What many don't know is that 4k resolution is widely considered as good as it gets, with 8k not being worth spending more money on because the difference is that slight. However, even 4k requires an outrageous computer and Internet connection, while 2k can be made to look almost as good using Sony's new HDR10+ standard. HDR monitors and TVs with the new standard are about to flood the market making 1440p (~2.5k) eventually the new resolution standard for anything but the cheapest TV or monitor. In video games and TVs, its always about faking it and this is about as good a fake as anyone could ask for, with even 144hz refresh rates and roughly double the brightness of current monitors and TVs. Using higher resolutions and more light, means these screens can produce a lot more subtle grays and colors, as well as, other details and more often make the screen look like a window and make everything appear more 3D. Four times the resolution of a 1080p screen which, combined with the higher refresh rates, makes aiming easier and eliminates blur in the background and similar problems. Prices on the better ones just now coming on the market should come down to normal consumer prices rather quickly over the next 3-6 years. Already you can find cheap Asian versions, with electronics being dirt cheap in most of Asia. Something like a geforce gtx 1060 is enough to run an HDR display for gaming, but you get higher frame rates and settings with more vram and a more powerful card with 6-8gb of vram being a minimum. A good rule of thumb is that if your current video card can play all your games at 1080p and 60fps, its good enough for 2k gaming. The difference is guaranteed to knock your socks off, and probably marks the end of the TV and monitor wars for the ideal flat screen replacement for a CRT. Black Friday is the best time to look for sales on such monitors or any expensive electronics, by having websites even email you all day long with offers up to fifty dollars or more off the regular price of something like a normally $350.oo monitor.
