Newegg is currently offering up a pretty good deal on a 27-inch 1080p monitor from Dell. Offering it for just $149, but you can save another $10 when you use the promo code EMCPRPY65 at checkout. This is currently selling elsewhere for $180, making this a great deal even without the promo code.
This monitor from Dell is the SE2717HR model, which is a 27-inch 1080p FreeSync Monitor. Which means it's going to be great for gaming. It does have some pretty small bezels, as you'd expect from Dell these days. And it also has a few inputs, including HDMI 1.4 and VGA. Now this is a 1080p resolution monitor, so it's not a QHD or a 4K resolution model, but it will still get the job done. It will also work really well in a dual monitor setup. Unfortunately, this model is not VESA compatible, so you won't be able to mount it, but it will still look nice sitting on a desk.
Newegg does offer free shipping, though it is a bit long. You can upgrade for faster shipping though, which is always nice. There are also taxes involved and those will vary based on where you live. So you'll want to check that out when you are going through the check out process.
