Can You Use a Roku TV as a Computer Monitor?

At a technical level, Roku TVs can absolutely be used as external monitors for laptops, desktops, and other devices like gaming consoles. But how well a Roku TV will serve as a computer display depends on a few key factors.

Roku TV and Monitor Specifications

Modern Roku TVs support 1080p (1920 x 1080) resolution at 60Hz refresh rate. Many also support 4K at 30 or 60Hz over HDMI 2.0. This matches up well with mainstream monitors. Higher end monitors offer better resolution (2K, 4K) and faster refresh rates (144Hz+).

Screen size may be the Roku TV’s biggest advantage as a monitor. They range from 24″ up to 75″+. Most monitors max out at 27-34 inches.

Connectivity Options

HDMI is the best way to connect a computer to a Roku TV. HDMI carries both video and audio signals. For HDMI 2.0 models, you can get 4K 60Hz resolution.

Other options are VGA, DisplayPort/miniDP (with adapters), and wireless casting. VGA only does 720p and has no audio. Wireless can be laggy for real-time work.

Setup Steps Depend on Platform

Using a Roku TV as a second display is plug-and-play for Macs and PCs with HDMI ports. Just connect the HDMI cable and set the Roku as an extended or mirrored display in System Preferences or Display Settings.

Setup is trickier for laptops without HDMI. You’ll need an adapter like USB-C to HDMI. Wireless screen mirroring also requires adjusting settings on both TV and computer.

Advantages of Using a Roku TV as a Monitor

Large Screen Real Estate

The main appeal is the Roku TV’s large display. Even entry-level models start at 24″, going up to 75″ for high-end units. Very few monitors exceed 27 inches. The spacious screen makes the Roku TV ideal for productivity. You can comfortably have multiple windows open side-by-side.

Dual Functionality

The Roku TV pulls double duty. You can use it as an external monitor while also enjoying the Roku’s smart features and streaming channels. Switching between PC display mode and Roku TV mode is as easy as changing inputs.

Cost Effective

You can get a 32″ to 55″ Roku TV for under $300. Comparable monitors often cost more. And the Roku TV adds streaming capabilities on top of being a monitor. Going bigger, Roku’s 70″ 4K models cost around $700. It would be over $1000 for a comparable 4K monitor.

Disadvantages of Using a Roku TV as a Monitor

Lower Resolution

Roku TVs max out at 1080p resolution unless you spend extra for a 4K model. Monitors can match or surpass Roku TVs here. Graphic designers and engineers may want higher res monitors for detailed work.

Lack of Ergonomic Adjustments

Monitors offer flexible stands with height, swivel, tilt, and pivot adjustments. Roku TVs simply have fixed VESA mounts. It’s harder to get an ideal viewing angle or line up multiple Roku TVs perfectly.

No Portrait/Pivot Option

Related to ergonomics, monitors can pivot to portrait orientation. Roku TVs are landscape only. Portrait mode is useful for coding, reading long documents, managing photos, etc.

Not as Portable

Monitors tend to be smaller and lighter than Roku TVs of the same screen size. Monitors are easier to transport for mobile professionals. Roku TVs work best as stationary displays.

Alternatives to Using a Roku TV as a Computer Monitor

Dedicated Computer Monitors

An actual computer monitor will offer better ergonomics, connectivity, higher refresh rates, and resolution. But monitors can’t compete with Roku TV’s large screen sizes at their low price point. It depends how much you want to optimize for computer versus streaming use.

Wireless Display Adapters

Wireless adapters like Google Chromecast, Miracast, and AirPlay allow you to mirror or extend your computer screen to a TV. There’s no need for HDMI cables. But lag and lower frame rates make wireless less suited for productivity work vs. entertainment.

All-In-One Desktop Computer

All-in-one computers integrate a monitor and PC into one device. Many models like the Apple iMac offer excellent displays equivalent to standalone monitors. But they lack the Roku TV’s big screen size, smart features, and flexibility to use as just a monitor.


Roku TVs make surprisingly capable monitors thanks to their affordable large screens, 1080p resolution, and standard connectivity options like HDMI. Basic setup is quick and easy for many laptops and computers. Just be aware of the limitations around resolution, ergonomics and orientation that monitors can improve on.

For productivity work, a dedicated monitor is still ideal. But for office and home uses where large screen real estate for documents and web browsing is more important than high FPS gaming, using a Roku TV as a computer display is definitely feasible. You get the benefits of both a smart TV and an external monitor for not much more than the cost of just a monitor alone.
