Inferior Resolution in Clamshell Mode

[hasantahir]

First, thanks for the great tool. I have noticed that when I operate in the clamshell mode, I am unable to set the two external monitors to the ⚡ resolution. Moreover, although the resolution in and out of the clamshell mode remains the same (in my case 1980 x 1200), there is a noticeable difference in the picture quality due to the absence of ⚡ resolutions in clamshell mode.

Below is a comparison of the image quality and difference in the normal and clamshell modes.
