Hello. I need an alternate way to change Pi screen resolution.
I'm using default Raspbian. 8gb mem card, formatted to FAT32, then NOOBS was put into it. Then installed like normal.
I haven't manually made any partitions.
So I have 2 screen.
1st one is the normal IPS monitor with variable full HD with other resolution. When my Pi is connected to this, the Pi will automatically use the full HD.
2nd screen is a 5 inch screen, with the resolution 800x400.
To make this screen work, I have to modify /boot/config.txt manually.
The Pi can't work with this screen out of the box.
If I modify the config.txt, I would not be able to use the 1st screen. The Pi can only detect the 2nd screen.
Now, the problem;
I want to use the 2nd screen, WHILE also be able to switch back to 1st screen anytime.
Lets say I have modified config.txt to use the 2nd screen. Then suddenly the 2nd screen broke, then I would be unable to modify the config.txt, because the 2nd screen broke, and I can't use the 1st screen too.
I don't want to use SSH.
How can I modify the config,txt, in this case?
Can I directly plug the micro-SD card into a PC< and adjust it manually? All I see on the SD card was a 'Recovery' partition; I can't see my Pi files.
Or is there another way tomake the Pi able to automatically switch to whatever screen I hook it up to?
This is the code I put into the config.txt:
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
Thanks in advance. Any help is appreciated.
May I first ask why you "don't want to use SSH"? Are you just unable to use it for some reason or is that just a preference? Because that's makes your options very limited, especially if you intend to edit your config.txt file without a screen.
The very first thing I did when I received a Pi was hook it up to my computer through an ethernet cable so that I could SSH to it. I didn't even have an extra screen to use.
2 reason:
1- I'm a lazy noob who don't know how to SSH. Will learn later if I really dont have any choice left, if my real-life work loosen its deathgrip
2- The ethernet is occupied (i connected the Pi to another Pi with ethernet cable)
