Dude, next time ask, don't make assumptions. Now to figure how to close this thread. No points or best answers, because with respect there were no best answers. Maybe the type of monitor I'm looking for hasn't been engineered yet. But I'll keep searching my own, as I've been doing.
Maybe next time provide more details about what you are actually looking for so that those providing you with free tech support don't need to make assumptions.
What they said was accurate, "4K" is referring to the horizontal resolution of a screen with a 16:9 aspect ratio, typically 3840x2160 pixels, so there's no real thing as "Ultra Wide 4K". The "Super Ultra Wide" screen you linked to in your first post only offers half the pixels of 4K, basically like if you cut a 4K screen in half horizontally. And due to the extreme aspect ratio, while it's significantly wider than your current screen (by close to 70%), it's also around 15% shorter, which isn't all that much of a difference, but is something to keep in mind. Overall, the screen area would be around 43% larger than what you have, but with half the pixels, the image wouldn't be as sharp.
The first screen that Hang-the-9 linked to in the first reply is the same size, but at 5120x1440 resolution. So, 33% more horizontal resolution than your existing screen, but 33% less vertical resolution, working out to around 11% less total pixels, but relatively close to the resolution of a 4K screen overall.
The one Glenwing linked to offers the same vertical resolution as a 4K screen, but more horizontal resolution, making it "Ultra Wide" (21:9) rather than "Super Ultra-Wide" (32:9). That does give it 33% more pixels than your current screen, though in terms of total screen area, it's actually slightly smaller than what you have due to the difference in aspect ratio, being a little wider, but a little shorter as well.
In any case, unless you have graphics hardware capable of handling higher-than-4K resolutions at more that 60fps, it's arguably kind of pointless to look for a screen with those specs. Cyberpunk is probably going to be rather demanding, especially if enabling graphics features like raytraced lighting effects, so even with something like a 2080 Ti, pushing native 4K at 60fps will likely be a bit of a stretch with the graphics cranked up. Having to turn the graphics settings down just to make the image slightly sharper at a higher resolution without significantly hurting performance seems kind of counterproductive to me. I would personally rather take a lower-than-4K resolution with a high refresh-rate rather than struggling to get decent frame rates at native 4K or higher. I guess you could use some form of upscaling to improve frame rates though, and just use the native resolution for less-demanding games and other tasks.
