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:

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.

    Bloody; With a passive 1080p monitor, ¿can i play @1080p in S3D?

    Don’t know what you mean exactly but yes you “can” only when sd3 is activated you’ll get half the resolution per eye. Passive technology inherently has to split the available resolution to half per eye in order to work. It’s very much like Nintendo’s 3DS that uses a parallax barrier to do the glasses work. There the 800 pixel horizontal resolution of the screen gets cut into 400 per eye once 3d is activated. It’s okay for the little screen on the 3DS but it sure as hell isn’t for a desktop sized screen IMO. The lower resolution is very visible.
