Use GPU scaling instead of monitor scaling
Enable integer scaling if available
Set the monitor to its native 4K resolution
Use the display’s sharpness setting carefully
Try a higher-quality upscaler in the GPU control panel
Use games or apps with built-in resolution scaling
Increase render scale above 100% when possible
Use anti-aliasing to reduce jagged edges
Prefer 1080p content with good source quality
Avoid stretching non-16:9 content to full screen
Use a lower viewing distance
Choose a 4K monitor with good scaling behavior
Keep text and UI scaling adjusted for readability
Update GPU drivers
Turn off unnecessary image processing on the monitor
Use a 1440p or 4K output mode when supported by the app
Consider using DLSS, FSR, or similar upscaling features
