Cubase 10.5 Video Player with 4k - Only showing one quarter of the picture

Hi there!

Having this issue over the last couple of monts:

My VideoPlayer is only showing 1/4 of the original video. (See the picture attached)

What I tried so far:

  • Updating my grafic driver
  • Updating everything hardware related
  • Updating Cubase
  • Mov as well as mp4

My stats:

  • Operating system: Windows 10
  • Programm: Cubase 10.5 (v 10.5.2)
  • Processor: Intel Core i7-8700K CPU @ 3.70 GHz
  • RAM: Corsair 2*32 GB @ 2133 MHZ
  • Grafigcard: NVidia GeForce RTX 2070 with 8 GB
  • Motherboard: ROG Maximus XI Hero
  • Monitor: 49" 4K Samsung

Get ER Media Toolkit and convert the video to ProRes.
