General Information:

The 240Hz OLED Smart gaming monitor that's ahead of the (800R) curve

The huge 45" WQHD OLED with a steep 800R curve and up to 1300 nits (APL 1.5%) peak brightness pulls you deep into the action, while a 240Hz refresh rate and 0.03ms response time keep gameplay insanely fast and smooth.

Up to 240Hz & 0.03ms - Outrageous OLED Gaming Speed

Game at the speed of OLED with an ultra-fast 240Hz and near instantaneous 0.03ms (GtG) response time. The faster speed lets you respond quickly to opponents and enjoy smoother scenes with less lag or ghosting.

Ultimate Frame Sync: FreeSync™ Premium Pro & G-SYNC® Compatible

Say goodbye to screen tearing and stutter. With AMD FreeSync™ Premium Pro and NVIDIA® G-SYNC® compatibility, this OLED monitor delivers ultra-smooth, tear-free visuals, giving you perfect frame sync across PC and next-gen console gaming.

Size Matters in OLED Gaming

The 21:9 45" UltraGear OLED delivers the ultimate ultra-wide screen space for gaming, offering more screen area than a 49" 32:9 screen. Get ready for a bigger, more immersive gaming experience that pulls you deeper into the action.

The 800R Curve: Surround Yourself in the Action

Serious Connectivity for Serious Gamers

For next gen console gaming or PC gaming, with HDMI 2.1, DisplayPort 1.4 and USB Type-C (65W power delivery), UltraGear's versatile connectivity enables high-resolution graphics, and fast, fluid gaming.

Customize Your Screen View with the Switch App

    Learn more about Monitors

    Computer Monitor
    With all of the focus on new 4K TV technology, many people don't realize that there are also lots of computer monitors with Full HD and 4K Ultra HD screens. A large, new, crystal-clear monitor is a great way to get the full, immersive experience your laptop or desktop computer is truly capable of. The big, bold graphics and crisp, infinite details of the monitors will change the way you use your computer, from mundane tasks like surfing the Web to engrossing experiences like graphics-intensive gaming and Full UHD movies and video. EVERYTHING will look multiple times better with a super high resolution monitor.

    What is the Best Monitor to Meet Your Needs?
    When shopping for a new computer monitor or display, you might be overwhelmed by all the choices of display types. Don't worry, CompSource can help you make sense of the various kinds of monitors, whether you're looking for a PC monitor or a Mac-compatible monitor. You will also need to know what type of connection your computer has, VGA, HDMI, DVI, Display port, etc. Will you want some built-ins like speakers, microphone, webcams and USB hubs.

    Monitor Display Types
    Many monitors use a liquid-crystal, or LED displays. This type of computer screen produces a quality image and can do so at a competitive price. Light-emitting diode, or LED and Edge LED monitors are LCD monitors, but they use backlighting to produce even brighter, more vibrant images, all while consuming less power in a thinner design than basic LCD computer monitors.

    If you like your iPad or iPhone you will love a monitor with in-plane switching, IPS monitors take things to the next level with wider viewing angles, more precise colors, and darker blacks than even the best LCD and LED computer monitors. These models are a perfect choice if your work and play finds you editing photos or enjoying video games.

    Touchscreen Computer Monitors
    Another option to think about are monitors supporting touchscreen capability. These are perfect for home entertainment and using a computer with kids. Swipe effortlessly through images, launch programs with the touch of a finger, or enjoy addictive touch-based gaming. If you do decide on a touch-screen monitor, focus on models with stands that can easily be adjusted and that have glass that extends all the way to the edge. Don't forget your screen protectors and cleaning kits to keep your touch-screen monitor clean and protected.

    Digital Signage
    Digital signage is a sub-segment of monitors. Digital displays use technologies such as LCD, LED, projection and e-paper to display digital images, video, web pages, weather data, restaurant menus, or text. They can be found in public spaces, transportation systems, museums, stadiums, retail stores, hotels, restaurants and corporate buildings etc., to provide way-finding, exhibitions, marketing and outdoor advertising.

    Whiteboards
    Interactive Whiteboards have a variety of features to enhance your meetings and presentations. Easy USB connectivity to a PC or Mac computer allows you to bring audiovisual content from your computer to a public audience through the use of a connected projector. Show videos, presentations, web pages and documents with ease. Many interactive whiteboards allow you to modify content with the simple touch of a fingertip. Some models allow you to write on the surface via dry-erase markers or with an electronic pen that functions similar to a computer mouse, allowing you to make changes to a document without having to go back to the computer.
