Title: 800x600 interlaced at 47Hz refresh - what sync will this be?
Post by: gearguy on April 04, 2005, 06:34:28 am

I am just wondering what sync rate a 800*600 res Interlaced signal at 47Hz would be?
Thanks in advance!

Assuming 1,5ms for sync and blanking I get a line frequency of 300/(1/47-0.0015) = 15.2KHz

Good, it would seem that my VGA monitor is capable of accepting a 15.2Khz signal then. :D
Thanks!
