4K monitor rec to pair with 13" 2015 Macbook Pro?

[pinkoos]

Hi, I'm looking for a largish (at least 27") 4K monitor to pair with the used 2015 13" Macbook Pro I got.

Since this is the old design MBP, there's no USB-C, etc.

I haven't been in the monitor market for awhile so curious what are the makes/models to consider these days?

Thanks
