#Every External Display laggy

So I have been having this issue for months and I can't seem to find a solution or a single other person who has experienced this. No matter what, every single time I connect my iPad to an external display, the display seems to be running at half the framerate of the iPad. The picture is very stutter and there is massive input delay. This happens with EVERY non apple app, every game, any app that's not a built in app. I just want to use my iPad like a console on the TV but it's unusable with how laggy this is. I've tried several USB C adaptors including the official apple one, I've even tried direct USB C Thunderbolt without an adaptor. I've tried over 5 different monitors and TV's. There is something wrong with how the iPad M1 sends it's output to the TV and I can't figure out how to fix this

I'm not sure what would cause that outside of what you've done. You've been pretty thorough in your troubleshooting.

If I were in your shoes, I'd try next steps:

  • Verify you're on the latest version of iPadOS (and are not in a dev or beta version)
  • Verify your iPad is not using Low Power Mode
  • Restoring the iPad from backup to see if it makes any difference
  • Contacting Apple to see if there's anything else to try

In addition to what Amy said, I'd thought I'd share a theory I have. It's possible that iPadOS is purposefully dropping frames to provide better performance for the game. Again though, that's just a theory.

#

@split pumice

#

If it only happens in games and not in any other applications. That theory would make sense. Also, not sure if this would help, but in iPadOS 18, there is a dedicated game mode to help improve the performance of games and latency with bluetooth devices. So you could try updating (if not already) and see if it makes a difference

I would try to test it out, but I don't personally own a iPad to try it.

are you mirroring, or do you have stage manager on, with the external display having its own content screens?

What difference does stage manager make? All that does is let you run apps in windowed mode

tame grove
#

It’s like the difference between mirrored and extended modes on a laptop or desktop with multiple monitors

split pumice
#

Yeah but I want mirrored. I don’t want extended

tame grove
#

Well, then that’s why you have lag

#

And that’s not going to change, sorry.

split pumice
#

Why. If the ipad is 60hz then the tv should be 60 hurts

tame grove
#

Has to do with the handling in the display chips.

split pumice
#

It won’t display with stage manager on. It just says “not charging” and doesn’t do anything

tame grove
#

And it’s an HDMI or USB-C native display?

split pumice
#

It’s my tv yes

#

So now I got it to connect with stage manager on. No difference in refresh rate. Still laggy. The only difference is the lag is now in windowed mode

#

And it’s still mirroring, not extending even with stage manager on

tame grove
#

There’s a choice that comes up when you plug it in… damn, I don’t remember the exact sequence, but you have to choose the stage manager icon somewhere in the sequence.

split pumice
#

No choice. I plug in, and it mirrors to tv. That’s it

tame grove
#

Look in control center

split pumice
#

Yeah it’s on

tame grove
#

and if you turn off and turn it back on?

split pumice
#

Nothing happens. It just turns it off and back on

tame grove
#

It’s not detecting something from the TV it needs. I had this problem with one of my monitors that used a DVI connector. The HDMI->DVI cable I was using didn’t carry some signal it needs

split pumice
#

I’m just using a standard hdmi 2.1 cable

#

This also occurs with thunderbolt

tame grove
#

The problem at hand is that you’re not getting the device to recognize the external as a display that it can set up the second stage for.

split pumice
#

Well I got it extended now

tame grove
#

now you should be able to put the app you want to run over on that display, tap/click the horizontal three dots and choose “Enter full screen”

split pumice
#

But how can you full screen an app

IMG_4109.jpg
#

My tv isn’t touch screen so it’s not like I can tap the 3 dots

tame grove
#

do you have a mouse / magic keyboard / game controller?

split pumice
#

Not on me

#

It’s an iPad. I wouldn’t use a mouse or keyboard

tame grove
#

‘cause that would be the next thing.

split pumice
#

How would you do it with controller?

tame grove
#

the iPad recognizes game controllers, and I think you can move the cursor over to it…

split pumice
#

Controllers don’t have a cursor though?

tame grove
#

I know you can use it obviously in the games, cause I’ve done that. But I’ve never tried doing multiple displays without my magic keyboard or mouse.

split pumice
#

I’ve never owned a keyboard or mouse. I never saw the point if it’s a touch screen

#

There’s no way to tell the controller which screen to control it seems

tame grove
#

You could turn on assistive touch in Accessibility settings, then turn on mouse keys and use your onscreen keyboard to move the mouse pointer to the second screen

split pumice
#

Wow that is incredibly unintuitive

tame grove

#

To me an iPad is just a jumbo iPod touch. Like it’s always been

tame grove
#

Well, if you want to not use 50% of its capabilities, you could look at it that way. I’d encourage you to broaden your mind - it’s a pretty powerful computer that happens to have a touchscreen.

#

and pen capabilities. I was doing all my work and stuff anytime I was out of the house on my iPad Air 5

split pumice
#

I just want JIT. I bought the iPad exclusively for 1 game initially and i just use it as a gaming device and my cell phone since all phones are too small

#

Oh god why is the mouse cursor a white ball? Where’s the arrow pointer?

tame grove
#

I’d suggest at least getting a cheap wireless mouse if you don’t want to use the Accessibiltiy route.

#

App cant be full screened

#

It doesn’t do anything

tame grove
#

I guess they don’t want to draw enough dots or something. That’s weird. That’s a question for that app dev. I guess. I

split pumice
#

Chrome and YouTube also cannot be fullscreened when clicking full screen

#

But at least so far I’m not seeing lag in the game

#

Can you position the mouse over one of the corners and try to drag the window to expand it?

#

If you set it to full screen on the iPad using the three dots and the tap them again and send to the external what happens

split pumice
tame grove
#

I suspect that the app can only work with certain resolutions and you’d have to manually set the external to that limited resolution

#

What app is this?

split pumice
#

Call of duty warzone

#

Retroarch also does it

#

And so does Safari, chrome and YouTube

tame grove
#

What resolution is the external display?

4k 3840x2160
