The VG248QE doesn't display 1440x1080 correctly with LightBoost. You have to use GPU scaling. Ok you guys just woke me up. I still have my VG248QE's. Going to test this out, as I do have a 1440x1080 display scaled 100hz resolution for my XL2720Z for 1:1 already. It was already hard enough to get the 1:1 and aspect (which are identical) scaling options to be available in the Benq OSD at this resolution, because the vertical size is seen as "native" to the monitor, which disables the OSD scaling options. I had to drop the Vertical total by 11 to get the aspect settings to work. This is what I used for 1440x1080@100 hz: (just a normal setting for max vertically sized 4:3 games with proper mapping). Horizontal: 1440, 88, 44, 148, 1720 Vertical: 1080, 4, 5, 25, 1114 Display scaled perfectly with 1:1 and aspect showing perfect 1:1 size. If the vertical is 1125 (or even 1124), Aspect and 1:1 become greyed out. And the video card panel aspect settings become ignored because it thinks the display is handling them. Fun stuff =.= Going to hook up my VG248QE now and see what happens with lightboost. BTW it's MUCH easier to get 120 hz lightboost working with bizarre resolutions (or even double strobed 60hz) than it is at 100 hz (which seems impossible). that's because the monitor may respond to vertical totals higher than 1149 to enable lightboost with 120hz strobing. Up to 1180 may work for 120hz strobing. The VG248QE goes out of range with a black screen with ANY Vertical total higher than >1195 (the Benq's don't, they just complain about "out of range!" and still show a signal with certain even higher VT's (probably designed for strobe crosstalk reduction) being accepted. (Try this on your VG248QE, toastyX you try it too if you're bored. 1920x1080 60hz refresh rate. Hor: 48, 32, 2080 Vert: 3, 5, 1179 VG248QE OSD reports 60 hz and Lightboost enabled. The Benq XL2720Z says it's at 120hz (probabaly because it identifies the vertical total for the refresh rate). (this is REQUIRED if using displayport). Monitor should enter 3d mode double strobed at 60hz (this is identical to the Benq "double strobe" option for 60hz but there seem to be random retrace tearing artifacts). If over DVI, the higher timings of Horizontal 88, 44, 2200, and Vertical 4, 5, 1179 will work also, but over DP, the monitor says "no signal". *edit* Ok I'm back. Yeah just use GPU scaling. The XL2720Z actually refused to enter lightboost mode at 1440x1080 with 1149 VT. It did enter lightboost at 1155 VT, but it had the same right side noise artifacts as the VG248QE. The VG248 entered LB at 1149. I think I remember long ago before I ever owned the XL2720Z that I tried to get display scaled lightboost working at something silly like 1024x768 or something awful and wound up with the entire screen at the bottom left corner ![]() |
