How CNET Tests Monitors

The method behind our monitor-review madness.

Monitor testing and evaluation consists of formal and subjective quality tests and hands-on assessment of the display’s design and features — connection selection and location, menus and options and overall behavior. As part of the process we use the monitor for tasks specific to its mission, such as everyday productivity, video streaming, image and video editing or different types of gaming (such as FPS or RPG). Note that we only report a fraction of our results, usually what’s necessary to adequately convey a monitor’s strengths and weaknesses for particular uses.

The process begins with unboxing and setup; it’s connected to our Windows-based desktop testbed (or a relatively high-end Mac in cases that require it) equipped with a current-generation Intel Core i9 and high-end Nvidia GeForce graphics card. Both the computer and monitor are plugged directly into a wall outlet to prevent any power issues that might impact performance.

We generally prefer to use our cables rather than the manufacturer-supplied ones since they’re a known quantity and tend to be higher quality; if we run into any issues, we double check using the manufacturer’s cables. DisplayPort is our primary connection for testing. If the monitor specifies any console-specific capabilities, we connect it to the relevant console(s), Xbox Series X and/or PS5 via HDMI.

Before any testing begins, we photograph the default settings and all menu options for reference and to determine the complete set of tests we’ll need to run on that particular monitor given its specific capabilities; how extensively we test depends on the capabilities of the monitor, the screen and backlight technology used, and the judgment of the reviewer. We disable power-saving measures where relevant, which can affect brightness and related measures (the option is mandatory per California law). We use a subset of these tests to evaluation laptop displays and run them both plugged into a wall outlet and on battery using the default profile but with screen timeouts disabled.

We also record any relevant information about the panel — manufacturer specs for resolution, color gamut and profiles, refresh rates and so on — that may impact our evaluation against manufacturer’s claims. While we review a display with the company’s publicly expressed target market in mind, we also consider the monitor’s suitability for other uses that might apply.Wherever possible, we download drivers and color profiles specific to the monitor.

What we measure

All measurements are performed using the most recent version of Portrait Display’s Calman Ultimate software using an X-Rite i1Display Pro Plus (rebranded as Calibrite ColorChecker Display Plus) and a variety of included patch sets, with additional HDR testing using a Murideo Six-G pattern generator and or the Client3 HDR patterns within Calman. We periodically spot check the colorimeter’s accuracy against the Konica Minolta CS-2000 spectroradiometer used for our TV testing.

Our test lab is equipped with blackout curtains to fully block ambient light, though complete darkness isn’t essential since the colorimeter sits directly on the screen and isn’t affected by dim lighting. The room has natural light and various artificial sources for normal usage evaluation.

Color accuracy results are reported in units of Delta E 2000. We perform most of the tests (where we know results vary) at both 100% and default hardware brightness levels.

Core tests — those we run on every display, regardless of intent or price — include:

White point, brightness (peak and minimum), contrast and gamma for sRGB and the native color space measured across 21 gray patches (0-100%), reported rounded down to the nearest 50K as long as there are no big variations. A variation of plus or minus 200K around the target color temperature is considered acceptable for all but the most color-critical displays.
Color gamut coverage and accuracy for sRGB and the native color space using Calman’s standard Pantone patch set plus grayscale and skin tone patches.
We add Blur Busters‘ motion tests for gaming monitors to judge motion artifacts (such as ghosting) or refresh rate-related problems.

If a monitor has menu options beyond the basics, we run the same core tests for the following settings when available:

All color presets
All gaming presets (such as FPS). We also test brightness for pixel overdrive and motion-blur reduction modes (which tend to lower brightness considerably).
Gamma for at least 1.8, 2.2 and 2.6
Color temperatures for at least 5000K, 6300K, 6500K and 9300K

For HDR, we add testing for HDR-specific presets (such as Game HDR or Cinema HDR) and brightness for window sizes of 1%, 5%, 10% and 100% of the screen.

Finally, there are tests we only run when needed to understand the measurements we’ve gotten or to confirm that artifacts we’re seeing — notably nonuniformity — aren’t imaginary.

Fubo Loses NBCUniversal Channels, Putting Your NBA Games in Jeopardy

Sound the carriage dispute Klaxon: Some network programming has disappeared from the streaming service after content negotiations fell through.

If you’ve noticed your favorite show has recently gone missing from Fubo, it’s probably because an entire block of programming just disappeared from the site’s channel lineup.

The live TV streaming service is engaged in a carriage dispute with NBCUniversal, a media company whose subsidiaries include NBC News, Universal Studios, Peacock, Telemundo and Illumination, among other brands.

On Nov. 21, NBCUniversal pulled all of its networks from Fubo. This is an especially big deal for sports watchers on the streaming service, since the Fubo Sports subscription — which began earlier this year — depends on the licensing agreement with NBCUniversal. However, viewers can still access sports content on networks like ESPN, CBS and ABC.

Fubo released a statement on Tuesday, alleging the media giant is engaging in «discriminatory tactics» that are harming the streamer’s subscribers.

«NBCU is discriminating against Fubo and our subscribers,» the statement says. «They allowed YouTube TV and Amazon Prime to integrate Peacock directly into their channel store, but refused to give Fubo the same rights.»

Fubo says NBCUniversal is trying to force a multiyear deal for certain channel packages under the media giant’s new spin-off media company, Versant, and that it’s trying to upcharge on the Fubo Sports subscription by adding «expensive, non-sports channels» into the agreement, increasing the cost.

According to NBCUniversal’s website, the Versant brands include CNBC, E!, MS Now, SyFy and USA, among other channels.

NBCUniversal did not respond to a request for comment.

Fubo says that it’s willing to move forward without NBCUniversal content if an agreement cannot be reached.

«Fubo is committed to bringing its subscribers a premium, competitively-priced live TV streaming experience with the content they love,» its statement concludes. «That includes multiple content options, including a sports-focused service, that can be accessed directly from the Fubo app.»

Fubo recently became an affiliate of The Walt Disney Company, following its merger with Hulu’s live TV platform in October. It’s unclear whether this merger affected content agreement negotiations with NBCUniversal. Fubo did not respond to a request for comment on this.

Spotify Will Reportedly Get More Expensive in the US Next Year. Here’s What to Expect

The music streaming service will reportedly raise prices again after subscription rate hikes in other regions.

After announcing it is raising prices in regions including Europe, South Asia and Latin America, Spotify is reportedly about to increase prices again in the US.

The US is included in the latest Spotify price hike on its Premium services starting in early 2026, according to the Financial Times, which cited three sources familiar with the streaming music company’s dealings. For now, the least expensive Premium plans in the US start at $12, but the price hike would likely put it in line with the other regions where the Premium plan costs about $14 a month.

Spotify also offers a Premium Family plan that covers six people in the same household for $20 and plans for students ($6 a month bundled with Hulu) and couples ($17 a month). Spotify also offers a Basic plan that does not include access to audiobooks for $11 a month. A representative for Spotify did not immediately respond to a request for comment.

A steady increase

If the report is accurate, this would be the third price increase on Premium plans in the US since 2023. Before those hikes, Premium plans were $10, but Spotify raised its minimum price by $1 in 2023 then again in 2024.

Just this week, Spotify added the ability to seamlessly import playlists from other music services including Apple Music and Tidal.

Spotify has faced some controversy this year, including some music acts abandoning the platform and some customers canceling subscriptions over advertising for Homeland Security’s ICE program. CNET has a guide for canceling your Spotify subscription.

The company is the market leader among music streaming apps with about 32 percent market share as of the end of 2024.

Some Rad Power Bike E-Bike Batteries Can Catch Fire, Consumer Protection Agency Warns

The company declined to offer full replacements or refunds, citing financial constraints.

The US Consumer Product Safety Commission is warning that some lithium‑ion batteries used in certain e‑bikes made by Rad Power Bikes pose a serious fire hazard that could lead to injury or even death. The agency says the batteries, identified by model numbers RP‑1304 and HL‑RP‑S1304, can unexpectedly ignite or explode, especially if the battery or its harness has been exposed to water or debris.

The recall has been marked as a «public health and safety finding» because Rad Power Bikes has declined to offer full replacements or refunds for all consumers, citing financial constraints.

CPSC reports 31 incidents of fire involving these batteries, including 12 cases where property damage totaled approximately $734,500. Some of these fires occurred even when the battery was not in use or charging, but was in storage.

The batteries were sold as either original or replacement units for several Rad Power Bikes e-bike models and were available through RadPowerBikes.com, Best Buy and independent bike shops nationwide.

«Rad informed the agency that its demand to replace all batteries, regardless of condition, would immediately put Rad out of business, which would be of no benefit to our riders,» the company said in a statement issued with the CPSC warning. «Rad is disappointed that it could not reach a resolution that best serves our riders and the industry at large. Rad reminds its customers to inspect batteries before use or charging and immediately stop using batteries that show signs of damage, water ingress, or corrosion, and to contact Rad so we can support our riders.»

The CPSC’s statement does not apply to all Rad batteries, and does not apply to its Safe Shield or semi-integrated batteries.

Consumers who have one of the affected batteries are urged to stop using it immediately and dispose of it properly via a household hazardous‑waste collection center. Do not place the batteries in standard curb-side recycling or trash bins, and refrain from reselling them.
