Understanding 4K Resolution vs 4x Upscaling
The image upscaler 4K applies 4x magnification to your input dimensions — not a fixed 3840×2160 output. A 1000×750 input becomes 4000×3000 (exceeding 4K). Input must be at least 960×540 to make image 4K after upscaling.
Capabilities
4x = Input × 4
Each dimension multiplied by 4, pixel count increases 16x
True 4K Needs 960×540+
Input must be at least 960×540 to reach 3840×2160
Max Output: 16384×16384
Pro/Business support up to 268 megapixels
