TFT 120 x 160 (Chinese) Blue Background

[CHCHmark]

Hi guys,
I'm working with a 160 x 120 ST7735 TFT using the eSPI library setup 2. When it powers up I can see the expected code but there is a blue background over everything. I have tried resetting the colour order to no avail. Picture attached

Have no problems with this library and other displays so it could be a different driver chip on the display. Any thoughts gratefully received. Cheers Mark

Hi @CHCHmark,

I have not work with this TFT controller but seems there are several color set types. Can you try modifying this #define line in your setup 2 file:

#define ST7735_REDTAB

with these one by one:

ST7735_INITB
ST7735_GREENTAB
ST7735_GREENTAB2
ST7735_GREENTAB3
ST7735_GREENTAB128
ST7735_GREENTAB160x80
ST7735_ROBOTLCD
ST7735_REDTAB160x80
ST7735_REDTAB
ST7735_BLACKTAB

I suggest power cycling the display after each try

BR,
Tim

Hi Tim, Thank You, that was the answer. I only needed to try ST7735_GREENTAB to sort it. Appreciate your help. Cheers Mark
