It looks like the Dell Ultrasharp U2717D might be a good option for your needs, as it has:
- An IPS panel for accurate colour reproduction and good viewing angles.
- A thin bezel to make viewing more comfortable.
- 1440p resolution on a 27" display, which should look great with regards to pixel density.
- USB ports for any (my recommendation - less power hungry) external devices that you may want to connect.
Additionally, this monitor is currently on sale on Dell's website as well as on Amazon, so feel free to take a look!
