    -EDIT- About 6 months in, and this is still a fabulous monitor, I couldn't be happier. It does everything well that I wanted it to do, and then some. Highly recommended.

    I like to read ebooks on my PC, so there are a few things that are important to me. 1) Picture quality. This monitor has a GREAT picture. 2) The monitor actually works. I had to send an AOC monitor back for refund prior to this one due to a permanent red line down the middle of the screen. So far so good with this one. 3) A "reader mode" to reduce blue light. Check. 4) High resolution. Check. 5) IPS display. Check. 6) I read comics too, so I need the monitor to rotate to "portrait" configuration. Check. 6) Height adjustable so I can put it on my monitor stand, and stand up when I want to. Check.

    All in all I'm very happy so far, assuming it doesn't fail like the AOC I just sent back. One odd design decision, in my opinion, is the base. It's a really wide arc of plastic, almost as wide as the monitor itself. It's not a problem, so I'm not taking a star off, but I would have preferred a more utilitarian, traditional base. The base actually sticks off the edge of my monitor stand a little.

    One added bonus is that you can turn off the stupid power LED on this one! Hurray! Man I got tired of my old monitor blinking at me all night.

    The OSD is nice, and the multiple "split screen" modes are something I've wanted for a long time.

    Oddly, the audio actually sounds better than the integrated sound from my motherboard. It's more clear, louder, etc.

    Overall, A+ so far. I really can't say enough about the picture quality. Fan-tastic.

    We have 2 LG large screen TV's (1 LED and 1 OLED) and a LG bluray player. But this is our 1st LG monitor. We are not disappointed! Beautiful large screen monitor.

    Due to the pandemic we've had to work from home and what happens the 2nd week of WFH, our old monitor completely dies... Had to make an emergency order for a new monitor to keep working. The original order, for the model that was $50 less, got lost in shipping, totally understand and completely grateful to those who went to work during the height of the pandemic in the NE. Amazon provided a refund and we ordered this model instead since the other model was sold out... This replacement was $50 more but now that we've had it for a few months it is well worth it!!! Being able to lift it up and down depending on the height of the person using the computer was 100% worth the increase in price.

    The display is so clear and crisp. We have not used it to play games yet but playing a 4k movie on this monitor is amazing! The details are so sharp and crisp. The colors are so vibrant that we now feel like we are seeing in SD in RL LOL

    Being able to switch between 3 devices (2 work laptops and a personal PC tower) is so useful and helpful. We are able to keep the work laptops connected at all time without having to constantly plug/unplug and potentially damaging ports and cables.

    Also, we do not have eye fatigue as we used to have with other monitors... That is an added perk!

    Definitely worth the investment.

    I'll cut to the chase with this review. If you're a gamer, can run 4k at 60FPS, don't want to spend a fortune, this is the panel for you. You're not finding better for the price, unless there's a sale. I got this panel for $280 down from $400. Read this review.

    Here's the quick specs: 4K, 60hz, HDR, Freesync, 5ms GtG, IPS, 98% sRGB color range.

    You may be wondering how the UL550 compares to the 500, 600 and 650. They all have the same panel, except brightness. The 500 and 550 both are 300 nits in brightness, while the 600 and 650 can reach 400 nits. Truth be told, 300 is plenty bright enough, is above the average, and actually makes more sense. All 4 panels only hit 300 nits in HDR. The HDR400 on the Ul650 doesn't truly hit 400 nits, go look at reviews.

    Now for this monitor I tested it on an Xbox One X with HDR10, 4k and Freesync enabled. I played Modern Warfare, Blackout, various Rpgs, etc. The response rate and input lag is exceptionally low for an IPS. You will not feel the difference if you're coming from a TN panel, but you will notice how much nicer the image on this is. It's very impressive for IPS. The color range is almost 100%, so yeah, enough said on that.

    HDR is nice, it shows. For those that say you need 1000 nits to hit true HDR, that's true if you're looking at a TV which is supposed to be viewed from 6ft+ away. 1000 nits on a monitor right in front of you would screw your eyes up. I tested HDR on/off on various titles and the conclusion is, keep it on!

    If gaming on an FPS avoid the FPS preset. It sets the response rate to "faster" which is uneccesaey and kills some image quality. Instead use the custom feature, make sure the game response rate is on "fast", enable freesync, then enable it on your Xbox/PC. Leave the Backlight brightness as 100, contrast at 60-70, and sharpness at 40. Don't use super resolution, you don't need it if you're seeing 4k.

    Have a nice day. Enjoy the monitor, it's fantastic.

    I bought this after reading a stellar review from a photographer, and it does not disappoint. The clarity and accuracy of the colors is absolutely amazing. Granted I'm only starting out and have not used many different monitors specifically for photo editing and design work, but for me it more than fits the bill.
    The design is nice, though the curved base of the stand is a little awkward, but still sturdy. Love that its adjustable.

    The only downside is that it only runs in 30hz or 60hz and I'm having issues with gaming on it. I didn't buy it for that, so it's not a huge deal as I run dual monitors and the other monitor *is* for gaming, but just thought i'd mention it in case anyone was thinking of using it for gaming. (It also may just be an issue of getting the settings adjusted better)

    5.0 out of 5 stars Excellent monitor for my purposes
    Reviewed in Canada on April 10, 2024
    Review for adjustable height, no USB-C 27". I am using this as a primary monitor attached to my 2022 MacBook Air, M2. After trying the least expensive 4K 27" monitor listed by Amazon with disastrous result I found this LG on warehouse deals. I do not game, using it for home office purposes. I find the colour, brightness and all other picture settings to be excellent. I particularly like the adjustable height which is very smooth and a one finger process thanks to an ingenious gas shock system. My resolution setting is 3008x1692, 4K is too much for everyday but the 4K setting does great for 4K movies. I needed to tweak the desktop icon sizes and set a preset for zoom for often used web pages in Safari settings. I have not tried the LG software because I use Microsoft RDP between the MacBook and my secondary Windows PC. By doing that I did not need to adjust any display settings for the windows PC as it just follows the MacBook settings. Very happy with my purchase decision and that I got a substantial savings by finding the warehouse deal.

    Great picture quality and the OSD settings are great to adjust to what you are viewing; I used the HDMI ports with a video card from Amazon as well to have a 4 Display Panel.
    The price is right for this monitor LG makes great monitors.

    Lo uso principalmente para trabajo, programas de edición de imagen y video y se ve realmente bien. Los colores se ven intensos y brillantes. Ocasionalmente le conecto un Apple TV 4K de primera generación (2017) y se ve excelente para películas y videos. No lo he utilizado para juegos, pero supongo que la imagen debe ser bastante buena, aunque que la frecuencia es de máximo 60Hz.

    5.0 out of 5 stars El mejor monitor que he tenido hasta la fecha.
    Reviewed in Mexico on October 13, 2019
    Es perfecto, llevo 4 meses utilizándolo y estoy sorprendido.
    Solo lo calibre un poco cuando llegó y desde ese entonces todo se ve perfectamente.
    Los colores en mi trabajo es importante que no varíen y con este monitor no he tenido problemas.
    También lo he utilizado para jugar con freesync y modo extended y usando una GTX1080ti y hasta ahorita todo bien y se juega fluido .

    En general si buscas un monitor 4k te recomiendo este completamente, lo único malo diría yo es que va a 60hz pero pues a esta resolución es muy raro encontrar algo que vaya más de 60hz y que sea panel IPS.
