Ya, agreed but he has made a vital mistake.
He bought a silver mscaler, they don’t upscale to 768khz, only 705khz as they are missing the onboard memory controller.
Without having an onboard memory controller, the silver mscaler can only go as high as 705khz. The memory controller on the silver mscalers is located on the pcb not the cpu and because so, the instructions are sent back and forth between the memory controller and the cpu causing delays which hamper realtime upscaling/playback at 768khz. It also lacks cache levels 3 and 4.
The black mscaler has both an on chip memory controller, making sent instructions more or less instant and, it has all 4 cache levels, L1 - L4, which allow it to keep up with real time upscaling and playback at 768khz.
Do not believe me as it’s not true! Smiley face here.
