KVM Switch
Reddit take
AI summary of the Reddit excerpts below — not a quote
KVM switches are regarded as a 'game changer' for users who need to share peripherals between multiple computers, such as a work laptop and a gaming desktop. However, user sentiment is perfectly split due to technical frustrations; while they eliminate cable swapping, many units suffer from bandwidth limitations, lack of audio integration, and display detection issues.
Pros
- Eliminates the need to manually plug and unplug peripherals when switching between PCs
- Simple button-press toggling between devices
- High-end models can successfully support G-Sync and multi-monitor setups
Cons
- Bandwidth limitations can lead to reduced chroma (e.g., 4:2:2) or black screens
- Cheaper models often lack EDID emulation, causing the OS to lose monitor settings during switches
- High-end, multi-monitor enterprise solutions are often prohibitively expensive
- Some units do not pass through audio signals, requiring manual audio resets
Caveats
- Support for high refresh rates (like 360Hz) and G-Sync is inconsistent across different price points
- The lack of EDID emulation is a common failure point that leads to display issues
- Users report that even 'good' KVMs may not work perfectly in every setup
Best for
- Users switching between a work laptop and a home desktop daily
- Sharing a single keyboard and mouse across multiple systems
Avoid if
- You require high-bandwidth display features like 360Hz on a budget
- You are unwilling to troubleshoot potential EDID or audio routing issues

What you're looking for is called a "KVM switch", which come in various shapes and sizes and even features.
I bought his https://www.amazon.com/dp/B0CFFFHFJT?ref=cm_sw_r_cso_cp_apan_dp_DSME2K9ZWF2127N2DTVB&social_share=cm_sw_r_cso_cp_apan_dp_DSME2K9ZWF2127N2DTVB&previewDoh=1 but it doesnt appear to have an audio signal so I still have to manually reset my audio each time.
But in my case, the monitor stays turned on, while displaying nothing, but a black screen, If connected via switch.
Is the frickin' switch the problem here?
I have 2 of these and love them with my M4 and my Dell's
For using your monitor and peripherals with a desktop and laptop without switching cables, you'll want to use a KVM switch ([list of KVM switches at Amazon](https://www.amazon.com/KVM-Switches/b?ie=UTF8&node=13983771)).
Likely what you want is a KVM switch, but most will only swap one monitor, *maybe* two monitors between two pcs. There's high-end KVM switches for a lot of monitors, but they get really really expensive (they're meant as enterprise-level solutions).
KVM switch if you want to share keyboard and mouse
Yeah I have one of these. It's flawless, even gsync works fine. I switch between my work computer and gaming computer multiple times a day. I have the 3 monitor 2 computer one.
The KVM switch is the real game changer, so you don't have to have two keyboards/mice or have to plug/unplug to switch between the two. The [KVM switch](https://www.amazon.com/dp/B0CHY8L11W?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) is just a button press to toggle between "outs"/gaming PC vs laptop.
