@quicksilver dont quote me on this, but yes i UPS will help level the spikes. a surge might, but i think the choke if there is one on a surge protector will not be that big compared to a UPS

@lolonois great stuff, thanks for sharing, I may give that try!

@rva-818x-laystar The only game i found running better than its DC counterpart is Marvel VS Capcom 2
the rest either runs the same or worse in the case of Dead Or Alive 2

@mitu said in Screen tearing in pi 4:

Try using fbi, it's an image viewer that works on the console also.

Thanks that looks promising. I’ll have to see if there’s a way to control which display it outputs to.

@mikeb hi there. How about you give us a little more info about your setup per this thread:

https://retropie.org.uk/forum/topic/3/read-this-first

We all have been there before with the frustration and trying to get things to work. I’m sure a different attitude will bring a better response from the community here.

@mitu thanks for the codeblocks sugerence i never ear about it.
In raspberry 3 retroflag cases if you use default script if you push power button it shutdown the pi and reset button reboot it.
With this code the power button, shutdown the pi saving changes and the reset button restart only emulationstation if you are in main menu, or exit game if you are in a game.

I checked pins and are the same but i dont know why in pi4 you push the button and the pi do nothing 😟

@planetdune Does the TV have a front RCA video input ? Try that and see if the signal works. Also, check to the /boot/config.txt has enable_tvout=1 added (should have been added by raspi-config).

@mitu This was helpful. I think I have solved the issue! Thanks

it was too good to be true :( i was right it doesn't work https://github.com/libretro/RetroArch/pull/11590#issuecomment-743402918

Cpasjuste created this issue in libretro/RetroArch closed (KMS/DRM) add support for custom hdmi_timings / modes #11590

None. </thread>

I sware I had it changed to what you said earlier. Changed both files and it's now showing my N64 ones. Hopefully I can get the rest to work... thank you.

@red_trev I’m currently in the exact same situation. Is displaying emulation station, as well as all emulators run through it, on the second display even possible? Sorry for replying to this old post, but I have searched far and wide without coming across any solutions (that doesn’t require x session, xrandr etc...).

@mitu

Thank you Mitu

Just thought about it since you mentioned the USB3 methods of storing and backing up roms

Thank you for the tip

Thank you Mitu

i will try that now

I had issues with Pi4 wifi too. In my case I was noticing it when sending files over Samba from W10 or using FTP, and also scraping problems. I'd get constant disconnects and transfer speeds of around 200kb/s even when it would stay working.

I found mentions online of known issues where noise from the HDMI output can disrupt the wifi signal. Every instance I saw talked about said it was only over a certain resolution (1440 I think), but I decided to try disconnecting my 5" screen anyway, which runs 800x480, and as soon as I did that the speeds went up to around 3-5MB/s and the connection stays stable.
