Question about ViewSonic G790 19" CRT Monitor
My ViewSonic G790 VCDTS21385-1 E monitor's horrizontal width got shrinked at once. it seemd like causing dry joints and really there were lots. So I resolder entire horrizontal defflection section but the problem is not cured.
SOURCE: Horizontal widh shrinked
Huh, it sounds like the monitor's horizontal deflection amp (a big transistor) failed. It is not so if you can feed it a good signal and get a wider picture.
You would replace that thing with a transistor with a similar drive profile (i.e. not a FET), if you practice the right safety; better to use a service tech to do it unless you were trained in it. Alternately, you can try freezing your monitor (wrap it to keep out condensation! I only mention this because it's freezing out, where I am....) and see if this helps the transistor recover; it's not that sage or safe though, because of the condensation/electricity hazard and unlikely event that you will ground a work bench surface to do this test!
Be safe and consider using lower-power-consumption flat screens in warm weather.

Use the menu button on the monitor itself to adjust for the screen size in DVI mode.
On your SVGA adapter, go to your display properties (right click on desktop) click ADVANCED and change the refresh rate to fix the first problem mentioned.
