Hello:
Thanks for your help with those commmands, but after over an hour of research, I'm still at a loss about how to interpret the informaion presented. When I do xdpyinfo, it gives me a lot of information, some of which I recognize, such as "supported pixel formats" and the following:
default screen number: 0
number of screens: 1
screen #0:
dimensions: 1024x768 pixels (321x241 millimeters)
resolution: 81x81 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
What follows are some hex values and other jargon which does not seem to be relative to refresh rate. When I do xvidtune, it pops open two windows, one of which is a warning (and disclaimer) not to fool around with these settings unless you understnad what you are doing (I do not yet), and the other is the current config info, as follows:
HDisplay: 1024
VDisplay: 768
HSyncStart: 1072
HSyncEnd: 1168
HTotal: 1376
VSyncStart: 769
VSyncEnd: 772
VTotal: 808
horizontal sync: 68.68 kHz
vertical sync: 85.00 Hz
pixel clock: 94.50
I am unsure how to calculate the refresh rate from all of this, or even how to begin adjusting it within this interface. I found a decent site (
http://en.tldp.org/HOWTO/XFree86-Vid...WTO/index.html) that almost gives me an answer, but not quite. It presents a formula for calculating refresh rate:
RR = DCF / (HFL * VFL) or,
Refresh Rate = Dot Clock [or pixel clock?] / (Horizonal Sync Frequency * Vertical Sync Frequency)
I plugged in my own numbers, obtained from running xvidtune, therefore:
RR [refresh rate] = 94.50 / (1376 * 808) = 61.77566138
Does this appear accurate? Am I using the correct numbers in this formula? I feel like the answer is very close. Any help is appreciated.
Thanks!
