Terrible lag when casting from my laptop

Community Member

I just bought brand new TCL android tv, with chromecast built-in. From the start, casting from laptop to the tv is impossible, it's ridiculously slow and unwatchable. No matter if I cast tab from chrome or whole screen, or a video from VLC player, it's slowed down. My internet and wi-fi are fast, and laptop casts everything fine to a Grundig tv, also android. Casting to TCL tv from my phone is also fine. I updated whatever apps and system apps I could on TCL tv, it just fixed the issue when chrome couldn't see the chromecast, but not the lag. Is there anything I can do to make it cast ok?
