In League of Legends, the resolution of lol is normal but the picture is blurry. You can refer to the following:
It may be that the player has adjusted the image of the subordinate video to low or even extremely low in the game options. You can adjust the character detail quality to medium, the environment quality to medium, the special effects quality to medium, and the shadows to medium, and that's it.
In addition, the color level, color gamma value, color brightness and color contrast under the accessibility of the video will also affect the picture. You can adjust the brightness to 30-40 and the contrast to 70-80 during the day and night.
