    I'm trying to display at 2560x1600 from my laptop via HDMI to the U3011 but it is only displaying at 1920x1200. The laptop is a MSI780DXR with a GTX570M with a v1.4 HDMI output.

    I believe the issue to be a limitation with the U3011 HMDI input as I thought that HDMI v1.4 was easily capable of displaying at 2560x1600. Reading through the manual of the monitor does state that its maximum resolution through HDMI is 1920x1200. I found it weird that such a high end monitor would not support its native resolution via HDMI. I've ensured that I'm using a v1.4 HDMI too.

    Does anyone know of HDMI to DisplayPort/Dual Link DVI that would support 2560x1600 (or other solutions)?
    :sigh:

    I imagine some of our resident monitor experts will be along shortly to tell you if this is likely to be successful, but with a bit of luck all you need is a £5.00 cable.

    *Edit* I was interested in this so I did a bit of googling and this is a common problem and not one with an easy solution. It appears that a simple HDMI to Dual Link DVI cable will NOT allow you to use a resolution of 2560x1600.

    I think you may be boned.

    Now the GTX570m has dual link DVI support:

    http://www.geforce.com/Hardware/NotebookGPUs/geforce-gtx-570m/features

    But I guess it depends upon which outputs the partner has decided to put on the board.

    You may be in a strange situation where the card and the monitor both support the resolution but that there is no way to successfully connect them due to the laptop manufacturer not providing the correct output port.

    I also Googled some laptops with the GTX570m and it is common for the only output to be HDMI 1.4.

    While HDMI 1.4 actually has the bandwidth to carry 2560 x 1600 it seems that it is very uncommon for display equipment to support this resolution over this connection.

    It appears that very few laptops are designed to run displays at this resolution, and those that are will commonly have a mini displayport output.

    as far as im aware, you need the included dvi cable with all pins (i.e. not standard ones) or use a displayport cable

    did you not get a dvi with it?

    The graphics card only has an HDMI output not dual link DVI or display port

    The monitor does not support 2560 x 1600 over HDMI.

    There are no passive adaptors available which support 2560 x 1600.

    There is specialist equipment which will convert the signal and support 2560 x 1600

    http://www.3dbroadcastsales.com/description.php?model=1822

    But as you can see from the price this is unlikely to be a practical solution for most.

    I would say that you will not be able to drive your monitor at its native resolution with your current laptop.

    I believe that the Dell monitor predates the HDMI 1.4 standard which is why there is no support for the higher resolution.

    Unfortunately, I think jimmyjj you're exactly right with : "You may be in a strange situation where the card and the monitor both support the resolution but that there is no way to successfully connect them due to the laptop manufacturer not providing the correct output port."

    I was close to buying a cable like the one you linked, I guess I should have done some research before purchasing the laptop. I assumed that the monitor input would have been fine. Strange that MSI decided to provide HDMI and VGA connections on such a high end laptop..

    The specialist equipment is indeed not ideal with that price unfortunately. I'll most probably just be switching monitors with my brother who has a 1920x1200 monitor. He'll be pleased at least..

    Thanks for confirmation!

    HDMI is limited port, the reason? Because Sony and other companies supporting developing HDMI, focuses on TV. The only reason why HDMI 1.4 can go that high resolution, ease because the bandwidth was increase to accommodate 3D TV's. That is why I don't like HDMI.. it's all about TV.. not computer. I try my best to only buy laptops with DisplayPort.

    HDMI 1.3 was released in 2006, which support 2560×1600. I can conclude that the U3011 (which was released several years after) must be using HDMI 1.3. I don't know for sure.. I am just assuming. I'll be really surprised if it does not. Then again maybe Dell didn't want to pay the high HDMI royalty fees.

    But, I think you need to use one of those "high Speed' HDMI cables. Why I think it's a worthy try? Because the max resolution of your monitor is the max of HDMI 1.3, and usually specs are always pushed to extremes to give impressive figures. So you want everything on your side to be able to support this.

    If that does not work. Try forcing the GPU to output that resolution via custom resolution. Try different drivers (Nvidia or laptop manufacture own drivers (even if the driver version matches)). Remember that it could also be the GPU drivers.

    To be clear: I can't promise anything. Usually I try to attempt to try it, but my monitor is 1920x1200 only (U2410). So you could be waiting your money. So I would get a 5-6$ cable, if you really want to try, but don't have your hopes up.

    Thanks GoodBytes. I thought I had a highspeed cable already. This is the model:

    http://www.amazon.co.uk/High-Speed-...YDHU/ref=sr_1_5?ie=UTF8&qid=1319193286&sr=8-5

    I also have this DVI to HMDI converter that came bundled with a GPU (looks a bit cheap) that I tried with no luck. So desktop GPU DVI to HDMI converter to monitor still didn't display at full resolution which leads me to believe the monitor input is the problem.

    I also thought that drivers could be an issue but there aren't even any drivers available for the GTX570M on nVidia's website! It's only availale through the laptop manufacturer's site.

    I might call dell just as a last resort to really confirm if they fitted old HDMI technology to their top monitor..

    oh well :(
    Hopefully it's just a broken port, and a replacement monitor will have that fixed. (Yes you get to keep your monitor, while Dell send you the replacement, and Dell e-mail you a pre-paid shipping label to you, or have one in the box of the replacement one, so that you don't pay anything)

    Just spoke to a clueless Dell support technician who confirmed that the monitor is only capable of 1920x1200 when using HDMI. I'm quite disappointed with Dell right now.

    Hmm me too.
    Display Port is backward compatible to HDMI.. maybe an adapter from HDMI to Display Port can be looked into.

    Did you forcing the resolution with your GPU?
    Open the Nvidia Control Panel, go under "Change resolution", click on "Customize" button, then click on "Create custom resolution".

    Enter the resolution values, click on Test. See if it works. If it does, click on the "Yes" button, saying that the resolution worked, and now select and apply the resolution (as we only tested the resolution).

    Plan B, is to use an HDMI to DVI plug or adapter, and use the monitor second DVI.

    I've tried to force the resolution just like you described earlier on with no success.

    I also have a HDMI female to DVI male adapter that I tried to plug into the second DVI port but that didn't work either. I thought maybe an HDMI to component cable could work but I have to get hold of one first!

    ok so it's the GPU to the problem. If HDMI to DVI does not work, then it's not the monitor (or it could be both), but it should normally work.

    I didn't explain well enough. It doesn't work, yes, but the connector I have is a DVI-I rather than DVI-D so the converter doesn't even physically fit. It has the extra 4 pins (2 either side) of the large flat pin on the DVI connector. The U3011 doesn't support those 4 extra pins.

    Usually a monitor DVI port only has the pins for DVD-D pins, so that you don't pass analogue signal through, which no analogue to digital converter has been implement for that plug, so it won't work.

    I went ahead and looked up the plugs for that monitor:
    [​IMG]
    Sauce: http://www.anandtech.com/show/4070/dell-u3011-review-dells-new-30-inch-flagship

    It looks to me like that cable will totally solve your troubles, no?
    It even states:
    For 2 pounds, i'd say it's worth the shot, but i must admit that Goodbytes lost me a bit when analog signal became part of the equition. HDMI and DVI are (to my knowledge) pin-identical and both digital (TDMS) signals, and neither that cable nor the monitor has any physical pins for passing through the analogue signal, so it seems to me it'd be a non-issue. Feel free to correct me on that tough :D

    Ok I am feeling free to correct you :p

    DVI, is not just DVI.
    You have all these bad boys:
    [​IMG]

    DVI-I is digital AND analogue only, but single link (original DVI, if you will). Meaning it can't exceed 1920x1200 on digital. Also it carries analogue.

    DVI-I will all it's pins, is the same as above but dual link.. where it can supper higher resolution or more colors.

    DVI-D single and double, are the same as above but analogue pins are not part of the cable/plug, so it's not carried.

    DVI-A is ONLY analogue signal.

    Usually the monitor doesn't care about analogue signal, the reason why this exists is for graphic card so that it can accept a DVI to VGA converter, or for DVI-A plugs. I don't know why DVI-A exists... I don't know if it's too fool people, or it supports features or something over the traditional VGA plug, but I haven't seen it. But know knows, it was the year 1999, they probably thought the end of teh world would come in 2000 or something :lol: (my guess is for CRT monitors, in the care DVI is adapted really fast, which was not the case until LCD's market really started to pick up)
