Best option for streaming to TV?

So, right now I have been using my Nvidia Shield Pro to stream Steam from the PC to my TV, but I have become increasingly displeased with this because it seems to introduce a ton of lag. I know that this is from the Shield because I also have a Series X and it doesn't have lag.

Anyways, I decided to try connecting my tablet (OnePlus Pad 2) to the TV with an HDMI adapter and that seems a lot snappier and less laggy. However, there I have the issue that the HDMI is a mirror and the aspect ratio is the one from the tablet so it has black bars on the sides.

I'm wondering what would be the best option here.

A) Replace the Shield with a different streaming box that does the job better. I don't know of any of them, so I'd be open to suggestions.

B) Figure out how to get my tablet to change the aspect ratio when using the external display.

C) Replace my phone with one that can output HDMI at 16:9 on an external display and is good for this purpose (I am replacing my phone next year, current one can't do HDMI over USB C).

D) Buy a stupid long HDMI cable and plug the computer directly into the TV.

I would be especially interested in any option that would allow me to use that new codec that is supposed to reduce latency.

Edit: So it turns out that there was something going on with how my controller was interacting with the Shield. I plugged the dongle into the PC directly and it works great now. Hot damn.
