Microsoft Windows Logo Program System and Device Requirements — 100
TV-style large-format monitors (larger than 23 inches) must be capable of scanning at 1024 x 768 progressive at 60 Hz (and 59.94 Hz) for the 4:3 case, and 1280 x 720 progressive at 60 Hz (and 59.94 Hz) for the 16:9 case.
Note: Sizes for LCDs are the actual viewable image size, rounded to nearest inch. Sizes for CRTs are based on actual CRT size (not visible area) rounded to nearest inch.
B184.108.40.206 CRT-based monitor supports ergonomic timing standards
As defined in either the VESA Generalized Timing Formula, V. 1.1 or Computer Display Monitor Timing Specification, V. 1.0, Rev. 0, and a 59.94Hz variant of the 60Hz modes.
The monitor must, at a minimum, support the timings documented in either the VESA Generalized Timing Formula (GTF), Version 1.1 or the Computer Display Monitor Timing Specifications, Version 1, Rev. 0.8. Other resolutions and refresh rates may be supported, but for any resolution less than the required resolution, there must be a timing for 75 Hz or better. The standards help ensure a clear, flicker-free display for traditional PC computing.
To support optimal playback of video content, monitors must be able to operate with the 59.94 variant of the 60 Hz VESA timing. All references to 60 Hz timing in this chapter also include the 59.94 variant.
B220.127.116.11 – See B18.104.22.168
B22.214.171.124 USB functionality from either a HID or USB hub, if implemented, is installed separately from the monitor INF
B126.96.36.199 CRT-based monitor synchronizes to a new format in less than three seconds
This capability is important because sometimes a change from a high refresh-rate graphics mode to a 60 Hz (or 59.94 Hz variant) mode is necessary to optimize video playback.
When the scanning rate is changed from one of its valid rates to another valid rate, the monitor must resynchronize to the new format and produce a stable picture within three seconds from the graphics adapter becoming stable.
B188.8.131.52 LCD monitor or built-in LCD display contains display characterization data
LCD monitors and built-in displays must be optimized for Microsoft ClearType™ and other advanced operating system graphics features being implemented through DirectDraw, Direct3D, DirectShow, and GDI+. This optimization will require additional data regarding the characteristics of the attached display. These characteristics include, but are not limited to:
Digital interface (external or internal).
Vertical pixel striping orientation in normal orientation (subpixels of the same color aligned in vertical columns).
Subpixel format is RGB (ordered left to right). Other formats might be acceptable but must be characterized in EDID.
High contrast ratio (minimum of 50:1).
No scaling or image filtering applied when display is at native resolution.
Detailed gamma data.
Additional color information.
Monitor rotation capability.
