And u need search the refresh rate also. I got toshiba atv running 4k at 30hz and Sharp 630x running 4k at 60hz eventough the Sharp is way older than the Toshiba. Depends on your preference My recommend go for Sharp 6800x if u have the budget. I got both ATV now and still I use Nvidia Shield for ease of mind

No la on the shield also get the cheapest i can get on shopee also below 1k. The tv model I got is not top model but comes from old stock on a good price. The sharp 630x(no hdr) I think about 2013 model while the toshiba also only 49 inch and not a flagship model but currently broken now due to horizontal line. Waiting for replacement part
