What is the picture resolution with PC differently than mobile phone?

I looked at a Lets Play on Youtube to make an decision is the game Good

On the laptop one can say the game is definitely good and on mobile it was the same video, the resolution was miles better

The game has been released for the Wii U

Same resolution. Same number of pixels… 10 times larger display…

Would be good if you specify the mobile phone model and what resolution your laptop shows, probably. Does the device that made the game look better have the higher resolution (see HD, FHD, WQHD, 4K)

Phones have a larger pixel density than screens

for comparison:

Mobile ~ 300 pixels per inch

Screen ~ 96 pixels per inch

Reasons for this could be:

The pixel density is much higher with the mobile phone, often with over 400 dpi, with the PC perhaps under 100 dpi, since both screens probably as resolution Full HD have.

In addition, cell phones often have better displays, typically IPS and OLED panels, which have much higher color space coverage and display, so that colors look much crisper compared to a TN panel monitor.

Your phone will have a higher DPI, so it looks better.

But it can also be, your laptop actually has a bad resolution, or the resolution was set incorrectly on Youtube.
