These posts were split out from the Pro1x production and delivery thread, since this seemed a more specific and technical discussion. This one, I believe. I haven't gotten one, so I don't know, but I assume the instructions tell you which app to download. I also recall someone on discord saying the app asks for lots of permissions but works fine when all permissions denied. https://www.amazon.com/Android-Mirroring-Charging-Smartphones-Projector/dp/B08LN8Z6QX Quote Link to post Share on other sites

Hmm, strange. I wonder if the app can be reverse engineered to pull out what ever proprietary weirdness that allows this particular cable to work. if the device ever arrived, time to pull out APKTool....maybe can patch lineage to work without garbage app edit: Even if it did work, this not native HDMI out. it is a hacky work around. native HDMI support is still a lie Edited November 6, 2023 by phukfxtec note about it being a work around and not native support Quote Link to post Share on other sites

I don't trust it one bit. 1 Quote Link to post Share on other sites

This is an app that does all the work, and sends data out through the usb to a specialised unit in the cable creating a hdmi-signal. The principal difference is whether the chipset/phone itself does this, and any standard usb micro-docking or simple dongle can be used, or it is a generic software solution that works on 'any' phone with an usb-c port. I do not know any details on how a standard hdmi over usb-C works (did not read this: https://www.hdmi.org/spec/typec ). It might well use some of the many wires apart from plain data, and thus not be possible to support by an app alone, but requires the phone hardware to support it. BUT IF the sole purpose is to mirror what is on the phone screen, and the data signal is not needed for other stuff and the cpu power used doing so is not an issue THEN this would do the job. If you e.g just want to show some images on the phone to the family via a tv with hdmi, the app+cable WILL do the job. We have (at the least) one other thread on this subject...

I think it's time to close the door and move on. I'm still waiting for my astro slide. I was just lucky to have one of the first Pro¹-X shipped. Otherwise, I wouldn't have any android usable phone for me. I can't type anything (even swiping) on a flat surface without any texture on where the buttons are at any meaningful speed. I've tested with my Pro¹-X my typing speeds with the on screen keyboard is 30cpm vs 160cpm on keyboard vs 260cpm on my laptop. This is all a terrible timing problem of a triple blow. f(x)tec is just caught in the middle and Planet Computers too. 1 2 Quote Link to post Share on other sites

It has everything you need to capture. Then you just need to have a receiver and something to convert the signal to HDMI. I have no idea how. I do love scrcpy, though. I use it quite regularly.

It is simply that only one USB-c to HDMI cable works and requires an app and only mirrors. The Pro1X's USB port does not support GPU-out via alt-mode. Therefore things like UBTouch congvergence mode will never work, contrary to what was promised. As far as I understand, the solution that was demonstrated with that "USB to HDMI" cable relies on screengrabing and -casting over a network protocol and thus works independently of the GPU on any recent Android device. The screengrabbing part is probably the reason for the extensive permission requirements. It's also the reason why things like Netflix or Prime cannot be displayed using such tehniques (as they have DRM mechanisms in place to prevent screengrabbing), unlike with true HDMI-out.

I too planned to use this device for movie watching over HDMI.... Yet another data point that proves DRM is a cancer that ironically only hurts legitimate paying customers by denying experiences such as the valid one described here. This why i go back to the sea, Pay for the service but torrent the content guilt free. 🏴☠️ 1 Quote Link to post Share on other sites
