Philips 273G is a New 27-inch 3D-capable Active LCD Monitor

November 26th, 2011 · 9 Comments · General 3D News

Although Philips has not been very active in the field of 3D-capable monitors, the company is apparently trying to join that market with the release of the 27-inch Philips 273G3DHSW 3D monitor with active shutter glasses. It is interesting to note that the company is jumping directly to the 27-inch size, but then again this monitor is equipped only with HDMI 1.4 interface, so it could be targeted mostly for 3D multimedia use, not stereo 3D gaming. Of course you would be able to use it with a PC to play games in stereo 3D mode, but you’d be limited at 720p resolution with decent refresh rate due to the specifics of the HDMI specifications.

Philips 273G3DHSW 3D Monitor Specifications:

Panel Size: 27 inch/68.6 cm, 16:9, Full HD, W-LED LCD
SmartResponse: 2ms in 2D mode (Grey to Grey), 5ms (typical)
Maximum Brightness: 300 cd/m²
SmartContrast: 20,000,000:1 (dynamic), 1000:1 (typical)
Viewing angle: 170º (H)/160º (V), @ C/R > 10
Pixel pitch: 0.311 mm
Signal Input: 2x HDMI 1.4, VGA (Analogue)
Power consumption: 24.79 W on mode, <0.5 W off and standby Product with stand (mm): 642 x 440 x 227 mm Product with stand (kg): 8.2 kg

Philips is bundling the 273G3DHSW 3D model with DDD’s Tridef 3D software and you’ll also need a compatible ATI/AMD-based video card to use the monitor for playing games with the software on your PC. The monitor is not yet officially supported by Nvidia’s 3DTV Play and since it is a 3D monitor and not a 3D TV it will most likely not be added as an officially supported product. The Philips 273G 3D monitor is expected to be available in Europe in December or January with a price of about 499 Euro, no word yet on US availability and pricing.

Sony’s PlayStation 3D Display Starts Shipping This Weekend

November 11th, 2011 · 9 Comments · General 3D News

The wait for Sony’s PlayStation 3D Display is almost over as the monitor should start shipping this weekend and more precisely on November 13th in North America at least, but the availability should soon follow in other regions as well. The 24-inch LCD screen with full HD 1080p 3D support over HDMI 1.4 interface could be a nice addon for PlayStation 3 gamers, but unfortunately won’t be that attractive to PC gamers. Even if you are not into stereoscopic 3D gaming, the PlayStation 3D Display has another interesting feature called SimulView that will allow multiplayer gaming with each of the players seeing only his own gameplay – no more split-screen gaming. You can watch the latest introductory video from Sony about the PlayStation 3D Display’s features embedded above if you are still not familiar with the product.

The PlayStation 3D Display has been available for pre-order for a while already…

More on Ghosting and Brightness of the Asus VG278H 3D Monitor

November 9th, 2011 · 26 Comments · GeForce 3D Vision

The new Asus VG278H 3D Vision-ready 120Hz LCD monitor has an interesting option in the OSD menu that allows you to control the level of the 3D Lightboost and thanks to that I was able to try some interesting things. In the review of the Asus VG278H 3D monitor I have already mentioned that there are some things that you can do in order to improve the results you will get when using the monitor. One example for that is to reduce the Contrast level from the default setting of 76 to 55 in order to reduce the level of ghosting/crosstalk in stereo 3D mode without sacrificing too much of the brightness and that is possible thanks to the 3D Lightboost technology that increases the brightness level. I’ve used a colorimeter to measure the level of brightness with the different settings of the Contrast level with the Lightboost set to the maximum level and here are the results:

Contrast 100: 202 cd/m2
Contrast 76: 160 cd/m2
Contrast 55: 111 cd/m2

And here is the level of brightness with the default setting for Contrast of 76 and different level of the Lightboost setting, from completely off to the maximum:

Off: 85 cd/m2
+1: 90 cd/m2
+2: 95 cd/m2
+3: 102 cd/m2
+4: 111 cd/m2
+5: 120 cd/m2
+6: 128 cd/m2
+7: 136 cd/m2
+8: 144 cd/m2
+9: 152 cd/m2
Max: 160 cd/m2

Notice that from the Off state of the Lightboost technology to the maximum level there is almost a double increase of the brightness level and what Nvidia was saying for the new technology was that it will increase the brightness twice. So you can say that this claim is true. Notice that the level of brightness you get with the decreased Contrast to a setting of 55 is the same as the +4 state of the Lightboost setting together with the default setting for Contrast. So you are kind of halving the effectiveness of the Lightboost technology in order to further reduce ghosting/crosstalk.

In order to further reduce the ghosting in 2D mode as well you can also play with the Trace Free option of the monitor. The default setting of 60 is quite Ok (the left part of the image above), but increasing it to the maximum value of 100 you get better results (the right part of the image above). You can see from the high-speed photos taken from the PixPerAn test software that the fast moving objects are looking better and have less ghosting with a higher value of the Trace Free function.
