I have an OptiPlex 9010 with onboard Display Port & VGA
I am trying to hookup a new 58 inch Samsung TV which only has 2 hdmi ports and composite & component.
I need both hdmi for laptop hookups so I can't use them for the Dell 9010.
I want to run VGA to either the composite or the component.
Will the onboard VGA do this?
I have a cable like this:
Composite video only has 320 x 200 resolution. A VGA to HDMI adapter would be in order.
Color subcarrier frequency was constructed as composite frequency assembled from small integers, in this case 5×7×9/(8×11) MHz. The horizontal line rate was reduced (3.579545×2/455 MHz) and the frame rate was reduced to approximately 29.970 frames per second (the horizontal line rate divided by 525 lines/frame) from 30 frames per second. 320 x 200 color resolution is standard for composite video. Amber/Black and white single color monitors have slightly more but not much.
You don't get anywhere near 640 X 480 VGA resolution from composite video.
Laser Disk and Laser Disk players do not get better than the bandwidth limitation of the NTSC composite signal.
