I have when I boot up my computer, this monitor displays "Attention Signal Frequency is out of Range H: 68.5 kHz, V: 85.3 Hz Please change signal timing". I have hooked a crt monitor to this computer and it displays fine. How do I adjust the "signal frequency"?

The device driving the monitor is exceeding the horizontal and vertical frequencies that the monitor can display .....thus the "out of range". The specs for this state that the Horizontal Freq. is 80Khz and the Vertical Rate is 75hz. If you are driving this monitor from a computer running Windows, reboot the PC and use the F8 key to put it in SAFE mode. This will cause the video driver to default to a rate that the monitor can handle. Then go into the screen resolution settings and reset them. The native resolution of the monitor is 1680x1050 at 60 Hz. Exceed that and you'll get the "out of range"
The first one is the "out of range" issue. This means you are trying to display a screen resolution that is too high or too low and your monitor cannot display any image. Reboot your computer with another monitor or into safe boot mode and change the resolution to an industry standard (800x600 / 1024x786) and then see if your monitor will display the image. Once you can see the image on your monitor, you can make adjustments and it will automatically revert back if you cannot see the new display settings.
Update your video graphics card drivers to get the best possible resolution.
As for the buttons on the front of the monitor not working, this may be caused by the "out of range" issue above. It could also indicate that your monitor may be going bad. Try the above steps - if you get no image from the monitor, try moving the monitor to another known good computer and see if the button functionality works after it displays an image.
get the monitor that you used previously, and on the Windows desktop, go to display properties, in settings> advanced, under the monitor tab, change the refresh rate to 60, which is common on these flat panels.
That message appears when the Windoze display settings exceed the
monitor capabilities. If you will boot into windoze safe mode (F8 at
boot) and correct the display settings, the message should clear at the
next boot. Afterwards you can right click on the desktop and access the display settings to make final adjustments.
In your case, the refresh rate (V Frequency) should not exceed 70 Hz
first, 68.5 khz -85hz means horizontal raster frequency of source signal is at 68.5 kilohertz and repeats vertically at 85 hertz. (hertz means "cycles per second).
the sony monitor cannot "read" the signal being sent from the pc. change the screen resolution to a lower number like 75 or 70 hertz vertical.
