Phase (in PC mode)
Dot Clock (in PC mode)
Dear Customer;
This appliance is manufactured with TFT LCD Display technology.
An image is created with colour light points called pixels in TFT-LCD appliances.
Each pixel consists of 3 sub-pixels [fixed colour (red, green, blue) light points].
As a requirement of production technologies, the abovementioned sub-pixels may cause
"sub-pixel errors" by way of lighting continuously or remaining dim continuously.
Please consider the following explanation about a possible sub-pixel error.
This problem can be encountered during the production phase as well as during use.
Sub-pixel errors are mainly 2 types.
Type 1 : The sub-pixel lighting continuously (may be red, green or blue)
Type 2 : The sub-pixel which is continuously dim (seems black)
The sub-pixel errors determined according to the ISO 13406-2 standard are given in the following table.
Depending on the resolution and scan frequency that
you input to the TV set, you may see a hazy or noisy
picture on the screen. In such a case you can use this
item to get a clear picture by trial and error method.
Dot Clock adjustments correct the interference
that appear as vertical banding in dot intensive
presentations like spreadsheets or paragraphs or
text in smaller fonts.
