I have offered this solution before. But I don't think you have tired it yet.
Move the laptop close to the TV's attach them via HDMI. You can even close the lid if you like.
Use a Wireless Keyboard and Wireless Mouse attached to the laptop. You can sit the keyboard and mouse anywhere in the room and move them around if you like. No Casting required. That's my setup in my living room. Works flawlessly.

Thank you for that suggestion, but using a cable is not an option. I like to live stream and I also like to use my computer while lying in my bed and I don't think they even make cables that long. I use the TV as an extended desktop, in other words a second screen so your suggestion wouldn't be applicable. Then there's the fact that it is supposed to work and I expect it to work.

 

You are not understanding, the laptop would be connected by a short cable next to the TV. You would then use a Wireless Keyboard and Mouse to connect to the laptop. You can lie in bed or anywhere else in the room and use the wireless keyboard and mouse to control the laptop that is next to the TV.

 

Actually I do understand. The prob is that the TVs are across the room so if the laptop is connected by a short cable to the TV then I wo not be able to see the laptop screen to use its screen.

 

The setup I suggested would be to use the TV (s) as your display(s).
This doesn't work if you still want to use your laptop as an additional monitor.
I would think that 2 TV's as displays should be adequate for your setup and not need the laptop screen.

 

I don't use the 2 TVs at the same time, one is in my living room the other is in my bedroom.......I still need to figure out why it keeps failing and what to do about it. Other people have set ups like these and it works perfectly fine for them I expect it to work for me too.

 

Re: Re: Re: Lagging smart view

Wow sure you don't want an even bigger TV lol. I fount that using a Google chromecast helped with screen mirroring. Problems i had when not using it was that my videos would pixilate and sometimes goes black then sometimes would be out of sync as well.

I don't use Google devices....and TVs well, they are a convenient method that is available to me and I don't mirror, I use the extend display option and Google devices besides being garbage are not compatible with much.
