Acer HR274H is a 27″ Passive 3D Monitor with 3D Vision Support

November 29th, 2011 · 33 Comments · General 3D News

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 2311gt is a Passive 23-inch 3D-capable LCD Monitor

November 1st, 2011 · 5 Comments · General 3D News

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.

Acer GR235H is a New 23-inch Passive 3D LCD Monitor

September 14th, 2011 · 7 Comments · General 3D News

Acer is one of the most active maker of 3D-capable computer monitors and they just announced another 3D model, this time it is a more affordable 23-inch Full HD display using passive polarizing filter or FPR (Film-patterned Retarder) technology and passive 3D glasses. The monitor comes bundled with a pair of 3D glasses and the TriDef 3D software that you need to use for gaming in stereo 3D mode and the playback of 3D multimedia content. There is also apparently a built-in 2D to 3D autoconversion functionality that you can activate from the OSD menu on the monitor and as it is not tied to software you should be able to use it with just about any content such as non-3D photos, movies and even games. The monitor uses a LED backlight and comes with a 2ms TN non-glossy panel, it has only VGA and HDMI inputs (they should be HDMI 1.4) and has built-in speakers, you can see the detailed specifications below…

Acer GR235H 3D Monitor Specifications:

– Display size: 23-inch (diagonal) 3D LCD
– Active Display Area: 509.76×286.74mm
– Contrast Ratio: 100,000,000:1 Max. (Dynamic)
– Brightness: 250 cd/m2
– Response Time: 2ms
– Maximum Resolution: 1920×1080
– Maximum Refresh Rate: 60 Hz
– Pixel Pitch: 0.265 mm
– Panel Technology: Twisted nematic (TN), 6bit + Hi-FRC
– Number of Colors: 16.7 million
– Screen Treatment: Non-Glare
– Viewing Angles (CR = 10): Horizonal: 170°, Vertical: 160°
– Input Signal: VGA, 2x HDMI (with HDCP)
– Speakers: 1.5W x 2
– VESA Wall Mounting: 100 x 100 mm
– Power Consumption (Energystar On): 31.7W (typical)

Apparently the monitor is hitting Europe this month with a price of €222 Euro as well as some Asian markets and will probably soon be available in other regions as well. I’ve actually heard about this model quite a long time ago, so I was a bit surprised that the announcement was delayed so much (it was expected to appear around March), but then again Acer had some delays with all of its 3D-capable models released this year. What is still missing is the new 27-inch Acer HS274H HDMI 1.4-enabled 3D monitor using Acer’s active shutter glasses that was also expected to be released earlier this year, even a bit before the GR235H. But now it seems that LG will have some more competition in the area of passive 3D monitors, although the big winner from all this is apparently DDD as all of the new passive 3D monitors seems to be bundled with their TriDef 3D software.
