A Huge 45-Inch 32:9 Display

The first thing you’ll notice about the LG 45GR65DC-B is its size.

This isn’t simply a slightly larger gaming monitor. Its 32:9 super-ultrawide format gives you an extremely wide desktop and gaming environment.

The 5120 × 1440 resolution effectively gives you the horizontal workspace of two QHD displays without a traditional monitor bezel separating them.

For productivity, this can be extremely useful.

You can have a browser, document, spreadsheet, communication application and other windows visible at the same time without constantly switching between screens.

For gaming, the wide field of view can make supported games feel much more immersive.

LG pairs the enormous display with a 1500R curvature, designed to bring the edges of the screen closer to your natural field of view.

200Hz Refresh Rate for Smooth Gaming

A large screen is impressive, but gaming performance matters too.

The 45GR65DC-B supports a refresh rate of up to 200Hz, along with a claimed 1ms GtG response time.

That combination is particularly attractive for fast-paced games where smooth motion and quick response are important.

Competitive FPS players, racing-game enthusiasts and anyone with a sufficiently powerful PC can take advantage of the high refresh rate.

LG also includes AMD FreeSync Premium Pro, which is designed to help synchronize the display’s refresh rate with compatible graphics hardware and reduce tearing and stuttering during gameplay.

One important consideration

A 5120 × 1440 display contains a lot of pixels.

If you want to consistently push games toward 200 frames per second at the monitor’s native resolution, you’ll need a powerful graphics card.

In other words, the monitor can provide the headroom, but your PC still has to deliver the performance.

HDR 600 and Wide Color Coverage

The 45GR65DC-B isn’t focused exclusively on refresh rate.

LG specifies VESA DisplayHDR 600 support and up to 95% DCI-P3 color coverage, which can help games, movies and other visual content look more vibrant.

The monitor uses a VA panel with a typical 3000:1 contrast ratio, which can provide deeper blacks and stronger contrast than many conventional IPS displays.

For gamers who enjoy darker environments and cinematic games, this can be an appealing combination.

One Monitor Instead of Two

One of the most interesting reasons to consider the LG 45GR65DC-B isn’t gaming at all.

It’s productivity.

Imagine having:

Left side: Browser
Center: Main application
Right side: Email, chat or monitoring tools

All on one screen.

The monitor also supports Picture-by-Picture (PBP) and Picture-in-Picture (PIP), allowing content from multiple sources to be displayed on the same monitor.

This could be useful if you regularly work with two computers, a laptop and desktop, or multiple input sources.

For people who spend hours working with spreadsheets, dashboards, editing software, browser windows or development tools, the additional horizontal space can be a major advantage.

Connectivity

LG provides a useful selection of connections, including:

• 2 × HDMI 2.1
• 1 × DisplayPort
• USB connectivity
• 4-pole headphone output
• Support for compatible high-refresh-rate connections

The monitor also includes an adjustable stand with height, tilt and swivel adjustments, making it easier to position such a large display comfortably on your desk.

Gaming Features

LG has included several gaming-oriented features beyond the basic refresh rate.

The monitor offers features such as:

• Black Stabilizer
• Dynamic Action Sync
• FPS Counter
• Crosshair
• Gamer/FPS/RTS picture modes
• Auto Input Switch
• AMD FreeSync Premium Pro

These features are designed to give gamers additional control over the image and responsiveness of the display.

Who Should Consider the LG 45GR65DC-B?

🎮 Gamers

If you want an immersive ultrawide gaming setup, the 45-inch 32:9 format is the main attraction.

The combination of 5120 × 1440 resolution, 200Hz refresh rate, 1ms GtG response time and FreeSync Premium Pro makes this a serious gaming display.

💻 Productivity Users

If you regularly work with multiple windows, the enormous horizontal workspace can potentially replace a traditional dual-monitor setup.

📈 Multitaskers

People who work with dashboards, financial charts, spreadsheets, browsers and communication tools may particularly appreciate the extra screen real estate.

🎬 Entertainment

The 1500R curved screen and 32:9 format can create a very immersive experience in compatible games and wide-format content.

Who Might Want Something Smaller?

Not everyone needs a 45-inch super-ultrawide monitor.

If your desk is small, the LG 45GR65DC-B may simply be too large.

You should also consider the graphics-card requirements. Driving modern games at 5120 × 1440 and high refresh rates requires considerably more GPU power than conventional 1080p or 1440p gaming.

And because this is a 32:9 monitor, not every game or application will make perfect use of the entire screen.
