> 3 dayI purchased a second monitor, as I moved the first to my new iMac. After several months, I am very please with the first monitor. I will post the same review below for the second monitor, as it now is attached to my MacBook Pro. This monitor is great for the price. I easily assembled the stand, plugged in the USB-C cable, and it was up and running on my 2016 MacBook Pro. The picture was fine out of the box, though way too bright for my dark studio. The colors are a little off with the auto-setting compared to the MacBook, so I will need to adjust them a bit. If anything the screen is a little too large, but I wanted the real estate to post-process photos. This was a very good purchase.

Greater than one weekUpdate 8/16/2021: one display has developed two vertical lines of dead pixels after less than a week of use. This was a Warehouse returns, so the fault lies more with Amazon than LG. I purchased a pair of these 27UN850-W displays, and they perform as you would expect from a mid-range IPS display, good color accuracy, wide viewing angle, and no dead pixels on either. For productivity work, these are perfect. 60hz refresh rate isnt going to cut it for high-end gaming although Freesync will help there. Color accuracy isnt going to be sufficient for professional design and video editing. Certified for HDR400, but know that this definitely HDR-light, if you HDR is important to you, look elsewhere. Didnt try the monitor stand, but VESA mounting worked as it should. Left, right, and top margins are about 1/4 so for multi-monitor setups you will have about 1/2 boundary between workspaces. For dual monitor work scenario for documents, GIS, code, and the like, flat panels with a wide viewing angle like these are quite good. For me, these were an excellent value from Amazon Warehouse (Used - Acceptable), where these like-new displays that are missing bonus materials cost under $300. At MSRP of $450, these are a fair price.

11-06-2025I do online tutoring for math through calculus and science through AP Chemistry and AP Physics. Between reference sheets, tables, charts, PDF books, the virtual whiteboard, desmos.com, other websites, and personal notes, I need a lot of screen real estate. Hence, I purchased two of these monitors. The base is solid metal. The monitors stay put once adjusted. The clips on the stand keep cables tidy. I also dont have to concern myself with the USB-C cables pulling on the USB-C jacks at odd angles. The picture is beautiful (turn off High Dynamic Range). Conveniently, the USB-C cable powers my MacBook Pro. The MacBook Pro drives the two external monitors, the built-in retina monitor, my peripherals listed below, all the while running video with voice over IP. With all that work, the battery level does not decrease. With a 2 USB port Hub per monitor, I have 4 USB ports for peripheral equipment. My dedicated power supply is unnecessary, so I dont have to pack it every time I leave the house (Ive forgotten it a few times). I have eliminated my USB Hub and still have a USB-C jack free. Ive cleaned up my cable spaghetti mess. My tutoring sessions are much smoother and professional. I am extremely satisfied with the purchase. Dr. Brians Education. Notes on my setup: >> MacBook Pro: 16, 2019, 2.3GHz 8-Core i9, 16GB memory, AMD Radeon Pro 5500M 4GB. >> Apple Support states the laptop will use only one supply at any given time. >> MacBook Pro power supply is rated 95W. >> Peripherals: DasKeyboard (has a 2 port USB hub, giving me a total 6 USB ports), wired mouse, TimeMachine backup drive, CD-ROM drive, WACOM tablet, an occasional iPad. >> The LG monitor USB runs at 2.0. via USB-C and runs at 3.0 via DisplayPort or the HMDI Port as I understand the manual. >> The LG monitors deliver 60W as I understand the manual.

> 3 dayI choose this monitor because it was 4k and it had a usb-c connection. Well after using it for a long time I dont recommend it. I would prefer to use a 2k monitor instead. I have two problems with it. Even dough it is an IPS panel if the image stays too long it burns the screen(I thought this wasnt an issue with this panel). Secondly, I thought that 60fps would be a cake to move but it is not. The screen has problems moving the resolution smoothly. I had the option of buying a 2k screen with 165fps and I would take that if I knew how this one works. Also, I cant use the usb-c as a display port/hdmi with my computer so it is an extra that I cant use but that is my computers fault.

10-06-2025Excellent screen resolution as used for the main screen for coding and creating in Blender with my 2019 MacBook Pro 16, but THIS IS NOT THE ULTRAFINE AS LISTED. I am still keeping the product as it is a great price for the quality, but buyer beware! The built-in speakers are not good when compared to the built-in speakers of the MacBook I am using. Also when it is first hooked up make sure to uncheck High Dynamic Range in the settings so the colors actually match your built-in retina display colors.

> 3 dayBought following a bunch of online research in which I compared 15 different monitors. Ive been very happy with this monitor in the 2 weeks Ive had it. Works great with my 2020 M1 MacBook Air using the USB-C cable thats included with the monitor. (Finding a monitor compatible with that computer was a key deciding factor for me.) The picture quality is plenty crisp and a good deal for the $480 price I paid. Ive used the ~$1200 5K LG monitor that Apple recommends, but it has ghosting issues (traces of high-brightness content take a while to decay after windows are moved around) that made me question whether the 5K was worth the price. This 4K monitor feels like a solid value in a good price/performance niche and Im glad I chose it. I mainly use it for coding and day-to-day web/email/etc. with a bit of graphics work and its done well for me in all those categories.

> 3 daySoy diseñador profesional y calibrador con la marca X rite de hace más de 10 años. Este monitor de 32 ultrafine debería costar máximo $445 con la opción de calibrador por aparte o como el modelo de 27 que no lo incluye. El tratamiento anti reflejo es semi matte pero no tiene un polarizado que ayude a mejorar los negros. El calibrador es simple y exclusivo para este tipo de modelos ips black pero con maña se puede usar en otros modelos, no es competencia para el xrite i1 studio. Cosas ilógicas el software de Lg, permite calibrar todos los perfiles menos el perfil HDR, lo cual es ilógico para un modelo de estos precios muestra la inferioridad de calibrador incluido. Destaco los 10 bits nativos de color y la cobertura del 98% del DCI P3, pero fuera de esos 2 detalles el monitor no cumple con sus supuestas mejoras a los IPS ultrafine o los PLS como mi antiguo Asus PB278Q. Se nota mucho el ips Glow lo cual pierde la experiencia de ese negro profundo, he visto más profundidad de negro en VA o PLS o AHVA, hablando en como ejemplo en escenas con mucho negro donde la debilidad se nota. Si destaco que color cuandos se muestra en imágenes normales en pantalla completa, no se nota tanto este error, pero al mínimo de una escena oscura salga o vea un contenido con barras negras vera lo inferior de la calidad de iluminación y el tratamiento del semi mate. Marcas chinas como INNOCN Mini LED de 32 (8+2) pueden ser una mejor opción que este modelo eso si teniendo en cuenta los contras que no incluye calibrador ni es 10 bits puro. Al final lo compre en una rebaja temporal, y quería pasarme a un monitor de 32, pero pienso que el precio correcto debe ser máximo $500 con el calibrador. Mi unidad posee un ligero sangrado en la parte inferior del panel en ambas esquinas y un leve sangrado superior izquierdo. Actualización 27 Feb 2023: El software de calibración suele aparecer de manera regular sin abrirlo. El ICC profile tanto v4 como v2 que se instalan en windows generan problemas de color en photoshop, tocando tener que quitarlos y confiar en la calibración por hardware que supuestamente queda grabada en el monitor digo supuesta porque el software no permite revisar donde se guarda dentro del monitor. Nunca tuve un problema de icc profile con Xrite solo con 3d max lo cual me hizo seguir usando el version 2 por compatibilidad.

> 3 dayI have tried three different 4k monitors and this one is hands down the only usable one (probably the best under $400). Its totally compatible with my M1 Macbook Pro, and give good use experience when plugged in. Picture quality is really nice and I have nothing to complain about it.

> 3 dayMy old monitor was fading and having been pleased with previous LG products decided to give this a try and glad I did. Clean functional look and gives me more desk space. Picture is fantastic and colors look natural and also many simple adjustments for different uses. Plenty of inputs for several sources, I have three computers plugged in to it. Speakers are useful if you have none but I already had a desktop sound system which is much better. The small joystick control is a pleasure to use after years of the multi button systems that never felt natural. Some complained of the stand being cheap but I find it sufficient for what it is doing. Very satified with this purchase!!!
