Question USB-C to HDMI doesn't work – blank screen…. - Google Pixel 7 Pro

Hello, why do 2 different USB-C-to-HDMI cables NOT deliver any signal to the beamer? I used 2 brandnew cables (from Anker resp. Warrky), but the screen remains blank, as if nothing had been connected. On the other hand, this Full-HD-Beamer easily shows signals from sat-receiver (HDMI to HDMI), DSLR (USB-A to HDMI) and laptop (display port to HDMI).
Connecting the Pixel 7 Pro via USB-C-to-HDMI directly to the beamer (not to a HDMI multi-plug), I see these messages on the Pixel 7 Pro, that don't seem as expected (re-translated to English by me):
- attached device charged via USB (while the cable description says, "no charging possible")
- device controlling the USB connection: Connected Device (meaning the beamer obviously)
There is no change possible, for instance it's not possible to set "This Device" (the Pixel 7 Pro) as controlling device. Also the use for the USB connection (like file transfer, USB tether etc.) can't be changed at all. It is all grayed out and fixed to "PTP" (picture transfer protocol), which seems not to make sense?
According to data sheets, the Pixel 7 Pro has USB-C 3.2 Gen. 2 – and according to the cables' descriptions, with this the signal should go from mobile to beamer.
Do you have any idea? Are there other devices, perhaps even wireless? Thanks!
PS. I mainly would view mobile photos and Youtube videos. Audio would be transferred on a separate Bluetooth connection.

The phone doesn't support it. You can only use a displaylink device and it's a ****ty experience.
The pixel 8 will include displayport and should support HDMI adapters.

You could use a Chromecast for that, and they are inexpensive. I think you would need to send audio from your projector (I think that's what you mean by "beamer") though.

I was disappointed a phone in this price point didn't include MHL.
I use an hdmi adapter bought from best buy called ( J Create Adapter). App on playstore.
Best $29 adapter with unnoticeable latency..

Hi all, thanks for clarifying info, photos + screens!
It's disappointing indeed that you can't use a simple USB-C to HDMI adapter.
I will look at Chromecast and at that Best Buy adapter, if i do get it in my territory.
Yes, with "beamer" i meant projector.

Anyone knows if there is a change that Google enable a kind of desktop mode on pixel 7 pro if the 8 does support it? From what I understood the hardware can support it but it misses something in USB driver am I right? Or I'm dreaming and will be forced to switch to the 8 to get the feature?

ethernet port connection - is it possible?

ive done some searching but cant seem to find answer
i want to know if its possible to get some sort of adapter that would allow the diamond to be connected to an ethernet cable. Ive seen some adapters on ebay to allow you to connect a standard size usb input to the mini usb port and then i found a usb to ethernet port. would this work?
i want to be able to use the phone to check network connections and other basic things without having to carry a laptop round with me
any info would be much appreciated
HAve you finger something out? Got the same problem found some converters usb to rj45 but, lets say, in Poland it's not so cheap (I mean - the adapter) so I have to be sure to buy one.

I highly doubt windows has drivers for that built in
If you would boot a competent linux kernel talking to /dev/eth0 would probably do the trick though.

Xoom and USB audio devices.

hello Xoom owners,
Xoom uses USB OTG but I'm curious what capabilities does it really has.
What's more - Android 3.1 supports it's host mode.
Have anyone tried to plug a USB audio DAC/AMP/ external audio devices to your Xoom?

Did you have any issues using the Fiio DAC/Amp with the Xoom?
Thanks

I tried plugging in the Korg nanoPAD and Serato. Both devices powered up but that was about it. I'm not rooted so I can't easily debug to see if the OS recognizes them even. Would be awesome if Google could give HC some DAW/Midi love, and of course some quality apps would need to follow (sigh)
I am not terribly familiar with either device. Looked up the nanoPAD and it looks like it requires a midi over USB driver to be installed, so it wouldn't have native USB Audio support like say a DAC would.
Still haven't been able to get a definite word on whether or not a DAC would work.
Thanks for the report on these peripherals, interesting to see people pushing the limits.
host mode doesn't mean that any usb device will work. Currently the only devices with built in drivers are keyboards, mice, and mass storage. Anything else requires a driver.
Sorry to dig up this thread but has anyone found a USB audio class driver for the Xoom? It appears the Xoom must have one lying around somewhere as the dock uses USB only for connection, right?
Bumping this;
http://forum.cyanogenmod.com/topic/55393-usb-audio-and-digital-out/
It seems like the xoom needs a driver with usbaudio, then something to switch the output.

TV dock + controller dock?

Hi there!
Has anyone bought a dock that allows them to stream from the dock to the TV(wired), and used a gamepad (bluetooth connected) to android?
Scenario: go to a hotel, plug phone into dock, connect dock to wall for power, and TV to stream. Connect bluetooth gamepad to galaxy s 5. Play game on TV.
Sorry if I'm not explaining this clearly, I can try a different way.
Thanks!
Different solution: Just use HDMI adapter instead of dock. Specifically one with this code: EE-HN910FWESTA. I can only find it on the Samsung website, and it hasn't had any reviews yet. (Not sure if I should buy)

I bought a dock for the s4 with hdmi and 3 usb ports, as soon as I got the s5 I tried the dock with this device but it doesn't work.
I think the problem is that s5 doesn't have a dock mode
New information is known for this problem?
I have something like

i bought it for my s4 and it also works with my g900f the only problem is that the charging current is low, around 800mA, and at s5 because the charging port cover it cannot be pushed well and it doesn't stay only forced.
Does that dock has usb-otg? The problem seems to appear when trying to use mhl-hdmi and usb otg at the same time.

Looking for a USB-C Hub with Power Delivery

I'm looking for a USB-C Hub with Power Delivery, any good suggestion?
I saw Choetech's official Facebook were given out big discount codes of its USB-C multiport adaptor, so I sent a PM to request a code. Anybody used this one?

Did you find a suitable hub?
Hi everyone,
I'm also trying to find a hub with different connector like HDMI / USB-A 3.0 / Ethernet... but it's very difficult to know if they are compatible with the Pixel C.
Most of them are compatible with Macbook but to few information about compatibility with Android.
Does anybody make a list of compatible hubs for pixel C ?
https://www.amazon.it/gp/product/B01CJMQZF0/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
I have this one. Of course look on it on amazon.com
It has ethernet,3hubs that i use with usb stick(fat32) to move my docs and has powerdelivery to charge while u work. HDMI is not supported with usb c yet.
A list I don't have but for a little over $11, I bought me this 3-Port USB 3.0 LAN RJ45 Hub (eBay Item # 162126608654) in combination with a USB 3.0 Female to USB C (Item # 152382378772)
, and my G-Pixel C is a happy camper so far
Also, a friend of mine has this one with power throughput to host, works great on my Pixel C too

I have one, it works. The HDMI doesn't work yet: but it's a Pixel C problem: see here
These claim Power Delivery.

Does anyone know of a hub that doesn't briefly disconnect USB devices (mouse, keyboard, Ethernet dongle, hard drive, ETC) if the charger is unplugged?
I have some cheap hubs and they work but if I unplug the charger then everything disconnects for a moment until the tablet can reconnect with its own power. This is not great for thumb drives!
As far as I know, all USB type-C hubs are like this. In fact, I think It's the intended behaviour. Switching from charger to device for power necessitates a brief interruption.

Do you think a usb to vga connection would work?

Let me explain, I have a cathode ray television, a cube one, and I would like to adapt it as a second monitor. So I'm thinking of buying an adapter to convert its signal, the problem? my pc doesn't have another extra connector for a new monitor. After searching, I discover that there are cables that adapt usb to vga, and I more or less trace what you can see in the image. My doubts are, would this set work? regarding the USB to VGA adapter, I have not seen many tests on the internet of this working outside laptops, but it has a usb 3.0 connection, could it work in my computer?
I don't really care about the imput lag, I just want to know if it would work or because of the power load or something like that it wouldn't work.

Nice artwork. It should work.
It depends on your system recongnizing the "USB to VGA", which is an external video card.
You could do it with a internal video card if you have the slots.

I do not understand. The usb to vga adapter I saw was a cable, and to use it you had to install their respective drivers. My pc supports video cards, but because of my budget I can't get one yet. If I had one, I would just look for an hdmi to rca adapter.
Thanks for your answer, by the way.
Well, that little thingy with a plug has a frame buffer and all the things that a video card must have.
It's just that instead of connecting over PCI it connects over USB.

Oh, I get it. Thanks for your help
I'll point out the obvious that you can pick up a used LCD monitor for $10 at any charity shop.
The image will be better and you won't need the VGA to RCA adapter.
