Pinnacle doesn't generally stock or sell monitors, because customers all have different needs/preferences, and they often have sales that make them cheaper than what we can buy them for, and they are not hard to install yourself.
Monitors have a surprising array of things to take into consideration:
1. We strongly recommend 27" monitors for any primary use. 24" is the smallest we ever recommend, and 32" borders on uncomfortably large if you're sitting right in front of it (at least at Full HD/2K/1920x1080).
A curved screen will help some if you want the larger 32" monitor (if you're going to be sitting farther away than normal, for example) - otherwise the viewing angle is just to sharp at the edges to see well. The up side is that at larger monitor naturally forces you to sit back and improve your posture. The opposite is also true: anything smaller than 24" will cause you to hunch forward so you can see it, which will lead to back and neck strain.
2. Height is important, too, for comfort & ergonomics. If you're on the taller side, you'll want a monitor with a built-in adjustable mount, or get a simple monitor stand (e.g. this), a monitor arm (e.g. this), or a wall-mount.
- Monitor stands and arms free up desk space, which is nice.
- Monitor arms can be wall-mounted or desk mounted. Both have their advantages, but they do suffer from the fact that if you bump them with any force, it can throw the positioning out of whack.
- Wall mounts (obviously) lock you into a height and a position in the room, making it difficult to rearrange or adjust for a new employee later
- Dealing with cords can get a little messy on wall mounts, because then you either have to put them inside the wall, or have them drape down, neither of which is simple.
3. Double-check your cables and ports to make sure you have the right cables/ports available on the existing PC. Almost every monitor has at least an HDMI port.
4. On 27" and smaller monitors, we recommend Full HD/2K (1920x1080) for most purposes, and not getting 4K because everything ends up very small and you just have to expand fonts and everything anyway. Plus, some applications still aren't written to deal with higher resolutions.
5. For most general uses, we strongly recommend 2 or 3 monitors wide rather than purchasing a "special" widescreen or curved monitor. While there IS a smallbezel in between each monitor, if you can live with that, you gain a lot of flexibility. It's usually cheaper and you usually get more screen "real estate" this way.
6. Brightness is important. We recommend a minimum of 250-300 nits (cd/m2).
7. We typically recommend matte over glossy screens - glossy is great for movies but will cause glare and fingerprints show really badly on it.
