I built a new intel-based pc. I bought a ASUS Extreme N6600 Silencer, based on the NVIDIA GeForce 6600 chipset. I ran into the same problem with my last pc. It appears that any nvidia chipset that tries to talk to my Sharp LL-T2020B monitor won't work at any reasonable resolution. If I turn it up at all (using either the nvidia manager or the control panel) I get horrible ghosting/trails/jittery images. These are the examples I've photographed. If I turn it up to some higher settings (like the recommendd 1600x1200 the Sharp manual calls for) the monitor blacks out and says, "out of timing; 47 hz V, 48 kHz H" and I have to restart and change the resolution.
The sharp manual includes a list of Hsync, Vsync, and Dot frequencies for each of the display settings in Digital Mode. (I only use Digital Mode -- analog mode looks even worse, almost unreadable). However, my nVidia manager offers no way to control these settings, at best controlling a refresh rate (60, 70, 75). the higher the refresh rate, the viewer resolution options are presented.
On the last computer I "solved" the problem by installing a Sapphire/ATI card instead of nVidia. On this PC I was hoping tha tI could instead just adjust settings until it works, but I have run out of settings and ideas to look at. ugh.
I also notice similar ghosting trails even inside the POST test, before windows even has a chance to turn on.
I'm dying for suggested fixes.
ugh.... just found another nvidia menu. there is a "Advanced Timing" menu... it has a lot of scary parameters that remind me of XWindows. I even have to agree to a disclaimer threatening potential physical destruction of my monitor... Unfortunately the options are not matched to what my simple sharp manual had....
# mode and timing
# timing standard
# flat panel scaling
HORIZONTAL PIXELS
# front porch
# back porch
# sync polarity
# sync width
# scan rate
# active pixels
VERTICAL LINES
# front porch
# back porch
# sync polarity
# sync width
# scan rate
# active pixels
...finally
interlaced mode
pixel clock (not adjustable)
