Hello, have been looking for a 40-45" 4K monitor for a year. Looks like monitors in this range all have some kind of issues. How come? For those who have been using 4K TV in this 40-45" size range, how is your experience? What are the pros and cons of using 4K TV instead? Is it better to get one with HDR and 120MHz? I plan to mainly use it for programming, matlab, CAD, writing and reading pdfs perhaps with some gaming.
