Verified Purchase
I was almost ready to buy a GTX 460, a Nvidia 3D vision kit, and the Asus 23.6" 120HZ 3d monitor. This would have totaled to $640, ($490 if you have the proper card already). The Asus wasn't even back-lit LED.

Instead at the last minute I saw this, strangely without any reviews. I looked more into it, and apparently it was a new release, and some review on Newegg said the 3d looks impressive, so I took the risk and went ahead. Total cost $300 (the price seems to fluctuating up and down). The biggest con is there just isn't so much information about it online. The funny thing is, I still don't know some important details, which I will go into.


Hands down, the cheapest way to get into 3d gaming, 3dwise the value doesn't get any better than this

The 3D Looks GOOD, no flickering

LED Backlit saves energy

1080p resolution, cinema aspect ratio (i.e. no bars on Hulu)

Comes with TRI-Def (3d conversion software for games and viewing photos/videos)

Cheap Polarized Lenses, and NOT tied to Nvidia Graphics Card to keep 3d


2d wise, it is a typical run of the mill screen, blacks are disappointing, there is minor backlight bleeding, definitely doesn't have that WOW feel some displays have, did I mention the blacks were disappointing?

I can't find too much information about it. The 3d solution is TriDEF, (The same software AMD 3D uses) BUT, AMD does not list this as a compatible display. If you go to the downloads section on
Tri-Def, the LG is a separate download. I installed the "generic" TriDEF software and it did not work with the display. How much modification does TriDef do for the LG display? Is this a "standardized" 3d display that will continue to have updates?

UPDATE: I changed my review from 3 stars to 1 because after 1.5 years of fairly light usage, this monitor no longer functions. Now when it is turned on, it's own built-in logo and 'check cable' displays roll and flicker. Connecting a computer (any input) and displaying an image results in the same problem. At some point I'll take this apart and see if I can fix it but don't hold out much hope. Perhaps if I used it more it would have failed during the 1 year warranty.

This is a very long review, so let me bring an import issue up front. This monitor comes with 1 pair of glasses and 1 pair of clip-ons, and as of the date of this review (early Fall 2011) you cannot buy more of these same glasses, at least not from any major retailer like Amazon, nor as a replacement part from LG. When contacted about this, LG Customer Service has told me and other LG monitor owners to buy the replacement LG TV glasses instead. But they are not compatible with this monitor. More details about this below.

* Summary:

The LG D2342 is a competent 3D computer monitor that uses passive glasses technology to display stereographic images. With appropriately processed JPEG files, it is possible to display 3D still images on this monitor using a non-Windows computer (Mac, Linux, etc.) because specialized hardware driver software is not required. This monitor is also the perfect companion for use with the free StereoPhoto Maker application for editing and displaying 3D photographs that are encoded in virtually any common digital 3D photo format. It also gives the Fujifilm W1 & W3 camera owner a quick, convenient, and fun way to review and show off 3D photos and videos straight from the camera.

This monitor has a very bright screen with what I would judge are pleasing color renditions. Other reviewers have rated it average for rendition, but compared to my old monitor it was good. I bought the monitor primarily because it was an inexpensive way to get 3D, and as such it certainly is one of the least expensive 3D options. It works just fine with my AMD processor and built in GeForce 9100 video processor.

I tried both the included 3D glasses and ReadlD 3D glasses and both appeared to work. But the RealD glasses produced much more ghosting. The 3D essentially reduces the vertical resolution from 1080 to 540 pixels. This produces obvious black lines when viewing with 3D glasses. In addition very small 2D text is not very readable. Non 3D text on the icons looks indistinct and hazy. It is possible to sit back far enough to get rid of the black lines, but then you may be too far to use the keyboard easily. The black lines and low resolution were not visible to my spouse, so it would depend on the viewer's sharpness of vision. I have 20/10 vision with my glasses, but even with them off I notice the black lines. The resolution reduction does not seem to be a problem with 3D pictures or movies, but mainly shows up with 2D small text.

I have a large number of Realist 3D slides that I have scanned, and they look very good but there is some ghosting. I first bought this monitor and found the ghosting to be unacceptable so I returned it. But when my regular monitor died I bought it again and this time with the LG included glasses the ghosting was usually unobvious. But very bright objects against a dark background such as ceiling lights tend to produce ghosting.
