I recently bought a smart TV running on Android and whenever I connect my laptop to my TV, and change the source, it starts flickering madly for a while, changing between my desktop and just pure black.
After a while (anywhere from 3 to 10 minutes) it just works properly, but today it started flickering again after working normally when I changed the volume.
The HDMI cable is brand new, and I tried all 3 HDMI ports on the TV.
Changing any display settings through Windows doesn't change the flickering at all.
Besides that, when watching a YouTube video it will sometimes slow down and speed up again to correct, even at 1080p (my TV is 4K). It is connected via ethernet and should be able to reach speeds of up to 12MB per second (100 Mbps).
Finally I couldn't get Windscribe (a VPN service) to work. When I turned it on my internet wouldn't work at all, and even turning it off wouldn't fix it. I had to unplug the ethernet cable and plug it back in, for it to work again.
I can't seem to find a way to run a software update or anything either idk if that might be causing any issues.
Any help is greatly appreciated
i'd try swapping out that hdmi cable just to eliminate it as a possible cause. i used to sell all kinds of cables, it's rare but i've seen bad batches of brand new cat5, cat6, hdmi, usb, etc. cables. if it's not the cable it could be the hdmi port. hdmi cables are heavy and put a lot of strain on laptop hdmi ports, which is why i rarely use them on mine.
i'm not familiar with windscribe but i'd contact their support people, it's what i do when i have problems with my vpn. i don't use youtube but try playing that video on another pc, maybe it's the video?
