Using OP7 Pro as desktop mode and also charging. Cable solution? - OnePlus 7 Pro Questions & Answers

Hi all,
I've purchased OP7 Pro on launch and I'm happy that it supports DisplayPort. I'm going to be using desktop mode in my office. I would obviously need it to be charging while working.
Is there a 2 in 1 dongle solution where you can use display port and charge the phone at the same time?
Does USB C would even allow that kind of dongle and is it possible?
Any other solutions on my case?
Thanks in advance
Edit:
would something like this work?

I am trying this one with my OP7 and it is working pretty good.

Are you able to use a USB keyboard and mouse HDMI out and power

[Q] A dock or some way to use external monitor, keyboard, and mouse?

HI all,
I've been realizing lately that my Nexus 5 does just about everything I need anymore. I hardly ever need a PC for anything except for the full size monitor, keyboard, and mouse.
Now, I think I can use USB OTG and connect a Mouse and keyboard. But, is there a way to connect an external monitor as well?
I see that there is a Docking station for Samsung Galaxy phones that seem to do what I'm asking, here:
http://www.samsung.com/us/mobile/cell-phones-accessories/EDD-S20JWEGSTA
I've googled but cannot figure out if there is anything out there that would work for my Nexus 5. Does anyone have any suggestions?
externally powered USB hub. I used my friends once, had a hdmi output also and it worked flawlessly. (and by externally powered, i mean one that draws power from an outlet, not the phone itself)

Best bet is Bluetooth keyboard/mouse and use a HDMI out dongle and plug the phone into a wall outlet.

Now that sounds like a good idea.
Are you sure I can connect a keyboard and mouse over Bluetooth at the same time?

One way to find out... could also just get a keyboard with built in mouse like this or find one of these.
For android 4.4.2 and up use Chromecast for video& audio with HDMI monitor with speakers and Bluetooth for keyboard and mouse. Need sw app Andromium OS and/or Kodi too.

Dextop setup...

Starting a thread to see what kind of kooky and cool ideas peeps have come up with for their setup.
I just bought another Logitech MX570 trackball mouse. My 3rd. I like to go back and forth between traditional mice (MX Performance) and trackball so I don't get carpal tunnel and tendonitis. I'm up in the air about the dedicated keyboard. I will probably get the Logitech K800 as that has been my favorite so far. I would like to try the Craft but too expensive.
I know many of you are just going straight usb-c to HDMI adapter and using Bluetooth accessories. Those are welcome too. It would be really nice if Logitech came out with a sweet sweet keyboard with touchpad built in. There are a couple but the cheap one is just that, cheap and low quality. I bought my mom the K400 and it works fine for her but not for me. Logitech needs to step up their game on a keyboard with touchpad built in.
I am also using Logitech because of the unifying receiver so only USB port is taken for 2 accessories. Have not decided on a USB thumb drive yet.
What setups are you running for productivity with DEX? Please share so there is a thread peeps (that actually use the search function) can come and see what options there are to fit their workflow. Or haven't thought of.
I will update later today see if my USB controllers work for emulators and what the latency is, which I am hoping is just as good as mouse input. I was expecting critical latency that would make the experience bad.
Anybody try with a USB powered monitor yet?
I'm sorry, but..... pics or it didn't happen, right?
I invested in this dex stuff just as a hobby. I already have 4 pc’s plus a laptop and an iPad Pro 12.9 i carry with me daily.
I passed on it with the note 8 but thought to give it a go the note 9.
I also use the mxperformance mouse for my pcs but i picked up a jelly comb foldable portable wireless keyboard. It has a click-style mouse pad and the keypad is pleasant to use. I also picked up the dex pad , hdmi 2.0b latest spec hdmi cable.
I guess a good way to use this setup will be when I download films to the device. Rather than copy the file over to the pc, i can just connect the dex to the display and have better flexibility.
I found the jelly comb folding keyboard to be crap. Double characters everywhere. Moved to a generic wireless mouse on one of the USB ports and an MS folding BT keyboard. It's replaced my work laptop for 80% of tasks. Oh and powering the HDMI adapter by a Nintendo switch USB C power supply as it kicks out 2.6A which is enough to charge the phone at the same time.
I probably won't post a pic (if I even remember) until Friday or Saturday. I think I will try using it one day and a USB 3 thumb drive. I think DEX only supports USB 2 though. Another missed opportunity by Samsung to make this an even better pseudo desktop experience. Did Sammy use 3 or 3.1 for their USB C? Having two or even one USB 3 A port would've been sweet for local storage. Between a Logitech unifying receiver and a SanDisk UltraFit USB 3 drive and you're talking one smaller desktop.
Samsung could make some corny commercials pitting it against Intel NUC boxes like their Apple commercials. ???
Hi guys I have my dex set up, however I'm looking for a Bluetooth keyboard my monitor only has an hdmi, vga connection so I need advice on what will be my best option maybe I should get a cable with a USB receiver for an wireless keyboard any inputs are welcomed thanks.
I'm using my Note9 with Dex running on HP X3 lap dock. Great setup for travel but also when I need to edit things locally on the phone----tasker for example. Everything works on the lap dock including sound. Track pad works but could be better.

Woah, you have a working sound for hp elite? Is there any special way to get it?
I had picked up a DeX dock from Amazon for 60 bucks. I used a logitech anywhere BT mouse and the blue BT keyboard. Mouse and keyboard work great. Resolution looks crappy, seem kinda blurry for a 1080p screen. Still needs work, I was hoping to get the DeX working good enough to use as a htpc streamer for my living room TV. Still fun to play around with tho.
Sent from my Samsung SM-N960U1 using XDA Labs
does DeX work with any cheap HDMI to usb C adapter that supports 4k and 60 Hz? There are some on eBay for 7 bucks
dex output is crystal clear for me. I have used this on an lg 4K 27 inch monitor and my old school plasma Panasonic 3D display from 2011
I have a late spec hdmi 2.0b cable and again the resolution is not blurry at all. Plenty of videos on the web to also show the clarity .
Yes dex works with a regular hdmi spec cable usb c to hdmi. I have also used dex with just a cable (waiting on the pad tho show up)
What happens when incoming call?
Hi. Not sure where to post this. Thinking of jumping from iPhone to Note9
Can somebody tell me if I will be able to use the Note9 as a normal handset with an incoming call? (While in Dex). Everything I see indicates the acutal Note9 runs independent when docked but I can't find any example of making/receiving a call on one.
I want to use a USB extension cable and just be able to use the phone like normal when connected to Dex. Not sure what happens to the audio if I'm also using external speakers via Dex.
Thanks!

I've received several phone calls when on DeX.. Since I'm working in a personal room, I'm just answering the phone calls using speakerphone.. If you're using external speaker, the audio will be routed there (I once used my UE Boom 2 speaker for answering call)
thanks.
I know I'm still connected to Dex via a USB-C extension cable but I'd like to be able to just pick up the phone and use it "privately" like normal. Is that possible?
I believe something changed with the Note9 making it work differently with Dex.

If you're using USB-C to monitor, in my experience, you can just answer phone normally on phone

Apple's Magic Keyboard and Magic Mouse 2 work both flawlessly. I only wish my Dex cable was longer, to truly be able to have the TV far from me...

OTG hub doesn't work

Hello guys,
I have a problem with my OP7 pro, I have this OTG hub NOVOO USB C Hub (8-in-1) HDMI 4K,...
Originally bought for the Mate 20 pro, and was working fine except on this OP7 pro (and even without the IpadOS 13). When I connect it to the OP with and SD card it seems not connected at all, even if the OTG mode it's on.
Do you have any solution? What can I do? Other USB c key seems to works fine, anyway.
Thanks

There used to be an option in developer options.
Enable usb host or something on the OnePlus 5 may still be the same.

I found a solution to make the hdmi hub working, these are the steps, you need to follow them in order otherwise it'll not work:
Connect the hdmi cable to the hub and the tv.
Then connect the usb c of the hub to the power source and wait 10 seconds.
Then connect to the phone and wait.
The power source needs to be always connected otherwise the hub doesn't work.

Can I boot when charging? Non root? T387 At&t 8.0

Hello all,
I'm trying to install this in my car and need to power on when it's charging.
I have macrodroid and it's asking for root access.
I've looked everywhere and it doesn't seem like there is much support. Anyone have a US rooted Tab A 8.0 T387?
Is it possible to power on while charging without root access?
Thanks in advance!
Sup @hd2 head, wondering if you ever got this working? I'm looking for a tablet car solution and the T387 looks perfect. Did you get it to play nice with everything? thx.
No I just ended up cutting a notch out where the buttons are :-/

I see... Is everything else working fine with Macrodroid? I need a tablet for my e90 bmw with the MOST optical system, but don't want to run a old Nexus 7 like people did 5 years ago. Are you able to charge and play music from USB simultaneously? Do you know if any tablets would support that, either MicroUSB or USB C?
How do you use yours? Just connected to your stereo BT and play music that way? With my 2006 car, that is not an option stock, we must buy a MOST adapter, then we can use BT streaming. I would however like to play music from via USB into the MOST adapter, but would need to use some sort of hub that supplies power to tablet while tablet streams to MOST adapter. From my reading, seems like USB 2.0 is not allowed to do that? Not sure about USB C though.... anyone?
thanks!
My aftermarket head unit has an aux cable input. I'm using that for audio.
I have a macro set to give me the power off option when I take the key out (stop charging)
I routed the car charger to always be charging the tablet when the key is in

Question Ethernet Hub for Pixel 7 Pro

I have tried 2 different Ethernet adapter/hubs with my Pixel 7 Pro. They are: https://www.amazon.com/gp/product/B09LCHDRP9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and: https://www.amazon.com/dp/B07W52R8KY?psc=1&ref=ppx_yo2ov_dt_b_product_details These will not allow the Ethernet tethering setting to activate on the Pixel 7 Pro, although both work instantly with my Samsung. I need one that will put a mouse pointer on the phone's screen and allow the use of a keyboard, and may need power input, unless I can power it with the phone upside down in the pixel stand. If nothing else, a working plain Ethernet adapter, and I will use Bluetooth mouse and keyboard. Google sells one for their 4k chromecast, but they fail to specify if it will work for Ethernet tethering on the Pixel 7 Pro.

I haven't been able to get anything to work with stability on either of my two docks so I don't have a large enough selection to make a definitive statement on the support, but the farthest I've gotten is using my dock that has an RTL8153A-4. It will work for a bit, but when pushing enough data it'll end up resetting. Hits up to 400Mbps but then it drops out. That's par for the course with early RTL8153 chips. It's also a terrible dock and the seller has been banned from Amazon for one reason or another, so can add that on too.
On the other hand I have a more modern Yottamaster NVMe dock that I use with my Steam Deck and it works great. Surprisingly, it is almost fully functional on my phone except for display (obviously know why) and Ethernet. It's using the RTL8153B-2, but I can't get any data to pass over it. The r8152 kernel driver reports that it can't load the firmware, because the phone doesn't have any firmware from linux-firmware outside of what is needed for the hardware internally. Both the kernel driver and Ethernet system report when a cable is connected and the carrier is on, but nothing makes it over the cable.
The first dock you linked also has an RTL8153, so at this point I'm guessing newer revision RTL8153 support is just broken on the phones without the ability to load firmware for them. The second dock you linked inspires some confidence that it will have an AX88178 controller in it, but I've looked at docks recently on Amazon and ones that list AX88178/AX88179 are apparently silently subbing them out for the RTL8153 according to reviews. You're going to have to plug it in to your computer to check what the Ethernet controller shows up as.
Best course of action I can see is to either try to find a dock with an AX88178 in it if your second dock actually has an RTL8153 in it, or get an older USB 2.0 RTL8152 adapter since those are more reliable although that restricts you to 10/100.
It's a bit of an older model but I have been using an Aukey CB-C71 with a Pixel 7 Pro and previously Pixel 6 Pro with ethernet, USB-PD, USB keyboard, and USB wireless mouse. I have used USB PD with everything from the original Nexus 6p chargers to various Windows and Mac laptop chargers without issues.

I'm curious, do you know what chipset the CB-C71 uses? I have another adapter on the way from Amazon, if that doesn't work out I may try the CB-C71 or a device with a similar chipset.

RTL8153B-2, interesting that it doesn't have any issues.
I found an adapter that works: https://www.amazon.com/dp/B0BGHKLSPG?psc=1&ref=ppx_yo2ov_dt_b_product_details It is gigabit, with power port. It works without its power plugged in and the phone upside down on the powered pixel stand. I would still like to buy a real hub with gigabit ethernet for the P7P, if someone finds one.

That meets most of my specs. The problem is only 4k 30hz HDMI. If I want to use it with a 4k 60hz device that can use the HDMI output, (obviously not the crippled Pixel line) I would be downgrading.
