Today LG has officially announced what they call the world’s first 84-inch Ultra Definition (UD) 3D TV for the Korean market with the TV expected to start appearing in North America, Europe, Asia, and Latin America starting in September. What is interesting here is the fact that you get 4K resolution in 2D mode and more than Full HD in stereo 3D mode since the 3D TV set uses LG’s passive (FPR) 3D technology that essentially halves the vertical resolution in 3D mode. And the good news is that the 4K resolution (3840×2160) is actually fully supported by the HDMI 1.4 interface and thanks to the use of passive 3D technology you can also use the interface in 3D mode as well, though you’ll have to feed the TV set with Row Interleaved video data directly as HDMI 1.4 does not currently feature frame packaging support for more than 1080p resolution.
The 84-inch LG 84LM9600 Cinema 3D TV is definitely an interesting approach from LG as the company is clearly targeting to get a good market position among the 4K resolution TV sets even though they are still very far from becoming mainstream. And the good thing is that even the currently available technology allows them to support stereo 3D mode, though not in the full 4K resolution, but with more than enough pixels at 3840×1080 per eye for the 3D mode. 4K stereoscopic 3D support with active 3D TV sets at this time would be a problem due to the very high bandwidth requirements in order to push two frames at full 4K resolution, but with all the interest in 4K we are probably soon going to get a new revision of HDMI supporting frame packaged 3D at over Full HD resolution. The good thing from all this is that we are probably also going to have support for 1080p 60Hz frame packaged 3D mode sooner than later, so while 4K TV sets at every home is something still in the not so near future, we may all benefit from that even in the next generation of Full HD 3D-capable solutions.

Today Acer has announced in USA the release of their new 27-inch Acer HR274H 3D monitor using passive film-patterned retarder (FPR) technology, but at the same time it also apparently supports what Nvidia’s 3D Vision technology does (according to what Acer has released in the official press release)… falling into a category of products called “Optimized for GeForce”. But there is more, this monitor is equipped only with HDMI 1.4a interface and analogue VGA, there is no Dual-Link DVI. Acer HR274H apparently also features real-time 2D to 3D conversion built in the display, so it is done by dedicated hardware and should work with different inputs.
Acer HR274H 3D monitor specifications:
Panel Size: 27″ (69 cm) Wide Screen 16:9, TN, LED backlight
Native Resolution: 1920×1080 pixels
Pixel Pitch: 0.3114 mm
Brightness(Max): 250 cd/m2
Contrast Ratio (Max.): 100,000,000:1 (dynamic)
Viewing Angles: 170° H / 160° V
Response Time: 2 ms (Gray to Gray)
Video Inputs: 2x HDMI 1.4a, VGA
Power Consumption: 27.50 W On, 1.4W Sleep, 0.6W Off/Standby
Integrated Audio: 2x 2W stereo speakers
Monitor stand: tilt +30°~-30°
Dimension (WxHxD): 25.5″ x 18.5″ x 7.6″ (648.1 x 468.5 x 192 mm)
Weight: 13.2 lbs (6 kg)
It is interesting to not that the user has control over the 3D functionality that allows the activation of 2D-to-3D conversion on demand as well as the option to choose between not only frame packaged 3D input, but also Side by Side and Top/Bottom. And this is something that we did not have with some of the first 3D-capable monitors that came out with HDMI 1.4 interface also supporting stereo 3D.
Acer HR274H comes bundled with a pair of Acer-branded passive 3D glasses. And since it uses HDMI 1.4a interface, the 3D modes you are going to be limited are of course 720p 50/60Hz 3D and 1080p 24Hz 3D as well as 1080i 50/60Hz 3D mode. The new 27-inch Acer HR274H 3D LCD monitor should be available for U.S. customers at leading retailers with an MSRP of $599 USD. The European price of the 27-inch Acer HR274H should be at around 450 Euro and it should soon be available. There is also a smaller 23-inch 3D model with the same features and capabilities – Acer GR235HA, that is an alternative to Acer GR235H, but not the same model. The price of the Acer GR235HA monitor in Europe should be about 240 Euro.
Update: Ok, so it is not exactly official 3D Vision support, but instead Acer has licensed the GeForce 3D software driver from Nvidia in order to get the same game support, features, etc. as 3D Vision-ready active monitors do offer, but in the form of a passive 3D solution.

HP is finally joining in with a 3D LCD monitor, after the company also released a 3D-capable laptop quite a while ago in the Envy product line. What is interesting in this announcement is that the HP 2311gt monitor is a passive 3D solution and not an active 3D one as HP has shown last year with HP 2310g. So it seems that we won’t be seeing a 3D Vision-ready monitor for now from HP and they have apparently abandoned the idea to release the active HP 2310g 3D LCD monitor and have replaced it with the HP 2311gt passive 3D model.
The 23-inch HP 2311gt LED backlit 3D monitor uses Film Patterned Retarder (FPR) technology, offers native 1920×1080 resolution, comes bundled with 2 pairs of passive 3D glasses, Cyberlink PowerDVD software bundled to offer 2D to 3D video conversion and playback as well as DDD’s TriDef Ignition software for playing games in stereoscopic 3D format. This new 3D monitor from HP is apparently already available in some parts of Europe…
HP 2311gt Monitor Specifications:
Viewable Image Size: 58.42 cm (23.0-inch) diagonal
Display Type: TN LCD active matrix
Response time: 5 ms typical
Pixel Pitch: 0.265 mm
Brightness: 200-250 cd/m² (2D mode); 100 cd/m² (3D mode)
Contrast ratio: 1000:1 static; 3000000:1 dynamic (2D mode)
View angle: 170° horizontal, 160° (2D mode) and 12° (3D mode) vertical
Maximum Graphics Resolution in 2D: 1920×1080 @ 60 Hz
Maximum Graphics Resolution in 3D: 1920×540 @ 60 Hz
3D Glasses: 3D Passive FPR (Film-type Patterned Retarder) Glasses
Video Input Terminals: VGA, DVI, and HDMI
Power Consumption: 45 watts max, 33 watts typical, 0.5 watts sleep
Dimensions (W x D x H): 557.95×159.0x416.48 mm (21.97×6.26×16.40 in)
Maximum Weight: 4.3 kg (9.5 lb)
What is interesting is the fact that HP is giving out all the not so attractive specs that most of other makers of passive 3D monitors tend to “forget” to mention to the customers. I’m talking about things like the reduced brightness in 3D mode, the very small vertical viewing angle in 3D mode, the lower resolution in 3D mode. Most others just save you these important things and focus on the better points in passive versus active 3D solutions, leaving the impression that it is much better and does not have any drawbacks.
