  • By “USB 3.0” I should probably clarify that I meant more like 3.x, or whatever standard supports the DP standard I need to achieve at least 60Hz minimum refresh rate @ 4K (ideally 120hz but I’ll take what I can get). You see, I’m old so from my perspective this USB 3+ shit still feels new and confusing for me, even having done a little bit of research. But I digress; you’ve pretty much got the gist of what I’m trying to say now.

    Anyway I have a Z Fold 7 so I don’t think my phone the limitation, here. But yes from what I understand, an adapter that supports either DP Alt Mode or DSC (Display Stream Compression) is what I need. Or both. I’m still not sure, cause one such adapter I tried claimed to support alt mode but my phone still stubbornly refused to go beyond 30hz above 1440p. I’ll look into that reddit post; thank you.





  • Well like I stated in my initial comment, my PC won’t POST after I replaced my CMOS battery and I simply don’t have the free time to tinker with it right now (Gigabyte X670E Aorus Master and it just gets stuck @ status code 7b or 99).

    So I figured that I could just pick up a $50 adapter that I can use my phone as a PC in the meantime, until I get the time (and money if it’s a hardware failure) to address the issue. I just wanted a quick $50 fix that I can plug my existing mouse, keyboard, display, and home theater system into, and carry on business as usual to hold me off. Not invest in Bluetooth fucking everything just for a temporary solution.   Problem is that the temporary solution I thought would be simple is actually a lot more difficult in the era of USB-C, thus proving the original point of this post. You have hundreds of different incompatible standards, all plugging into the same thing.

    The fact that my comments are confusing even a tech-savvy social media network such as Lemmy says it all. Things were a lot easier in the old days. If it wasn’t compatible, the cable physically would not fit. That is no longer the case in the era of USB-C.



  • All I want is a simple USB-C adapter with these ports:

    1. A USB 2.0 port (or two) so that I can connect my wired mouse and keyboard
    2. A HDMI 2.1 port that supports 4K 120Hz
    3. A USB-C pass-through port charge the phone.

    Modern Android smartphones will go into a PC-like desktop mode when they detect that an external monitor is connected (complete with a taskbar, and apps running in a window, just like a PC). Therefore I want to do that with my phone so that I can have something that resembles a desktop PC until I find the time to fix my rig.

    The problem is that I can find no such adaptor. They all revert to 30Hz at resolutions above 2560x1440. I’ve been told that a workaround is to get a simple USB-C to DP adapter, then a HDMI to DP adapter, then just use a BT mouse and KB. I don’t want to invest in a new mouse and keyboard just for that, plus converting the signal to DP means I’ll lose ARC and then my home theater speakers won’t work, forcing me to use Bluetooth for audio as well. I don’t want to go investing in bunch of Bluetooth crap just for a temporary fix. All I need is a simple adapter that just works with my existing equipment.


  • Tell me about it. I’ve been trying, unsuccessfully for over a month to find a proper USB-C adapter that will give me both USB-A 2.0 and a 4K 120Hz output from my phone via HDMI. (It has to be USB 2 because 3.0 and up ports steal bandwidth from the HDMI port on the adapter). You’d think it would be a simple task, but even the adapters that claim to support 4K @ 144Hz still drop the connection down to 30Hz every time I increase the resolution beyond 1440p. Hell, at this, point, I’d just be happy with 60hz.

    All I need is a simple adapter that will allow me to use my phone as a PC at a decent refresh rate, until I finally find the time and patience to sit down and figure out why the hell my PC won’t POST after I replaced the CMOS battery. Yet this has proven to be an impossible task.

    Literally every single day for me. I am lucky enough to have been blessed a job that is both easy and boring (literally just scan documents all day), which gives me plenty of downtime to find some people on the internet to stress me out since my job doesn’t. (Only took 20 years to find such a job.) Hell, I’m doing it right now!
