Is anyone using Parsec with BetterDisplay for edits?

I'm putting this question out there to see if anyone else is doing something similar. I've been running Parsec over a modest 1Gbps home network, paired with BetterDisplay to ensure proper 4K+ 60fps signals are sent to my iMacs—while editing 6K video on very modest hardware.

For those unfamiliar, Parsec is low-latency remote desktop software. With BetterDisplay, I can match the resolution to the native Retina display of my iMac, allowing me to work from two different locations in my home without needing multiple high-end machines—or a 10Gbps network. The end result? It feels like I'm using an Apple M2 Mac Mini directly on a 2019 4K iMac. Honestly, I can barely tell the difference. I’d estimate the latency is under 25ms with this setup.

Now I’m curious—has anyone tried this off-site? I imagine cross-continent setups would suffer from latency, but within the same continent, it seems like remote editing could be entirely feasible. It sure beats lugging around terabytes of footage.

For me, this setup has breathed new life into an older machine. I’m even considering picking up another iMac—maybe a 5K model from 2017 or later. With H.265 decoding not being too demanding and the M2 or M4 Mac Mini handling encoding with ease, it seems like a highly effective and budget-friendly workflow.

I never tried editing with Parsec, but it's a good idea!  How does it handle color management?  Or is that done by Better Display?

I’m not 100% focused on color accuracy here—I rely on scopes for that—since calibrating two machines in different environments is never going to yield perfect results. My main reason for using BetterDisplay is to match the exact 4096x2304 resolution of my 2019 4K iMac. Retina displays don’t play nicely with standard external monitors, like the one I currently have connected to the M2 Mac Mini.

I’ve heard some users connect “dummy” displays to the encoding machine to force the proper resolution, but this setup with Parsec achieves the same effect. If I send a standard 4K signal to the iMac, it doesn’t look as clean—the image is upscaled and noticeably less sharp. With this setup, I just launch Parsec and connect to the M2 Mac Mini. What I see on the iMac looks almost indistinguishable from running natively on the 2019 i3 iMac with 8GB of RAM—except, of course, I get the performance of the M2 Mac Mini.

In fact, I often forget I’m even using Parsec. I’ve accidentally shut down the Mac Mini thinking I was turning off the iMac! And the biggest surprise? I’m getting Thunderbolt 4-level performance on my media drives—despite using only a 1Gbps Ethernet connection. As long as latency stays below a certain threshold, the experience is virtually seamless.

The iMac just becomes a glorified thin client- exactly what I want.

If macOS ever supported multiple simultaneous users, I’d happily run just one Mac Mini and use 3–4 iMacs around the house as thin clients for the whole family. I’m confident the performance would be more than sufficient—as long as no one is editing video at the same time!

Unfortunately, that’s not the case. But there’s nothing stopping me from setting up several iMacs as thin clients, each connected to its own Mac Mini. By placing the Mac Minis next to each other and linking them via Thunderbolt, I could enable ultra-fast access to shared resources—effectively building a small, high-speed local computing cluster with shared storage and plenty of power.

I often use Splashtop Remote Desktop when editing remote and its always been very reliable. My main use-case is making an edit on a windows machine hooked up to a bunch of media servers in one city and I'm in another city on a MacBook. It handles the keyboard mapping and display scaling extremely well.

It also has support for multiple monitors, so I can plug the MacBook into 2 external displays and have all 3 screens mirror the 3 Windows screens. Or assign them to spaces if I'm using the MacBook without the externals. 

Another advantage, in my case, is it has the option to blank the screens on the remote computer, and runs through a secure network, so feels very safe if you need that.

I'm curious about Parsec, but it seems to be a similar price for similar feature set. Since Splashtop is doing the job just fine, I'm debating if its worth the time to research and switch over.

For colour depth, both say they're 4:4:4 so I don't think that's much of an issue.

I've been using the free version only. However, I did pay for BetterDisplay ($20)- for me, it's worth it and they did a hell of job that needs to be rewarded.

I'll definitely have a look at this too. Thanks for that.

You might be talking me into reinstalling Parsec and trying this out, but for different reasons.  Usually I edit on my Macbook (The lower-end M2 Max) and it's totally fine, but when I'm at home, I prefer to edit off my basement NAS instead of from external drives and I use a postgres database on a server next to it.  But if I don't plug into the network (which means sitting at my desk where the dock with 10ge is), editing video is not great (and editing photos in Lightroom ain't great either).

But I have a windows gaming PC also set up near the desk which has a pretty decent setup with a nice GPU.  I suppose I could just parsec to that while on the couch or in bed and do my editing, with the main catch being that I need to use Windows shortcut keys.  That or I wait until there's a decent deal on an M4 Mini with 10ge (there have been some solid deals, but they're always for the base model with only 1ge)
