HP 2311 gt 23" Monitor Review: Passive, Polarized 3D On A Budget

Polarized Displays: Potentially Vendor-Agnostic, But Not

One of what we consider to be the biggest potential benefits of passive polarized screens is, in theory, full support for both Nvidia’s proprietary 3D Vision standard (via 3DTV Play) and AMD’s HD3D open standard. HDMI is ample for 60 FPS gaming at 1920x1080 on a passive display because the visual information needed for both eyes is available in one frame of video. That is to say, it doesn't require 120 Hz to facilitate 60 FPS. The obvious caveat is that vertical resolution is halved.

When it comes to testing the theory behind this, AMD’s HD3D does deliver stereoscopic 3D at 1920x1080, 60 FPS over HDMI on HP's 2311 gt without a problem. Nvidia's 3D Vision/3DTV Play solution, on the other hand, does not work.

We mistakenly assumed that Nvidia’s 3DTV Play would recognize and work on the HP display. However, the recent 301.42 driver build was unwilling to enable the feature when we plugged in Nvidia's 3D Vision emitter. A little research revealed that the company's drivers are somewhat picky when it comes to the displays they'll allow 3DTV Play to recognize.

A workaround on the MTBS3D Forums and 3D Vision Blog pointed to a possible solution: force the monitor to utilize a driver from an Nvidia-supported model, such as Acer’s HR274H. To our surprise, this trick appeared to give HP’s 2311 gt full 3D Vision support, even without Nvidia's emitter plugged in. Unfortunately, even though our setup passed the built-in driver test, we couldn’t to get it working in a real-world game. The 2311 gt simply reported an out-of-range error.

As a result, we have to consider HP’s 2311 gt an AMD HD3D-only solution when it comes to stereoscopic 3D gaming. This isn’t a big surprise; it's not touted as 3D Vision/3DTV Play-compatible. Nevertheless, we're somewhat disappointed, particularly because limited compatibility narrows the market for HP's monitor.

As far as comparing AMD's HD3D initiative to Nvidia's 3D Vision standard, check our coverage on them both in Nvidia 3D Vision Vs. AMD HD3D: 18 Games, Evaluated and Stereo Shoot-Out: Nvidia's New 3D Vision 2 Vs. AMD's HD3D. To summarize them, both solutions work well, but certain titles are more refined under one solution or the other. So, if you're interested in playing a game on HP's 2311 gt, you might want to cross-reference it with the GameGrade3D database at MTBS3D.com.

    One thing you have to understand that the fact that even 3D models in a game for example get rasterized to a 2D screen. Are they a gimmick then since 3D or 2D graphics, they still end up being 2D anyway? 3D games give us the perception of a 3D world.
    If these technologies can make us have the illusion of having a 3D view, like in real life, then I wouldn't say it's a gimmick. Are (better) in-game graphics a gimmick? A game world is also an illusion of something that isn't there, just like how it seems that you're saying 3D isn't there because it's a 2D screen.
    BTW, it's 2 different frames from different perspectives shown at the same time, just like how your two eyes work. I assume you have two, if not, I apologize.

    If you don't like stereoscopic 3D, then fine, voice out your opinions, but claiming those opinions of yours as facts is just not right. I don't mean to sound angry, but I felt obliged to "voice" this out. I'm open to debate and I don't mean to piss anyone off.

    I forgot if I read this before, but your GPU would have to pump out twice the number of frames for games. As it obviously seems, this is true for active shutter 3D displays. I assume that even if polarized 3D displays "interlace" 2 half resolution frames for 1 3D frame, the processing needed is still for 2 full resolution frames.

    If anyone has better knowledge on this, please correct me. :-)

    Its not worth the price, and if you compare the quality warranty with AOC 23 inch polarized monitor AOC (which has superior color accuracy and 3 years onsite warranty)knock outs this dummy.

    and I liked the acer's 27inch polarized one because it doesn't need a software to convert 2d to 3d.

    what about dual 3D monitors? Do any video cards even support the setup? Would it even be playable?

    I think there's a 3 3D monitor setup possible with Nvidia cards. I'm not sure, but if what I've shared in the first ever comment on this thread is true, driving 1 3D monitor is already like driving 2 standard ones. 3 3D's would be like 6 standards.
    AMD cards can drive an Eyefinity of 6 (standard) monitors, so maybe 3 3D's doesn't sound to bad.
    Again, I'm not sure. Just sharing my observations and deductions on this, and I could be very wrong. :-)

    Dual 3D monitors would be unplayable - The inside screen edges would split your character in half 99% of the time.
    Nvidia supports 3D Surround, which is three identical monitors. I haven't seen it in action, but hear it's fabulous. Pretty sure it requires at least a couple of beefy GPUs running in SLI.

    I can't see why any serious gamer would use a inferior budget screen like this. I mean common, image quality from those $300 or less screens is just complete trash compared to say a good CRT monitor or plasma tv, so why bother? It's nice when your on a budget but if you spend say $1200 on a serious gaming machine then your not gonna couple it with a $300 monitor. It would be very nice if Tomshardware would review some more serious computer screens sometimes in a higher price range of about $800 or something.

    @panzerknacker: Maybe this article isn't just for you. For some people, I bet it is. Some people might not be as picky with image quality (colors, brightness, contrast, etc.) but may still appreciate stereoscopic 3D. It also doesn't have to be gaming, but I'm not saying it can't be. It could be for watching 3D Blu-rays as well. :-)

    "we have to consider HP’s 2311 gt an AMD HD3D-only solution"

    You're forgetting to consider third-party 3d drivers, like iZ3D and Tri-Def

    "BTW, it's 2 different frames from different perspectives shown at the same time, just like how your two eyes work. I assume you have two, if not, I apologize."

    One important difference to consider here: human eyes also focus the lenses based on distance, but with a 3d screen (whether active, passive, or even autostereoscopic like the Nintendo 3DS), one's eye lenses have to focus to the screen distance even when the 3d effect is simulating a different distance.

    Yeah you're right, but what I also try to say is that the last years they almost only review screens like this, cheap ones, and considering this is a website mainly for enthusiasts it would be nice to read about some nicer ones as well!

    If that's the case, I'd agree with you there. Maybe they haven't been receiving test samples? Hehe...

    No thanks to passive 3D. In contrast the similar ASUS VG23AH at least offers an IPS panel vs the HP 2311 gt's TN.

    For a few bucks more look at the still not stellar but better ASUS VG236H (~$330).

    Bottom-line, if I have a monitor for years that I'm going to be staring at -- you're Damned Right it's worth spending the extra cash and getting something easy on the eyes. Otherwise it's like getting cheap shoes that are your only pair and suffering.

    Our previous 3D Vision 2 vs HD3D review compared the newest 3D Vision monitor tech with the newest Samsung tech,. There hasn't been any notable changes to the 120 Hz 3d monitor market since.

    I must admit to being a bit prejudiced against FPR technology, for the simple reason I want higher refresh rates more than I want 3D, and FPR does nothing to support 120Hz refresh rates.

    Of course for 3D shutter technology, I really want 240Hz (minimum) :) .

    soldier37Tired of seeing these cheap 1080p displays being churned out week to week. Where are the LED 30 inch 2560 x 1600 models at to replace my current LCD model? Get with the program guys. Once you go that size you wont ever want to do 1080p again.


    I mostly agree. I went back to 1080p because my XHD3000 was outputting too much heat into my room, but an LED monitor with that resolution probably wouldn't be so bad. I'm somewhat regretting the 32 inch TV with passive 3d I recently bought (I had underestimated the issues with text based on TFT Central's article that discussed 3d display types :( ), but I seriously doubt the warranty would let me return it just because I want a higher-resolution monitor. Setting aside obscure South Korean brands like Yamakasi and Achieva, I think the newest super-high-resolution monitor is the Apple Thunderbolt display, but that was released on July 20, 2011, making it almost a year old. Some of the other models are harder to find release dates for, but I think they were 2010 or older.
