Best Gaming TV for 2026: Get the Lowest Input Lag and Highest Picture Quality

In every CNET TV review, I compare three or more similar TVs side by side in a dedicated, light-controlled test lab. With each review, I employ a rigorous, unbiased evaluation process that has been honed by more than two decades of TV reviews. I test TVs with a combination of scientific measurements and real-world evaluations of TV, movies and gaming content.

To ensure I can evaluate the picture quality of every TV, I connect each one to an AVPro Connect 8×8 4K HDR splitter so each one receives the same signal. I test the TVs using various lighting conditions, playing different media, including 4K HDR movies and console games, across a variety of test categories, from color to video processing to gaming to HDR.

In order to measure each TV, I use specialized equipment to grade them according to light output and color. My hardware includes a Konica Minolta CS-2000 spectroradiometer and a Murideo Six-G 4K HDR signal generator. I use Portrait Displays CalMan Ultimate software to evaluate every TV I review according to its brightness, black levels and color.

I play a variety of games from an Xbox Series X or PlayStation 5, and note the effects of gaming modes and settings as well as the 4K/120Hz and VRR input capabilities. Helpfully, the Xbox includes a 4K/120Hz and HDR compatibility test: Settings>TV and display options>4K TV details. The page will detail the HDR modes it supports (including Dolby Atmos) and whether it will support VRR — if a TV gets ticks in all the boxes it means it has the best compatibility with high-end Xbox games.

Our reviews also account for such things as features, design, smart TV performance, connectivity including HDMI inputs and gaming compatibility.

Measuring input lag (in milliseconds) is an important component of my process for testing gaming TVs.

Check out the page on how CNET tests TVs for more details.

Input lag will often be lower in game mode than in any other mode on your TV. Here are a few more gaming-specific aspects I looked at for each TV.

How to turn on game mode. In most cases, viewing in game mode isn’t automatic, so you’ll have to turn it on manually, and sometimes the gaming monitor setting can be difficult to find. Many use a picture mode called “Game” while some, like Samsung and Vizio, let you apply game mode to any setting.

Game mode makes a difference, but not at all frequencies. As you can see in the table above, many TVs cut lag substantially when you turn on game mode, but plenty don’t. In general, expensive TVs with elaborate video processing get more of a benefit when you engage game mode. Additionally, and as I noted above, the Boost mode on LG OLEDs only works on 60Hz and not 120Hz.

Most TV game modes are good enough for most gamers. No matter how twitchy you are, it’s going to be tough to tell the difference between 10 and 30 milliseconds of input lag. Many gamers won’t even be able to discern between having game mode on and off — it all depends on the game and your sensitivity to lag.

Turning game mode on can hurt image quality (a little). TV-makers’ menus often refer to reduced picture quality. Reduced picture quality is generally the result of turning off that video processing. In my experience, however, the differences in image quality are really subtle with console gaming, and worth the trade-off if you want to minimize lag for a great gaming experience.

4K HDR gaming lag is different from 1080p. The display resolution you play at has an impact, and since new consoles prominently feature 4K HDR output for games, I started testing for 4K HDR lag in 2018. In general, the numbers are similar to the lag with standard 1080p resolution, but as you can see from the chart above, there are exceptions.

Testing is an inexact science. I use Leo Bodnar lag testers. Here’s how they work, and how I use them. I use two of these Bodnar lag testers — one in 1080p and one in 4K HDR — which use onboard optical sensors to measure and report input lag. When plugged into an HDMI port, the Bodnars make the screen flash in three different places and you place the unit’s onboard optical sensor flush onto the screen at these points. They calculate the lag at each position and you average the three readings to get a score. You might see different lag test results from different review outlets, which may use Bodnar or another method.

It’s easy to assume that vehicles all had internal combustion engines until very recently. Gasoline and petrol engines were the standard for decades, after all, so why would early vehicles be any different? In reality, the early days of the automobile era were more varied than you might expect, and even featured a range of electric cars. Yes, despite electric vehicles not truly taking off until the 21st century, the first electric vehicles are much older than you think; drivers in the 1900s were going around town in electric vehicles — and where there are EVs, there are charging stations.

One such station, visible in the image above, was the creation of General Electric. Formally called the mercury arc rectifier, it took alternating current and sent it through vaporized mercury in a glass tube. This converted it into direct current, which powered up the EV’s battery. The woman in the image, who’s charging a Columbia Mark 68 Victrola, is standing at the control panel, which allowed a user to adjust power levels. 

These chargers could be installed everywhere, including homes, businesses, and public parking garages, supporting the electric vehicle boom of the early 20th century. While 21st-century EV chargers have come a long way from where they were, the basic building blocks are all still there, and it’s fascinating to see.

How EV chargers have evolved since the early 20th century

EV charging has changed a lot in some ways — but not in others. At the core of it all is the aforementioned conversion from AC to DC, which still happens when you charge modern EVs at standard charging stations. The difference is that your vehicle’s on-board charger performs the conversion, not the charger. Old EV chargers took between several hours and a day to charge, and current-day units can similarly take a few hours to well over a day from empty, depending on the charger’s speed. Fast chargers, which provide DC directly, can cut this down to around an hour or less.

Old-school and modern EV chargers also differ in how they provide power to the vehicle. Mercury arc rectifiers connected directly to the negative terminal of the lead-acid battery that needed charging. Nowadays, EVs use dedicated charging ports. Battery swapping was also commonplace in the early 1900s, and companies like General Electric tried to cash in by offering to replace drivers’ old, run-down batteries with new ones for a fee. That’s not yet possible with most mainstream EVs, although companies like Stellantis have tried to introduce EV battery swapping with moderate success.

Even if they were unrefined compared to today’s models, early EVs seemed to be on to something. Why, then, did electric cars fail, and how did gasoline end up becoming the predominant power source for vehicles?

What led to the downfall of the original wave of electric cars

EVs were no mere fad in the 1900s and 1910s. According to the 1900 United States census, 1,575 of the 4,192 vehicles sold that year were electric, with the value of these early EVs — $2,873,464 — accounting for more than half of the total market value of $4,899,443. It wasn’t just EVs, either; other sources of propulsion, like steam, were also vying for a foothold in the automobile market. By the 1920s and 1930s, though, these had all been superseded by the internal combustion engine.

One of the major drawbacks of early EVs was the fact that electricity was not yet widely available. Electrical hookups were a rarity outside of major cities, limiting the use of these vehicles. The lead-acid batteries they used also had their fair share of issues. They needed to be inspected, cleaned, and repaired every few days, making them more of an inconvenience than anything. Worse yet, they had poor mileage, and, with chargers possibly out of reach, many likely didn’t want to risk being stranded while out for a drive.

Eventually, price reductions for gas cars and improvements such as electric starters and better reliability prompted buyers and automakers alike to move away from electric rides. Thus, while the best-selling EVs of 2026 show that it’s a good time for EVs, this electric boom plainly isn’t the first of its kind. Early EVs eventually fizzled out, but they still set the stage for our current fascination with electric vehicles.
