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.

    Any word on if this will support lightboost?

  • 2 Tim // Nov 29, 2011 at 21:30

    Where can I buy it?

  • 3 steve // Nov 29, 2011 at 22:28

    Lightboost is to brighten shutter glasses results, i dont think they’ve have any effect on a polarized display.

  • 4 Bart // Nov 30, 2011 at 01:01

    Passive already cuts the resolution in half, and having only 720p capability will make 3d games look like shit. Passive can be the future but they need like 4k resolution and then you get 1080p to each eye.

  • 5 Bart // Nov 30, 2011 at 01:04

    wouldn’t the monitor just be supported as a 3dtv play monitor? 3DtV play already supports passive TVs, and it should be fine with 1.4a.

  • 6 josh // Nov 30, 2011 at 09:05

    i agree with part, i tried sly cooper collection on my aw 2310 monitor and the 720p 3d looked like shit.

  • 7 xwing // Nov 30, 2011 at 10:35

    But you have to pay for 3DTV Play, Acer payed for that support upfront in this case so it should end up cheaper in the end than if bought seperately (bulk order, like with free games with graphic cards). Also, bonus points for their marketing guys so they can advertise it as the only 3D Vision certified passive 3D monitor.

  • 8 Rust // Nov 30, 2011 at 18:21

    But my Zalman 22″ monitor can play games at 1650×1080(540) at 60Hz. It is Nvidia certifiyed too. But its not HDMI 1.4…

  • 9 Vicki // Nov 30, 2011 at 20:59

    So, being new to the whole 3D thing, and not even being sure if I am interested in 3D gaming….how does this monitor compare to the PLANAR SA2311W 120Hz? Thanks for input everyone :-)

  • 10 Bloody // Nov 30, 2011 at 21:04

    I still haven’t seen these new monitors as they were just announced, but the interesting thing is that although they support HDMI 1.4, the products like these two monitors that are “Optimized for GeForce” will not be limited to 1080p 24Hz 3D mode only. When used for gaming in stereo 3D mode the driver licensed from Nvidia will be outputting row interleaved 1080p at 60Hz. The HDMI 1.4 limitations for stereo 3D will be applied only when using consumer electronic devices…

  • 11 chizow // Nov 30, 2011 at 22:46

    Really interesting find here Bloody.

    Two main things that pop-out:

    1) Nvidia is willing to support passive eyeglass/non-Nvidia branded 3D equipment *IF* you license 3D Vision. This is a 180 from some of their positions in the past with passive solutions or “rogue” solutions like the newer Samsung 120Hz solutions.

    2) Nvidia is also willing to support some different output methods over HDMI since you mentioned row interleaved output to achieve half-resolution 60Hz per eye in 3D. Again, only if you are willing to license 3D Vision. This will not make those who have been waiting for CB support happy…..

  • 12 josh // Nov 30, 2011 at 23:25

    i am confused from reading through this article and comments. i own the ASUS VG278H? The 3d vision effect looks great so far with Batman AC, (minor ghosting). Will this Acer HR274H, perform equally in terms of 3d vision with 3d vision ready games?

  • 13 Bart // Nov 30, 2011 at 23:28

    But that’s not a Nvidia limitation bloody. It’s just that HDMI 1.4 doesn’t have the bandwith to do 1080p 60hz in 3D, and has nothing to do with Nvidia.

    Maybe 1080p 60hz interleaved most likely doesn’t use up as much bandwith and 1080p 60hz frame packed?

    So we would get almost 720p per eye in interleaved mode? that wouldn’t be that bad with the coupled benefits of reduced ghosting and much brighter output. I’m looking to upgrade my 3 acer 24″ with a new 3D vision surround setup. These would be nice if they pass your tests bloody.

    Thanks, and great blog.

  • 14 Bloody // Nov 30, 2011 at 23:41

    I don’t think that Nvidia is very interested in supporting DLP CB as the user base of these is not that big and is not growing as there are no new products supporting it being released. On the other hand passive 3D is enjoying quite a lot of user interest mostly because of the lower price and the cheaper glasses. So it is reasonable to support it in some way, the good thing is that you might get to have 3D Vision functionality on a passive 3D display as an alternative to the iZ3D driver or the TriDef 3D software… we’ll see how well this goes.

    As for HDMI 1.4, I didn’t say it is an Nvidia limitation, but so far Nvidia only supported stereo 3D over the 3DTV Play software and that had to go by the limits of the HDMI 1.4 interface. But with the “Optimized for GeForce” certification Nvidia has decided to directly feed the passive 3D monitors with row-interlaced images instead of relying on the HDMI 1.4 specs and thus you’ll not be as limited as with what HDMI 1.4 supports for stereo 3D.

    1080p 60Hz row interleaved uses the same amount of bandwidth as 2D 1080p at 60Hz as it is essentially transmitting 2D images at 1080p resolution and with 60Hz and the image gets split by even and odd rows and each of these forms the left and right eye image. So in the end you get half vertical resolution per eye in stereo 3D mode with all these passive 3D displays, unlike active 3D solutions where you get the full resolution per eye.

    Not yet sure if you could pair three of these into a 3D Vision Surround setup however. I hope to be able to test one of these to see how well will they work in 3D…

  • 15 chizow // Dec 1, 2011 at 01:36


    I agree the most interesting bit about this release is the fact Nvidia is willing to support displays that don’t use their own hardware and active shutter technology. Certainly something to keep an eye on for the future.

    The benefits of passive polarized in terms of cost is certainly a key selling point, especially as you add number of users, although I’m not really sure this monitor is priced competitively in that regards. $600 is the same as the HN274 with its true 120Hz refresh and full resolution 3D capabilities and only $100 short of the new Asus with LightBoost. Both displays include a pair of active glasses, a 2nd one will add a bit to the cost but I think they are clearly the superior options over this display at similar price points.

    Also the bit about CB support was actually more about the Samsung LCD HDTVs that support CB (unofficially), not so much about the older DLPs. From what I’ve seen, 1080p CB @ 60Hz per eye is far superior to framepacked 720p @ 60Hz. Similarly, I’m sure this interleaved 1080p option is probably better than the 720p or 24Hz alternatives also. Just another option I guess that’s not quite as good as 1080p @ 60Hz but not as bad as bad as framepacked 720p @60Hz. I’ve also seen numerous requests for 720p SBS over framepacked, so again, this may open the doors for more driver-level supported outputs for a wide variety of displays.

  • 16 Bart // Dec 1, 2011 at 03:27

    Hopefully you get a review sample soon. Have you tested any 3D TV’s that are passive with 3D vision?

  • 17 Bloody // Dec 1, 2011 at 11:23

    Passive 3D TVs are not compatible with 3D Vision, you need to use 3DTV Play over HDMI 1.4 and in 1080p 24Hz 3D mode if the 3D TV has more input lag the result is awfully annoying (like in the case of LG 42LW5500).

    These Acer passive 3D monitor should also work in 3D Vision Surround setups and that would certainly be interesting thing to see and test.

  • 18 john-boy // Dec 1, 2011 at 13:38

    Hello Bloody,

    You had said Acer was coming out with something new soon and I suppose this is it.

    I will be curious to hear what you think when you get a unit to work with. I bought the Acer HN274 last spring and it is Beautiful!!!! I have no complaints with it. Of course being a huge fan of all things 3D I am interested is what new and improved.

    Enjoy it and thank you for your constant help in answering my questions and thank you to everyone who helps me learn (I need alot of help haha).


  • 19 Bloody // Dec 1, 2011 at 14:11

    Well, not exactly, Acer should also soon have an updated version of the HN274H that should also support 3D Lightboost technology…

  • 20 quadrophoeniX // Dec 1, 2011 at 17:55

    Bloody, I wonder if the info you gave on 3Dvison compatibility (1080i /60) was confirmed by either Acer or nvidia?
    Wouldn’t it be possible that the monitor could also accept 1080p/120 as a native “2D” input and be detected by Geforce drivers as generic 3Dvision compatible display and be used without compromises with external 3Dvision emitter and glasses?

  • 21 optical10 // Dec 1, 2011 at 18:08

    this is getting confusing, I just sold my Acer HN274 3D LCD monitor and purchased the new Asus VG278H 3-D monitor with light boost but apart from lightboost making it easier to see my Logitech illuminated keyboard whilst wearing spectacles and the shutter glasses and a dedicated button for different game, RGB, daylight, etc output levels and even with the Asus F keys pop in and out on the fly controls, I must say I prefer playing PC games like lost planet #2 on the older Acer. It’s picture was bright enough, the Acer had less crosstalk and the 3-D went into the monitor at the default settings much better than the new Asus.
    However what I have always wanted is 3-D monitor that would allow me to watch virgin media broadcast side-by-side 3-D as well, which I guess this new Acer passive monitor will do, but not that 1080 p 100 Hz quality? so if the price is reasonable this new passive Acer monitor should be as good as a Samsung (or other make) 3-D TV at side-by-side broadcast viewing?
    27 inch does me just fine as I do all my viewing of cable and TV/game playing space on my desktop but I guess there isn’t a one hardware solution that dusk 3-D game in 1080 p 120 Hz and side-by-side viewing at around 32 inches?

    Any help much appreciated and thanks for your very informative blog.

  • 22 Bloody // Dec 1, 2011 at 18:57

    quadrophoeniX, the information has been confirmed by Nvidia. There is no chance of using these passive 3D displays with 120Hz refresh…

    optical10, try lowering the Contrast of the Asus to about 50-55 in stereo 3D mode and it will have less crosstalk as compared to the Acer and will still be bright enough thanks to the Lightboost support.

  • 23 quadrophoeniX // Dec 1, 2011 at 21:28

    Bloody, thanks.
    I know that 1080p/120 in 3D is impossible on passive polarisation with current technology per se. That just did not rule out that the monitor could accept and display 1080p/120 in 2D mode – and thus support 3Dvision natively. But if the info comes straight out of Santa Clara then for sure not on this one….

  • 24 mogbert // Dec 3, 2011 at 21:39

    Very interested in seeing this monitor in person. A previous passive screen I had seen wound up not working for two reasons. Couldn’t see a good 3D picture closer then 4ft from the screen (I sit 2.5ft from my monitor), and any solid color areas, particularly lighter areas, showed a noticeable horizontal lined pattern (during 2D use). Browsing the web, when the screen is mostly white, showed the trouble the most.

    The confusion about 180p60Hz and 1080p24Hz modes is because in the 24Hz mode, the computer sends out the signal as a 3D format and lets the TV do the heavy lifting. The 60Hz mode puts the heavy lifting inside the video card and send out the signal as a regular 1080p60Hz signal that just happens to already be interleaved.

  • 25 Greg Gilbert // Dec 21, 2011 at 15:53

    Anyone know when this thing will be for sale? It was introduced in November but still no word when it will be available. I even called Acer and the people I talked to didn’t know.

  • 26 Ryle // Dec 24, 2011 at 21:57

    Had it. Nvidia 3D Vision plug and play over HDMI, works exactly the same like a Shutter Monitor with Nvidia support. 3D objects seem more like a pop up book, the depth is the same as a shutter Monitor. Like any other passiv Monitor, horizontal viewing angles in 3D are bad, 10° up and the effect is gone.

    Like a passiv LG Monitor I also tested you see horizontal lines in the panel even in 2D. Blacklevel is terrible, it´s more a dark grey.
    So I brought it back.

  • 27 Greg Gilbert // Dec 28, 2011 at 02:24

    What country they currently selling it in Ryle? The website exists for the monitor in Australia I believe. Are you there?

  • 28 johnboy // Jan 12, 2012 at 19:51


    I thought I’d post this link to Newegg for the New PASSIVE 3D Acer Monitor


  • 29 Rust // Apr 16, 2012 at 13:27

    WOW! It is Incredible! I play Skyrim on this monitor. No, not “play” – I live in Skyrim ( 3D effect SO really)!
    The BEST 3D solution, imho… Depth of view MORE then gaming on 65″ TV, because I sitdown near 50cm(20″) from this amazing monitor.

  • 30 Grant // Jul 1, 2012 at 21:50

    Passive 1080p is NOT 720p to each eye, a 1080p screen is split verically giving a 960×1080 image to each eye,

  • 31 Bloody // Jul 2, 2012 at 01:09

    Actually with passive 3D the screen is not split in half, but is instead divided in even and odd horizontal lines with all of the first responsible for showing the image for one of the eyes and all the others showing the image for the other eye. As a result of that you are getting half vertical resolution per eye (half of the horizontal lines for each eye), so the actual resolution that each eye sees is 1920×540 and not 960×1080 as you may think.
