Just purchased a U2412M, and after functioning fine for about six hours, it suddenly became very dim. That is, I have the problem that Ekulie described in this thread a year and a half ago:[View:en.community.dell.com/.../19496830:550:0]
The diagnostic suggested in that thread had the same result for me: the solid colors were still dim. Judging from that thread, my monitor needs to be replaced. I ordered the monitor through Amazon. Should I go through Dell or Amazon for a replacement?
