Use the monitor's controls to size and position the screen *first*. Don't
use the software controls in the driver/software to size and position the
screen. Set them to their neutral or middle position, then use the hardware
controls on the monitor to size and position the screen. If and only if the
hardware controls don't give you enough size or position then use the
software controls. The reason that I say to use the hardware controls first
is that it could be that you currently have them set at a crossover point or
at a boundary for a range supported by the monitor, and it's just too damn
close to ensure a reliable sync when that resolution is first selected.
Often when adjusting the hardware controls for size and position, you'll see
a jump in the size or position. If you continue adjusting the controls
further and then back off again, you'll see another jump (before the one
before). Count the number of times you hit the adjust button to see where
is the range of this switchover, then make sure you do NOT leave the
hardware setting within that range. That switchover range is just too iffy
and you may not get the size, position, or sync when the video resolution is
selected that uses the hardware settings in that switchover range.
Also, you might want to check what refresh rate you are using at each video
resolution (640x480, 800x600, 1024x768, etc.). Pick something like 60 to 75
Hz at first and check that each resolution that you intend to use is
supported okay by the monitor. Many video drivers use the same refresh rate
for each resolution so, for example, 120 Hz might work okay up to 1024x768
but will cause the monitor to go unsynched at higher resolutions. Some
monitors also do not like certain refresh rates although they look like they
are supported. I don't remember the brand but using 85 Hz could burn out
the monitor although there was nothing that prevented the user from
selecting that refresh rate. Unless you really have an application that
requires a very high refresh rate and it actually gives you some visible
benefit, I'd probably leave the refresh at 72 to 85 Hz (which gets used for
all video resolutions).
