most people go for monitors for the refresh rate.
there's hardly any ghosting to speak of when jumping to a high end monitor-4k or otherwise.
but if you're not looking to play a game competitively, there's hardly any reason to go for a monitor; at least IMO.

at home I'm using a 55"KS7000, which I'm sitting about 2 feet away. the size takes a little bit of an adjustment, coming from a 50"W800b, but feels just right after a day or two of gaming.

back in my hometown, i recently bought a "gaming" monitor which is fairly low end, but still something alot of "pro gamers" claim is better than a TV.

I'm not impressed.

Something about having the size of the screen vs a 27" monitor...it just doesn't compare.

anyway, as others have mentioned; if you're going to upgrade, be sure it's HDR enabled. don't just look at the resolution of the screen.
There's a reason Sony pushed HDR instead of 4K when announcing the PS4Pro.
I find this very odd.
On my monitor I had to bump up my control sensitivity up 2 notches-from medium to very high before i can feel as comfortable on the monitor as I am with my TV.

no idea why..it has nothing to do with the frame rate either, the controls just feel way more responsive on my TV.

I have finally bought a 4K TV, to be exact it's a LG 43UH610T, at a very good value/price from Lazada. All I can say, to those who said better pair the PS4 Pro with a TV than a monitor, you are absolutely right! I tested it last night, I was very impressed! The HDR thing is amazing. Luckily I have one game that supports it, which is Uncharted 4, and the difference is very obvious. Some settings need to be done on the TV itself, or else the HDR is disabled by default. And on the PS4 too, have to set some stuff in the Display section. Got 2 kinds of HDR though, one is RGB and the other is YUV20. I pick the RGB one, but still have no idea what is the difference between these two.

Anyway, I hope more titles will come with HDR support in future. This TV is a worthy buy. Hopefully this thread can provide the info to those who wish to buy PS4 Pro in future but face similar dilemma like my situation here. Just go for a 4K TV..........you won't regret it!

Nice one bro. How long did it take to deliver to your home when you buy from Lazada?

Monday ordered, Tuesday received. Very efficient.

Seriously?? That's so fast. 

Thanks for the info bro. 

As expected, HDR option is unavailable when using 4K monitor because there is no 4K HDR monitor at the moment.
But the most important to look for a 4K monitor is that it supports USB 2.0, otherwise, you won't be able to get the 4K RGB or YUV option in PS4 Pro video settings menu.

But according to this guy, it's already looked marvelous even without HDR.

He's using a Philips BDM4350UC 43-Inch Class IPS-LED Monitor 4K monitor.

I think u must be referring to HDMI 2.0 and not USB 2.0, a typo error there perhaps? And yes, HDR is indeed a big deal when it comes to 4K and PS4 Pro. After I have tested and seen what my PS4 Pro can produce on my recently purchased 4K TV that has HDR support, I was really impressed. Of course the game itself has to be able to support it and I just lucky enough to have one of them, which is Uncharted 4. The graphics and color are so beautiful and realistic, especially on tropical jungle scenery location. For a non-gamer who happens to be around while I'm playing, she also shocked that how come a videogame can look so realistic and even asked whether or not I'm playing a game or watching a movie. I certainly looking forward for more titles to support HDR functionality in future, especially AAA first party titles.

You are welcome. And yea, I was quite surprised also that they could send such a huge item so fast. They must have got stock ready in hand or something awaiting to be sent anytime somewhere.

Bro, how is the TV? Are the colours and brightness ok? I'm thinking of getting the same model as you. How's your review on it so far with PS4 Pro?

The TV is superb, especially when I got it for that unbeatable price. I was using a LG 43" also before this, but it was a Full-HD model (43LF570T). Watching HD and FHD stuffs, I'd say, can't see or tell any difference. Both are very much the same. It only shows a real huge difference when playing HDR content, in which for my case is my PS4 Pro running a HDR supported game Uncharted 4. If you have a big room with long viewing distance, get bigger size, then maybe you'll see more difference. Unfortunately my room is small and viewing distance is short, so I can't get bigger size model. For 4K, usually people go for 49" and beyond.

Alright, now I know, TV it is then, for my PS4 Pro. I haven't really seen what HDR is all about yet, but it seems that everyone is talking about it when it comes to 4K TV, so it must be important I suppose. Guess I just have to wait until I get a 4K TV only can see it for myself what it is all about. Thanks man.

Hmm....this I frame rate thing I hardly notice. I did try plug it to my living room TV, which is a 32" 1080p, and for some reason, I feel the picture quality is better on TV, and color also looks nicer on TV. Maybe my monitor sucked, I'm not sure. It's a cheap Viewsonic 27" 1080p monitor after all, so this is why I'm thinking of changing it, and 4K monitor (or TV) comes into mind.
