Ironically with these new consoles coming up, excitement from my end has been coming not from new game rendering technologies and fancy lighting techniques, but from the screens and displays themselves. 

I recently had the incredible experience of seeing a JVC DLA-NX9 projector play video games. My friend is a major cinephile and not much of a gamer. The only reason there was an Xbox One S on hand was because he rates it as a great 4k upscaling solution for 1080p movies, and because the HDMI input allows him to upscale even older stuff. He let me sign on and I downloaded FH4 and I was absolutely blown away. 

I've played Forza on my GTX 1070 in much higher native resolutions, max settings, with much faster framerates than on his One S. But the colours, the contrast ratio. Also the sound. I always thought headphones were best for gaming, but this is absolutely something else. Native 4k games content is obviously much better, and I was itching to see a sharper image, (if I had £17,000 to drop on a projector I wouldn't be playing on a One S) but there's a point which I hadn't imagined before, which was that great looking games are as much about the display technology as they are about processing and effects. 

I read a couple days ago on Forbes that the Series X/S will have Dolby Atmos and Vision, and the PS5 will have Tempest, which if its anything like Vision will also boast around 68 billion colours (exponentially more than HDR10 (8^10 vs. 8^12)) and equally good tone mapping and brightness. Amazing news, but only if you have the tech to take advantage of it. I had been preparing to drop my money on a 3070 or a Series X but I've just gone out and got a great deal on a 2016 enthusiast Sony VPL-HW65. 1080p for just over £1k. My PC will become my game pass machine for the foreseeable.

So that's my "next gen". Seeing the amazing colour and quality that had been there all along. I suspect that many people eyeing up a new console might also need to give some thought to their TV, if they haven't already.

Yeah, I'm looking forward to new display tech. Screens that take full advantage of the HDMI 2.1 spec at a decent price point have been frustratingly slow to arrive and I'll probably skip out on this year's models, but I'm looking forward to and expecting to purchase next year's.

I just ordered my first 4K TV ever. Took forever to save up for it and it's on the lower end. Now I shall see how my games look esp Switch. If they look really bad may have to shell out for an Mclassic I guess.

I am still waiting to get my hands on a proper 4k tv for myself. Like we do have a Samsung one but I don't play games on it.

I am trying to get one that is fap worthy for both PCs and consoles. Most likely I will wait until next year as some cool 4k monitors are supposed to come out.

Unless you have big bucks in 2020 you can only have two of resolution, size, colour quality and refresh rate. 

I don't want to make any grand claims about the best way to game. But the prettiest way is with size and colour - not resolution and refresh rate. As soon as Sony or LG get an affordable 4k TV to 120Hz.. that's when i'll go 4k.

I can personally afford to get the LG CX 48 OLED but right now, there's an issue with VRR that's affecting both CX and C9 tvs which if I am gonna spend that kinda money, I don't want issues like that.

The problem with size is that it is very dependent on how far you sit. If you are in a living room, then yea, bigger than better. For me, I do both my PC and console gaming on my desktop monitor so going anything above 48 inches is a bit of a no thanks for me. Personally I'd prefer a 32 inch in my case. Colour I do agree as long as the game implements HDR correctly.

But personally for gaming, having only excellent colours won't get me the smoothness of high frame rate and games are more than just about watching an interactive movie. I am willing to pay to get a great TV or Monitor but only if it delivers in all those areas to a fap worthy degree including as you said, Colour.
