|I thought you said you had it working perfect with that old monitor of yours. But well, if u believe that something has happened after that, test your monitor with another machine/videocard. Fastest diagnose you can get! :) |
I also asked you if your monitor driver is recognised by the videodriver, and if things are blurred in the center of the monitor too.
Now, before I whitdraw,
Here is a little something about CRT monitors, if you are still interested:
Focus is highly dependent on the quality of both the deflection yoke and the electron beam gun. Implementation of a high-quality deflection yoke ensures that the electron beam will strike the proper position on the CRT surface.
Implementation of a high-quality electron beam gun and focus lens are vital to ensure that the shape of the beam when it strikes the screen is as close as possible to being perfectly round, not oval or elliptically distorted.
Loose focus can be caused by the physical properties of the CRT display. The electron beams traveling to the corners of the display are longer than those traveling to the center. Therefore, the display circuitry must dynamically compensate for shorter and longer focal lengths of the electron beams as they scan the screen. Also, the beam shape can be distorted as it passes through the magnetic field generated by the Deflection Yoke. If this distortion is not compensated for by a Dynamic Focus Lens, the focus quality, especially at the edges and corners of the display, will greatly deteriorate.
Sharp focus also depends on the amount of current needed to write the image to the screen. When more current is needed to write the image to the screen, the electron beam becomes somewhat thicker. This causes the beam to illuminate areas around the spot for which it is intended. This illumination of stray phosphor dots causes the edges of the intended image to blur.
Byebye, and I hope you get everything right soon!
