Might be a thunderbold vs. displayport spec version # issue..?

i've the same suspision. U2410 i've is 2009 - the first version rev.00
Possibly the new revision that DELL makes i believe is 04 or 05. it might be the DP version as you mentioned.
stores around here don't have U2410 on display for me to confirm.
There appears to be an A01 user flashable firmware floating around. I am tempted to try it, but haven't been able to track it down yet.
EDIT: I applied the update, and it still doesn't work because the Mac still thinks the monitor is a TV. Oh well.

Looks almost like a form of sharpening is being applied, from the sort of 'halo' the letters have. Could be worth checking the sharpening setting on the monitor.
Otherwise Dells and OS X have been known not to communicate things perfectly. Is there any pinstriping on shades of grey?

the issue is the MBP thinks is a TV - and therefore sending the signal in a different way then to a display. read the history...
Having an issue with my 17" 2011 and a lp2475w too , with a mini display port to hdmi adapter .
It just feels like it's not in native resolution , kindda like setting resolution of that monitor to 800x600 .
Tried it with a mbp 13" from 2010 and looked good using same adapter so kindda worried ;o

Having the exact same problem with my 2011 15" MBPro. I'm pushing out to a Dell U2410 via a mini displayport to displayport cable but the Dell monitor seems to be recognized as a television so although it gives the option for 1920x1200 resolution, it still pretty much looks like a crappy 1080p HDMI signal but on a nice monitor.
I'm definitely updated to 10.6.7 OSX and not sure which firmware I have on my U2410 but I think it's A01.
I've never really dealt with Apple support as I'm an IT Admin and fix things on my own, but this one definitely needs to be reported to them. What's the best way to go about this?

call and complain as others did. perhaps try to speak to an engineer. however i believe they must KNOW about this problem already.
I just got a 2011 2.3GHz 15" this week, replacing a 3/2009 MBP 2.66. Both connected to one of my Dell 2408WFP monitors via a monoprice mini DP-DP cable. Image is perfectly fine, as it was on the old one.
Have you been able to test your rig on a different monitor?

My macbook pro 17" 2011 was having issues with a mini displayport to hdmi since it was detecting my monitor as a tv , i bought a mini dp to dvi and now everything works great .
Cheers
The same mini display port to hdmi cable worked fine on the same monitor with a 2010 mbp 13" , but i guess it's down to the graphics card and detecting the monitor in a different way ?
Anyway the mini displayport to dvi solved the issue for me , and if i connect my macbook pro with the hdmi cable to my actual tv it also looks good so it's not something specific with using hdmi either , just detecting monitor in the wrong way .
Hope this can help someone , cheers

This points to a specific problem with the U2410. Interesting.
Although we know that it's definitely a software problem.
Yes it's clearly a U2410 problem with Macbook Pros using displayport. I would have gotten a miniDP to DVI cable but opted for the less bulky, very minimalist displayport cable and I don't feel like sending it back to monoprice. It should just work as designed.
This should be a fixable problem with a patch or updated drivers for the video card so hopefully Apple is working on it.

I picked up a dvi to mDP cable over the weekend. Not as good as the mDP to DP cable, but better than the the mDP to dvi adaptor.
I would switch to a mDP to DVI cable but my PRO laptop should be able to handle mDP to DP with no issues.
Is Apple usually this slow in fixing these things? In the PC world I could just get a new video driver from the video card manufacturers website. Why do we have to wait on Apple to fix this?

It's possible....
that the problem is related to what's called "HDMI handshake." There is something undeveloped in the (hard/soft) ware of Apple's machines and their relationship with High-Def capable displays. It's probably the reason they are holding back on blu-ray.
I'd start by eliminating the use of third party cables. I have even noticed similar issues with older portables and hi-def displays.

There are a lot of cheap crappy non-spec Displayport and other cables out there. I've had very good experiences with Kanex. Their cables also eliminate the bulky box and give you everything in one cable.

Display port problems are not unusual on PC's either.

Brand-new 15" 2.2GHz MBP with a Dell U2410 (A01) and a Mini-DP -> DP cable has this issue. Painful given that the damn thing is supposed to replace my desktop so will be docked most of the time.
Monitor is detected as a TV, and changing the colour mode from YPbPr in the monitor menu to RGB fixes the ghosting and haloing, but obviously the colour is then off. Looks like a driver/firmware issue to me. U2410 was fine with my previous 2009 15" over DP.
I should complain to Apple, but realistically they'll presumably fix it in time. I wonder if they'll refund the mini-DP to DVI adaptor i'm now obliged to buy when they do?

Go to your local Apple Store/ Reseller and explain the issue. ask if you could borrow a dvi cable to test the issue. show that it works, now if apple ask if you can have the cable until a fixed is realised, if reseller ask wether they think apple will provide a cable until its fixed. Should end up with you having the adaptor

Heh heh, thats pretty much the plan for tomorrow!
I just connected my new 13 mbp to my A04 U2410 via mdp-->hdmi and everything looks good. I got the cable from monoprice. I have the mbp set to mirror display, the resolution set to 1920x1200 for the external monitor, but it does show the U2410 as a 60hz NTSC TV.
I reread some of the earlier post and now that I think about it, the display is clear without ghosting, but it does look like a 1080p signal feeding a tv. My Dell XPS is connected to the same U2410 via DP and it looks nice and sharp at 1920x1200. I'll have to try a mdp-->dvi cable to compare.
