Rotate Screen on Pi4

j_infamous

In the documentation for Pi 4 display. It states that display_rotate does not work on the pi4. What can I do to get my display and emulationstation to rotate? Please help!

There's no easy solution here, but you can add some configuration to cover almost all situations.

For the text console to be rotated, you'll need to modify /boot/cmdline.txt and add a video parameter at the end of the line
```
video=HDMI-A-1:1920x1080M@60,rotate=90
```
Of course, change the resolution to your actual display resolution if it's different than 1080p and rotate according to your needs.
EmulationStation supports the --screenrotate parameter for rotation.
Edit the autostart.sh script, in /opt/retropie/configs/all, and add
```
emulationstation --screenrotate 1
```
instead of the existing line. Replace 1 (90 deg) with 2 (180 deg) or 3 (270 deg) depending on how much you want to rotate your display.
Configure RetroArch for rotation by editing /opt/retropie/configs/all/retroarch.cfg and adding
```
video_allow_rotate=yes
video_rotation = "1"
```
Again, change 1 to 2 or 3, depending on how much you want the screen rotated.

For non-RetroArch emulators, it's up to each individual emulator, I don't know which ones support screen rotation.

This worked but my retroarch main menu is still not rotated. I cannot find the setting to turn this 90 degrees.

mitu

@j_infamous Could be that RGUI (the menu driver) doesn't understand rotation. Try using xmb instead rgui (can be toggled from the Configuration Editor).

j_infamous

I tried those and they didnt work. I also did null and of course it meant what it said and now I dont have a retro arch menu.

j_infamous

I have the menu back but still 90 degree off.

mitu

It must be a limitation of RetroArch's menu drivers.

j_infamous

No one else has complained about it? Seems weird. Maybe they havent gone to the main menu from retroarch.

mitu

I guess is not a common configuration and using the RetroArch menu is not something you do each time you run a game, so maybe it's not a game breaker.

Apparently it's a known problem. No solution so far.

Does the screen rotate for text in cmdline work on the pi3? If u don’t want to use display rotate and do it like the pi 4
Would command be the same with hdmi-a-1?

I have a pie4 and I love the way they have the new format setup for it except for 1 thing, no rotate screen fix for emulationstation. It really kills it for me, since I only have a vertical screen. So I am forced to run my rpie4 as a rpie3 to rotate the screen, and rpie3 is not as friendly to me. I have tried everything to rotate the screen as well to no avail. (Unless it has been fixed since the last post on here that I don't know about). Is there anyway the dev's can address this or why did they give up on it?

mitu

@Gryphon No sure what you're talking about - you can rotate the EmulationStation, as stated in the 2nd post of this topic.

@mitu said in Rotate Screen on Pi4:

video_allow_rotate=yes

Uncommenting this in the config doesn't add the screen rotate option in Retroarch's User Interface or Settings>Video menus on the Pi 4 even when Advanced options are enabled.

mitu

@victimrlsh I don't think the configuration option in the GUI is dependent of the video_allow_rotate being present or not. If I enable the Advanced options for RGUI, the Video Rotation option is in Settings -> Video -> Output. I'm not sure what version of RetroArch you're using, the location might be different on your system, but check in the same menu location and see if you find it.

VictimRLSH

@mitu I'll try using RGUI, that might help too.

VictimRLSH

@mitu Found it, and it works. Now I just have to locate the option to save this config for each individual game instead of every game...
