Hi Kevin, thanks for taking the time to help us on this.
I don't know about bunnyfluffy, but I have solved this issue and I am now viewing this website at 2560x1440 resolution over HDMI. You guys need to give your hardware more credit 
I was able to add the custom resolution by following this article:
http://www.intel.com/support/graphics/sb/CS-029478.htm#HDGFX
I used the C:\Windows\System32\CustomModeApp.exe utility using the following settings:
Width: 2560
Height: 1440
RefreshRate: 55
Timing Standard: CVT-RB.
and restarted my laptop. The custom resolution was then available by right clicking the desktop and selecting the standard windows resolution menu item.
thanks!
