1. I wasn't shipped a lemon, so I can't testify as to what happens if you get one. That having been said, the person I bought from had tons of 99.8% reputation and I swear, I have no idea how it go to my doorstep from China so quickly (custom stickers and all indicating it erally moved that fast). 2. I have no idea why HD4000 won't drive that 2560x1440 resolution over DVI/HDMI. I just know that HD4000 has that prowess to output it and I read somewhere that it only works over DisplayPort. So far, based on my HD4000 MBA and desktop, that seems to be true. I'll see if I can find you a source on that. edit: This is not the exact same ebay listing, but is from the same person and is the same product that I purchased: http://www.ebay.com/itm/New-Crossover-27Q-LED-P-27-DVI-D-Dual-Link-PC-Monitor-QHD-2560X1440-16-9-Pivot-/170909340487?pt=Computer_Monitors&hash=item27cafd9347 http://www.ebay.com/itm/New-Crossover-27Q-LED-P-27-DVI-D-Dua... edit2: Sources on the HDMI/DVI/DisplayPort discrepancy: http://communities.intel.com/message/160909#160909 http://communities.intel.com/message/160909#160909

Thanks for your reply. I just bought a new nVidia card (GTX 650 Ti) and it doesn't include a DisplayPort, so it looks like I'm out of luck on this :/ Thanks anyway!

  To clarify, I am driving my display over Dual link DVI from my Nvidia GTX-660. The resolution limitation is specific to both the HD4000 + HDMI/DVI. That ebay listing indicates that GTX 4xx's and 5xx's are supported. I would suspect yours will be fine.

    Oh, I thought you meant that it was a limitation of the screen. That's a relief, then. I have currently had a 22" LG for a few years, it might be time to get a new screen! Thank you for your help.

    No, the HDMI spec is restricted in the resolutions that it supports, it's nothing to do with the HD4000, which could be a separate issue

      HDMI 1.3 supports this resolution and there are numerous sources that indicate that the HD4000 will not drive a 2560x1440 resolution over a DVI port. Also, me and everyone else with a Dual link DVI port and HD4000 will tell you that it flatly doesn't work.
