If you have connected your TFT via an analog VGA cable, you might have some blurry vision or even flickering
|
|
|
|
|
in some cases. If the following picture shows some flickering or looks blurry, your display needs calibration.
|
|
|
|
|

|

|
|
To calibrate your display, go to [Randy Simons' page](http://randysimons.com/pagina_131_NL.xhtml) and do the following:
|
|
|
|
|
|
|
|
|
|
- open the [sync pattern page](http://randysimons.com/overige/tftAutoAlignPattern/)
|
|
|
|
|
- put your browser in full-screen mode (mostly by pressing <kbd>F11</kbd>)
|
|
|
|
|
- issue the auto-calibration on your TFT display (most displays have a specific *"Auto"* button)
|
|
|
|
|
- make sure the picture doesn't flicker anymore
|
|
|
|
|
- exit full-screen mode (<kbd>F11</kbd> again)
|
