I would like to share with you my setup which is like a dream come true. I have always imagined that one day I'll have single device that I will use throughout the whole day and now it finally is possible.

I bought an opened box HP Elite X3 Lap Dock of Ebay for 230 AUD in a pristine condition for my Galaxy Note 10+ (European, Exynos). Affter I have received it I had some trouble to connect my phone to the Lap Dock - the original HP cable was missing and the one from Samsung did not work. I finally figured it out - It has to be a USB C cable that will allow video transmission, quick data and power transfer - to sum up it has to be at least USB 3.1 Gen 1 that provides 5 Gb/s, 5V, 3A (Gen 2 provides 10 Gb/s). I bought https://www.amazon.de/gp/product/B01GGKYT7M/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 and viola it works!

It is almost a perfect solution - I have been able to switch from Windows laptop instantly, I have prepared a whole lecture with PowerPoint on this setup, I use it from time to time for gaming (love the PSP games and bluetooth controller). All is extremely compact, premium made and useful. The whole set combines: Galaxy Note 10+, HP Elite X3 Lap Dock, Amazon USB C cable, 8Bitdo, Samsung 45Watt Charger, and couple of extras like additional HDMI cable with micro HDMI adapter, USB C to A cable, USB C hub with HDMI, 2 x USB and USB C sockets and foldable bluetooth keyboard with touchpad. All of these fit well in a 11 inch Apple Macbook Air neoprene bag:D

Connecting the HP Lapdock to the TV with HDMI (using HDMI to Micro-HDMI adapter) and then connecting phone wirelessly with it allows to display on TVs without Miracast.

In order to get regular size font while using DEX I am utilizing MacroDroid macros: Receive Notification DEX App - Change system font to 1.2 and Remove Notification DEX App - Change system font to 0.8 (my default)

The known issues are:
1. Lap Docks speakers does not work - I had to change in settings of DEX and in Developer Settings not to route sound via USB and now when connected sound is played from the phone
2. Touchpad buttons are not recognized - it works perfect other than that (gestures, zooming, scrolling, two fingers for right button)
UPDATE
Audio via lapdock speakers works! - in order to make it work just plug in the phone to the lapdock without turning it on and then turn it on by holding battery button and power button simultaneously for 10 seconds until it boots. When its on in volume panel chose play via display device and enjoy B&O sound.
There is a bad news too - after updating to Android 10 the touchpad is practically unusable - they have change the way it operates and now it moves incredibly fast up and down an extremely slow from left to right - the only option is to use the phone as touchpad which luckily is very good.

The new whole set consists of:
1. HP Elite X3 Lapdock

You have to turn of lapdock first, give it a 10 sec after it has booted than connect it with a usb c 3.1 gen 2 cable (a short one, cables longer than 1 meter seems mot to work) and it should be fine. I am using a 50 cm UGreen cable, sometimes it is required to hard reset the lapdock when it does not pair properly by holding the power button for 10 sec.

An Update:

Finally audio via lapdock speakers works - in order to make it work just plug in the phone to the lapdock without turning it on and then turn it on by holding battery button and power button simultaneously for 10 seconds until it boots. When its on in volume panel chose play via display device and enjoy B&O sound.

Maybe we can send a request to Samsung to fix the problem with the touchpad because we are many users with it.
Anyone with the tab s (5e or 6). Can check if having same problem?
Thanks

Can you please check underneath your Lap Dock what the model number is?
E.g. V8H07UT#ABA or Y1M47EA#ABH, etc.

I am having the latter also with a European Exynos Note 10+ and I can't it to fully connect (no display).
Thanks!

I bought the HP Lap Dock V8H07UT#ABA for my Note 10+ Exynos (Portugal) and was never able to have it work. I bought many different cables but didn't change a thing. The same cables used to connect my Tab S4 (Snapdragon) to the HP Lap Dock worked flawlessly.
So you are very lucky to have a working setup!

Ok, I got seriously lucky.
Found the mainboard of the V8H07UT#ABA online, and it arrived today.
Replaced the mainboard of my Y1M47EA#ABH with it, and I now have a working Lap Dock with my European Exynos Note 10+. Happy camper here!

What kind of USB-C cable are you using? The one that comes with the Lap Dock or another brand? Is Developer Mode enabled ? Thanks.

Just now I have found one strange thing - I have change the cable I used with and older one which was working fine and now it did not - what did fix this issue was switching the ends of the cable the end that was going into lapdock went to phone and vice versa. I know it should not make any difference since these cables are reversible but it did mabye that will help somebody.
