The Best 40 Inch Monitor For 2025

The INNOCN 40C1U is a powerhouse display, offering a 5120 x 2160p 5K resolution across an expansive 40-inch ultrawide screen. With 135% sRGB and 106% DCI-P3 color coverage, plus a Delta-E < 2 factory calibration, it delivers precise color accuracy right out of the box. Designers, video editors, and creative professionals will find this monitor particularly appealing, combining sharp detail and rich, lifelike colors.

Beyond visuals, the monitor is designed to enhance productivity. The 21:9 aspect ratio provides extra screen real estate for multitasking, while the 100Hz refresh rate ensures smooth performance whether you’re working or gaming. Built-in speakers add everyday convenience, and the slim, three-sided bezel design gives it a modern edge. The stand is adjustable for height, swivel, and tilt, and VESA mounting is also supported for a customized setup.

Connectivity is another highlight, with HDMI 2.1, DisplayPort 1.4, and USB-C (65W power delivery) ports covering everything from laptops to gaming consoles. The only minor drawback is that the power cable is a bit short. Still, with its balance of performance, style, and function, the INNOCN 40C1U is a strong contender for anyone seeking a premium ultrawide experience.

The Deco Gear 40 Curved Monitor offers impressive clarity, color accuracy, and immersive design. Its expansive 40-inch curved display with 5K resolution creates an engaging visual experience, making it just as suitable for creative professionals as it is for gamers. HDR10 support further enhances contrast, ensuring bright highlights and deep blacks come through with striking realism.

The VIEW401 covers 95% of NTSC, 96% of DCI-P3, and 100% of sRGB, so it reproduces colours accurately and brightly. This makes it a great choice for photographers, videographers, and graphic designers. The 21:9 aspect ratio allows users greater space to do more than one thing at once, and the PIP and PBP features make it easier to work with more than one input at a time.

When it comes to responsiveness, the 6ms response time with overdrive keeps motion smooth and blur-free, while Adaptive Sync technology helps eliminate screen tearing during fast-paced gaming or video playback. Although navigating the on-screen menu feels a little awkward at first, it’s a minor tradeoff considering the overall performance and features.

The Dell UltraSharp U4025QW is more than simply a large display; it's a tool for productivity in creative, professional, and entertainment endeavours. Its 39.7-inch screen offers a large surface, allowing users to comfortably multitask or work with comprehensive content side by side. With 600 nits of brightness, the display retains clarity and vividness even in brightly lit environments, making it excellent for offices with ample natural light.

Performance-wise, this monitor holds its own with a 5 ms response time, delivering smooth visuals during fast-moving content like action films, sports, or casual gaming. USB Type-C connectivity enhances productivity by simplifying setup—power, data, and video all flow through a single cable, reducing clutter and making it easy to connect laptops and other devices.

One area where it doesn’t shine as brightly is the built-in speakers, which are serviceable for basic use but may fall short for those who want a richer audio experience. But you can pair this monitor with external speakers or headphones for better sound quality, so you don't need to worry about that. 

MSI’s MAG401QR is a monitor that knows its audience: competitive gamers and immersive play enthusiasts. Its 40-inch ultrawide format paired with 3440x1440 resolution ensures plenty of screen space, while also pulling you deeper into the game with panoramic visuals. The 21:9 aspect ratio enhances peripheral vision, making it especially effective in racing, FPS, and strategy titles where awareness of the wider environment matters.

The MAG401QR has a refresh rate of 155Hz and a reaction time of 1ms, which keeps motion sharp and input lag to a minimum. This is great for fast-paced games where every second counts. The IPS display keeps colours stable and stops images from getting distorted, so they always seem right, no matter what angle you look at them from. MSI Mystic Light lets the lights on your monitor sync with other compatible hardware, giving your gaming setup a coordinated, customisable glow.

At 40 inches, this monitor is naturally a bit heavy compared to smaller models. While this makes moving or adjusting it less convenient, it’s a minor consideration given the visual and performance benefits. Ultimately, the MAG401QR provides the kind of speed, scale, and style that modern gamers crave.

The LG 40WP95C-W is a professional-grade display that bridges productivity and creativity. Its 40-inch curved WUHD (5120 x 2160) panel provides an expansive panoramic view, making multitasking seamless and design projects more detailed. With Nano IPS technology, the screen produces sharp clarity and consistent colors across wide angles, which is ideal for video editors, content creators, and designers who require accuracy.

Color performance is impressive, offering 98% DCI-P3 coverage alongside HDR10 support, which brings natural textures, shadows, and highlights to life. Whether you’re editing footage or diving into immersive entertainment, visuals feel vibrant yet true-to-life. The 3-sided, virtually borderless display adds to the aesthetic appeal, while tilt and height adjustments ensure ergonomic comfort during long work sessions.

Connectivity is equally robust. Thunderbolt 4 with 96W power delivery simplifies setups by allowing you to charge laptops while transmitting data and video through a single cable. This makes the monitor as practical as it is powerful. The only minor downside is that mounting can be a little tricky, requiring extra care during setup. Still, once in place, the LG 40WP95C-W offers one of the most complete ultrawide experiences available.

Samsung designed the Odyssey G7 40” with one goal: to deliver a gaming experience that feels larger than life. The 21:9 WUHD resolution pairs beautifully with the aggressive 1000R curvature, making games feel as though they surround you. VESA DisplayHDR™ 600 further enhances realism by bringing deep contrast and brighter highlights, so even shadow-heavy scenes in RPGs or shooters retain crisp clarity.

Performance is another highlight. With its 180Hz refresh rate and near-instant 1ms response time, motion is fluid, lag is almost nonexistent, and every frame feels responsive. AMD FreeSync™ Premium Pro keeps things stutter- and tear-free, syncing perfectly with your GPU for competitive smoothness.

Samsung didn’t forget about versatility either. Picture-by-Picture and Picture-in-Picture functions allow multitasking—watching streams or managing chats while gaming. CoreSync technology with 16.7 million colors projects ambient lighting that syncs with on-screen action, extending immersion beyond the panel itself. Meanwhile, the ergonomic stand ensures you can adjust tilt and height for long-haul comfort. However, this is a premium monitor for gamers who demand the very best, and while costly, its feature set justifies the investment for those seeking peak immersion.

The Monoprice 40" Monitor takes multitasking and creativity to a new level with its immersive ultrawide format. At 3440 x 1440 resolution, it provides ample screen space to manage multiple windows side by side, boosting productivity without needing a second monitor. The IPS panel ensures colors remain consistent from every angle, making it equally suited for design work, editing, and general content consumption.

HDR600 compatibility improves the quality of the visuals by adding amazing brightness and contrast to movies, games, and intricate projects. This monitor has a wide colour gamut (NTSC 105%, DCI-P3 95%, sRGB 99%, and Adobe RGB 89%) and professional-grade accuracy that designers will love. A refresh rate of 144Hz makes performance even better by decreasing motion blur and making sure that transitions are smooth, whether you're working on fast-moving pictures or playing a fast-paced game.

At 40 inches, the monitor naturally commands a large footprint. For smaller desks, it may feel overwhelming at first, but for those with the space, it’s a centerpiece that offers unmatched versatility. Overall, the Monoprice 40" Monitor is a powerful tool for productivity and entertainment alike.
