I can't answer that with 100% assurance Bill. That is 4K streaming. All I can say is I have watched full 1080p videos from YT and Netflix for hours with no buffering or pixelation. The Chrome OS code much simpler than Windows, so the slower processor can handle it. I absolute love this Acer. Fantastic picture, no hard drive to burn out, no soft wear to buy, no spy/mal wear. Just the perfect product for consuming the internet.
