    So I went ahead and pulled the trigger on a Dell u2311h for my early 2008 MBP. It's quite of a shift in the size, which is great. However, I'm not really satisfied with the monitor (I will explain it later); first, let me just make sure that I plugged it in correctly:

    A1. I used the DVI cable that came with the monitor and plugged it into the DVI-D output on the monitor (there's another output called D-SUB or something on the monitor), and the other end of the cable I obviously plugged into my MBP. Was that ok as far as the monitor output is concerned?

    A2. What about the cable that came with my MBP? Am I supposed to use that one for best results, or does it not matter? What's the purpose of it anyway, since the cable is so short?


    Now to my complaints:

    B1. I can hear a barely audible, yet still annoying buzzing sound from the back of the monitor. Is there anything that could be done about it?? I tried rearranging the cables and also just plugging in the monitor into one socket on my wall and my laptop into another socket (with just these two devices plugged in), but it didn't help.

    However, if I increase the brightness on the monitor to 100, the buzzing sound will disappear. It is of no help to me though, since you can't live with a brightness level of 100!

    B2. I think the colors need calibration - esp. the colors red and blue I think are not so accurate. How to calibrate my monitor for optimal results (for free)?

    B3. If I look at the picture in the center of the monitor and then move my chair to the left and look at the RIGHT side of the monitor, the picture on that side will get slightly shadowy/glowy. I thought that having an IPS panel would benefit me in this aspect??? Same thing if I look at a pic while sitting and then standing up will as well cast some "shadow" on the screen. The worst thing happens at night in a completely dark room; this is what I get:


    Is there anything I can do??

    A 1: Isn't it an "input", as the signals go in there instead of going out? Where did you plug the other end of the cable into? The adapter/cable you speak of in A 2?

    A 2: That is not a cable, it is a small adapter, either Mini DisplayPort to DVI or Mini DisplayPort to VGA, and is used to connect a secondary display, as most external displays have their own cables, the adapter doesn't need to be 1.5m or 2m long.


    B 1: I had a similar problem, and the only solution was to bring the brightness up to 100% or down to the lowest setting.

    B 2: System Preferences >>> Displays >>> Color >>> Calibrate

    B 3: Can you compare your results with another IPS panel display?

    A 1: I'm not sure if it's called output or input, I guess the best way to put it would be "port." It's called "DVI-D and it's located on the back of the monitor. So I plugged into it one end of the DVI cable that came with my monitor, and the other end I plugged into my MBP.

    Here is a picture (I found it online, so in reality it's the white port that I'm using, not the blue one next to it) : http://img.photobucket.com/albums/v306/matic001/aa.jpg

    Should I do anything with the D-SUB port that's to the right of it?
    The "adapter" that originally came with my MBP though, is the "DVI-I(M)/VGA (F)" cable (here's the pic: https://www.applecomponents.com/media/parts/922-7179.gif). My dilemma here is what to do with this cable? Am I supposed to use it, or...?


    B 1: The thing is, it will only work for me if I set the brightness to 99 or 100. For the rest, the buzzing still seems to be present.

    B 2: Does the calibration work fine though? Is there a danger I could mess something up?

    B 3: Unfortunately not.

    A 1: Those are the video inputs, the left one is the HDMI input, the middle white one is the DVI input and the right blue one is the VGA input (called D-SUB). Then there is the USB input for the two USB ports on the right of the USB input.
    You MBP has a DVI out, full size.
    The adapter, that came with your MBP is a DVI to VGA adapter, but would be unnecessary, as you would convert the digital signal (DVI) to an analog one (VGA), and using DVI to DVI would be the best.

    B 1: Maybe you have to contact Dell and ask them about that buzzing noise.

    B 2: It works fine and in the end (use the Expert(Advanced mode) you will be asked for a name to save the profile as, thus you can switch between different profiles, if you think you messed something up. Maybe you can even find a colour profile online for that specific display and use that.

    Thanks, I'll give the calibration a try later. But in the meantime, I'd like to ask real quick a couple of other questions:

    1. How to enable the USB ports on my monitor? As it is right now, nothing happens when I plug anything into a USB port on there...

    2. When I use dual-mode with my monitor and MBP, is it possible to make it keep my dock and everything on the external monitor only, while on my MBP there would only be empty desktop and nothing else?

    3. What should my monitor settings look like? -- for example Preset Modes: should I have the Custom (RGB) setting enabled? What about Gamma in Color Settings? I have the "PC" option selected because if I select MAC it becomes quite brighter...

    1. Have you connected the MBP to the monitor via such USB cable?

    3. Do you talk about colour calibration?
    The gamma setting is up to you, what you like more.
    And you don't need to have the Custom (RGB) setting enabled, if you mean a colour profile preset with that. You create an entirely new colour profile, thus whatever profile you choose before, becomes irrelevant.

    1. Ohh, I see. That did the trick, thanks!

    2. Thanks!

    3. I meant just the default monitor settings that you can change with the buttons on the right of the monitor....

    3. Consult the manual of the display about that, as I can't find one online.

    I couldn't find it either... Apparently it's on the crappy CD that came with the monitor, but it will only work in Windows.... What a joke.

    Hmm, I didn't find any useful info in the manual.

    I think I might try and get a replacement for mine (A01) especially because of the buzzing sound.

    Two more things though: is there any word on when A02 is supposed to be hitting the stores?

    Also, should I really be getting another u2311h as a replacement? The thing that bothers me is that the IPS panels are supposed to display *true* colors - but how could I ever know if I will be seeing those true colors after calibrating my monitor? Just yesterday I tried to calibrate my monitor four times and it usually resulted in slightly dimmer display and perhaps more vivid/contrasted colors. But are those colors realistic? How will I ever know? What's the point of having an IPS panel then.....
