I'm helping a friend build a new system. He has very poor eyesight, but teaches and does a lot of word processing and text editing on his computer. He recently found that the 4K technology gives MUCH crisper fonts that make it easier for him to do what he needs to do. So, he is purchasing a monitor that is 4K. Now we just need to build a system around this technology. He does zero gaming, so this literally needs to support web browsing, text editing, and similar things. What are your recommendations? Thanks
