Trust me, you need an ultrawide. It gives you a lot more room for multitasking. I can have a spreadsheet on one side of the screen and a Chrome tab on the right to reference something else. Or two Chrome tabs side by side. This one from LG has a 2,560 x 1,080 pixel resolution, is VESA mountable if you want to put it on a monitor mount, and uses an IPS panel for nice colors and good viewing angles.
HP 27F 27-Inch HD Monitor for $110 ($140 off)
If an ultrawide is too much, this is a fairly large monitor with a modern look. It’s an IPS panel, so you get a wider gamut of colors over VA or TN screens. It has a 1,920 x 1,080 pixel resolution, a quick 5 millisecond response time, as well as one VGA and two HDMI ports. It has positive reviews around the web, but one downside is it cannot be mounted. That may not be an issue if you’re OK with the stand, which doesn’t seem to take up much desk space.
Lenovo Q24i-10 24-Inch HD Monitor for $100 ($90 off)
This 1080p monitor with thin bezels has a strange stand that aims to offer a clutter-free look on your desk. You can attach the cables that come out of it onto an integrated cable management clip on the stem on the back to keep things looking clean. The screen itself is tiltable but not height adjustable. There’s an HDMI and VGA port, and it supports the VESA mounting standard. It’s not the monitor to get if you need the best color accuracy, but hey, it’s $100!
