Acer X223W (1680x1050) LCD + Samsung SyncMaster 750ST (1280x1024) CRT. Second being a 'testing gear' for specific compatibility issues with some art designs & color calibration reference. The LCD (even if that big of a main UI for regular use) is a tricky renderer for precision, catchy flaws (specially in Fonts) and anti-aliasing artifacts when re-scaling in most drawing programs. Plus the usual ghostly cornering variations of the TFT flat panel. Nothing i can't handle... so far.
Absolutely no upgrade necessary as i'm always using both from close_range_desktop_type situations.
I'd use TeeVee only for console thingies if i'd ever urge for some 'gameplay variety' rather than computing stuff, must be cuz i've had to hook oldy stuff like Turbo GraphX-16 & a full-blast enhanced Ti-99/4A!
