I can connect my surface pro to my tv with no problem. There is no lag and the picture quality is great.

First cable I found that actually supports MacBookPro 16" (BigSur OS) natively with the LG OLED TV . Tested 2018 and 2020 OLED TVs. Perfect for Video editing where you need a quick way to view 4K HDR output . Tested in Premiere Pro 2021 v15.2. - macOS BigSur v11.4 and Windows 10 DirectX12 now support HDR directly making this super easy. Applications like Adobe Premiere Pro also use this OS level HDR support . Just set Premiere Pro's preference for Extended Range.

This cable worked perfectly for what I needed, to drive a 4K 60Hz 10-bit monitor/TV (TCL 43S525 with HDMI version 2.0a I think) with a MacBook Pro 13 Retina (2017). I also tried it with my Samsung S10e phone to run DeX on the same TCL monitor, but the screen flashes black every few seconds. I think it's a problem between the phone and TCL TV, though, not the cable.I did have a problem with the first cable flashing black on everything I tried, but UPTab customer service was excellent and they sent out a new cable immediately!

Great value, compact, versatile device for leveraging mobile enjoyment of HD programming. Works as advertised. Be aware device display quality May have to be adjusted Depending on source media and source device. For example, Netflix HD output from my Dell XPS13-9370 Looks HD on a hotel LG HDTV from the get-go, but my Samsung Galaxy S9+ displayed dark and had to be corrected through TV display adjustments - an Easy Fix.

Works great! Finally I can play 4k HDR contents on my Macbook Pro by simply connecting it to a TV.
