MONITOR VERTICAL

Best Vertical setup

A multisync monitor or multiscan monitor is a monitor that can properly synchronise with various horizontal and vertical scan frequencies.^[1] In contrast, fixed frequency monitors can only synchronise with a specific horizontal and vertical frequency, limiting their flexibility.

Multiscan monitors appeared during the late 1980s,^[2] offering flexibility as computers moved from earlier standards such as PAL, NTSC and CGA to higher scan-rate standards such as EGA, VGA and SVGA. Normally, a different fixed-frequency monitor was required for each of these standards.

PAL, NTSC, CGA: ~15.7 kHz horizontal scan, 50 or 60 Hz vertical scan
EGA: 15.7 kHz or 21.8 kHz horizontal scan, 60 Hz vertical scan
VGA: 31.5 kHz horizontal scan, 60 or 70 Hz vertical scan
XGA: 35.5 kHz horizontal scan, 87 Hz (43.5 Hz interlaced) vertical scan (plus VGA modes)
SVGA: 31.5 kHz ~ 100 kHz+ horizontal scan, 48 ~ 160 Hz+ vertical scan, most commonly 56 ~ 85 Hz at 35 kHz and up.

With the introduction of SVGA, multiscan monitors became standard for personal computers supporting a range of resolutions and refresh rates. A typical screen resolution of the late 1990s was 1024x768 at 85 Hz, requiring a horizontal scan rate over 68 kHz,^[3] yet during system boot the POST display and operating system splash screen would be displayed at the standard VGA 31 kHz. Many MS-DOS and Windows computer games of the time would also switch to a lower resolution for greater compatibility, more colours, improved performance or to reduce the video memory required by the frame buffer.
