Dear Owners of 4TCBK1X, can you help confirm or check the wired ethernet connection whether it is Fast Ethernet (100Mbps) or Gigabit Ethernet (1Gbps)?.. if you are using wired internet connection and your internet subscription (unifi, Maxis or Time) is more than 100 Mbps, then you can run Speedtest on your TV (you can either download speedtest from google play or run from web). If it's doesn't reach 100Mbps then it's FastE, if it goes beyond !00Mbps then most likely GigaE. I asked two different Lazada sellers, one says FastE, the other says GigaE... hmmm. Thanks for your help.

Got the answer.. FastE.. in the Thai 4TCBK1X review.. they took a picture of the ethernet connetion at 10/100.... hmm. It seems all 4K tv be it sony, samsung, LG and even sharp still use FastE. TQ

Yes but funny I read, if I'm not mistaken, the manual for Samsung 7400 recommends using CAT7 cable for wired ethernet connection. CAT7 is rated for 10G, kinda overkill for fastE (100Mbps) connection. I saw another manual from different brand recommending the use of CAT6. These recommendations can lead to different assumptions for users. You don't even need to use CAT5e.. CAT5 is enough for fastE. It's 2020 already, broadband products already offering way beyond 100mbps. Even powerline ethernet adapter can cater for up to 500mbps.

Did some quick reading, while there'll be no problem for 4k netflix or youtube but it'll pose some problem if you open 4k video from NAS or PC via local network.. bitrate problem.. even on 5Ghz wifi.
