Pc monitor vs tv monitor for gaming debate...

Some TVs, in game mode, can have input lag in the 10-15ms range and response time as good as <5ms. This may not be as good as gaming monitors but it is practically as good as many non-gaming regular PC monitors, plus outside of game mode these TVs are much better for, well, being TVs. As another note, OLED TVs have response time better than basically any LCD out there. (Granted OLED TVs aren't cheap, are minimum 55" at this time, and aren't totally ideal for gaming due to burn-in concerns, but just saying.)

Choosing the right TV is key and there's a few things to keep in mind:
-You need to make sure you get a TV with low input lag and as fast as pixel response as possible (note however that faster response time = more stutter for movies when using as a TV).
-Even the "good for gaming" TVs, are not going to be as good as PC monitors designed for gaming. (On the flip side, PC monitors don't typically make good TVs--not great for movies, video.)
-You're typically limited to 60Hz with TVs; many 4K sets that have 120Hz panels can also accept 1080p 120Hz signals, but then of course you're only gaming at 1080p.
-For competitive or hardcore FPS gaming, and for HFR gameplay, you're essentially going to need an expensive gaming monitor.
-4K gaming requires a lot of GPU horsepower (depending on the games you are playing and the settings and FR you are after, of course).
-1440p (on TVs that can accept it) doesn't always look so great on a 4K display because it's not an even upscale. 1080p is actually a better idea on a 4K display than is 1440p* because it's just an even/straight 1:4 conversion.
-If you're looking for something like FreeSync there are TVs that support this but at current time it's very few, therefore a monitor is again much better here as tons of them have FreeSync these days.

*Note some games have built-in scalers meaning they can output 4K while running internally (and thus requiring less GPU power) at something lower, like 1440p. This will look better on a 4K display as well as working better with more 4K TVs since not all can accept a 1440p signal. This is what consoles like PS4 Pro and Xbone X do, when they do "4K" gaming--neither can actually game at 4K, they instead do scaling tricks to get there.

Anyway I'm not really sure this is a "debate" per se. There's pros and cons to both. Typically speaking what works great for a gaming monitor doesn't work so great for a TV, so for mixed use (as a TV and for gaming) there's not much out there that's going to be "the best of both worlds". However IMO, for mixed use--combining both a lot of video duty and a good amount of casual gaming--TVs do better here because:
-they offer large sizes for relatively cheap prices--gaming monitors are generally a lot more expensive per unit size
-have modes (i.e. game mode, PC mode) that do away with the "TV processing" and reduces input lag to lower levels (some TVs are much better in this regard than others so read reviews that test for this); sometimes this mode enables stuff like 4:4:4 to be more "monitor-like" as well.
-when game mode is disabled they perform much better for movies, shows, etc.

On the other hand if you're not going to be using the display as a TV at all and are mainly focused with gaming, you should definitely go for a PC monitor more suited for that purpose. If you're looking for 1440p specifically it's better to get a native-res panel for that, and that would mean a monitor. If you're looking for VRR and/or HFR then again a monitor is better suited as stuff like 120-144 Hz inputs are common on gaming monitors and FreeSync, as mentioned earlier, is getting more common even on monitors that aren't specificallymeant for gaming.

In short:
If your main use is a TV? Get a TV.
If you have mixed use? Get a TV. (Get one with as low an input lag in game mode and as good a pixel response time as you can get.)
If your main use is gaming/PC monitor, or you're a hardcore or competitive gamer? Get a gaming monitor.
