Perfect choice for iMac StudioAfter much research looking for a monitor to pair with a new Mac Studio I decided on the LG 27". One of the features I really liked was the ability to not only tilt the screen but also to raise or lower it-something the Apple monitor does not offer. The monitor was simple to set up, just plug and play. Only adjustment I had to make was for brightness, easily done from keyboard. Color and contrast is beautiful. We are professional photographers working for various fashion companies so correct renditions are important to us. Highly recommend this product.

Just the best there isI have 2 of them at home for about 3 years... They replaced my humble attempts of getting one ultrawide monitor and keeping it. But the colors on this monitor are just spot on. Let it be photography, UI design, Graphics design... its... I haven't found a better and I'm buying a monitor without a budget.
It has absolutely NO features. Which is good. I don't wanna fiddle with settings and game overlays and filters and whatnot... Just works whether Im on PC or MAC...
I think I found one monitor that comes close, but the fact that its showing odd gradients it makes the other monitor unusable for my line of work.

Great Monitor but cheap cablesI just got the monitor through my upgrade with an M1 Macbook Pro and thunderbolt hub. I could not get the monitor resolution above 4K. I had an OWC thunderbolt cable for my SSD that is blazing fast. I tested monitor with that cable and everything worked fine but supplied cables were trash. So I would expected additional costs associated with this monitor purchase to get the resolution up to spec. Still need to test hub with a new cable since failed to function correctly with supplied cable.

Can the thunderbolt cable go bad? And how does one replace it?

The listing for this device on woot.com says: “The display might not turn on until you boot into macOS…pre-boot features such as Boot Picker and macOS Recovery might not be available on the display.” Is this true? Can it be the only display on a Mac mini?
