Just bought an iPhone 17 – device won’t recognize portable monitor for screen mirroring

The Synco product description now has a "Firmware Update for iPhone 17 Lineup". There are two files to download: the firmware update itself (intended for the monitor to run, not for your computer or your iPhone to run), and an instruction sheet.

Looks like you'll need a computer, a USB flash drive, and a powered USB-C dock to help update the firmware on the monitor. (If you have a USB-C dock for your computer system, you could temporarily unplug it from your computer, and its accessories, for use in updating the phone.)

i just checked details of the monitor. Looks like it uses this P2P technology, allowing connection without wifi or bluetooth.

If this monitor is not connected using USB-C (DisplayPort Alt Mode), or using AirPlay, then very likely, whatever input it is expecting is something that the iPhone does not natively support.

At best, you might need to install a special app provided by the monitor manufacturer. At worst, you might have purchased a monitor that is not compatible with your iPhone.

I'm not sure the 17 supports an external display via USB-C.

I know it only supports USB-2 speeds on the USB-C port.

The Technical Specifications for the iPhone 17 say

----------

USB-C connector with support for:

• Charging
• DisplayPort
• USB 2 (up to 480Mb/s)

----------

With the Pro and Pro Max models, you get support for Charging, DisplayPort, and USB 3 (up to 10Gb/s).

I'm not sure the 17 supports an external display via USB-C.

I know it only supports USB-2 speeds on the USB-C port.

As the iPhone 16e does not support a display, I suspect the 17 doesn't support it either.

The pro and pro max should support it.

If you updated the firmware as per the "Firmware Update for iPhone 17 Lineup" section on the manufacturer's site, be sure to contact them and let them know that their fix did not work for you.

Unless someone tells them, they may think that that firmware has put the problem behind them.

Here's the manufacturer's description of the monitor:

Synco – SYNCO XView M4 Selfie Monitor Screen for Phone Vlogging, Mirroring Connection, MagSafe Install, 10m Wireless Control, 4 Color Options

I would suggest consulting the monitor's online user manual – then contacting the monitor manufacturer if you still need help.

What you're trying to connect to is not an Apple product. Contact the manufacturer of the monitor for technical assistance.

I have the same issue. It works fine with my 16 but not my 17! It even works with my iPads and Mac. I also tested it out on an iPhone X. The device doesn't show up which in my case is called iScreen_p2p. I hope an update will solve this issue.

Hi, thank you for your comment. This monitor doesn't not require connection to the port. It can be connected wirelessly by just selecting the monitor name on the screen monitoring on Iphone. But the monitor name doesn't appear on only Iphone 17.

Generally such periperals need to be signed into the same wi-fi router as the phone, eg my television acts as a monitor because it is on my wi-fi.

What does the support team for the device suggest? Not sure if it applies to your specific brand and model, but on another site more video oriented a manufacturer’s support team acknowledged the issue and said they were working on a fix for their monitors.

I have the same issue and can pair the device with bluetooh, but when I go to screen mirroring the device does not show up.

I’m experiencing the same issue. I was able to update the firmware but I still cannot mirror the screen with my iPhone 17 pro (I’m able to do it with my 16).

How did you update the firmware? I’ve been trying for 2 days and no luck. I’ve followed all the steps posted
