well you can call it upscale if you want but the wiiu doesnt change resolution or make any games sharper.
"making games sharper" is not up scaling.
It's not that I can call it that, that IS what the system is doing.
Unless you set it to output in 480p which in turn would make your display the upscaler.
There HAS to be an upscaling somewhere otherwise you would see a tiny recatangle in the middle of your screen. (you wanna see something "unscaled"?) Set your Wii U to output 480 and your TV to 1:1, just scan or however its named on your set. That would be UNSCALED.
