Modern LCD [[Monitors_on_SGI_Machines|monitors]] that don't work well with the CRT-targeted vfo-microcode supplied by SGI may see improvement if used with a format that includes reduced blanking. [http://www.playtool.com/pages/dvicompat/dvi.html#blanking Reduced blanking lowers display format overhead needed to allow CRT screen redraws, overhead that doesn't benefit and may adversely affect LCD monitors]. Reduced blanking is primarily intended for use with DVI-connected LCD [[Monitors_on_SGI_Machines|monitors]], but any LCD [[Monitors_on_SGI_Machines|monitor]] new enough to take advantage of reduced blanking *may* also benefit when connected via the [[13w3_to_VGA|VGA]] port. Reduced blanking also can allow much greater resolution and refresh rates on systems with low pixel clock restrictions, such as [[IMPACT]] boards. Using reduced blanking, [[IMPACT]] systems have been proven to support resolutions of 1920x1200 at ~60 FPS. | Modern LCD [[Monitors_on_SGI_Machines|monitors]] that don't work well with the CRT-targeted vfo-microcode supplied by SGI may see improvement if used with a format that includes reduced blanking.
