1) Briefly explain what happens when the VSYNC goes from '1' to '0' for negative sync polarization?
2) Briefly explain what happens when the HSYNC goes from '1' to '0' for negative sync polarization?
3) If I only know the refresh rate of a monitor, can I roughly say what the period of VSYNC should be? If yes, what is it? If no, what more information do I need to know to "roughly" determine this and with this new information, what is it (give a formula)? (Ignore back porch,
front porch and sync pulse negative timings)
4) If I only know the refresh rate of a monitor, can I roughly say what the period of HSYNC should be? If yes, what is it? If no, what more information do I need to know to "roughly" determine this and with this new information, what is it (give a formula)? (Ignore back porch,
front porch and sync negative pulse timings)
5) Suppose that I want to paint the pixel that resides in the 50th column and 200th row of the monitor to color 'cyan' (taking the upper-left of the monitor as the starting point). Knowing that my pixel frequency is 25MHz and my screen has 800x600 pixels ( 800 columns, 600 rows):
(Ignore the front porch, back porch and negative sync pulse timings)
5-a) How much time from the first time of negative pulse of VSYNC do I have to wait for until I get to control this pixel?
5-b) How many negative pulse of HSYNC should I apply from the first time of negative pulse of VSYNC until I have the control of the pixel of interest?
5-c) To which pin(s) from RED,GREEN, BLUE of VGA port should I apply a non-zero signal at the time when I have the control of the pixel of interest?
