I know it happens on the old ATI X1600's... I suppose we'll have to wait for community feedback regarding their modern GPUs.
 
Using a MacBook Pro 13" 2010 (nVidia 320m) with a Dell U2311H connected with a DisplayPort cable.

I also had the dithering issue here with shades of gray and gradients. I installed the NVinject extension and the problem is gone!

The only thing is that NVinject is a 32bit extension and unfortunately won't work with the 64bit kernel. Is there a 64bit version of NVinject?

I wonder if Apple will do anything about this...

i hope the next mac mini does not have this issue. I have the U2211h display and had no problems when I hooked it up to a core i3 imac via miniDP....
 
Just FYI (for Googlers?) I did take the plunge and switched to a Radeon 6850. No injection hacks required as there's no pinstriping (and none of the aforementioned text rendering issues) out of the box.. it works flawlessly with the U2311H. AWESOME :D

Interesting thing of note, the NVidia cards keep the aspect ratio of 1024x768 output with black borders either side and sometimes add black borders to the top and bottom.. the AMD/ATI ones fill the screen. Think I prefer the latter despite it messing up the aspect ratio. YMMV.

Those upgrading a Hackintosh with a Radeon 6xxx right now will need to be ready to be fairly experimental and do some reading, but TBH that goes for the whole Hackintosh thing in the first place. Tonymacx86 is good.
 
Hi

Does anyone have any experience of using a U2211h / U2311h with an old MacBook with mini-DVI and Intel GMA 950 graphics?

On paper, the U2211h would seem to fit the bill perfectly for what we need (U2311h would be okay too, but we're constrained for space). But, the issues in this thread concern me. It looks like there's been some fantastic troubleshooting and hacking going on with the kexts, but would any of this help with a lowly Intel graphics chip?

The MacBook in question is my wife's. It's a 2006 1.83 C2D with 2GB RAM and Snow Leopard (10.6.7). It mostly just gets used for web and MS Office.

Cheers

The Intel GMA 950 should work perfectly fine with these monitors, as the GPU does not support temporal dithering (the likely source of the problems described in this thread). A while back, I hooked up my u2211h to my 950-powered MacBook and ran it through my tests, and never saw any problems.

To be honest, I've not seen any pinstriping problems with my nvidia 320m-powered Mac Mini either for many months. Perhaps Apple tweaked something behind the scenes lately?
 
The saga continues, alas:

After a few months of generally problem-free operation, the last revision or so of 10.6 re-introduced the pinstripes. Thankfully, they're easily dismissed via the usual method (unplugging and replugging the Mini Displayport cable).

However, it's worse in Lion. The pinstriping is present, but unplugging/replugging the display cable doesn't work anymore! Between this and all the other little things rubbing me the wrong way in 10.7, looks like it's back to Snow Leopard for the time being. A shame too, as I was really looking forward to autosave and versioning...
 
I don't usually bump threads, but I'm still curious as to whether other folks with u2211h/u2311h monitors are getting incurable pinstriping with Lion. It's one of the few things still keeping me from upgrading.

Hi, I have the 2011 Mac mini (2.5GHz i5 / AMD Radeon 6630M) and it works perfectly with my Dell U2311H.

Hope this helps. :)
 
I'm using the new purchased Mac mini Server 2011 and DELL U2311H now, having the same problem.

First I thought it was my old cheap MDP to DP cord's problem, so I bought a new set (MDP to DP adapter + DP cord) with a higher price, luckily it solved the problem at the first few days, and it started to act up again since this morning.
I tried the solution mentioned in the post before, but sometimes it helps, sometimes not.

I used to connect this monitor to my Macbook Pro (15" Late 2008, nVIDIA GeForce 9400m/9600m), and they work perfectly with no problems at all.
 
So, some sort of driver problem with the Intel HD3000 and 9400M/320M chips?
 
Another update:

So 10.7.1 is no better: Pinstripes remain regardless of troubleshooting method. Furthermore, if you fail to unplug/replug the display, it won't wake up from sleep, much like the original problem I described way back when.

Since I need to use Lion for Xcode 4, I brought the mini and the Dell to the Apple Store to see if they had anything to say. The genius agreed that it's likely a driver problem and forwarded the issue to the engineering team. Aside from that he just said 'well... you can hope for a software update, but there's nothing else to do, we can't test every kind of monitor.' Not the kind of help I was expecting for a product Apple advertises will work with most anything, much less one of the most popular IPS monitors. So... now I have an $800 Mac that I can't use for my work. Time to sell the mini, the monitor, or both I suppose...

I sympathise with your issue and no disrespect intended. However where does it say that Apple claims or advertises that their hardware will work most anything. There is no way any company can assure the customer that their hardware will work with all the other hardware out there. It's not technically or practically possible as there is no way they can test every combination of hardware. I don't think you can blame Apple for their computer not working with another manufacturer's display. It's hardly their fault.

The monitor works fine on my mini if use Windows 7. It is almost certainly an Apple driver issue.

As for third-party product compatibility, here is the advertising copy from Apple's 2010 Mac mini product page:

An incredibly compatible computer.
If you already have it, chances are you can use it with Mac mini. Plug in your own display, keyboard, and mouse. Turn it on. And just like that, everything works together. You can even swap peripherals with another desktop computer. That’s one of the great things about Mac mini. You can mix and match it with just about anything.

The whole point of the Mac mini is to use existing your existing display, keyboard, and mouse ("BYODKM" in Apple's parlance). I would be using an iMac if there were a matte display option. Even in 2011, there are still only a handful of 3rd party IPS monitors. Last year, the u2211h was one of only a few affordable IPS matte displays. I would be more understanding if the monitor were some fringe product from a no-name brand. As it stands, the u2211h has been a very popular matte alternative to the 21.5" iMac, and made by Dell, so I would hope that Apple is able to figure this out at some point.
 
Well you're taking that very literraly. Common sense tells us that it's not always that straight forward and not all hardware is going to work together and if it can then there may need some kind of fix needed. You're making the assumption just because Apple stated that you won't have any issues. Yes it could possibly be a video card issue maybe with the driver under OSX. The only thing you can do is send feedback to Apple and hopefully if there are a lot of people who do the same it will be fixed in an update. I don't mean to sound harsh but I think your expectations are unrealistic.
 
I understand where you're coming from... it's true Apple can't cover every hardware configuration. Yet, this is 2011, and we're talking about hooking up a monitor. Given the fact that Apple doesn't make matte IPS displays anymore, I think it is entirely realistic to expect them to support one of the most popular IPS monitors in the market.
 
I understand where you're coming from. However Apple is a business and like any business they want and expect you to buy their products. Granted they don't make a matte display but they obviously want you to buy their all ne it glossy display.

Like with any company they are not going to go out of their way or make a point to make a competitors product compatible just because they don't offer an equal product. Not to mention there are way to many models of display out their for them to make compatible and support each and everyone. I'm also not entirely sure whether there is hard evidence or statistics that that particular display is one of the most popular.

It may well be that a lot of people in these forums use it but that doesn't mean that worldwide it is one of the most popular. Lastly its probably a matter of updating the OS or the video driver which is not something that is straight forward and if done most likely will have to be included in a future update.
 
While it's Apple's call as to whether they support a particular 3rd party display, I disagree that Apple "expects" you to use their display with a Mac mini. Their product photos show it hooked up to an HDTV as well as an NEC monitor. Apple advertises that you can hook up your PC monitor, keyboard, and mouse. When Steve suggested you could hook up the mini to their new (and expensive) Cinema Display, the audience laughed.

Last year, the u2211h was one of the few matte IPS displays in the market for <$250 (I knew of only 1 or 2 others). Dell had problems keeping it in stock along with its predecessor, the 2209wa. Given Apple's focus on quality IPS-based displays for their desktop and iPad products, I assumed that Apple would have made sure OS X's drivers would work with the handful of affordable IPS displays available at the time. Who knows... maybe they did do testing and just didn't catch it with the 5 minutes they could spend on it before attending to more important tasks. Regardless, I do think it's an oversight that should be addressed. Now that the engineering team is apparently aware of it, we'll see what happens.
 
I think you misunderstood what I was trying to say. I was trying to say that Apple also makes displays so in that sense Dell and other brands like NEC, Visio, Samsung etc. are competitors. I agree Apple's main market for the Mini is switchers from Windows PC's and therefore it's safe to say that the Mini will be used with various brands of display, keyboard and mice.

At the end of the day it's not possible for any manufacturer to support all the various combinations their hardware is going to be used in. Apple has a feedback option where people can leave their feedback on issues and I'm sure if enough people comment on a specific issue they will act upon it. I think that's the best you can expect in a situation like this. Anyway I think we just need to agree to disagree and move on as where not getting anywhere.
 
Yeah, aside from people contributing compatibility/incompatibility reports it's out of our hands, so we'll see what happens.

In the event I sell the Dell and use another monitor, people can feel free to reply or PM me with future compatibility information and I'll update the original post accordingly.
 
I just wanted to contribute that I'm getting the subtle pin-striping on certain shades of solid colour with a Dell U2412M and a mid 2010 MacBook Pro i5. Running Windows 7 on the same Mac works perfectly with the display, no striping at all.

Have there been any developments here?

Thanks
