Just passing to say not to use YouTube for image comparison , their 4k is really low bitrate.
- Already answered.
- Are you using a good quality new displayport cable, or the same old HDMI from your old monitor? 4k HDR needs a lot more data, and some cheap cables can't handle it.
- 🤷 Change to colors to what feels right. Unless you're a graphic professional, it's more about preference than some perfect standard.
- Yeah. There's a lot more pixels in a little more space. Each of them is smaller, and you may need to zoom on text-heavy apps that aren't optimized for 4k.
- Lots of new monitors default to a power saving mode where brightness is capped. You'll have to disable that to get the full brightness they advertise.
- On 27" screen size, I doubt you would have a sharpness/detail benefit in comparison to 1440p. Especially in online video.
- I do not see any mention of HDR support. Apparently it's a 10-bit monitor, but that does not imply it's HDR capable.
- I would not know nearly enough about calibration to tell you about this.
4 More pixels per inch (or per cm, whatever) often mean that e.g. text gets smaller. One of the many reasons I believe in the idea that 2160p screens only make sense (in some scenarios) when they are larger than 27". Otherwise you may start needing scaling even when your eyesight is better than mine. - No idea about brightness specs like that, so I won't comment on that.
- That is normal with a lot of monitors out there.
Also it doesn;t have USB-C has the spec sheet said
It would help if you gave a brand and model, and if it's new or used.
From what you said, it seems you got ripped off, but it might also be something as stupid as using an old cable which is drastically limiting you and a cheap and easy fix.
