Amazon has the Samsung UE510 4K Monitor on sale today for just $219. This is part of Amazon's Gold Box Deal of the Day, so this is good today only. Additionally, this is a certified refurbished model. While you won't be getting the warranty of a new monitor, it does still get a manufacturer warranty, should anything go wrong here.
The Samsung UE510 is a great monitor to pick up. This is a 28-inch, 4K monitor, so it's definitely a good one to upgrade too. This monitor has a few ports on the back to connect your laptop or desktop to this monitor. That includes VGA and HDMI, so no matter how old your computer is, it can still be connected pretty nicely. This monitor does also have a pretty decent speaker here, so you don't need to worry about getting another speaker to use on your desk here. That's a pretty good thing for those that do a lot of multimedia on their computer at their desks. This is also a pretty good monitor for using for gaming. And that's because of the 120Hz refresh rate, and it also has a really good picture, which is definitely good thing for gaming these days. Remember this is good today only, so you'll want to grab it before it's gone.
