ASUS MAG ALOGIC Aspekt 32" 4K HDR Multi-Touch Docking Review
The LG 27BA45U-B tries to be everything for your desk with 4K, USB-C, and a webcam. We checked if this jack-of-all-trades is a master of none.
The 30-Second Version
The LG 27BA45U-B is a 27-inch 4K office monitor with a useful set of features like USB-C, a webcam, and a fully adjustable stand. Its performance is average with a 60Hz refresh rate, but it excels as a tidy, versatile desk centerpiece for general use. Look for it at a mid-range price, not at the extreme highs some vendors list.
Overview
If you're looking for a 27-inch 4K monitor that's basically a Swiss Army knife for your desk, the LG 27BA45U-B deserves a look. It's a 27-inch IPS panel with a 3840 x 2160 resolution, 300 nits of brightness, and HDR10 support. It's not a gaming beast or a color-grading powerhouse, but it's built to handle a bit of everything—office work, casual content creation, and media consumption—all while keeping your desk tidy with a USB-C port. Our data shows it scores highest for office use, which makes sense given its feature set and ergonomic stand.
Performance
Let's be clear: this isn't a performance monitor. With a 60Hz refresh rate and a 5ms gray-to-gray response time, it lands in the 38th percentile for performance in our database. That means it's fine for everyday tasks, web browsing, and even some light gaming if you're not competitive, but you'll notice motion blur in fast-paced action. The 4K resolution is the real star here, giving you tons of screen real estate for spreadsheets and documents. The 300-nit brightness and HDR10 support are okay for a dim room, but don't expect it to fight off glare in a sunny home office.
Pros & Cons
Pros
- Excellent ergonomics with full height, tilt, and swivel adjustment 100th
- Clean connectivity featuring a USB-C port for single-cable setups 96th

- Panel is listed as IPS in some places and VA in others, causing confusion

Value & Pricing
Here's the wild part: we've seen this monitor listed for anywhere from $75 to a frankly ridiculous $7,000. Ignore the extremes. At a reasonable street price (think $300-$500), it's a solid value for a fully-featured 4K office monitor. You're paying for the ergonomic stand, USB-C, and built-in webcam more than pure panel performance. If you find it on the lower end of that range, it's a decent deal. If a seller is asking anywhere near four figures, laugh and walk away—there are much better monitors for that money.
Price History
vs Competition
Compared directly to other office-focused 4K monitors, it holds its own. The Dell UltraSharp U2723QE, for example, typically has better color accuracy and a more premium build, but often costs more. The LG 27BA45U-B fights back with its included webcam and often more aggressive pricing. Against a gaming monitor like the ASUS ROG Swift series, there's no contest—those will blow it away in refresh rate and response time, but you'll lose the USB-C and ergonomic flexibility. For pure office work, this LG is a more practical package than a stripped-down budget 4K screen from brands like Acer or AOC, which often skip the good stand and USB-C.

Common Questions
Q: Is the LG 27BA45U-B good for gaming?
Not really. With a 60Hz refresh rate and 5ms response time, it's fine for casual games, but competitive gamers will want a monitor with at least 120Hz and a faster panel.
Q: Does this monitor have USB-C power delivery?
It has a USB-C port, which is great for video and data, but the specs don't confirm power delivery. You'll likely still need a separate charger for your laptop.
Q: How does the LG 27BA45U-B compare to a Dell UltraSharp?
Dell UltraSharps often have better color accuracy and build quality, but this LG includes a webcam and can be cheaper. It's a trade-off between premium color and convenience features.
Q: Can you mount the LG 27BA45U-B on a monitor arm?
Yes, it has a standard 100x100 VESA mount, so you can easily take it off the included stand and put it on an arm if you prefer.
Who Should Skip This
Skip this monitor if you're a serious gamer, a video editor needing color accuracy, or someone working in a very bright room. The 60Hz refresh and average color performance won't cut it for those uses. Gamers should look at 120Hz+ options from ASUS or MSI, creatives should consider Dell UltraSharps or BenQ models, and anyone needing brightness should find a panel with 400 nits or more.
Verdict
Should you buy the LG 27BA45U-B? It depends on your priorities. If you need a single monitor for a hybrid work setup—video calls, document work, some Netflix—and you value a clean desk with USB-C connectivity and a fully adjustable stand, this is a sensible choice. But if your main focus is gaming, color-critical creative work, or you need a super-bright screen, you should look elsewhere. Think of it as a competent all-rounder, not a specialist.
