TFT Basic Checks and Troubleshooting

While most TFT monitors are very reliable once correctly installed and configured, the initial set-up can be problematic - especially if you are not familiar with the particular quirks of a flat panel monitor.

The most important issue when first powering up the system after connecting a new screen is to configure the PC to the correct screen resolution - i.e. to the monitors "Native Resolution".

The Native Resolution of a monitor is the actual number of dots the panel can display horizontally and vertically.  For almost all 15" screens, this is 1024(H) x 768(V) - while 19" screens (not wide screen models) are almost always 1280(H) x 1024 (V).

Analogue monitors may or may not reconfigure the display to the correct resolution - and in any case it should be checked by going to the display properties as follows:

Setting display resolutionWindows XP, 2000, 98 etc: Right click on the Desktop (not on an icon) and select "Properties" and then click on the "Settings" tab.  The screen resolution slider shows the current setting.

Usually, the required setting is the highest that can be selected - although the PC might need to be rebooted once with the new hardware attached before this is the case.

Once the monitor is in the correct resolution, on an analogue monitor, the picture needs to be adjusted.  The monitor will usually have an "Auto Adjustment" which should get the setting close enough for initial use.  Once basically configured with the automatic settings, it is advisable to use a monitor diagnostic designed to show any if further slight adjustments are required.  Look at monitor tests for further information.
