Q: thunderbolt to HDMI resolution problems
Hello everyone, i recently bought a Hanns-g 27" 2k monitor (it has HDMI,DVI,VGA port) to connect to my MBP 13" (early 2011) running on . Now i know my mac can support such external monitor showing up to 2k resolution but the problem is, that in the monitor option shows only max 1080p. 
I'vetried to connect my thunderbolt port to the HDMI port in the screen via adaptor and and HDMI cable and most recenlty a belkin thunderbolt port to HDMI port with max resolution of 4k but i still get the same readings as in the pix above, also when i check my thunderbolt spec it shows no device connected even if there is a screen up and running on the same port....
would the use of the DVI port on the screen make any difference ? or is it just a problem related to my MBP ? thanks for any help guys
MacBook Pro, OS X Mavericks (10.9.5), 13" early 2011

In the monitors Advanced settings, make sure DP EDID is set to 2560x1440.
Your Mac may be too old to support resolutions greater than 1080p via HDMI.

In that case you will need to use DUAL-LINK DVI

Be sure to use a DUAL-LINK DVI cable. You can't tell by the connectors. Single link DVI cables often use dual-link connectors.
