M1F193是啥？

Just so some of you know, there've been reports of Dell sending out firmware revision A02 U2410's, with a version number of M1F193, in the last 2 to 3 weeks. As well as a report on HardOCP, someone posted this on an Italian forum..

Supposedly it might contain some improvements specifically relating to video input and better translation of 24 FPS HD content, but there's no firm evidence yet for what the changes might actually be.

Btw - If you get an A02 screen right now that's not necessarily a good sign. Dell often start out by flashing refurbed screens first. So, if you got an A02 screen, it might well be a returned A01 flashed to A02. Shipping screens directly from the factory containing A02 seems to happen some weeks later. In other words, if I got an A02 right now (particularly one with a sticker placed over the original A01 writing!) I'd hope it wasn't a refurb of someone elses problem screen.

I don't think it fixes the 2 main things requiring improvement on the U2410 anyway. The first is that you can run in Game Mode with sRGB/Adobe mode colours by switching from Game Mode to those colour modes without confirming. It appears to change the colours whilst keeping the responsiveness of Game Mode as long as you don't confirm the change in the menu. So it'd be nice if they'd directly add some menu support so people can finally run things like an sRGB Game Mode without this kludge work around required right now to enable it.

The second is a more major change. The colour LUT (Look Up Table) seems like it's only being used correctly from sRGB and Adobe Mode. In Custom Mode you cannot adjust Hue controls below 48 or above 52 without introducing nasty banding artifacts to colours. So Custom Mode doesn't appear to be making any use of the LUT, and thus the range of colour tweaks you can apply (before introducing nasty visual problems) is extremely limited. Worse, the default gamma value in Custom Mode seems to be somewhere between 1.8 and 2.0, which means it's effectively impossible to get accurate colours out of Custom Mode with a gamma value of 2.2. Many users won't really notice they're using a gamma of 2.0. But, for image pros and people who care about colour accuracy and 2.2 gamma etc, they'd probably find Custom Mode unacceptable for this reason. Hopefully Dell will get around to fixing this some day, or at least endorsing some sort of calibration software which gives direct access to the U2410's LUT etc.

As for tint issues, as other have said, the only way for it to be fixed would be for LG to refine their panel production process. It appears to affect all current LG made IPS screens to some extent. In the U2410's case it's probably reported more often because the wide gamut back light makes reds more red and greens more green etc, which means any colour gradation/uniformity problems present also stand out more. It's perhaps further emphasized by the choice of anti-glare coating too. Short of spending a lot of money on a higher end NEC or Eizo screen (with corrective controls for these problems) there's nothing that can be done other than swapping screens until you get one which doesn't have the issue to any noteable degree. Even in the NEC/Eizo case it's not ideal since any screen "corrected" for tint problems would have less contrast than a screen without the issue. The real problem is only a few companies hold the rights to manufacture IPS panels and LG appear to "completely **" at making large uniform panels for the computer screen market at reasonable cost.

In the U2410's case it's a great screen, so it's worth persevering if you get a dud, although I would also look at the cheaper HP HP ZR24W now too..
