More than just a distant sibling to the PG27UCDM
I can't say enough about how good this monnitor is! I own the sibling of this monitor as well a PG27UCDM. As many reviews state, this is the "stripped down" version of the 27UCDM. I use that term loosley as it only loses Dolby Vision and DP 2 .1a. I own an Astral 5090 so having the DP 2.1 was important for my daily driver. I must admit, having this as my 2nd monitor is a dream come true. Text Clarity, Speed, color...I could go on and on. While it doesn't have 2.1, you can still use it with DSC to achieve the full 240hz. I can't say it enough times, outside of the 27ucdm, there is NOT ANY OTHER MONITOR BETTER. Asus keeps leveling up the game and this is onen of their best creations.

Yes, it is an outstanding monitor.
Well, the picture is a stunner! Perfect size for my space on a desk top and a perfect picture. I am not a gamer - a disclaimer, but it seemed to have so many things right with it. You can read the technical wonders in other places, instead of my attempts at this stuff. ASUS, as I continue to read, is a reputable, dependable company. I have only had it a week, so I am not equipped to report on any problems. The only thing I will bring to your attention is that the toggle switch (is that what it is called?) was tough for me to figure out and use. Patience is a virtue, but I am learning. I, personally, prefer to have written instructions in front of me for reference and not rely on a fast-talking person with a heavy accent explaining it in 28 seconds and away we go. Overall, though, extremely satisfied. Thank you!
