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.

Your Phone’s a Germ Magnet. How to Disinfect It Properly

Want to keep your iPhone or Android germ-free? Follow these phone cleaning tips.

Your phone goes everywhere with you — on your commute, your lunch break, even the bathroom (don’t lie). But for something that spends so much time in your hands and against your face, it’s probably way dirtier than you think. In fact, studies have shown that the average smartphone can carry more germs than a toilet seat. Yeah, really.

All that touching, tapping, swiping and setting it down on random surfaces adds up fast. If you’re not regularly disinfecting your phone, you’re basically carrying a pocket-sized petri dish. The good news? Cleaning it the right way is quick, easy and doesn’t require fancy gear. Here’s how to sanitize your device safely — without damaging the screen or frying your electronics..

The Federal Communications Commission suggests disinfecting your phone daily, but not all cleaning methods are safe. Harsh chemicals and abrasive materials can damage protective coatings and potentially harm your screen. To keep your phone both clean and intact, it’s crucial to use the right cleaning techniques.

We’ll guide you through the best methods and products for keeping your device germ-free, from iPhones to Samsungs, and whatever their level of water resistance may be.

For more cleaning tips, here’s how to clean wireless earbuds and AirPods.

What are the best products for daily cleaning?

After touching surfaces that see a lot of action from the public — such as door handles, seats on public transportation, grocery carts and gas pumps — you might think you need a heavy-duty cleaning agent to use on your phone. However, you should avoid rubbing alcohol or products made of straight alcohol, since they can damage the protective coatings that prevent oil and water from harming your screen.

Some suggest making your own alcohol-water mix, but getting the concentration wrong can damage your phone. The safest option is using disinfectant wipes with 70% isopropyl alcohol. For daily cleaning, consider a UV light product like PhoneSoap, which kills 99.99% of germs and bacteria. We can also turn to phone manufacturers and cell service companies for guidance, too.

Apple now approves using Clorox Wipes and similar disinfectants, which was not recommended before the pandemic since they were thought to be too abrasive on the screen’s coating. AT&T advises spraying a 70% isopropyl alcohol solution on a soft, lint-free cloth and wiping your device down. Samsung also recommends using a 70% alcohol solution with a microfiber cloth. Always make sure your phone is powered off before cleaning it.

What are the best methods for removing fingerprints, sand and makeup?

Sometimes your phone needs a more specific treatment when washing up. The recommended process for daily cleaning may not be enough to remove pesky grains of sand after a beach vacation or tough foundation stains.

Get rid of fingerprints

Fingerprint smudges are inevitable since your skin produces oils. Every time you pick up your phone, your screen will get fingerprints. The safest way to make your screen print-free is with a microfiber cloth. For a deeper clean, dampen the cloth with distilled water (never apply water directly to the screen) and wipe down the surface. This works for the back and sides of your phone as well.

Alternatively, try a microfiber screen cleaner sticker that sticks to the back of your phone for easy wiping.

Remove sand and small particles

Grains of sand and lint can easily get stuck in your phone’s ports and crevices. To remove it, we recommend you use Scotch tape. Press it along the creases and speaker, then roll it up and gently insert it into the ports. The tape will pull out any debris. You can then just simply throw away the tape for easy cleanup.

For smaller speaker holes, use a toothpick gently or a small vacuum crevice tool to suck out the debris. These tools work well for other small appliances or hard-to-reach areas in your car too.

Cleanse makeup off your phone screen

When you wear makeup and skin care products, such as foundation and moisturizers, you’ll leave residue on your phone screen. While makeup remover works for your face, it’s not safe for screens due to potentially harmful chemicals. Instead, try a screen-safe makeup remover like Whoosh, which is alcohol-free and gentle on all screens.

Alternatively, use a damp microfiber cloth to clean your phone, then wash the cloth afterward. Make sure your cloth is only slightly wet to avoid soaking your phone in water.

What if my phone is waterproof?

For waterproof phones (IP67 and above), it’s best to clean the device with a damp cloth instead of submerging or running it under water — even if the phone advertises that it can withstand submersion for a certain amount of time.

Afterward, dry your phone with a soft cloth, ensuring all ports and speakers are patted dry. While your phone can withstand water, submerging it can lead to water in the ports, delaying charging. Remember, water resistance is meant for accidents, not swimming or regular cleaning.

Things to avoid when cleaning your phone

We’ve already covered why you should avoid makeup remover and rubbing alcohol, but those aren’t a comprehensive list of harmful cleaning agents. Here are a few other items and products you should never use to clean your phone:

Hand sanitizer: Fragrances and ethyl alcohol found in many sanitizers can harm your phone.
Window or kitchen cleaners: Harsh cleaners can strip the protective coating on your phone and leave it more vulnerable to scratches.
Paper towels: Paper can shred, making the debris on your phone much worse, and the rough texture can leave scratches on your screen.
Dish and hand soap: Most soaps require you to combine them with water, and since you should keep water away from your phone, it’s best to stick to a damp cloth.
Vinegar: Like cleaners and alcohols, vinegar will strip your phone screen’s coating.
Compressed air: Blowing intense and direct air into your phone’s portals can cause damage, especially to your mic. Apple specifically warns iPhone owners not to use compressed air.
