LG D2342P-PN 23-Inch Widescreen Passive 3D LED LCD Monitor





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 about equally as well. The 3D essentially reduces the vertical resolution from 1080 to 540 pixels. The produces obvious black lines when viewing with 3D glasses. In addition small text is not very readable. Non 3D text on the icons looks indistinct and hazy. It is possible to set back far enough to get rid of the black lines, but then you are getting both reduced vertical and horizontal resolution. 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.

I have a large number of 3D pictures taken with my Fuji 3D camera and also scanned 3D slides dating back to the 1950s. So I was able to compare a number of pictures iusing the free "Stereo Photo Maker" in interlaced mode. Some looked good, but with dimished resolution, while others had ghosting. The ghosting was often critically dependent on the vertical position of your head and at some positions it was possible to remove it on some slides. But some had ghosting both at the top and bottom which could not be removed. Sometimes it could be minimized by viewing the slides close to the monitor, but often one set of ghosts could only be removed at the expense of making the others worse. I do have a side by side 720P 3D movie which was not too bad when viewed at a distance from the screen. The motion apparently mad the ghosting less obvious and more tolerable. I also used the TriDef 3D viewer which came with the montor, but it didn't seem to do a better job.

Formats are not well standardized so I was not able to properly play the native Fuji movie AVI format. When played through TriDef it was only 2D, and when played through 3D Movie Maker the picture was in 3D, but I had no sound. Slides in either side by side or the native Fuji MPO formal could be played adequately.

So while the monitor certainly does provide 3D reproduction at a very modest price, the downside is the reproduction with ghosting. My spouse did not seem to mind the ghosting as much as I did, so this problem may be tolerable to some users. I would recommend buying it with satisfaction guaranteed return priveleges. Since it works without a special graphics board, and the glasses are lightweight as well as inexpensive, some users may be willing to tolerage the defects. The Samsung passive monitor is due to be released in 2012 and it promises full resolution. It may be well to wait for that monitor, but since the technology is more complicated it will probably be higher priced. But it will still have the advantages of the lightweight glasses without the need for an expensive add on graphics board. I find that my old Realist slides still give the best 3D reproduction compared to the LG monitor. Not only is the depth superb, but figures have natural rounding and do not look flat unlike the digital reproduction.

Asus PA246Q - LCD display - TFT - 24.1 inch


Just picked up one of these bad boys and so far I'm impressed.

Note on shipping: though the shipping estimate said I would get it in about 7 days with Prime (weird?), it came next day, about 24 hours after I clicked purchase. You have to love Amazon.

Versus Other Displays: As an amateur in the color space world, I'm still getting used to the colors vs my other Asus monitors. I'm having a hard time getting all three monitors to play nice together, but I think that mainly has to do with the low quality of my other two 25" ASUS displays. I purchased a Spyder3 Express monitor calibration device and now at least all of the white balances are the same across the three monitors, but the PA246Q is clearly of much better quality.

As far the monitor by itself, it's pretty amazing. The settings that it comes with are deep and the colors that it can display are breath taking. I have yet to do any really heavy lifting with it, just mostly Photoshop, Lightroom and regular web usage. It might just be me, but the AdobeRGB profile looks really red... but again I'm still learning how to set everything up. I'm sure someone a lot more experienced than me will have thoughts on that.

UPDATE (3/2/2011): I calibrated everything correctly (thanks to some Google searching), embedded the color profile to some photos, and sent them off to be processed. Result? Almost perfect 1:1 representation of what I saw on the screen to what I got back from the printer. Was just a tad darker in the print than the screen, but I would think that has to do with the printer. Tickle me impressed.

Cons: As far as I can tell right now, the only con for this monitor is the price. There is a Dell 24" with IPS that sells for about $30 less or so. Also, though the monitor is almost silent, it does give off a fair amount of heat. But to be honest, you should expect that from any 24" monitor.

Conclusion: So far I'm really happy. In a perfect world I would be rolling with three of these babies and not just one in the middle of a three monitor set up.
