Connect laptop to 24 inch monitor?

I connected my laptop, the HP 250 G7 with integrated graphics card (Intel UHD Graphics 620), to my 24 inch LG monitor (lgd 24mp56hq-T). Now I have the problem that the picture does not look really good despite the highest resolution set. Although the 1920x1080 seems to be displayed on the screen, the quality of the pixels seems to be worse than on the screen of my laptop or my other screen, which is only 22 inches tall.

Now I would like to ask if this "bad quality of the pixels" exists because the integrated graphics card of my laptop, the content just can't be displayed better on the big screen or if it is due to the settings of the screen or the computer and if This is what I have to change.

I appreciate every helpful answer.

On the one hand, the monitors are in different quality, on the other hand, the quality gets worse with increasing inch size since only the monitor is larger, but the pixel density does not increase.

This makes a 15 "TFT look better than a 24" TFT in the same number of pixels.

It's like a poster, from a distance it looks great, but if you stand close to the poster it looks 💩.

And yes, the Intel iGPU is a turnip.

Thanks, but I just had to fix the sharpness on the screen, now it looks good.

Supi if it was that easy. You never stop learning (mean me).
