    Welcome to a good sweet spot.

    Buying a monitor is not unlike Goldilocks trying to figure out exactly what porridge she likes. Is it too wide, too small? Too tall, too narrow? Do I need picture by picture or Picture in Picture? Do I need high ppi and usb hub built in? Do I game a lot do a game a little? Do I go with VA or OLED or IPS? These are just a few of the challenges I have had picking what ended up being this monitor. I really feel this is the sweet spot for the professional who uses the screen for both work and play. It’s a VA panel so it has great brightness, 200 MHz speed which is plenty fast for just about every

    Game changer — replaced a trio of monitors with one

    After years of trying to fit windows on one of several monitors (so they did not spread across 2 monitors), I purchased a 4k 42” monitor. That was much bigger, of course, but the windows at the top of the screen were so high they were harder to read (fine print) and caused neck strain. This one seems perfect. It fits on my desk, and there is lots of room to place windows for productivity, lab use (many windows for various instruments), and yes, gaming. I’m happy to report that my graphics card (RTX 4080) easily drives this at native resolution, at over 100 fps except for insane boss fights in

    Took me two years to find one I like!!!!

    Two yers ago when I bought my new Mac I loved it and still do!! I just wanted more screen Real estate as my brother. :-) I looked and looked for two year!! I wanted something that could keep up with the specs of my Mac when it comes to the refresh rate. My Mac runs at 120HZ the monitor can run up to 200HZ my main computer can support it up to 144HZ and it is a 2021. Even my brother who is more picky than me said 144HZ is plenty. When it comes to computers I would say he's right. I love how light is was when lifting it. It only took a few to set up! I know the price tag was definitely steep, bu

    Amazing for productivity, decent for anything else

    I found that this monitor does exactly what I wanted out of it. A way to dock both my personal and work laptops with one cable, and have it feel like I have dual monitors. This is great because my work laptop only supports one external monitor, so my dual monitor home office setup felt useless. While I only really use it for office use (I really dislike ultrawide gaming), the high refresh rate is still awesome since I'm used to 144Hz for my gaming PC and 120Hz on the native display for my personal laptop.The main reason I'm taking off a star is that I feel text may not be the most crisp I've e

    Amazing Screen! Fullfills the productivity Needs

    I got it on Cyber Monday sales, while it took a week to come, I really fell in love as soon as i unboxed it. It was super easy to setup.Pro Tip: Do not throw the box or the foam away, it has an easy to carry design which would be useful if you need to pack this beast and move to a new place.I am a sucker for USB-C connectivity charing my Macbook Pro and Macbook Air. Hence, I got the version that has the feature. I have a lot of fun using the screen! Mostly use it for productivity tasks. It is a ~45 inch screen ultra wide which means you do get less vertical size. Not a dealbreaker but be mindf

    Preliminary Review: its BIG. but beware: it will NOT work with hdmi

    first, plugged it into my widows 11 surface pro via usb c on surface dock-> hdmi on the monitor.Nothing, nothing at all, (went to sleep) can't find the off button, likely buried the the huge 1/2 page manual.then plugged it directly into the surface pro.FRCK, only 1920x1080? nothing i can do?then used their usbc to usbc, got my 5120x1440, looks nice, could be 'crisper' i don't know how to fix that.need to try it in the docking station so i don't need to do two things to dock.ok, i se lg electronics inc. -extension 1.1.2024.522 (driver) lets try that. nothing really, go to lg.com, downlaod manua

    Exceeds Expectations!

    Had to retire my Apple Thunderbolt display after 12+ years. And Chose this as my replacement. Mostly for Development work. But a bit of gaming. After all the reviews, I was concerned about the height, curve and possible dead pixels. But all concerns were non-existent. This monitor is amazing. The curve is very slight and perfect for my desk and viewing angle. The height is a tiny bit smaller than my thunderbolt display, but the vertical resolution is the same and I barely notice. For database and development work it, this is a dream. The picture is crisp and I can fit 3 nice sized windows on t
