I think you might actually want to search for products that are positioned as "monitors". Some of these are pretty reasonably priced and should offer what you're looking for.
For example, I am using an LG LG43UD79 currently. This is a 42.5" IPS 60hz 4k "monitor" at a decent price (I think I paid $399 at costco.) it has HDMI and USB-C inputs, but no smart functionality at all, no tv tuner, etc. The color and picture are pretty good after calibration. I normally use the monitor for programming, web browsing, chatting, etc but also do some very light gaming and it is fine for that.
I recommend this monitor and am hopeful that there are some more modern equivalents of it when I inevitably upgrade in a few years as I love the large monitors for getting work done.
