[SOLVED] What size for gaming? What size for secondary?

[Pixel2k2k]

So guys, im considering buying a second monitor, im gaming on 27inch 75hz lg monitor, and i wonder what size should my secondary be, it would be used for non gaming activities, internet, obs, etc.
My current 27 inch main is in a distance a bit longer than my arms can reach and i dont actually know if thats good for gaming if its only 1080, so im considering to have the main one as my secondary and 24inch as the main but i need advice.

In general Monitors look best (aesthetics not visuals) when they are identical. As for usefulness ANY second monitor is an amazing transformation and i still use a crappy 1080p 21in LG monitor with my 27in IPS BenQ. In general above 24in you would be well served by moving up to 1440p because the pixel density gets very low at 1080p but that's up to you and the abilities of your rig. Just a note when you go down a monitor size you will find yourself involuntarily leaning in to compensate.
