This compact, high performance video scaler takes the analogue VGA signal from your PC (or other device) and converts it to a DVI-I (digital & analogue RGB) output. It\'s also supplied with an adapter cable which allows you to convert and upscale to component video signals (YPbPR or YCbCr). Both digital and analogue video signals are available on the output connector for direct connection to your monitor or projector. The input resolution is automatically detected, whilst the output resolution and refresh rate can be adjusted using the built in on screen menu (OSD). Push buttons on the unit provide full control of brightness, contrast , RGB level, and H-V position. The DVI output provides digital rendering of video without the losses associated with an analogue interface, making it ideal for use wiith LCDs, Plasma displays and DLP projectors DVI-A output modes PC (RGBHV) HDTV (YPbPr, RGBHV) VGA 640 x 480 60/72/75/85Hz 1080i - RGB 1920 x 1080 60Hz VESA85 640 x 400 85Hz 720p - RGB 1280 x 720 60Hz VGA70 720 x 400 70Hz 576p - RGB 720 x 576 50Hz SVGA 800 x 600 60/72/75/85Hz 480p - RGB 720 x 480 60Hz XGA 1024 x 768 60/72/75/85Hz 1080 - YPbPr 1920 x 1080 50/60Hz Mac 1152 x 864 70/75Hz 720p - YPbPr 1280 x 720 50/60Hz WXGA 1280 x 768 60Hz 576p - YPbPr 720 x 576 50Hz 1280A 1280 x 960 60Hz 480p - YPbPr 720 x 480 60Hz SXGA 1280 x 1024 60/75Hz DVI-D output modes PC (RGBHV) HDTV (RGBHV) VGA 640 x 480 60/72/75/85Hz 1080i - RGB 1920 x 1080 60Hz VESA85 640 x 400 85Hz 720p - RGB 1280 x 720 60Hz VGA70 720 x 400 70Hz 576p - RGB 720 x 576 50Hz SVGA 800 x 600 60/72/75/85Hz 480p - RGB 720 x 480 60Hz XGA 1024 x 768 60/72/75/85Hz Mac 1152 x 864 70/75Hz WXGA 1280 x 768 60Hz 1280A 1280 x 960 60Hz SXGA 1280 x 1024 60/75Hz
