How can I make my quad monitor setup more ergonomic? (And cool as f*ck)

Hey guys, I trade futures and have just got my quad monitor setup, which has helped me a lot in my trading, but where it does not help is the ergonomics of it. Being that I plan on doing this for many years to come, how can I setup my quad monitor set up to be as ergonomic as possible?

I have 4 asus monitors. I fucked up on thinking I had 28” for the first two, so I ordered two 28” monitors and had already two 27” monitors.

So top 2 monitors are 27”, bottom 2 monitors are 28”.

Questions: - what are optimal screen settings so that they protect my eyesight?

- do “computer glasses” or blue light blockers actually help with eye strain? If so, any recommendations? (Not so concerned with the sleep effects)

- Should I lower my setup so that my eyes are naturally aligned with the center of all 4 monitors?

- is 27”/28” too big for an eye friendly quad monitor setup?

- How much backlighting do I need? What are the most ergo friendly ways to achieve decent backlighting as to not strain my eyes? I just have a shitty clamp work light more suited to a garage attached to the main post of my quad monitor stand pointing towards the wall.

- What are the best ways to cable manage all 4 monitors without creating clutter behind the screens or behind my computer which is on the floor?

- I know 4 monitors isn’t ergonomic, but it’s what I have to work with for now, until I get more organized and am able to condense my trading processes to maybe 2 monitors or one ultra wide.

- because of my graphics card (asus RTX 3060 ti 8gb) I only have 3 display ports and 1 hdmi. The hdmi monitor is notably different in color or some setting that I cannot get to match the others. Is there a way to fix that?

My setup has been moved to the main bedroom as my gf is renovating the room my office is in, so I’m kind of crammed in the corner here. This will all move back to the office when the renovation is done.

If anyone has a wealth of advice on the subject or a definitive guide they can link me, I would really appreciate it. Thanks!!!
