It should be xtal1 and xtal0, which are the two pins connected to the crystal oscillator and the microcontroller.

I've encountered a problem like yours before, and the way to deal with it can be as follows:
1.First, adjust the resolution to 1024*768
2.Turn the refresh rate of the computer's display as shown in Figure 1 below

1. The main reason is: the resolution of the computer is set too high, which exceeds the maximum resolution that the LCD TV can support, resulting in the TV being unable to recognize the signal, so the display is not supported.
2. Solution: Enter the resolution setting interface of the computer, set the resolution of the computer to the lowest, first let the TV display the picture of the computer, and then gradually increase the resolution of the computer according to the picture effect, so that the picture display effect is the best; If you still can't display the picture, you can restart the TV and switch the source to HDMI mode again, and it will be back to normal.
-
1026x768,60Hz is the main resolution,TV is definitely supported,Unless the TV has other problems。

VGA, SVGA, XGA, SXGA, and UXGA are the names of different resolutionsXGA (Extended Graphics Array) is a computer display mode, which refers to the performance of computer monitors, especially the maximum number of colors and the maximum image resolution, also known as real resolution and physical resolution. xga 1024×768 (4:3)
UXGA stands for Ultra Extended Graphics Array, Chinese called "Extreme Extended Graphics Array", this kind of screen is applied on the 15-inch screen of the book, supporting a maximum of 1600 1200 resolution.
Resolution, also known as resolution and resolution, can be classified from two directions: display resolution and image resolution.

1. The difference between XGA, VGA, and UXGA is the resolution they represent:
1. XGA resolution 1024*768
2. VGA resolution 640*480
3. UXGA resolution 1600x1200
2. Definition of resolution.
Resolution can be classified in two directions: display resolution and image resolution.
2. Image resolution is the number of pixels contained in a unit inch, and its definition is closer to the definition of resolution itself.
