Yeah. V2 firmware also (apparently) had some kind of panel or electronics swap (people who sent in their V1 monitors got completely *different* panels back (e.g. they actually marked on them to see) that has much better image quality even at the exact same settings.
They still didn't fix the strobing issues, though. I'm almost completely sure the strobing problems at 100hz are simply a scaler bug. If Benq adjusted the old Mstar scaler from Lightboost mode (Vertical total 1502=lightboost crosstalk settings btw, even though this VT does not TRIGGER lightboost...it's sent to the scaler via the LC panel), they probably forgot to include the fallback strobe settings (e.g. whenever the vertical total defaulted away from the normal VT for the refresh rate, the monitor would switch to 60hz backlight pulse widths (strobe persistence=pulse widths) but strobe in sync with the current refresh rate).
I didn't actually realize what benq did with the original blur reduction until I tested Lightboost mode on my XL2720Z.
I found out that Lightboost mode on XL2720Z @ 120hz refresh rate is 100% IDENTICAL in strobe crosstalk, and persistence value, to Benq blur reduction at 120hz refresh rate, Strobe duty 009, and Strobe phase 000, and vertical total VT 1500. Like 100% fully identical. In benq blur reduction mode, there is 1 line of UFO's of strobe crosstalk at the top at strobe duty 009 and strobe phase 000 (this goes for ANY refresh rate with VT 1500 applied), and the exact same pattern is shown in Lightboost 120hz strobed mode (VT 1149=120hz lightboost).
(note: Strobe phase = "Area" in XL2730Z, but the scaler no longer uses the vertical total to calculate area crosstalk anymore, which was a "feature" (you could call it a beneficial bug) of the older XL Z series, which had to do with lightboost communication with the scaler, it's why VT tweaks worked on the older Z series, but this was limited to VT 1502 (a 1440 translated screen vertical size according to the scaler internal information (1280x1440 was reported by the scaler on the 1920x1080 monitor when VT 1497-1502 was applied!).
(if anyone cares, the reason why VT 1485 would show "Out of range!" but still show a screen, was because the scaler would think that VT 1485 was 1920x1440, which is out of parameters for the monitor, while 1280x1440 is "within" parameters, but this applies to the OLDER Z series; the XL2411T, XL2420T, TE/TX and XL2720T responded the same way (same scaler, Lightboost mode used).
They simply adopted the lightboost signal for customizable blur reduction (with extra electronics and a wire to turn on the strobe signal) and used the same scaler tricks that Lightboost did itself, except benq blur reduction defaulted to the normal VT for the refresh rate (1144 at 120hz, 1133 at 100hz), which is why the crosstalk is so high without the "Lightboost" level VT 1500/VT 1502 tweak).
I know this probably makes no sense to anyone except PCM2, but if Benq simply forgot WHY the VT 1500 tweak even worked and didn't include the strobe settings from the old scaler (Mstar) into the new scaler (realtek), that explains the strobe bugs in this monitor.Edited by Falkentyne - 9/19/15 at 11:55am
