Oh that's funny, I have the same laptop with you!

I use fractional scaling hidpi (1.3x) and no issues at all. But coming from a 2015 MBP 13" retina display, I can definitely tell the difference, and the MBP was much nicer to look at.

I opted fro the FHD+ instead of the 4K screen in my Dell for two reasons:

- 4K is *WAY* beyond Retina, which is already very dense for me.

- I was afraid the 4K would drain the battery (especially on Linux)

I really hope Dell will offer a sane ~3K display (i.e. Retina levels) in the future and remove the burden of choice for their customers (at least where it's not needed).

Before you ask: no coil whine for me, but the thin rubber feet peeled off after exactly one year. This pissed me off on a £2K laptop.

Any coil whine?

I haven't noticed any particular noise from the unit. I'm in my late thirties, so if it is at the higher end of human hearing, perhaps those particular cilia are gone, but I'm happy. Placing my ear on the keyboard doesn't detect anything either.

It has been the better part of a decade since I've had a laptop with a fan, so that is a little bit different, but I only notice it under higher loads.

Yes, it exists. However it is my daily driver and I've all but tuned it out months ago.

It's really not as big a deal some make it out to be.
