Fixing Textmate's font appearance on an external monitor
A problem that had been plaguing me for a while was my main programming text editor's font appearance was dimmed whenever I launch it up on my Dell 3008WFP. To make things tricky, the problem only showed up intermittently. Sometimes it would look perfectly fine. See the pictures below for a comparison.
It took me a while to figure out what caused it. It happens when I launch Textmate with my monitor connected. If I launch it on my laptop first, then connect it to the main monitor, then everything is fine. I had wrongly suspected that I had a monitor problem (sorry Dell).
A quick search on DuckDuckGo http://duckduckgo.com/?q=textmate+font+external+monitor+problem shows that OS X doesn't seem to detect the correct font smoothing style for flat panels.
Choosing "Medium" fixed it.
I just had to share..
