I have a 4k Monitor that is capable of 2K (WQHD) and tried my Galaxy Note 9 with the DEX Pad and also another 3rd party USB-C HDMI dongle and am unable to get anything but 1080p resolution. With my giant monitor, this just won't work. The option in DEX settings for resolution of WQHD remains grayed out. I noticed this on my Note 8 as well, bummer. I'd like to use DEX but this one is a show stopper for me.

Goodmorning everyone
I bought an HDMI adapter, it works fine with Note 8.
There is no need to make any changes, as it is already set up to work with both DEX and HDMI Mirroring.
Reaches a 4K resolution,tried and fully functional.
Works with S8/S8plus/Note8

Is this using the full 4k resolution, or outputting in 1080 and then upscaled by the monitor? Does this work with mouse and keyboard also?
I'm thinking of this as a Dex replacement that is more portable.
this adapter is self-tuning to screen resolution,it can not support mouse and keyboard.
To do that You will need the Dex.The second native and 1080p and it suits the screen
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.
Hi all,
maybe you can help. I KNOW it worked for me before but now it does not.
Dell 27" Monitor. 1440p native. Works perfectly with the macbook pro.
Note 9 + the original Samsung EE-HG950 USB-C to HDMI adapter. The Note9 can do 1440p natively without a DexPad/Station.
Yet now Dex capped at 1080p. I know it did worked before. But now refuses.
I tried 3 different HDMI cables. and 3 different USB-C to HDMI/DisplayPort adapters as well.
No go. I am sure it worked for me before. Dex Resolution grays out the 1440p option.
What should i do?
Does samsung tries to enforce me to buy the Dex Cable now?
Note 9 Firmware:
PDA- N960FXXU2ARJ7
CSC- N960FOXM2ARJ1
Thanks Tal
Any updates on this?
Hi guys
I got a little big issue with dex and my TV, My TV is FHD , when I connect my S20 FE wirelessly to my TV and bring up dex, The output is FHD
But when I connect it uGreen Type-C to HDMI, Dex says that the monitor/tv resolution is not supported by dex, and the output is 1366x768.
I thought the cable has issue, and tested it on a samsung monitor, and works perfectly on FHD, so the cable is OK.
May anyone please help me with this issue ?!
check the settings on your TV, maybe there are different input settings for HDMI or one of your ports is different from the others. google your TV's model and the phrase HDMI resolution etc.

Hi , I did that all hdmi ports are FHD , and tested them with my laptop hdmi, all of them shows FHD. I think dex uses a special standard , that my tv cant support it.
Samsung DeX HDMI max resolution is only FullHD (1920x1080)
I’ve got Plugable UD-CAM dock and it works perfectly fine with my Dell Latitude 7480 laptop and USB, Ethernet and WQHD (2560 x 1440) Dell monitor. Pretty much the same is applicable to my Samsung Galaxy S9 with only 1 exception - HDMI resolutions above FullHD (i.e. 1920x1080) are grayed-out in...

Hi i was planing on using my phone as an Android TV Box for 4K movies, emulators, Android games and streaming from GeForce Now on my 4k Sony TV. Would be awsome to be able to use my old phone as an sort of Nvidia Shield.
I have an 4K 60hz USB-C to HDMI dongle but when i connect over HDMI i get the sharp "4K image" but with the phones aspect ratio and black bars, if i use DEX it uses the whole screen but only in 1080p.
Imagine a custom rom made to repurpose old phones into an entertainment hub og even a low end desktop with Android TV Launcher or a more desktop like launcher like DEX.
The S21 supports DisplayPort over USB-C up to 4K 60. Basically you can use a Type-C > HDMI adapter
Thats the problem, when I use a USB-C to HDMI the TV shows 4k resolution but with the phones aspect ratio so I get black bars.
I was hoping that it would be possible to disable the phones screen and only use external display and that way get the correct aspect ratio.
