This document won’t go into all the variants instead, we provide conservative timings that should work with all displays. Video timings are a complex area with several different specifications, for example, VESA Coordinated Video Timings (CVT) includes four variants for common HD resolutions. Horizontal sync demarcates a line and vertical sync a frame. ![]() The sync signals occur within blanking intervals separated from pixel drawing by the front porch and back porch. Video signals have two phases: drawing pixels and the blanking interval. ![]() There are an increasing number of televisions and monitors that do support high refresh rates, but these are beyond the scope of this guide. This recipe includes the timings for four standard display modes using analogue VGA, DVI, HDMI, or DisplayPort: 640x480 (VGA), 800圆00 (SVGA), 1280x720, and 1920x1080 all at 60 Hz.ĬRT monitors typically support higher refresh rates in addition to 60 Hz, such as 72 and 85 Hz, but most LCD monitors do not. To work with standard monitors and TVs, you need to use the correct video timings.
