Title: WG D9200 "Focus" question
Post by: 1UP on March 05, 2002, 12:05:18 am

In the specs for the WG D9200, it says it has controls for "focus".  Does this mean that you can actually soften/sharpen the picture?  I'd like to soften the look of Mame and maybe hide the MPEG artifacts in Daphne a little.  TVs are TOO soft though, and windows is damn near unusable on one.  Plus, that irritating interlace flicker gives me an itchy rash!  :P

I think the focus knob is attched to the flyback transformer (forgive me if it's not called that on a raster monitor, but it does the same job).

I'll be sure to wear oven mitts, rubber boots, and use an insulated screwdriver.  A verrry looong screwdriver!  :-X

For everyone's information, ALL monitors and television sets have a focus control. The control is usually located on the flyback transformer. The focus voltage is actually 4,000 volts DC. The picture tube itself operates on approx. 20,000 volts DC.

Good information to know, Ken!
