How to Use Roku TV as Computer Monitor? Easy Guide

You are far from the first to imagine what it might be like to have a large desktop monitor. Consider how much multitasking and immersive gaming you could accomplish with a 50- or 60-inch monitor rather than a 24-inch monitor!

However, when monitors become more significant, they become prohibitively expensive. However, you undoubtedly already have a large screen in your home such as a Roku TV.

While a Roku TV can use as a computer display in most circumstances, this is not always the ideal solution. Here’s everything you need to know How to Use Roku TV as Computer Monitor and why you probably shouldn’t.

Indeed, it is likely to be less appealing, convenient, and usable than you believe. There’s a reason that dirt-cheap 32-inch HDTVs aren’t flying off the shelves to serve as affordable jumbo screens. 

The most convenient way for using a Roku TV as a computer monitor is via wireless casting. Streaming devices such as Roku, Google Chromecast, and Apple TV enable you to share the output of your computer’s display with any screen you choose. However, several critical points to consider to ensure a smooth transition.

Is It Possible to Use a Television as a Computer Monitor?

You may indeed use a television as a computer monitor, though experts would have advised caution even two years ago. What has altered? Today’s televisions manage to fit more pixels for less screen space and respond more quickly to mouse and trackpad inputs than in the past.

Casting is another game-changer when using a television as a computer monitor. Google Chromecast or Miracast-enabled devices can transform your living room into an on-demand home office. 

Why Would You Use a Television as a Monitor?

Using television as a computer monitor was not viable during the digital dark ages. Computers had their rooms, complete with specialized desks and peripherals, as well as a squid-like network of dusty wiring. 

Today’s significantly larger televisions with their ultra-high resolutions and vibrant colors indicate the end of the era of the “computer room.”

However, several factors to consider initially, like PPI, lag time, streaming devices, and understanding which TV to use as a monitor. Once you grasp the fundamental facts, you’ll be able to put an end to the dispute about whether to use a computer monitor or a television.

Consider the Following HD TV Features

How to Use TCL Roku TV as Computer Monitor

Consider a few things if you wish to utilize a Roku TV as a computer display.

Verify your PPI

PPI means Pixels Per Inch. A 4K Roku TV contains the same pixels, but they are distributed more sparsely across a significantly larger area.

It is critical when using a television as a monitor, as some older televisions do not have high PPI ratings. Your papers and online pages may appear a little blurry with a low pixel count.

Two years ago, the low PPI was the most compelling reason to avoid using a television as a computer monitor. So you can determine the PPI of your Roku television. Consult the owner’s manual or conduct a Google search for the product code and the term “PPI.” 

Response Time

Response times for high-definition Roku televisions and computer monitors can vary significantly. HDTVs favour vibrant colours, increased contrast, and broader picture quality, contributing to a slower response time. Computer monitors typically sacrifice image analysis and viewing angles to achieve faster response times.

Certain HDTVs include a “game mode” setting that disables some visual processing to improve input lag and reaction time. If you plan to play PC games on your Roku TV, you should check the options menu of your HDTV to see if this capability is available.

Refresh Rate

The refresh rate indicates how frequently it “refreshes” or redraws its image per second. The majority of current displays have a refresh rate of 60Hz, which implies that the image refreshes 60 times per second.

However, you’ve seen premium monitors and high-definition televisions with more excellent stated refresh rates are 120Hz, 144Hz, or even 240Hz. It can be unclear, as a computer monitor with a refresh rate of 120Hz is not necessarily the same as an HDTV with a refresh rate of 120Hz.

That’s because the programming that people view on television is either 24 frames per second (fps), 30 frames per second (fps), or 60 frames per second (fps).

The material that people would view on a computer monitor can vary significantly. Many videogames can output frame rates greater than 60 frames per second if the graphics card is powerful enough.

Examine Your Lag Time

Serious gamers are concerned with the time between controller or mouse inputs and on-screen activities. It refers to as “input lag.” Consider whether you care about utilizing a television as a computer monitor before proceeding.

If the answer is “yes,” you may determine your television’s input lag online using a database or by simply searching for “input lag” and your television’s model number.

If you wish for the latest television to use as a computer monitor, look for one with little input latency. The good thing about today’s new televisions is that most of them significantly reduce lag times.

The majority of us cannot detect lag periods shorter than 40 milliseconds (ms), although there are dozens of excellent sets available with lag times ranging from 5-15 ms. In either case, everyone but the most dedicated gamers will be unaffected by increased latency times.

How to Wirelessly Utilize Roku Television as a Monitor?

The most attractive feature of utilizing a smart Roku TV as a computer monitor is the absence of cords. If you’ve ever desired connector cables to disappear and your flooring would be free of possible injuries, then it is the best option. Chromecast, Roku, and other casting or streaming technologies elegantly address the Roku TV-as-computer-monitor problem.

The first step is to determine which streaming device to use. There are various options, like Google Chromecast and Roku. They are USB sticks or dongles in flash drives that plug into the HDMI port on a television.

All central streaming units are available in 3K and 4K resolutions. It is critical to get the 4K version. While the 3K devices perform well for video, they do not work well when used as a computer monitor. A 3K streaming equipment will stifle the image quality and create a bottleneck.

Once you’ve chosen a casting device, connect it to the HDMI port on your television. There is a brief configuration process, but someone can complete it in minutes to install an app.
