I have a:
- Asus Zenbook UX430UNR laptop with latest Windows 10 Pro Version 1909
- Samsung UA55MU6103WXXY 4K Smart TV with latest firmware 1280.5
When I connect the Asus laptop to the Samsung Smart TV after 10 minutes it disconnects and it's hard to reconnect.
This is what I've done:
- Updated to latest driver for graphics card using Asus LiveUpdate
- Updated to latest driver for WiFi card using Intel Update download
- Updated to latest firmware for TV using inbuilt software updater
Updated to latest BIOS firmware for laptop using Asus LiveUpdate
Factory reset Windows 10 Pro
- Verified that the driver and hardware supports a wireless display using
dxdiag
Verified that the system supports a wireless display using an alternate method (
netsh wlan show drivers
command in a command prompt)Tried a LG V30+ Android mobile or Google Nexus 7 tablet device on the Samsung TV. This works fine.
- Tried connecting the Asus laptop to a different LG webOS UM7600PTA smart 4k TV. This works fine.
I've spent a few hours on Microsoft Directly support; Samsung TV Support and Asus support.
I've asked for support on the web here:
- This is my Microsoft Windows 10 Feedback hub report.
- This is my Product Review question perused by Samsung representatives.
- This is my Asus Zen community support forum post.
Any suggestions?
The relevant hardware:
- Intel® Core™ i7-8550U CPU @ 1.80GHz
- Intel® UHD Graphics 620 with latest drivers 23.20.16.4973 dated 2018/02/28
- Intel® Dual Band Wireless-AC 8265 with latest drivers 20.70.13.2 dated 2019/09/10
- Samsung UA55MU6103WXXY 4K Smart TV with latest firmware 1280.5 connected to Wifi Router on 5GHZ band.
Update 2020/01/03
- Updated Intel® UHD Graphics 620 to latest drivers 20.70.15.1 dated 2019/12/31
- I forgot to mention. Samsung HQ had me connect both the TV and laptop to my mobile hotspot. They didn't specify the frequency band but it was also 5GHZ.
- Samsung TV repairmen (Video Factory Electronics) came out but only tested their Android mobile to my Samsung TV which of course works as I"ve already told Samsung HQ. There was not good communication from Samsung HQ and Video Factory.
Still has issue.
