Plain Evo is only type 1 which is too slow for 100mb/s recording, typical of 4k.
Evo Plus is type 3 which is fast enough.
However your problem may be with your playback software or the hardware. I can get problems even playing back 1080p, especially with my former graphics card.
Still pictures should not have any issues.
I just realized you didn't provide enough info, and I assumed.
Is this a video or still photo? If video, what resolution, frame rate and codec?
For stills, you mentioned ISO and shutter. Is this zoom or pro? If pro, what about aperture?
