Solid office monitor for my WFH setup (software development)
Style: Power Delivery : 90W
Review Image by Will in Colorado

Review Image by Will in Colorado
This is a review for the LG 34WQ73A-B, which appears to be a recent release (9/2022, review written 12/2022). TL;DR: This is an extremely good value for office use. I have more expensive monitors and I compare them in detail below. I have three other monitors to compare this against: an LG UltraFine 5K 27", an LG 4k 27" and an Alienware 34" with the same resolution (gaming, 144hz). I went with this monitor (34WQ73A-B) because it has an IPS panel and my other LG IPS 4K and 5K screens have very good color accuracy; my MacBook Pro renders text to both very well. I didn't need a high refresh for gaming, just 60Hz for office work as a software developer working in design systems. I have this placed next to my 5K UltraFine, which makes it easy to discern where it is a step down (pixel density). That said, it holds up well and is very comparable to my Alienware 34" at the same resolution. Font smoothing isn't as ideal as the 5K, but it looks good enough to not bother me at all. I use it for Zoom meetings, browser windows, and also code editing. I still prefer the 5K for previewing output (web development work on the front-end) but I'll use this when the details or colors don't matter as much. Regarding alternatives on the market, I had also considered stepping up to a 38" monitor for 2-2.5x the price but I couldn't justify the difference. It would have been the same pixel density, and only going to a 5K2K monitor at 38-40" would have been a real improvement, but those cost around 4-5x as much. Like I said, next to a 5K 27" monitor, it holds up and I'm not disappointed one bit, it does what it sets out to do very well. The value here is unmatched. I also compared its HDR performance next to my 5K and it held up really well (see the first photo with both displays). I had to turn the brightness to 100%, and made sure the HDR options were enabled. It was slightly less bright than my 5K, so I intentionally lowered the brightness on my 5K to match it better; the 5K was at 100% initially which was probably too bright for everyday use in the first place. The 5K at around 50% brightness matches the 34WQ73A-B at 100% brightness, so I feel like the 34WQ73A-B is a relatively dim monitor best suited to medium to low light settings. I don't work in a bright room, I keep my lights low and warm, so this is not an issue. In a bright space with lots of sunlight, it could be more of an issue, so keep that in mind. It probably wouldn't matter with good contrast, but darker images might not show up as well. If I could call out any other cons, it would probably be the backlight bleed. One photo shows approximately what you would see in a dark room (I turned off the lights) and the photo with a brighter backlight bleed is from the camera auto-exposing to a higher degree. It does not look like the brighter photo but it's still a good photo to show what the backlight variance is like. In everyday use, it's not a problem. I think it would handle a movie just fine even with dark scenes, it would just fall short of what an OLED TV panel could do. Again, if you research what a panel like this can do, I think this is going to deliver on what it should be capable of. At the current price point, it's one of the best values I've ever had in all my monitor purchasing. Each of my four monitors all fill a slightly different expectation and I'm pretty happy with my two setups for gaming (27" 4K + 34" 3440x1440 144Hz) and office (27" 5K + this LG 34" 3440x1440 60Hz). I think this is ideal as a value-oriented office monitor and you'd have to spend 5x as much to really have a noticeable upgrade in the ultrawide format. ... show more

huge upgrade from a 1080p 34 uwide variant
Style: Power Delivery : 90W
I have a vertical monitor setup with a 34" same size lg ultra wide but at 1080p vertical res instead of the 1440p seen here. I replaced one with the 1440p on the bottom and the 1080p old one on top and while similar dimensions this qhd looks much much better. I was initially against qhd because the regular 16:9 ones looked too tiny in font so i always stuck to 1080p no matter how wide it got. Fast forward to 2023 and being a godot developer on linux i saw a night and day difference in readable space using a friends monitor so i jumped the gun here to get a feel for 1440p ultra wide. For reference my usage here was to be used mainly for programming and browsing. But i could not risk the va panels no matter how tempting 49" ultra wide are because of va smearing is inescapable. Here the tried and true ips 34" lg ultra wide. No ghosting no smearing and colors even better than my old 34" 1080p ultra wide. No screen tearing on a amd minipc or setup needed. I ran a hdmi and purposely keep refresh to 60hz even if monitor is higher because ive learned that it doubles electricity usage for no reason if you don't need it for every day use. Ran some emulators from dolphin to yuzu and all ran perfect on ubuntu no screen or frame issue. No dead pixels either thankfully. Vesa mount is located higher than the previous unit so i had to adjust my clamp on the vertical pole. The power cable is a legit 3pin pc power cable. No brick so that was a relief. HOWEVER the only con i can see is the mounting points are too far down to the bottom. If you're looking for a clean 100" floating unit with cable management you need right angle cables. Find a right angle power and hdmi/dp otherwise youll hang cables down below the bottom cutoff line of the monitor. Literally not an issue just a struggle as usual for us cable management nuts but easily remedied. Another perfect banger out of lg. Their ips panels are truly perfection. Va panels however.. lol lets not go there ... show more

very good screen and feature set
Style: Power Delivery : 90W
I love the stand that comes with the monitor. very sturdy and has a good amount of vertical adjustment and a little tilt. the instruction manual is garbage.... i'm not even sure they were included in the box, i ended up just downloading it from their website, instructions are Ikea style. pictures and step #s without any explanation. good thing that to get it setup is to simply connect the 3 parts together, which was fortunately pretty self explanatory but it would have been nice if they used words (in english) to better explain the steps and not just pictures to figure out. If you are worried about the 'curve', no worries, it's very subtle and you can't tell the difference when using it. I love how this version that i bought, had the USB C hub. I was able to connect my wife's Macbook which only had 2 USB-C ports and nothing else (no power, no HDMI) and i was able to connect it directly to the monitor's USB C port and i got not only the video/audio connection but it provided enough Power to the Macbook. So instead of using both of the Macbook's USB-C ports for power and display connection, i only use a single cable directly to the monitor for everything. This is amazing for my wife as she brings the Macbook back and forth to home/work daily. Makes things easier for her. ***Do NOTE, that when i used the included Macbook USB-C cable, the Display connection did not work and i couldnt figure out why. UNTIL i used the monitor's included USB-C cable to connect and it finally worked. I think the other USB-C cable was not capable to handle both the power and the video/audio but the monitor included cable was. So use that instead. It's probably higher spec or newer version to support everything. The viewing angles are really good. That's why i went with the IPS screen instead of a lower price on sale 'gaming' VA monitors. Better for the websites/spreadsheets. ... show more

Great monitor for many
Style: Power Delivery : 90W
I use this monitor for work, and it is massive! I have it next to my Dell 27" and it looks so much better. The screen is bright and build quality is great. My favorite feature is the USB Power Transfer. I have everything connected to my monitor and then one USB-C (provided) to my laptop. It even charges my laptop. I barely have any cables now! It is a great set up! I also purchased it because it was an IPS screen which seems high quality and offers PBP which I have yet to use. Potential negatives: 1-If you want a significant curve to the screen, this curve is minimal. I sorta regret not getting a more noticeable curve. 2-It has adjustable height which is an amazing feature, but it only goes up and down very little. I wanted to lower it more, but it does not allow. ... show more

Broke under 1 year mark and poor warranty process
Style: Power Delivery : 90W
The monitor is great, love the USB C charging, etc. Mine stopped working a little over 11 months of using it. Never moved it, sat on my desk, and one day it started flickering and then the screen went out. Thankfully it was still under the 1 year warranty so I'm in the warranty process. However, my biggest issue is with the warranty process. Up to 10 business days to get a box and up to another 10 business days to get it fixed. That's a 1 month process. I use my monitor for work, which means I will not have a monitor to use for a whole month. I asked LG to send me a replacement in the meantime but they said no. The warranty process means you'll be out of a monitor from 2 weeks to a month. Update: They received the monitor on 1/29/24 and it's 3/5/24 and I still have not received a fixed monitor or refund. I'm currently awaiting approval from the "higher ups" for a resolution. This is absurd. ... show more

Big, Bright, and wonderful monitor
Style: Power Delivery : 90W
"I recently upgraded my workspace with the LG UltraWide QHD 34-Inch Curved Computer Monitor (34WQ73A-B), and I must say, it's been an absolute game-changer. The expansive 34-inch curved display has not only enhanced my productivity but also transformed my entertainment experience. With its QHD resolution, the clarity and detail in images are nothing short of stunning, making every task from editing documents to watching movies a real pleasure. The monitor's ultra-wide aspect ratio is perfect for multitasking, allowing me to seamlessly work on multiple windows side by side without any compromise on space. This has significantly reduced my need to switch back and forth between applications, saving me both time and effort. The color accuracy and brightness levels are impressive, providing vibrant and consistent colors across the entire screen. Ergonomically, LG has hit the nail on the head with this model. The adjustable stand and the curve of the monitor make for a comfortable viewing experience, even during long hours of use. This has been a boon for my posture and overall comfort at the desk. The connectivity options with USB-C, HDMI, and DisplayPort are ample for my needs, making it easy to connect various devices without a hitch. While the monitor is nearly perfect, there's always room for improvement. The menu navigation could be more intuitive, and an increase in refresh rate would be welcome for those heavy into gaming. Nevertheless, these are minor quibbles in what is otherwise an outstanding product. In conclusion, the LG UltraWide QHD 34-Inch Curved Computer Monitor (34WQ73A-B) is a fantastic addition to any workspace or home office. It offers superb visual quality, a comfortable viewing experience, and a sleek design that would complement any desk setup. I wholeheartedly recommend it to anyone looking to enhance their computing experience. Five stars well deserved!" ... show more

Mac Users Beware: LG Knows It Doesn’t Work — But Doesn’t Tell You
Style: Power Delivery : 90W
Review Image by Cajun Guy
The display is excellent. The USB-C connection works smoothly. It’s a beautifully designed monitor with great visual performance. But if you’re a Mac user — especially on macOS 15 (Sequoia) — there’s something LG chooses not to tell you here.Key features like OnScreen Control, KVM switching, and Dual Controller rely on LG’s proprietary software. But that software doesn’t currently work with macOS 15. Not partially — completely nonfunctional. LG knows this. They say so — loudly — on their own support site in giant bold font (see photo). And yet, here on the Amazon product page? Nothing. No disclaimer. No warning. Not even fine print. Mac users will read the specs and descriptions and reasonably assume these features work as advertised. By the time I found out, I had already assembled the monitor, routed the cables, and built my hybrid setup around features that simply don’t exist on macOS right now. LG’s support page tries to frame this as Apple’s fault — suggesting they didn’t have enough time to update their software. But what speaks louder: the pace of Apple’s OS updates, or the fact that LG kept selling this to Mac users without a single word of transparency about these broken, advertised features? The way LG fully blames Apple brought this to mind: Which company showed less respect for its users — the one that moved fast, or the one that stayed silent while taking your money? Well… the answer’s pretty clear. ... show more
