The only solution is to buy a cheap android tv hdmi stick. If you compare prices is cheap to buy a cheap lg webos tv+HDMI android stick than others fully integrated android TV with 2-3GB of ram. Mostly cheap android tv came with 1GB or dual core processor, which is pretty slow, lg webos is pretty fast for the processor that the LG tv has.
Also cheap android tv are not frequently updated based on my experience. If you plan to install "3rd party players" and you want 4K and HDR xiaomi tv box is about $50
