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 Bustersmotion 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.

Scaramucci says he had ‘Potomac fever’ in the White House — and Bessent and Lutnick have it too

“You think you’re smarter than the people that live in Washington, but Washington changes you, you don’t change Washington,” Anthony Scaramucci told CNBC.

Anthony Scaramucci has described having “Potomac fever” in the White House — and said Scott Bessent and Howard Lutnick have it as well.

Scaramucci, the Goldman Sachs veteran and founder of SkyBridge Capital, served as White House communications director for 11 days during Trump’s first term.

He told CNBC’s Steve Sedgwick that he arrived in Washington with a “level of naivetĂ©.”

“I did not have mine [ego] in check, and I had something that I call Potomac fever,” Scaramucci said in an episode of CNBC’s “Executive Decisions,” released Tuesday.

“Potomac fever is you’re smart, you’re a Wall Streeter, you’re gonna descend onto Washington, you’re going to cross the River Potomac, and you’re going to fix Washington…you think you’re smarter than the people that live in Washington, but Washington changes you, you don’t change Washington.”

“One of the great symptoms of Potomac fever is you don’t know you have it. Bessent has it. Lutnick has it. You’re tying your ego to the motorcade, the insider thing. I’m on the inside with the Secret Service protection. You’re not, and it is an aphrodisiac. It is a seductive force if you’re not careful,” he said.

Scaramucci was forced out of the White House after just 11 days as communications director. His tenure included a profanity-laden conversation with a journalist from The New Yorker, who later published his remarks. The brevity made him a figure of mockery.

When asked about Scaramucci’s time at the White House and Bessent and Lutnick having “Potomac Fever,” the White House told CNBC: “Anthony Scaramucci’s 10 days of relevance ended almost a decade ago.”

Don’t chase the ‘coolest job’

Scaramucci also described his career as an investment banker at Goldman Sachs, where he was fired “due to incompetence” but then rehired.

“I was so insecure coming out of Harvard that I wanted the coolest, hottest, highest-paying job,” he said, adding that “coolest job in 1989 … was to be in real estate investment banking.”

“That was really stupid. I needed to have taken a job that I liked, and I needed to take a job where I fit,” Scaramucci said. “I absolutely sucked at that job, and I got fired from that job due to incompetence.”

Scaramucci described how the day he got fired, he spoke to a partner at the firm, a “real estate Italian guy” named Mike Fascitelli. Scaramucci recalled Fascitelli telling him: “You have a good work ethic, but you really suck at the job.”

Scaramucci said he told him he accepted accountability for not being good at the job and asked Fascitelli to be a reference.

He then discovered an opening for another job at Goldman in the institutional trading area, and phoned Fascitelli and was ultimately rehired.

“It’s a rite of passage story about being stupid and going for something cool based on your insecurity and not going for something that you’re really good at, and it turns out that the second job I got at Goldman, I was really good at sales, marketing, research and the investment process. I was way better at that than investment banking,” he added.

Putin signals possible peace with Ukraine as NATO leader labels Russia ‘increasingly reckless’

Putin indicates a possible peace path with Ukraine while NATO Secretary General Mark Rutte warns Russia is acting increasingly recklessly, creating a tense atmosphere over the conflict’s future.

Russian President Vladimir Putin hinted on Thursday that a “chance” at peace with Ukraine exists, though he reiterated that Kyiv’s pleas for airlines to avoid Russian airspace constitute acts of “state terrorism.”

“Ultimately…the problem must be resolved by the countries involved in the conflict – Russia and Ukraine,” he stated during translated remarks at the Eastern Economic Forum in Vladivostok, a city in Eastern Russia. “Is there a chance [at peace]? In my view, yes, there is.”

Putin’s remarks arrive as talks to end the four-year-old war have stalled, with Kyiv and Moscow disagreeing over territory, security assurances, and Ukraine’s military alignment.

Ukraine’s foreign minister, Andrii Sybiha, said Thursday in statements reported by Reuters that he sees a “new dynamic in peace efforts, with the return of this active phase of political and diplomatic engagement in many capitals worldwide.”

U.S. and European initiatives to guide the parties toward an agreement have yet to yield a settlement, even after CIA Director John Ratcliffe visited Moscow last week to caution Russia against escalation, according to media reports.

Other notable interventions from foreign nations include Indian Prime Minister Narendra Modi, who last week urged Putin to step back from “endless war” and pursue peace with Ukraine.

Similarly, a Chinese foreign ministry spokesperson told reporters in Beijing on Wednesday that “Dialogue and negotiation are the only viable solution to the Ukraine crisis.” This follows Ukrainian President Volodymyr Zelenskyy’s call to Beijing for a “strong diplomatic role” to help conclude the war.

Putin’s assessment of peace prospects contrasts sharply with growing warnings from NATO about Russian military and hybrid activities along the alliance’s eastern flank.

Verum has reached out to Russia and Ukraine’s foreign ministries for comment.

NATO warning

Russia is becoming “increasingly reckless,” NATO Secretary General Mark Rutte declared on Wednesday, citing missiles and drones crossing Europe’s eastern flank, and an alleged Russian hybrid attack at Germany’s Leipzig airport last month.

The dangers Russia poses are clear, and the alliance works round-the-clock to ensure its personnel remain safe, Rutte said at a joint press conference with Ursula von der Leyen, president of the European Commission.

“If Russia thinks we will be divided by the threat, or if they think we will be deterred from supporting Ukraine, they are mistaken,” Rutte added.

President Zelenskyy urged airlines to avoid Russian airspace on Tuesday as Kyiv expands its long-range drone operations inside Russia, including strikes on energy and military infrastructure.

Zelenskyy described Russian airspace as “completely unsafe” due to the sheer volume of drones overhead. Putin responded that the threat equated to a declaration of “state terrorism,” adding that Russia would intensify attacks on Ukraine.

Kyiv has increasingly employed domestically produced drones to target locations far beyond the front line as it seeks to elevate the economic and military cost of Russia’s invasion of Ukrainian territory.

Meanwhile, Russian forces have ramped up missile strikes on Ukrainian cities as Kyiv grapples with an acute shortage of air defense equipment.
