I had a certain monitor for 6 years, then it died. I replaced it with a seemingly identical monitor (could be a different revision of the same model). I'm using it at the same, native resolution of the monitor, which is 1280x1024. But now anti-aliasing seems broken, in the sense that there does seem to be some attempt to anti-alias the fonts, but the results look horrible. Here is a sample from my own web page, as rendered by chromium:
My computer has nvidia video.
How would I go about diagnosing and fixing the problem? For example, could it be that the OS interrogated the monitor, got confused by the info it got back, and therefore went to some kind of fall-back setup where fonts aren't anti-aliased in the normal way? I do notice that when I log in to a fluxbox session, there is a noticeable delay now during which the monitor shows its icon indicating that there is no signal. That didn't used to happen.
Or could it be that the monitor is somehow trying to be smart and optimize things by manipulating the data it gets from the computer? Should I see if there is more than one nvidia driver I could be using?
