2021-01-23 RPi : 라즈베리파이용 LCD 해상도 변경

다양한 제품의 LCD를 라드베리파이에 적용중에 있을 것입니다

해상도 맞추는 방법에 대해 정리하여 올립니다

 

putty로 라즈베리파이에 접속하여 config.txt 파일을 열고

sudo nano /boot/config.txt

 

파일 제일 하단에 

hdmi_group=2                     # 1: CEA 모드 : TV 프로젝터 등에서 사용,  2 : DMT 모드 : PC, 라즈베리파이에서 사용
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=2
display_rotate=2                   # 0 : 정상 화면,     2 : 180도 회전 화면,      1/3 : 90도/270도 회전 화면

추가하세요

 

참고로 저가 사용하는 config.txt 파일 유첨합니다

(3.5인치, 5인치, 7인치 GPIO 및 HDMI 방식 DVPI / USRP Client 공용 입니다)
