The low resolution of your game on your graphics card could be caused by a few different issues. The most likely cause is that your graphics card settings are not set correctly. The most common problem here is that you need to update your graphics card drivers to make sure they’re up to date and working optimally. This can be done easily with a few clicks in the System Settings panel of Windows.
Another issue could be that the game itself does not have the capability to display higher resolution settings. Some games simply do not have the capability to go beyond a certain level of resolution because of hardware limitations. If this is the case, the best solution is to find a game with a higher resolution setting.
Finally, your hardware might not be capable of displaying higher resolution settings. Graphics cards have certain specifications as far as their maximum capabilities, and if this is the case, then your only option would be to upgrade your graphics card. Investing in a more powerful graphics card will increase your game’s resolution settings.
In conclusion, the low resolution of your game on your graphics card can be caused by many different reasons. Most often the issue is that your graphics card settings are not set correctly, or that the game itself does not have the capability to display higher resolution settings. If it is neither of these two, then your graphics card may not be powerful enough to display higher settings, in which case you will need to upgrade your graphics card in order to experience higher resolution settings.
