Rated 4 out of 5 by from Crystal Clear Image Pros: Crystal Clear picture, good brightness Cons: Speakers are only ok, refresh rate poor

Rated 5 out of 5 by from Perfect choice for iMac Studio After 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.

Rated 5 out of 5 by from Just the best there is I 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.
