I've been having issues hooking up my early 2014 13" MBA to an external CRT monitor (a Samsung SyncMaster 997DF) with a ThunderBolt to VGA adapter. The text appears blurry, and even more so the higher the resolution and refresh rate. When I went to "About this Mac" and clicked System Report, and proceeded to Graphics/Displays it seems to have detected as an LCD. Is there any way to fix this? Here's the information under Graphics/Displays (note, I changed the resolution to 768 as it isn't as blurry, native is 1600x1200 w/ 76hz refresh rate):
