WebSync signal polarity Multimeter: Disconnect the cable form the monitor. Put the multimeter to DC voltage scale. Measure the voltage on the sync signal wire coming from the VGA card. If the voltage is 4..5V then the sync is negative, if it is 0..1V then the sync is positive. Oscilloscope: COnnect the oscilloscope to the sync wire. WebI ran into the same problem of not being able to select full resolution, as my Dell U3011 has a sync polarity of +/- while the Dell 3008WFPs that I use for the sides have a polarity of +/+. However, by creating a custom resolution for these monitors with the Nvidia Control Panel I could not only see the sync polarity but also change it. After ...
