Issues Related to Screen (Colour)
• Screen has poor colour resolution (16 colours).
- Use PC settings to set the colour to 24 bits (True Colour) or above.
• Screen colour is unstable or mono-coloured.
- Check the connection status of the signal cable. Or, re-insert the PC graphics card.
• I see dark or bright spots on the screen.
- Some pixels (red, green, blue, black) are visible on the screen due to the unique characteristics of the display panel.
This is not a malfunction of the product.
