Macos 27" 4k. Is this really a problem?

Question

macOS

There was a need to add an external monitor to the macbook.
Macbook pro 15 2013, integrated vidyaha.
I read all sorts of things on the Internet, as a result, there were several questions left without a clear answer.
A lot of places write that it is very desirable for dpi for makosi to be a multiple of 110.
At 27 inches, this comes out to 5K.
4K in dpi is not a multiple of 110.
But 27 "5k is inhumane for the price today.

1. So the question is - does 27" 4k really look bad on a Mac and is it better to take 2k or is it all purely subjective perception?
2. Will a macbook pro of 2013 with an integrated video card pull a 4k monitor in principle or not?

Answer 1

In short - you can connect a 4k monitor. Another question is whether it suits you. Therefore, you don’t even have a question about 5K.
But 30hrz is clearly not what you want from a monitor. I had discrete graphics, but even there, I did not connect more than 2 1080k monitors.

HDMI video output (different results on DP)
Supports 1080p resolution at up to 60Hz
Supports 3840x2160 pixels at 30Hz
Supports 4096x2160 pixels at 24Hz

I have 4K 28 inches samsung cheap, through the application and DP I managed to run it in HiDPI 4k 60hrz mode, but I have m1 macbook pro. And yes, 5K would be better, but we have what we have.

Ravings of a madman.

MacOS at 27"4K looks great with scaling "like 1920x1080". Font size will be appropriate.

Support for 3840-by-2160 resolution at 30Hz
30hz won't be very good (
