Samsung LCD LTM213U4-L01 Panel

The Samsung 21.3" LCD panel in the 213T has been around for some time. The actual introduction of the panel occurred back in October of 2002. However, that does not make it any less capable than other panels we have seen. The LTM213U4-L01 design is comparable to other LCD designs we have seen in smaller sizes; 2x3 CCFT backlights, 85 degree universal viewing angle, 8-bit (16.7M) color replication.

We have mentioned some other display modes in the past. AUO's modified TN mode powered the Hitachi CML174 LCD with a 16ms TrTf response time. The Dell 2001FP uses an LG Philips LCD based on an IPS derivative. Samsung's PVA, Pattern Vertical Alignment, is a derivative of the VA display mode.

For those a little more interested in the panel, we highly recommend checking out the panel datasheet which has plenty of very specific test procedures and specifications. Any aspiring electrical drafters are encouraged to check out page 22.

Our only real complaint about this panel is the start up time. Granted, the start up time does not typically come to mind as a critical purchasing decision. However, do consider whenever the monitor goes on standby, the panel completely powers down. This was an enormous annoyance to us in the lab as we constantly were waiting for the monitor to power up after going on standby.

Screen uniformity was very good. Occasionally we could spot the backlights through the TFT. We do not expect that most people would notice the difference; particularly if the screen is not a full solid dark color.

    Great review, but my question is how the hell did you get the picture on the first page (with the display that has anandtech.com on it) to show the review already online? :-D

    I bought a Dell 2001FP. It was nice and crisp, but the textured appearance of solid color areas was quite distracting. It would not reliably sync to the various text modes passed through during boot. Worst, it FLICKERED in a kind of checkerboard pixel pattern when things moved, as if it was really an 18-bit panel and was using a 2x2 pixel dither pattern.

    Either I got a dud, or AT's model had a different panel to mine. Not sure which. I sent mine back and got a CRT. (Not fond of Dell tech support either.)

    I've been using a 213T for about 2 months now and it is a fantastic display, absolutely worth every penny of its price!

    I run mine on the DVI output of a Radeon 9600, and the picture is simply stunning. Also, my panel has zero pixel defects, which is amazing considering there are almost 6 million subpixel elements.

    wizardsinc: Sapphire makes a bunch of dual DVI AGP cards - you might have to special order them but they are totally worth it. As of November I heard that dual DVI accounted for less than 1% of graphics card sales.

    I just thought I'd post an update: A friend of mine just bought a Dell 2001FP, so I was finally able to compare the Dell & Samsung 213T side-by-side. I'd have to say that I agree 100% with Kristopher: The Dell is absolutely beautiful, but the Samsung sitting next to it looks even better. The main differences I could see (besides the obvious physical size differences) were: (a) The Samsung was softer on the eyes and appeared brighter and "whiter". (b) The lines between pixels on the Dell were much more obvious than on the Samsung - when sitting side-by-side, the Dell looked like I was seeing the image through a small screen mesh (very crisp). The Samsung has nicely defined pixel bounderies, but the line between pixels is not as apparent. (c) In Dell's favor - the 16ms vs 25ms refresh rate difference was noticable. Small fast-moving images would fade slightly on the Samsung, where they would remain intact on the Dell. All-in-all though, I decided that for my purposes, the Samsung was the winner. There is currently a $100 mail-in rebate on the Samsung, bringing the price down to $1100 at Best-Buy, so I picked up a couple of them. I've already set them up and I must say they're awesome running side-by-side! :-) Now I have to upgrade to a video card that supplies two DVI outputs (I'm currently running 1 DVI & 1 VGA). Any suggestions? I'm under the impression that Nvidia might be a better choice over ATI, but I could be wrong. Again, any suggestions are welcome!

    Thanks to all of you for aiding me in my display purchase decision. It's great when discussion groups work. ;-)

    TauRusIL: Interestingly enough, samsung makes a majority of the components including panels. One of the reasons we look at so many Samsung LCDs is just because they typically sell the panels to several other mainstream OEMs.

    You don't need a hack to make XP run at 640x480 (or to use a 256-colour mode at any resolution either). Just press the 'Advanced' button and select the Adapter tab, then press 'List All Modes...' button and you'll find the hidden modes listed and selectable.

    Vey useful for some older games which won't run full-screen unless started from 640x480, and a few which won't run at all if not in a 256-colour mode.

    I noticed most of the LCD panels reviewed here are made by Samsung. I wonder if there were any plans to include LCDs from other manufacturers.
    I am a long time and very happy user of Princeton SenErgy line of LCDs. To my eyes, the picrure quality of Princeton Senergy line is way above most of other LCD panels. Of course this is a subjective view.
    I would love to see a comparative review of the Princeton Senergy and lets say Samsung or Dell panels.
    On the side note: does anyone know who is the OEM for Princeton line of LCD panels, or do they make their own panels?

    Great review. I'd like to see more of the "subjective analysis" in the hardware reviews at AT (as long as it's labeled as such, of course). Hard numbers can omit many truths about a product's actual performance.
