Conclusion: A Good 16:10 IPS Display

After using it, the Dell U2412M comes out with a lot of positives and no big negatives. The screen has a nice 16:10 aspect ratio that makes it feel roomier than a normal 16:9 display, and it has a nice adjustable stand that made it easy to fit on my desk. The contrast ratio was good, power use was low, and the response time for gaming was also very good. The overall dE values were acceptable but not fantastic, and the screen was relatively uniform.

The main negatives I can come out with are that the dE values get slightly high for blues, but they do that on any monitor that doesn’t display the full AdobeRGB colorspace. Similarly the frame lag numbers look bad in comparison to other displays, but this is our first attempt with a new testing method and I made sure to select the worst-case scenario numbers as well. I can criticize the black uniformity as the corners were a bit bad, though being a lot better in this area will likely require using something other than the current edge-lit LED system or the emergence of OLED displays for the desktop, which would definitely increase the cost (by a large amount in the case of OLED).

In the end, would I buy the Dell U2412M for myself? Yes, I probably would. The fact that you can find it for $300 or less on sale fairly often and that it calibrates to a decent dE value makes it easy for someone to use as a general-purpose desktop display. Viewing angles are good, I still like the adjustability of the Dell stand, and the larger work area made for a good combination.

The closest competitor seems to be the HP ZR24w, which features an S-IPS panel but otherwise looks remarkably similar. I haven’t had a chance to see that in person so I can’t elaborate further, but that was the only 16:10, IPS panel at Newegg that came within $75 of the U2412M. I really think Dell has taken everything out of the display that they can (e.g. reduced to a 6-bit panel, no LUT, no HDMI) to produce a panel that is affordable but still very good for most people, and far beyond the 16:9 TN panels that many people might be upgrading from. It’s certainly not perfect, but it’s good enough for most people, and it is what I would want as a bare minimum if I was in the market for a 24” monitor.

    Honestly, if I had to chose between 16:9 with 1080p or 16:10 with 900p, I'd take 16:9. The real issue people argue is that the 24" market has gone 16:9 with 1080p. No gamer or other user would go with anything below 22" unless there are space constraints.

    The U2410 is not a budget screen by any measure, though, and although it is "old", it is not actually old. It is still being sold alongside the U2412, because the U2410 has a true 8-bit S-IPS panel, 10-bit processing, wider gamut (almost all of AdobeRGB) and a slew of inputs.

    It's still relevant.

    Dude, nobody cares about your low resolution 16:10 screens.

    Only very strange aspect ratio freaks think 1440x900 is better than 1920x1080 anyway.

    It's cool to see a budget 1920x1200 monitor out there.

    The direct competitor to reviewed Dell monitor is HP ZR2440w 24-inch LED Backlit IPS Monitor, not ZR24 - its the previous generation.

    PS: Dell isnt the LCD panel maker - its LG, probably model LM240WU8.

    The HP is a tad bit more expensive but a much better deal with much better service. I'm surprised the author didn't know this was actually the competitor for this Dell not the old HP monitor.

    For competitors I was specifically search for other IPS/VA panels with 1920x1200 resolution that were within $75 (or 25%) of the price of the Dell. The only model that came up at the time of searching was the older HP, which is why it was listed. There are a lot of other 16:10 IPS/VA panels, but once you got past being within 25% of the price, I didn't consider them direct competitors anymore.

    U2412M and ZR2440w are direct competitors from hardware point of view (LCD panel) but the price is really better in Dell case.
    In Slovakia, its 253€ for Dell and 350€ for HP, both have 36 months On-site warranty. The question is - why is HP so expensive? I guess there must be something cheaper used in Dell monitor (power circuit, controller board, ...). Who is OEM of the Dell? ZR24w and ZR2440w are made by Tatung.

    Wait, what makes the HP a "much better deal"? I'd call service of HP and Dell monitors pretty close to equal, and the HP is $50 more for the lowest price I can find. 15% more is only "a bit more"? They're both eIPS AFAICT, so other than the nebulous "service and support" aspect, why would one be better than the other?

    HP has more inputs, a scaler for 1:1, thus can be hooked up to consoles, and better RTC control. The latter makes it a bit more responsive, but former to have higher input lag. Comparing several reviews, HP tends to have better uniformity.
