In Japan atleast..

Well, Mitsubishi's got you covered with its new 23-inch LED backlit IPS panel that promises Full HD resolution, 178-degree viewing angles, and a 3.8 millisecond response time from a 39 millimeter-thick slab of screen. Content comes to the RDT233WX-3D through a DVI-D connector, two HDMI 1.4 ports, and D5 connections, while your eyeballs see things in three dee with the included passive 3D glasses. It'll be available on May 30 in the Land of the Rising Sun (no word if it'll come across the Pacific) for an undisclosed amount.

With the description of Full HD, I'd assume so. But damn, this sounds awesome. It even includes glasses. I bet it costs a small fortune.

Most definitely! It uses polarization for the 3d effect. I'm pretty sure that means it has two screens in it. The glasses dirt cheap polarized plastic lenses. I just hope the 120Hz is actually real and not just because the two screens are each doing 60Hz.

When you can get a crappy TN 23" for $150 and an IPS for $200-220, idk...I'd think $400 might be reasonable, $600 is too high IMO.

Obviously.. it will be a little high as this is basically the first of its kind. A decent 23" 120 Hz TN panel cost's $400.
 
Point me to the bit of the specs that say its 120hz?

(remember it says glasses are passive - so don't require 120hz).

120hz 23 inch TN for 150?

you serious? link?

as far as i know they all start at 270+ for TN! with 120hz.

600 sounds right considering viewsonics 3d TN is roughly almost 400.

computer monitors + 3d = implied 120hz..

this aint a HDTV.

No, you can do 3d without 120hz. 120hz is required for active 3d shutter glasses, this uses passive 3d glasses. It also doesn't mention 120hz anywhere that I can see, which it would if it were 120hz.
 
$600 is a very good price, IMHO. People who are happy with TNs will find even +$100 as too much. 🙂

You are right, I'll edit the title.. here is a detailed description of the product translated from the original article.

Oh crap you're right, my mistake. I was looking for 120hz screens but I pulled up 60hz screens. I'll edit my posts.

It's definitely not 120Hz (at least not on the input side).

Some background: with passive 3D systems, they use a polarization filter to separate pixels on a row by row basis. Half the row go to the left eye, half the rows to the right eye.

The end result is that both eyes are always seeing something, as opposed to an eye being blocked out at all times with active shutter glasses. At the same time because both eyes are seeing something, there's no need to display images at more than 60Hz (120Hz is necessary for active because each eye got half of that). Finally, because it's a passive polarized system, the vertical resolution is halved since you're splitting 1080 rows between two eyes. So what you're actually seeing is 1920x540, or half-resolution 3D, which is a notable deficiency compared to active systems which at least give you the full resolution.

In any case, nothing about this system requires 120Hz operation. With HDMI the input is frame-packed 720P60 or 1080P24; I'd imagine DVI is the same using DVI-DL. The output of course is no higher than 60Hz.

Ultimately it's not a computer monitor in the traditional sense, it's a TV that can be plugged into a computer. This is not the 120Hz IPS monitor we have been looking for...

TL;DR: It's a 60hz 1080P IPS panel with a polarizer in front of it and a suitable controller behind it to handle frame-packed 3D

Yeah, I don't think IPS can do 120Hz, the technology just cannot refresh that fast. At least not right now.

I believe the new PLS should be able to do it, so that'll likely be where we'll quality with 120Hz. Its possible we might see an IPS, but the overdrive would have to be really aggressive, and so it wouldn't be something you could use all the time (plus who knows how long the monitor would last if you were constantly pumping voltage through it).

On a side note, does anyone know what IPS monitors can do 72Hz? I'm wanting a monitor that can do smooth Blu-ray playback.

Is this spec sheet is true, then still no 120hz guys/ gals - http://www.mitsubishielectric.co.jp/news/2011/pdf/0427-b.pdf

The NEC EA231WMi (which has been out for awhile) can be a viable alternative. I'm getting a solid 83hz (via DP) with no dropped frames. Night and day difference, coming from 60hz. Very slight ghosting (if you're looking for it), but its excellent input lag (or lackof) more than makes up for it, especially in twitch shooters.
