I agree, this may be a custom job.This depends on your CPU but, it looks like you can run 4k on the Intel HD 4000 graphics card at 24Hz. You may have to set this up as a custom resolution.
24Hz will not be a great experience so, although possible, I wouldn't recommend it.
@sizzling Yeah, it doesn't look like 4k is 'officially' supported. Even more reason to not do it.
