I use a pair of 2408wfp's at work which are great too, awesome stands. I just got a pair of these new 2412M's also, and set one up to test yesterday. I also noticed the huge blueshift which was driving me crazy, I couldnt get the screen configured the way I like. Otherwise, they are nice and light, and the stand is decent.

I used the settings found in this review:

Dell U2412M review - FlatpanelsHD

Seems to have helped a bit.

I used 10e's settings (I am fairly certain he posts here as well) that I saw on a different forum. They are fairly similar to the flatpanelshd review.

How would you say this monitor compares to the 2209WA? Probably pretty similar?

The WA2209 has no issues with ghosting and the like, the stats sheet says it is a 6ms GtG. Colours should be similar in performance, since the 2209 is a e-IPS screen as well.

The real advantage the 2209 has over the 2412 is the 75hz refresh rate for "moar fps!"

How was the calibrated setting determine? I can't seem to find it in the review.

What would be a good calibrated tool to buy?

Yup, sure do. Mostly folding here, so we can dominate in the Chimp Challenge yearly

Just missed the get together in T.O. this October due to the birth of a new 7lbs. folder!

I consider it the next step to the 2209WA. Low input lag, but a little bit worse overdrive causing some reverse ghosting. I play games often on it, and it doesn't bother me, and it's hard for me to pick up even when looking at it.

More reverse ghosting on the U2412M. I was able to get into the service menu and shut off the overdrive, as well as adjust it lower for different results. It has an on/off toggle and goes up and down from a level of 55 (going from memory).

The problem with the original batch of 2209WAs (which I had in Jan 2009) was that they often had a blue to red tint on whites going across the screen. This is tough to calibrate.

Spyder3 Pro is probably a great software/hardware combination, which seems to work well for wide as well as sRGB gamut.

Yeah, I have to ask too. These settings/results seem absolutely WAY OFF

Lowest contrast of an IPS panel? Everyone is getting minimally 750:1 contrast after calibration and I was getting 1100:1 before calibrating !!!!!!!!!!!!!!!!11 This was with my NEC tuned X-Rite I1D2 sensors, but I am waiting for my favorite program to support my new Eye One Display 3/Pro to get even better results.

I have to re-read the review to see what the testing equipment was, but it seems like a different screen than what I got. Default settings were 1100:1 or higher at all brightness levels, and gamma was in the 2.1 range for me at 75 contrast (default).

Here's what I got before I started calibrating (for contrast ratio):



This is with the standard color preset.

For those concerned about a dominant blue (typical of W-LED back-lit screens it seems), try using the "Color Temp" preset with "5700K" selected.

I found this to be a very nice setting. It's sitting next to a well-calibrated screen costing three times as much and it's looking fairly similar.

You mention Spyder which is a $200 piece of software. At the risk of sounding cheap I have to ask if you know of anything more affordable that bridges the gap between professional and free (useless).

The numbers that I got for contrast are the numbers I got for contrast. Confirmed it via Spder's built in suite and using ColorHCFR. Both were taken from the center of the screen and both programs came back with the same results.

They were indeed lower than what every other IPS monitor we have tested has given. YMMV but that is what we got and it lines up with my own judgment when compared against the others I have tested (ie its most likely a 6 bit panel going up against 8 bit panels). The 2412 is very good entry level IPS panel, but it can not compete against the 2410 (which by your numbers would place the 2412 ahead of the 2410). This is why the difference in pricing and why the 2410 will be sold alongside the 2412.

You can pickup the basic Spyder 3 Express. The only difference betwen the various Spyder 3s's (IIRC) is the software. Should be able to pick one up for about 90 usd or so. Assuming you dont want to do anything fancy and just want to CLAIBRATE your monitor that is. If you want to get more fancy (and dont mind a bit of a learning curve) you could use the open source ColorHCFR program + Spyder 3 Express to tweak things to perfection. But honestly, the basic express software kit by itself will tweak things darn close.

I understand, but what I'm saying is either those numbers were received from a bad unit, or with a bad colorimeter, or with a bad setting. Something's up. If there weren't established reviews I'd probably say the numbers I got back in August were bad, or I somehow bought the cherrypicked golden sample.

Spyder3 sensors are not known to be the most accurate at measuring black levels, so being a bit off is normal, but PC Monitors | Computer Monitors got over 700:1 contrast and they also use Spyder3 sensor.

TFTCentral got over 1000:1 contrast, as did I, and Prad got over 800:1. Maybe you measured it in video mode, as Prad got a similar contrast number in Video mode, somewhere around 540:1.

I was asking about your equipment because an I1 Pro Spectrophotometer would give similar results, as they can't often detect black levels below 0.3 cdm/2, so I wanted to be sure why the contrast numbers are so low.

It should have nothing to do with the 6-bit+AFrc panel used in the U2412M vs. the 8-bit+AFrc panel in the Asus PA246Q and Dell U2410. This affects colors and gradations more than absolute black versus absolute white, or RGB levels of 0,0,0 versus 255,255,255.

In my comments I'm not comparing the U2410/Asus PA246Q with a U2412M. They have different targets, mostly those who need wide gamut and the associated high-bit panel and high-bit color lookup table required to use these in a calibrated color-managed workflow with minimal color losses.

And to be honest, the U2410 and PA246Q are not known as being contrast ratio champs. In fact they are definitely considered on the low-end of the scale, so your numbers for those two screens are in-line with what I've seen elsewhere.

The U2412M doesn't aspire to that target. It is an office-type monitor with low input lag and rudimentary scaling capabilities (ie. no 16:9 mode supported from HDMI type sources). This all makes it a good gaming screen. Less lag due to less image processing/buffering

There is a fair bit in this review I agree with in terms of the U2412M, including slightly reduced viewing angles, and the resulting very slight color shifts up close, slightly aggressive RTC/overdrive, etc... I also have a slight preference visually with CCFL back-lighting where the whites seem a tiny bit warmer and have less blue push.

Oh, and here is my post over on [H]ardforum with the service menu combo to access the overdrive setting:
