TV vs Monitor for PC Use: Ultimate Comparison Guide

Key Differences Between TVs and Monitors

As an electronics expert who enjoys gaming and streaming, I often get asked – which is better for PC use, a TV or a monitor? While both can work, there are some major differences in features and performance.

Resolution

Monitors are designed for close-up desktop work and gaming, so they pack in more pixels per inch (ppi). Average monitor resolution is 1920 x 1080 (Full HD) to 2560 x 1440 (Quad HD). Newer high-end gaming monitors go up to 3840 x 2160 (4K).

According to DisplayDB, the average ppi for a 27" monitor is ~90ppi. This results in sharper image quality and text.

TVs are made for farther viewing from a couch. They prioritize larger screen sizes, so have lower pixel density. Most current TVs are 3820 x 2160 4K, but on a 55" screen that equates to only ~80ppi. Fine for 8-10 feet away, but up close pixels are more visible.

Refresh Rate

The refresh rate is how many times per second the display updates with new image data. Higher is smoother.

Monitors dominate here with rapid 144Hz-240Hz refresh rates, versus the standard 60Hz on most TVs. Some TVs may have 120Hz modes.

Higher refresh rates reduce motion blur and deliver a more responsive, fluid feel. This is especially critical for PC gaming.

According to Tom‘s Hardware, a 144Hz gaming monitor provides almost 2.5X the frame rate of a 60Hz TV.

Response Time

Input lag is how long it takes for your mouse click or game controller input to display on-screen. Faster response means less lag.

Monitor response times range from ultra-fast 1ms for high-end gaming monitors, to 5-10ms for everyday models.

TVs have higher input lag, averaging between 15-40ms. Newer TVs are improving with gaming modes of 10-20ms.

Aspect Ratio

Monitors have a widescreen 16:9 aspect ratio, the standard for most desktop use and gaming.

Consumer TVs are transitioning to wider cinematic formats like 21:9 or curved screens. These look impressive for movies, but distorted for desktop work.

Features

TVs offer built-in speakers, TV tuners, and smart software for streaming apps.

Monitors focus on visual performance with gaming preset modes, Blue Light filters, and height/pivot adjustable stands. Most lack onboard audio.

Price

For the same display size, TVs are generally cheaper. A 50" 4K TV can be under $400, versus $700+ for a comparable gaming monitor.

But you pay more for a monitor‘s specialized features and performance. Consider your primary use case.

Using a TV as a Computer Monitor

Let‘s go deeper into using a modern 4K TV for PC desktop and gaming use.

Connections

First, your TV must have HDMI ports to connect your computer. Most TVs have 2-4 HDMI, while new models also include HDMI 2.1 ports. If your graphics card has DisplayPort, check if your TV supports DisplayPort over USB-C.

You CANNOT use old VGA ports. HDMI handles the digital signal for up to 4K resolution.

Matching PC Resolution to the TV

A 4K TV has a native display resolution of 3840 x 2160 pixels.

To avoid blurriness, your PC graphics card needs to match and output the same 4K resolution if your TV is 4K. 4K also demands a more powerful graphics card like NVIDIA RTX 30-series or AMD Radeon RX 6800/6900.

If your PC maxes out at 1920 x 1080, set your TV input label to 1080p rather than 4K.

Ideal TV Size for Monitor Use

Bigger may seem better, but giant TVs can be impractical up close as a PC display.

• For desktop use, a 32" TV offers solid pixel density without eyestrain. Avoid going over 40" for regular computing.

• Sit a proper distance back. Experts suggest 1.5-2X the diagonal screen size. So for a 32" TV, sit about 4-5 feet away.

Gaming Performance on TVs

Large-screen 4K TVs tempt gamers. But TVs aren‘t designed for fast-paced, competitive online gaming.

Some drawbacks of gaming on a TV versus monitors:

• Higher input lag causes controller delay. TV game modes only reduce lag to 10-20ms, versus 1ms for monitors.

• Lower 60-120Hz refresh means more motion blur in action scenes.

• IPS monitor panels have faster pixel response for crisper detail in motion. TV VA panels smear details in fast motion.

For casual, single-player games, a TV works fine. Hardcore gamers still need a high refresh gaming monitor.

Minimizing Input Lag

Use your TV‘s Game Mode option to reduce input lag by around 15ms. Turn off unnecessary video processing. Many new TVs also have Auto Game Mode detecting when a console is connected.

To compare, PCMag tested input lag across TVs and gaming monitors. The LG C1 OLED TV had superb 13ms lag with Game Mode enabled. But top gaming monitors scored less than 5ms.

Using a Monitor for TV

On the flip side, let‘s discuss using a monitor for TV and streaming instead of an actual television.

Connecting Devices

Monitors lack onboard TV tuners. Instead, you‘ll need to connect external devices like:

• A cable/satellite box
• Streaming stick like Roku or Amazon Fire TV
• Game console like PlayStation 5

Gaming consoles can usually just plug straight into HDMI ports. For streaming, make sure your monitor has built-in speakers or use headphones.

Audio Quality

Sound is a weak point for monitors – most don‘t have speakers at all.

Gaming monitors tend to only have basic 2W speakers meant for system alerts. Even monitors with speakers can‘t match a TV‘s audio.

Instead, connect external computer speakers, a soundbar, or simply use headphones for the best sound.

Aspect Ratio

Monitors excel as PC displays with a 16:9 widescreen aspect. This matches most content.

But for a truly cinematic movie experience, a TV‘s 21:9 or curved screen is more immersive. If you mainly watch movies and Netflix, a monitor has limited appeal.

Gaming Prowess

Gaming is where monitors shine over TVs as display devices. With their lightning-fast refresh rates and response times, monitors provide a very responsive, competitive gaming experience.

For eSports gamers, even millisecond advantages matter, so monitors are preferred. Resolution may only be 1920 x 1080 (Full HD) rather than 4K, but enables higher frame rates.

Monitor vs TV: Best Uses

Based on their respective strengths and weaknesses, here are the ideal uses for monitors versus TVs:

Monitors

• Everyday PC use – work, web browsing, content creation

• PC gaming, especially fast-paced competitive multiplayer

• Mixed desktop work and gaming use

• Secondary screen next to a TV

TVs

• Primary entertainment screen for casual gaming, movies, streaming

• Large screen for couch use and split-screen gaming

• Affordable 4K visuals

• PC gaming from the couch with controller

• Shared family/living room display

The Bottom Line

TVs and computer monitors can both function as display devices, but are designed for different primary uses.

Monitors prioritize sharpness and responsiveness for desktop PC use, with better text clarity and faster gaming performance.

TVs are made for big-screen entertainment with 4K resolution, smart apps, and immersive viewing angles.

Consider your own needs and setup. Monitors excel for serious PC gamers and workers needing top visual fidelity at a desk. TVs allow lounging on a couch to game, stream movies, or casually use a PC. Identify your priorities and choose the display type that best matches your activities.
