How's the resolution compared to the ASD? I was actually looking for some feedback on the 40" LG 5K... If you could share some photos and let us know how your workflow works with a ultra wide compared to a regular 16:9 display would be great!
The 40" doesn't get as bright as the ASD, even on max brightness. I generally run my monitors and laptops at 50% brightness, but for me, the 40" LG wasn't bright enough unless I put it to 100%. Even then, it took some getting used-to.
Running the LG at its native resolution leads to blurry/non-crisp fonts. Not sure if that's an issue with the panel or the M1 because I'll be honest, I've lost track of what is what when it comes to these things. Drop it down in resolution and it looks brilliant, probably 90% as good as an ASD (which is also 5K).
The LG takes longer to wake from sleep over Thunderbolt than the ASD and occasionally, I'd have to unplug it to get it to come back on. That's been an issue for me with LG displays and Macs for years.
A single 40" ultra wide display was great for my workflow,
but, being unable to run it at its native resolution (I just couldn't get used to the loss of clarity), meant I ended up having more Spaces active than I'd like. I wanted to have a number of large windows on each Space, but I was limited by the lower resolution as to how many I could have had. Which kind of defeated the purpose of buying the monitor for me, so its gone back.
The speakers were ok for system sounds, but for everything else, they're very poor compared to those on the ASD. That may or may not be important to you.
TLDR; Depends what resolution you want to run the screen at. If you're not bothered about a retina-like experience at native res, go for it. At that lower resolution, everything looks amazing, but you lose screen real estate.
A few reviews of the ASD mentioned this - they're expensive compared to other options, but the things they offer that other displays don't, may be worth the extra expense. They work reliably - wake from sleep; all scaled resolutions look as good as each other; speakers are great; built-in webcam; 5k v 4k. And they do look & feel very high quality.
