Desktop mode with poor resolution - Huawei P20 Pro Questions & Answers

When connecting in desktop mode to my TV LG full HD, I see icon too big but I'm not able to upload here the screenshot. I cannot find any possibility to change it into the settings.
Can anybody experienced same issue?
Thanks

I ran into that problem with a cheaper generic monitor and a cheap adapter. At first, I had the cheap XtremePro (generic from Amazon) and sometimes my monitior showed 480p, sometimes it was 1080p. It was weird, I had to plug it in the Samsung TV (1080p) and then go back to my monitor, it would correctly show as 1080p. When I changed the generic monitor to a Samsung, now it shows 1080p. But the adapter didn't allow me to plug it in and recharge my phone so I went out and bought a new adapter that does a great job.. recharges phone AND shows 1080p.

LG monitor, depends on the age, sometimes it doesn't read the phone very well or it could be the adapter itself. Upgrade the adapter to the one I recommended before changing the monitor.

Bought one and used it on Samsung curved monitor 28" everything is perfect 1080p signal.. Maybe as said it's the Adapter. Mine come with USB hdmi and USB c ports. Or maybe some configuration on TV ? Did u try on a monitor?
Mine I was able to charge and use the hdmi in the same time...

Today I made additional test. The result is that with 2 adapters, 2 TVs (Samsung and!LG) and 2 hdmi cables the resolution is always poor if I connect thru hdmi (icons are very big) with all combination adapter+cable+TV. But if I use a vga cable (one adapter has both ports), it works perfectly.
It seems a problem on p20 pro hdmi management.

Why does my HDMI dock work on SOME TV's and not others??? :(

So I bought the HDMI dock station. I had a spare HDMI standard cable. I bought a mini-to standard adapter. I plugged it all up (yes, with the power cable), and nothing... well, *something*... the TV says it was getting a 1080i signal, but nothing showed up. Television was bought new in 2009.
So I thought, "Well maybe it's the TV." So I happen to have a reasonably new (less than a year) HP 2311x monitor w/ HDMI input, and it says it's receiving signal but also shows nothing.
SO... I thought, "Well maybe the dock or the adaptor is bad." So I went back to Radio Shack where I bought the adapter. Connected everything up to a little HDTV, and IT WORKED. WTF?
Came back home, and it doesn't. WTF???
Anyone know why?
Ok I got the monitor to work after sorting out some issues with the HP support site. Looks cool to have the dock display on there.
BUT... the TV. It connects, then disconnects, then connects, then disconnects... meaning during a movie, I hear sound for a split second, then none, then sound again, then none.... never gets to the image. So it feels like something isn't quite detecting right on the TV side.
Any ideas? This is the adapter I am using with my standard HDMI cable: HDMI Female A to HDMI Male C Swivel Adapter. It works fine on the Radio Shack display TV with MY HDMI cable, and fine on my HP 2311x monitor.

USB OTG & OEM Samsung MHL HDMI HDTV Adapter Review

I bought a Cozy brand 5-pin USB OTG cable from the Samsung After Service Center in South Korea. Interesting enough, they didn't sell their own. So anyway, seems to work great. I made a video showing just how awesome a wireless keyboard and mouse works on the Note 2, particularly the split screen which can all be enabled and works so much better with a mouse.

I also bought an OEM MHL HDMI HDTV adapter (11-pin) from Samsung. I saw that they only had the one for the Galaxy S3, and I asked them if it was compatible with the Note 2 that I had. They said no, and that I should wait for the Note II one with a different model number. When I tried to buy it, they refused to sell it to me saying they didn't want to have to deal with a possible return. So knowing that I know more than who I was talking to having done my research, I came back a few hours later, saw a different person at the desk, and just told them I was going to buy the Galaxy S3 one. There are definitely some interesting things I learned with this cable. Seems to only want to do 1080i on my 1080p computer monitor over HDMI at 60Hz. But the upside is, 60Hz is very smooth. I keep hearing that on the S3, 1080p was choppy. I'm not sure if this is the case on our mighty fine Galaxy Note 2's with a faster processor and GPU.

Additional Info:
The Galaxy Note 2 supports both 11-pin and 5-pin micro USB connectors.
The USB OTG (On-The-Go) adapters only come in 5-pin, and works fine with the Galaxy Note 2.
I connected the OTG adapter to a USB hub, which was fine, and 2 different devices worked fine independently, but not both at the same time. My guess is, it is a power limitation that the Galaxy Note 2 provides through the micro USB jack.
If you want to buy a HDTV (MHL HDMI) adapter for the Galaxy Note 2, it is the exact same adapter for that Galaxy S3 that is 11-pin, even though the model numbers are different. 5-pin MHL adapters don't work on the Galaxy Note 2.
The HDTV adapter comes with a micro USB jack (5-pin), but although you may think it is a great idea to plug an OTG cable in there, it doesn't work that way. You MUST plug in your power cable. Why it was hard for me to find this info on the net or a youtube, I'm not sure. I guess I should have read the manual, but I think was more of a design thing. You wouldn't read a manual on how to plug in cables for plugging in HDMI cables and micro USB would you?
I can only get 1080i working at 60Hz even though I know for sure my monitor does 1080p. If someone can get it working with 1080p I would like to know how smooth it is. [email protected] is actually pretty smooth (I think 60 fps).
When outputting video, it only grabs the video stream, so it won't output overlayed subtitles on the TV monitor.
The Galaxy Note 2 gets pretty warm, maybe hot, especially because it is charging through the MHL cable that is powered.
Make Surround speakers work
Hi,
Just tried that with official Samsung S3/GN2 apdater.
That works great. I have connected it to my AV receiver and its indicates Video: HDMI 1080p Audio: PCM 44.1 khz 5.1 ch
Are you sure your video is encoded in 1080p ?
Also, got another question. In the settings menu (Accessory > HDMI audio output), I have selected "Surround" for HDMI audio output.
But when I play Dolby Digital HD video samples I found on the net, I do not manage to have any sound coming from my surround speakers. But my AV receiver detects a 5.1 stream.
I use MX Player, with codec ARMv7 NEON. And I've tried both HW and SW decoder.
If I connect the HDMI cable to my PC instead of my GN2 and I play the same files, then I get an incredible sound demo in my home cinema installation.
Have you tried that ?
Both the S3 USB OTG and HDMI work fine on the note 2, just confirming what you said above. Tried them on my t-mobile version and my friends at&t version.
You mentioned you could only get one thing going on your hub - you should always use a powered usb hub when using OTG cables. You will be able to run much, much more then the meager power provided by the device.
I've also been tracking sudden death through OTG cases - not one that i've seen so far has happened with a powered hub, all non-powered hubs or direct shot to the accessory equipment. I get the thought it has something to do with power flow from the phone out, but strictly anecdotal evidence at this point in comparing cases.
(sudden death through OTG is very rare, I wouldn't worry about it. Not using OTG because of it is like not driving your car because you could get into an accident.)
By mistake i brought samsung galaxy S3 tv hdmi cable now its not working with galaxy J2.

MHL to VGA

Are there MHL to VGA adapters available that are know to work with the 4x?
Or is MHL standardized enough that i can pick any MHL to VGA without any worrying about working?
I know HDMI is usually better but my HMD (tac eye) takes only VGA or SVideo (though SVideo quality really suxx, its only on for NV not for data).
Also I see some MHL to VGA adapters have a secondary USB port, can this be used only as client or could I somehow connect a pointing device to my phone?
If I were you i would take MHL to HDMI cable and then HDMI to VGA. Reason is simple. Sometime you may want to connect your phone to new TV so you will need HDMI as it is standard port.
Secondary USB port is microUSB and it is used to charge phone while conected to TV (at least thats how it works with MHL to HDMI cable).

Well, for me this would than look like: MHL-HDMI adapter connected to a HDMI-VGA adapter connected to VGA-"Proprietary HMD Port" thats in used space and weight more for the adapters than for the phone and HMD. As i intent to wear this on my body thats rather not cool. Also the HDMI-VGA adapter will want some juice what will be an additional drain on my batteries.
The "VGA-"Proprietary HMD Port" is passive, so if I like the setup I will probably cut the MHL-VGA adapter open and attache the signal lanes directly to a fitting plug for my HMD.
Also I don't own a TV just a 30" WQXGA Dell Monitor with a Duallink DVI port its one of the old models that had only Duallink DVI, no scaling no DVI no VGA and no other ports.
An other issue would be how to control the phone when it in my pocket, how can I attache some pointing device and would this even work with android OS?
Or would I have to wait for an unlocked bootloader and this cool ubuntu on phone projects that provide a full ubuntu desktop?
PS: is the micro usb port on the adapter only used for charging or is there still a USB signal on it?

If i got you right, you want to control phone, connected to PC monitor, over HDM goggles?
You can try something like this https://code.google.com/p/androidscreencast/
It is a software that enables remote control of your phone over WiFi, so if your goggles work on PC it should work here to. It does the same job as the cable connection (MHL to VGA)
As for the MHL to VGA adapter you have 4 connectors:
1) male microUSB (one you connect to your phone)
2) female microUSB (charger or power supply, so it doesn't use phone battery)
3) female VGA (for monitor)
4) 3,5 audio jack for sound

Not exactly I don't want to use a PC at all. I want to connect the HMD (Vuzix-Tac-Eye-LT-Monocular) directly to the phone and use some pointing device or mini keyboard to control the phone.
I have the adapter and a problem,
the phone is only giving out its native screen resolution, my HMD cant handle.
How can I change the resolution so SVGA ?

USB-C to HDMI not working on monitor Omen 25 by HP

Hello everyone, I received my choetech 4k USB-C to HDMI adapter for my P20 Pro and it works on my samsung 4k tv but not on my FHD monitor OMEN by HP, does anyone have any suggestion? I tried everything and the port in which the phone is plugged is always inactive...
Have used tonnes of these over the years. Usually to do with power throughput.
For example my apple USB-C connector works perfectly on anything without additional power, star one doesn't work at all.
Probably a power issue.
Nothing you can do
I had to try three different adapters until I found one that worked

HDMI Output Resolution Change

Hello
I Bought this adapter from aliexpress
https://www.aliexpress.com/item/4000504201626.html?spm=a2g0s.9042311.0.0.27424c4dlK6U7y
It all works fine the Ethernet port is recognized and all the USB ports work and it allows charging through the adapter.
HDMI also works when plugged in the side USB-C but the resolution is the same as the phones.
So when I connect to a regular 16:9 TV/Monitor it has big black bars
As far as I can see the dock allows for the resolution change
Is there a way to change the output resolution or do I need the official dock to do that?
