Is It OK to Use a TV as a Computer Monitor?
Yes. People have been using TVs as monitors since the advent of the home computer. Computer and TV screens rely on the same evolving technologies, from vacuum tubes to LCD technologies. Today, most TVs support HDMI or Wi-Fi, allowing them to connect with your computer wirelessly or with an HDMI cable.
Is It OK to Use a 4K TV as a Monitor?
All 4K TVs support HDMI or DisplayPort, so as long as your TV has a compatible port, you can connect it to your computer. Even if you have a 4K TV, it won’t display your desktop in Ultra HD unless your computer has a video card that supports 4K resolution (3,840x2,160 pixels). There are also ways to mirror your screen wirelessly from a computer or mobile device. However, to take advantage of 4K, you must use a wired connection.
How Do I Use My 4K TV as a Laptop Monitor?
First, make sure 4K is enabled on both devices (if both are capable, they are already likely set to display in 4K). After that, plug one end of the HDMI or DisplayPort cable into the TV, then insert the other end into your computer. Once you have a picture, you may need to change some settings to optimize the display. For example, text can appear very small on high-resolution displays from afar, so you might need to adjust the default font size on your computer. Many programs, including web browsers, also allow you to make text larger. One common issue you need to address is overscan, or when part of the computer’s display is outside of the viewing area. To fix overscan in Windows 10, you may need to adjust your TV and computer’s aspect ratio settings. Although it may sound counterintuitive, lowering the sharpness setting on your television can make the image clearer. While you’re at it, turn off any other features intended to enhance details. If you’re a gamer, another critical factor is input lag or the amount of time it takes to render your computer’s display. A fraction of a second can make a big difference, so check if your TV has a PC or Game mode to minimize lag.
