HD610: Thank you very much for contacting the Intel® Graphics communities. We will do our best to try to assist you with this matter.
In this case, the thing is that due to the fact that you are using a HDMI to DVI adapter, the PC will limit the resolutions to that DVI port, meaning that it will support up to 1920 x 1200 @ 60Hz only. The best thing to do at this point, if you have the option of course, will be to get a HDMI to Display port adapter, that way you should be able to set the resolution needed.
Any further questions, please let me know.
I couldn't test the HDMI to DP adapter, as it's not so cheap...
So, I will finally keep the low definition for a while...
