Projector problem

So I've been playing my PS4 on my projector and it's been fine, but one night I hooked up my switch to the projector and it displayed in 480p for some reason so I obviously couldn't play with a resolution like that so I switched back to the PS4 and now it won't show anything, sometimes it boots into a black screen but nothing else, when I plug it into the projector it says its connecting to HDMI but then just says theirs no signal. I then plug it into everything else I have but it doesn't work, it only works for the switch now but it runs at 480p

I've tried plugging unplugging waiting and re plugging but nothing helped.

I plugged the PS4 into a different tv and everything was fine, even used the same cables but when I let it boot up and safely turn it off it still showed a black screen.

Tried changing the video settings on the PS4.

Went into safe mode, but even when I did safe mode didn't show anything but I could still move, I did the button presses to change the resolution but all it did was reboot it back to another black screen.

Ive plugged back in the switch and it worked but it still was at 480p and I've factory reset the projector but nothing changed. Recently it started to have audio play through the projector but still no video and I'm stumped

If it helps I'm using a Dell 1510x DLP projector
