is says XL2411T has smaller than 2ms, but VG248QE is just over 2ms. That's not very precise.

Only an oscilloscope can provide precise measurements and currently only PRAD.de uses one to measure input lag and they don't have either of these displays lined up to review in the next month.

Like their predecessors, the VG248QE and XL2411T have negligible input lag, end of sonnet. The BenQ has better colors, so, if money isn't a problem get the BenQ.

Alright, thanks!

Yeah you really don't need to worry about input lag on either of them. They both have very similar input lag - that is to say it is so low it is impossible to detect unless you're robotic. wink.gif

LightBoost adds a slight bit of input lag when compared to Instant Mode. The question is how much (present consensus seems to be about 1 frame of input lag due to instant mode being disabled) If true and confirmed, it is technically possible other monitors may keep instant mode. This is possibly done using a very brief partial buffering (the length of pixel persistence, 1-2ms) and doing a slightly accelerated LCD scanout, due to the extended blanking interval between frames, needed to settle pixel persistence, to get clear LCD frames, before the strobe backlight flash, as seen in a high speed video). Samsungs are WAY worse in strobe mode (over 20ms lag), while I can't feel the input lag of LightBoost monitors. Especially when I use the tweak to disable Control+T, since that method has more input lag. Due to the faster human reaction times during fast motion due to LightBoost, some people who can't feel the input lag remarked it feels like there's less input lag with LightBoost than without, due to the better motion clarity.

Although it wasn't done for this purpose, TFTCentral does have an oscilloscope with photodiode, they posted their TFTCentral review:
TFTCentral's tests of LightBoost -- Motion Blur Reduction Backlights

For that article, they focussed on the motion blur elimination / stroboscopic science for this article, so I don't think they tested input lag though using this equipment; it was to generate some strobe graphs of the stroboscopic backlight; this article primarily focusses on motion blur. The numbers they have are nearly identical to the ones I measured using my oscillscope; with 2.4ms strobe lengths for LightBoost=100% and 1.5ms strobe lengths for LightBoost=10%. This is well within an error margin (approx +/- 0.1ms), as I independently measured 2.4ms for 100% and 1.4ms for 10% a few weeks ago.

Perhaps contact them and inquire about input lag measurements of LightBoost?

can anyone hit me up with a good ICC profile they are using with amd cards?

Anyone?

There is one here for amd scroll down a bit on the page:
