How big a monitor is too big? Trick question; there’s no such thing as a monitor that’s ‘too big’. However, the bigger the screens get, the higher the price rises, until you’re looking at some pretty eye-watering MSRPs for some of the largest screens out there. So, when one of these screens goes on a huge discount, you’re essentially getting all of the benefits of a huge monitor without the downside of a giant price tag.
