Finding the right monitor for gaming and multitasking isn’t easy, especially with all the choices out there. The LG Ultragear 45GR75DC really grabs attention with its massive 45-inch curved screen and 32:9 aspect ratio—it’s basically like having two monitors without that annoying bezel gap in the middle.
- 45" QHD (5120 x 1440) Curved Display - Make room on your desktop for the massive 45” curved UltraGear QHD monitor with a 32:9 aspect ratio. Play, stream and create on a high refresh rate display, in vivid color, on one screen at the same time.
- VESA DisplayHDR 600 with up to DCI-P3 95% - This UltraGear display supports up to 95% of the DCI-P3 color gamut, expressing high-fidelity color paired with VESA DisplayHDR 600 delivering dynamic contrast and brightness on the QHD display..
- Picture in Picture / Picture by Picture - OnScreen Control supports both Picture-in-Picture (PiP) and Picture-by-Picture (PbP) allowing you to configure your monitor to show content from two separate input sources. Play, watch, stream or work from multiple input sources at the same time, on one screen.
People generally praise the sharp picture, accurate colors, and fast refresh rate, saying it works well for both games and getting work done. Still, there are a few complaints—ghosting can pop up in some fast-paced games, and not every title really takes advantage of the ultrawide format. The adjustability and KVM switch are nice touches for folks with more complicated setups.
Overview of the LG 45GR75DC-B Ultragear Curved Gaming Monitor
If you want one screen instead of juggling two, a 45-inch ultrawide display like this is hard to ignore. The curved panel is built for both gaming and productivity, with a high refresh rate and solid color coverage. Its dual QHD resolution gives you a ton of room for multitasking or just diving into a game.
Colors look vibrant and sharp, though some folks have noticed VA ghosting during fast motion and a few hiccups with older games or certain apps. The 3-way adjustable stand and plenty of ports—including USB-C—make it pretty flexible.
It’s a big piece of hardware, so you’ll need the desk space, but if you’re tired of bezels and cable mess, this monitor’s a tempting alternative.
Immersive 45-Inch Curved QHD Display
Sitting in front of this 45-inch curved screen is kind of wild—the 32:9 aspect ratio and all that screen real estate make everything feel more immersive, whether you’re gaming or just multitasking. The curve definitely helps pull you in, especially for fast games or when you’ve got a bunch of windows open.
Some people love the extra space for productivity, but if your desk is on the small side, this thing might be a tight fit. The matte finish does a decent job with glare, but honestly, a screen this wide means you’ll be turning your head a lot. If you want that wraparound feel and more room to work or play, it’s a standout—just maybe not for every setup.
Seamless Gaming with 200Hz Refresh Rate and 1ms Response Time
Fast-paced games look and feel smoother here. The high refresh rate and quick response time are supposed to keep motion blur and input lag to a minimum, so things feel crisp when the action ramps up.
Most users say gaming is fluid, with less tearing or stutter, assuming you’ve got the hardware to back it up. But, only the beefiest graphics cards can really push some games to 200Hz at this resolution.
Pros:
- Noticeably clearer motion in fast games
- Snappy responsiveness, helpful for competitive players
Cons:
- You’ll need a strong PC to max out the refresh rate
- Casual games or slower content may not look much different
Vivid Color and Dynamic HDR Performance
Colors pop on this big curved screen. HDR content shows off good contrast—bright highlights, deep blacks—so games and movies look more dynamic.
The wide color gamut makes visuals look more true-to-life than a standard monitor, though ghosting and inverse ghosting can crop up at certain response settings, especially in fast scenes.
Pros:
- Bold, punchy colors
- HDR brings out solid brightness and contrast
Cons:
- Ghosting can happen with quick movements
Versatile Connectivity and USB Type-C Power Delivery
Plugging in devices is pretty straightforward here. The USB Type-C port with Power Delivery is a bonus if you want to charge your laptop or power gadgets while you work or play.
A lot of people like how it cuts down on cables and makes swapping devices easier. That said, the USB-C power output might not be enough for some high-powered laptops—double-check your needs before relying on it. Still, the connectivity options are a strong point, especially if you’re running multiple setups.
Advanced Multitasking with Picture-in-Picture and Picture-by-Picture
If you’re juggling a couple of devices, PiP and PbP are super handy. You can see content from two sources at the same time—maybe work on one side, stream on the other, or keep an eye on data while gaming.
Switching modes is pretty easy with OnScreen Control, though it might take a minute to get the hang of it. The 32:9 aspect ratio really lets you use these multitasking features to the fullest, with plenty of space for both windows.
Pros:
- Use two devices at once
- Makes split workflows or gaming/streaming combos easier
Cons:
- OnScreen Control isn’t totally intuitive at first
- Not everyone will need this much multitasking power
Adaptive Sync for Smooth Gameplay
Screen tearing and stutter are a pain, especially at high resolutions. The Ultragear’s AMD FreeSync Premium Pro helps smooth things out in fast games.
With a high refresh rate and a compatible GPU, most users see less tearing and lag. There are still occasional mentions of ghosting at certain settings, but for the most part, the adaptive sync keeps things looking smooth.
This monitor really shines with newer graphics cards that support variable refresh rates. If you’re picky about visual artifacts, you might notice some minor issues, but it’s a big step up for most gaming setups.
Customizable Ergonomics and Gamer-Oriented Design
The three-way adjustable stand is a big plus. You can tweak height, tilt, and swivel to get comfortable, whether you’re gaming or working all day. A lot of users say this helps cut down on neck and back strain.
The nearly borderless screen and LED Hexagon backlighting give it a modern, gamer-friendly look. Just keep in mind, the stand itself is pretty big, so plan accordingly if desk space is tight.
Key Gamer-Focused Features:
- Ergonomic stand for comfort
- Minimal bezels for better immersion
- Backlighting adds a cool touch
The stand feels sturdy, but it does hog some real estate. Overall, the design hits the right notes for gamers and multitaskers without going overboard.
Audio Experience with DTS Headphone
DTS Headphone is a highlight here if you’re into immersive audio. It’s designed to make game sounds more directional, so you can pick up on footsteps or other cues a bit more easily.
People say it works best with good headphones—don’t expect miracles with budget gear, and it’s mostly useful for gaming rather than music or movies.
Pros:
- Better positional audio in games
- Works with any wired headphones (4-pole jack)
Cons:
- Only as good as your headphones
- Not much impact outside of gaming
It’s not a replacement for a full surround setup, but it does give a little extra edge for competitive or immersive games.
Pros and Cons
Pros
The 45-inch curved screen creates an immersive viewing environment, which a lot of people find great for both gaming and getting work done. The 32:9 aspect ratio means more multitasking space, minus the gap you’d get with two monitors.

Cons
The ultrawide format isn’t supported by every app or game, leading to black bars or weird stretching sometimes. Ghosting is a recurring complaint, especially during fast movement or with certain response settings.
It’s a massive monitor, so tight spaces might not work. Setup isn’t tricky, but you’ll want to be careful with the big panel.
Some folks think the price is steep unless you snag a discount or open-box deal. Compatibility with older devices or cables can also be a minor hassle.
Main Drawbacks:

- Pricey if not on sale

That said, VA panel ghosting and compatibility issues with some games or apps do come up. The size can be overwhelming in smaller spaces. Reviews are generally positive, especially when folks get a deal, but some mention inverse ghosting at higher response times.
