Monitors

Good morning, I am in the market for replacing my fairly generic Philips 60hz 1440p IPS office monitor that I have used since 2017, it has issues with image retention and I want to upgrade to a higher refresh rate and move to a dual monitor setup.

I am currently decided on getting one or two monitors of either of these models.

But I have a few questions...

First a bit of an unusual requirenment, I need a monitor with an audio out, I seem to have borked my onboard audio on my computer, I get nothing when connecting my amp directly to my motherboard, it worked fine for a day or two after I built the system, but when I wanted to upgrade my cable, it just never worked, for a few days I used the front headphone jack, but the cable got caught in my chair and pulled the computer case over when it was running, it also yanked one ring out of thw 3.5mm jack.

So I have no on board audio I can use, this means that I send my audio through the display port cable and out through the audio out of the monitor to my amp, this works great, but poses some questions that I will get to.

At the moment, I am looking at getting one DE and one D, connecting them with a DP cable so I can easily switch between my desktop and my work laptop.

This means that I'll mostly be relying on MST from my desktop to my secondary monitor.

I will only game on my primary monitor, the other will either be off or show my desktop/chat, how would that affect gaming?
