The VG236H can be a bit clearer than the VG23AH during fast camera pans but the VG23AH has less over-shoot on dark colours. Using 72hz speeds up the response time and reduces over shoot even more. Ghosting isn't an issue on either @60hz though. The VG23AH is one of the fastest 60hz displays I've used, really only the Samsung 700/950D displays are better since they don't ghost at all.

1) Used ToastyX tool (just look up CRU tool) to add the 72hz resolution. Had to reboot for it to show up as an option in the monitor properties, but it seems to work well. Here are the settings again:
Horizontal Active: 1920
Horizontal Front Porch: 30
Horizontal Sync Width: 40
Horizontal Back Porch: 45
Horizontal Total: 2035
Horizontal Sync: +
Vertical Active: 1080
Vertical Front Porch: 3
Vertical Sync Width: 4
Vertical Back Porch: 5
Vertical Total: 1092
Vertical Sync: +
2) The default settings on the TriDef3D installation were wrong. I would have a scaled down display with 3D in it and black bars on the outside edges.I had to go into the TriDef3D control panel and make the following changes:
Manufacturer: (standard display types)
Model: Line Interlaced (1920x1080)
SBS works too, butevery time I loaded a game with 3D, I would have to press buttons on my monitor, navigate the (crap) menus to select Side by Side. With Line Interlaced, its automatic and I don't have to fiddle with the monitor to get the 3D to work.
3) Adjusted several settings on the OSD menu for TriDef3D (while in game press the NUMPAD 0 to bring it up). Here are the settings that I chose that worked best without making my eyes crazy or tired from the 3D (adjust the depth to what feels comfortable to you).
Scene Depth: 20
Percent in Front: 90
Custom Focus: On
Near Plane: 60
Far Plane: 100
This gave me a nice balance with very little ghosting, but still a decent 3D effect. This monitor does not like the default settings that the TriDef3D software uses. It could be the reason why the reviews for this unit were so bad..
Anyways, as long as I bypassed the AMD settings for the 3D display on the TriDef3D control panel, and adjusted the settings above everything works perfectly. I am very happy with the color, contrast, and 3D ability of this monitor now.

The VG23AH's biggest downside is that Asus does not include clear instructions as to how to get the 3D to work. You need to buy the Tri-Def 3D software (50$) for games+movies, or you can use Power DVD for 3D movies.
I set up the VG23AH and compared a few 3D movies to my Nvidia 3D Vision VG236H. The lower resolution is visible sometimes (more so with CGI like the water in Tintin 3D), and it looked as if some one turned town the anti-aliasing a little bit. The loss of sharpness is minimal though. For movies I prefer passive 3D since the sharpness loss is minimal while the IPS colour gain is large.
Since the VG236H is glossy it always looks clearer as well. There is less of a screen door effect on the VG23AH than the BenQ XL2420T since the VG23Ah uses semi-glossy coating while the BenQ uses medium AG.
The colours and blacks are way better on the VG23AH since it is IPS and Passive 3D does not require one to crank the brightness unlike Nvidia 3D Vision 1 displays.
You have to sit around 2.5-3ft away and have the VG23AH @ head level to get the full Passive 3D effect. You can sit as close as you want with a Nvidia 3D display, but since they are all TN, similar height restrictions apply.
I tried Arkham City before and it looked liked a sub-hd 3D game w/o anti-aliasing, same with Dirt 3. In Orcs Must Die 2 everything looked great, sure it wasn't as sharp as a Nvidia 3D display but the colours were better and I can play @72fps.
I couldn't get BF3 to work properly with the Tri-Def trial since it put the image in a little 680x480 box in the top left corner.

I reviewed a PA238Q last year, the VG33AH is superior in every way except for the bezel style & colour control options. Granted the PA238Q I received was awful (Contrast 30% lower than other test units and 50% lower after calibration, very washed out gamma & severe light bleeding), even if I had received a "good" unit the aggressive anti-glare coating alone was enough to send it back. If I wanted a permanent film grain effect & dirty+sparkly whites & light colours I would smear a thin layer of Vaseline and sprinkle some sand on it myself.
I'm starting the Written Review Here: http://wecravegamestoo.com/forums/gadgetry-electronics-discussion/11673-asus-vg23ah-review-semi-glossy-72hz-passive-3d-ips.html#post849785
by tomorrow night I will have a majority of the content in there.
Mine doesn't have any light bleeding but the bottom left corner is a bit brighter
The black level on the right display is 0.05 vs the VG23AH's 0.15 @140cdm/2 brightness
I tried Orcs Must Die 2, Dirt 3 and Ghost Recon: FS (GR:FS does not support 72hz, it switches to 60hz) using the Line Interlaced mode and they looked way better, and I can simply turn the 3D on/off with 1 button press in the tri-def options vs going through the displays OSD. I forgot how awesome 3D could be. When using the sbs mode GR:FS switched to 1920x1080@24hz and I still can't get BF3 to work properly or Arkham City to use high graphics settings when tri-def is enabled.
