Most basic reason one can tell is that TVs are ment to be viewed from distance and pc monitors from close range, TVA aren't good for eyes from close range or preffered to work with for long durations like computer monitors, you can get a verry good quality monitor at 22k. If you are only looking for a monitor with speakers in-built for your personal use then only. But using tv with pc practically aren't verry comfortable and looks awkward other than if someone is using it for show purpose(for bussiness work like in tv studios.)
