 640×480 @ 60 Hz is the default Windows graphics mode (usually with 16 colors), up to Windows 2000.It remains an option in XP and later versions via the boot menu "low resolution video" option and per-application compatibility mode settings, despite Windows now defaulting to 1024x768 (and then only when running the default universal video driver and/or unable to detect the connected display's native resolution) and generally not allowing any resolution below 800x600 to be set.The need for such a low-quality, universally compatible fallback has diminished since the turn of the millennium, as VGA-signalling-standard screens or adaptors unable to show anything beyond the original resolutions have become increasingly rare, and are now most likely to be employed for specialist uses by enthusiasts - for example, arcade cabinet gaming PC conversions, or driving pico-projectors from wearable computers - instead of blithely connected up as a main desktop display by an unsuspecting casual user; however, as it retains such niche utility, the ability to "deliberately" set it (and indexed 16 or 256 colour modes besides, instead of now-normal 16/24/32-bit direct colour), nowadays as a special rather than default mode, has been preserved.
