In what aspects 27" 2720Z monitor is worse than 24" version?

Hi,
I saw someone, somewhere here, posting about flaws that bigger panels have, that smaller version don't have.

For example, so far I found:

The 27" panels (XL2720T LightBoost and XL2720Z BENQ) have more strobe crosstalk than the 24" 1ms panels (XL2420TE, XL2411Z, XL2420Z)

I remember reading about something even more serious (or maybe this is serious?). I just don't remember what it was, since I was never going to buy 27" (too expensive). Maybe the latency (lag)?

But I happened to have some luck, and bought 2720Z for a great price. Now I'll have 2411Z and 2720Z for a brief period of time, and I don't want to make a mistake choosing which one should stay with me.

I'm really demanding in terms of motion quality. I was perfectly happy with my XL2411T, the newer Z version is somewhat inferior, but it's a minor difference, and I'm glad I upgraded from 2411T to 2411Z. But I don't know if I could handle significantly worse motion quality at 60 and 120Hz (I can live without using 144 if I have to, but 60 and 120Hz are both very important (console/PC gaming))
I also play Battlefield 4 a lot, so more lag could be troublesome.

edit: Of course we're talking about V2 in both monitors. I upgraded the 11Z and it won't be a problem with 2720Z if I'll get V1 out of the box

Thanx in advance for the (if any) answers.

I don't have the 24" one, but on the Lightboost Asus monitors (VG series), the 27"'s had worse ghosting (slightly worse motion clarity) than the 24" versions did. The VG248QE had almost flawless lightboost motion clarity..almost completely indistinguishable from a CRT. You only saw RTA/ghosting artifacts on the very top and bottom (particularly if contrast were toned down) and only if you looked for it

The 27" versions, however, had much better image quality (the contrast ratios and color fidelity dropped like a rock on both, when lightboost was enabled, although apparently the 27" maintained a slightly better contrast), but there was no LB purple tint on the 27" monitors. You could improve the motion clarity slightly by lowering the contrast on the 27".

Since the same manufacturer makes the panels for both Asus and Benq, I would assume the 27"'d also had slightly better IQ, but a bit worse ghosting than the 24"s (although Benq's AMA simply looks bad on both, compared to Asus tracefree's overdrive)

Thanx

I compared them side by side with image cloned.

You're right. 24" version is able to achieve almost CRT quality of motion. 27" version has really noticeable ghost following the moving objects and there is nothing I can do about it.

Well, I'll have to decide, and it won't be an easy decision. 27" version SEEMS to have a little better image quality (colors/contrast). I might be wrong since I didn't try to set them both 100% equally.
I'll have to make more comparisons. For now I've spent only 5 minutes on this side-by-side tests.

The 27 VG27HE/H or whatever the model was, was similar.
Higher ghosting, but better IQ in Lightboost mode.
The ghosting was partially fixable by lowering the contrast setting.

The Benq monitors, however, don't lose contrast in BBR mode (unlike the lightboost monitors). Lowering contrast from 50 to 40 can help certain image transitions noticeably.

Hello, sorry to bring an old post back. Which 24" monitor are you talking about? Thank you.

[Falkentyne]

Any 24" lightboost monitor.
Almost all of the 24" lightboost panels use the exact same AU Optronics panel, anyway, and lightboost uses per line overdrive.
TBH, I found that you can make the 27" 2720Z lightboost look almost IDENTICAL to the 24" panel's lightboost mode, ghosting quality wise but you have to drop the contrast to 0. The 1000:1 contrast ratio in lightboost mode, and not degrading the colors, is the 27" big advantage over the 24", and you lose that all by dropping the contrast to 0. At contrast 0, though, compared to the VG248QE, the lightboost clarity is almost exactly the same. And at least you have the option of getting the high contrast ratio and "decent" colors (unlike the VG248) by going to contrast 37 (purple tint effect starts at contrast 40 on the 2720Z, white clipping point starts at contrast 45, and the white crush yellow effect starts at 50. In non lightboost mode, contrast 43 has perfect grayscale reproduction and the white clipping point starts at 51 contrast)
