Asus VG23AH is a New 23-inch Passive 3D Display with IPS Panel

April 18th, 2012 · 3 Comments · General 3D News


It seems that Asus is interested in trying out the passive 3D (FPR 3D) monitor market as the company already has a two active 3D monitors on the market. Their first FPR 3D model to hit the market is the 23-inch Asus VG23AH that uses an IPS LCD panel with LED backlight, promising high viewing angled and better color reproduction in 2D as well as 3D mode. The monitor features built-in 2D to 3D autoconversion mode and supports 3D over HDMI 1.4 only, even though the display has a VGA and a DVI port that apparently don’t work with 3D (unless of course you are using Row Interleaved stereo 3D output to the display that should work regardless of the interface). You get the monitor bundled with no HDMI cable however, so make sure you have a spare one, so that you can immediately start using it in 3D mode


Asus VG23AH Specifications:

Panel Size: 23.0″(58.4cm), Full HD 1920×1080
Panel Type: IPS LCD, LED backlight
Pixel Pitch: 0.2652mm
Brightness(Max): 250 cd/m2
ASUS Smart Contrast Ratio (ASCR): 80000000:1 (dynamic)
Viewing Angle (CR>=10): 178°(H)/178°(V)
Response Time: 5ms (Gray to Gray)
Display Colors: 16.7M
3D Technology: FPR 3D Technology
Signal Input: 2x HDMI 1.4, D-Sub, DVI-D
Power Consumption: <40W (Typical), Power Saving/Power Off Mode <0.5W Phys. Dimension with Stand (WxHxD): 550.2x419.5x250mm Net Weight (Esti.): 6.5kg

The monitor supports HDMI 1.4 frame packing for automatic stereo 3D input as well as Side by Side and Over/Under available for manual selection and of course the built-in 2D to 3D conversion that you can activate. One thing that Asus fails to mention however is if they bundle the monitor with some kind of software that will allow you to play games in stereo 3D mode or you have to arrange that yourself. No mention in the press information, the product page, even the manual does not clearly say anything, although the manual mentions a few times that the monitor is 3D Vision ready (no mention about it being “Optimized for GeForce” certified product). The good news is that since the monitor is passive 3D you should be able to directly output in Row Interleaved stereo 3D mode on it and putting the 3D glasses you should be able to see the stereo 3D image. Meaning that it should work just fine with the iZ3D driver or the TriDef 3D software, although you might need to get separately a license for these middle-ware solutions (if you don’t already have one). The fact that the monitor supports HDMI 1.4 might make it compatible with Nvidia’s 3DTV Play, although probably not officially since this is clearly a 3D monitor and not a 3D HDTV. And the last option would be the support for the Nvidia “Optimized for GeForce”, although not very likely.

AOC d2357Ph is a New Passive 3D Monitor with Thin Bezel

March 21st, 2012 · 2 Comments · General 3D News


AOC has introduced a new 23-inch passive 3D-capable monitor with that is only 10.6 mm deep and with a thin 5.8 mm frame – the AOC d2357Ph. The design definitely catches your attention, and thanks to the thin bezel you might want to consider using these monitors for multi-monitor setups in 2D or stereo 3D. AOC d2357Ph uses LED backlight and thus achieves the thin design, although it even has integrated speakers, supports HDMI 1.4 interface with frame packaging as well as row interleaved 3D and comes with a 2D to 3D conversion capabilities.



AOC d2357Ph 3D Monitor Specifications:

– Panel Size: 23 inch/58.5 cm, 16:9, Full HD, WLED LCD
– Response Time: 2ms in 2D mode (Grey to Grey), 5ms (typical)
– Maximum Brightness: 2500 cd/m²
– Maximum Contrast: 20,000,000:1 (dynamic), 1000:1 (typical)
– Viewing angle: 170º (H)/170º (V), @ C/R > 10
– Pixel pitch: 0.265 mm
– Signal Input: 2x HDMI 1.4, VGA (Analogue)
– Power consumption: On: < 36 W; Standby: < 0.6W - Product with stand: 533.3 x 399.3 x 120 mm - Product with stand: 4.87 kg

The new 3D monitor from AOC comes with 2 pairs of polarized 3D glasses, 1 normal and 1 clip on for people wearing prescription glasses. And although it is not mentioned, the monitor should be coming with the TriDef 3D software bundled for the stereo 3D support as AOC is an OEM partner of DDD and there is a special version of the TriDef 3D package intended for AOC 3D monitors. The AOC d2357Ph is scheduled to be launched in April 2012; the recommended retail price will be 239 Euro in Europe, not yet information about pricing and availability in North America. Considering the price of the previous 23-inch passive 3D monitor from AOC (the e2352Phz available for $299 USD), you can expect that the AOC d2357Ph should be available at a similar or a slightly higher price.

Make Your Passive 3D Monitor or 3D HDTV Work with 3D Vision

February 11th, 2012 · 184 Comments · GeForce 3D Vision


Not that long ago Nvidia has introduced their “Optimized for Geforce” program that allows some certified passive 3D monitors such as Acer HR274H and Acer GR235HA to work with the 3D Vision video drivers, allowing you to use the full 3D Vision functionality with a passive 3D display. Prior to that in the old stereoscopic 3D drivers Nvidia had support for passive 3D monitors from Zalman, and although the newer Zaman 3D monitors were bundled with the iZ3D driver and not anymore with 3D Vision, they actually do work with 3D Vision and get optimized for the Optimized for GeForce functionality. If you have a passive 3D LCD monitor or even a passive 3D HDTV that is not supported by 3D Vision (Optimized for GeForce) you can actually quite easily make it work by installing a monitor driver with EDID override that will tell Windows and the video drivers that you actually have a different compatible display.



Here is an example using LG’s D2343P passive 3D monitor with installed Zalman ZM-M240W 3D Monitor EDID Override and the LG gets recognized as a Zalman 3D monitor. You need to install the INF driver from the link over the monitor driver you currently have installed from the Windows Device Manager, using the Have Disk option and if when get a warning message just confirm that you want the driver installed anyway. After that you may have to restart Windows in order for things to start working and the Nvidia video drivers to be able to properly recognize and activate the 3D support.



Opening the Nvidia Control Panel and going to the Stereoscopic 3D settings page you should see the “Optimized for GeForce” logo if everything is working properly and clicking the Test Stereoscopic 3D button should bring the Nvidia 3D test on the screen that should be working just fine when you put on the passive 3D glasses that came with the monitor. After that you can the 3D Vision Photo and Video Player and even play games in stereo 3D mode just like you would with an active 3D display and with the 3D Vision glasses. Of course using passive 3D would mean that you would have some limitations like the half vertical resolution when in 3D mode, the lower vertical viewing angle etc., but still you will be able to use passive 3D displays with your Nvidia graphics card and with all the features that 3D Vision offers, an not only with the iZ3D or the DDD TriDef 3D drivers, so you will simply have one more alternative available. I’ve tested this method and it works just fine even with the latest 295.51 beta video drivers from Nvidia, so you should have no trouble making it work. If you try this on your passive 3D setup, feel free to share your feedback and how it works with your specific 3D hardware, thanks to Butmuncher for finding out about this method.

Update: Since the Zalman EDID override does not support audio for HDMI connection to the monitor, you should use this driver only for DVI connection to the passive 3D display. If you wan to use HDMI connection and have audio over the interface as well, then you should install the Acer EDID override driver. Both INF files are included in the archive below, and special thanks to Greg Gilbert for providing the dump from the Acer HR274H display.

Here you can download the EDID override INF files that you would need for this to work…
