Monitor powering on but not showing any display


Recommended Posts

You have the screen enabled in Mac display settings?

 

Also, your back light might be dead. Does it work on another computer, perhaps? Just to verify.

 

Very unlikely, but the adapter or HDMI cable might be dead.

I never used Mac, so just the display settings "might" not have the second display detected. Years, years ago we had to do this in Linux, too.

 

HDMI can be DOA. But test that monitor on a different PC just to be sure. :)

Not sure if it so works on newer displays, have not had one go out, but I used to use a flash light to tell if the back light died.  Shine the light on the screen and should be able to make out something.

It always seemed to work for me. /shrug

 

Why putting it on a different computer will varify that issue. Or you can use a flashlight, too..

What adapter you using? I mean what brand and which one? (That shouldn't really matter)

Have you go to setting and detect/enable dual display? (I had to do that on mine)

Is HDMI cable at it's faults? (Could be faulty cable or the cable don't support your desired resolution)

Yeah I can see the windows very lightly on the screen in the dark.

 

Does the brightness need to be turned up or is it the backlight that has gone?

Adjust the brightness and if that does not work, back light has prob gone out.

External monitor still under warranty? If not, you can get a new screen for cheap.

 

Just tell us the model number of your screen. Looks like an Acer.

Start on page 18.  But as already noted, if your backlight is dead, which is the way it sounds, then you will not see a menu display on the monitor.

Monitor is around 100 USD on eBay. So, if it isn't under warranty, just ditch it. It's not worth repairing. You'd spend as much money for a new one than repairing it...

    • Amazon may use OpenAI and Nova models after Anthropic reportedly raises costs by Karthik Mudaliar Amazon is reportedly considering to use OpenAI models and even its own Nova family of AI models after Anthropic raised the cost of using Claude inside Amazon services. According to a report from The Information, Amazon is weighing its options to reduce costs under a new arrangement with Anthropic. But back in April, Amazon said it would invest $5 billion more in Anthropic, with the possibility of adding up to another $20 billion if certain commercial milestones are met. That investment actually came on top of another $8 billion Amazon had already put into the Claude maker. Anthropic, meanwhile, committed to spend more than $100 billion over 10 years on AWS technologies, including Amazon’s Trainium chips. Amazon isn't just a customer of Anthropic but also one of the most important backers and cloud partners. This is why it makes it interesting that Amazon is considering other alternatives to handle its internal workloads. Although Amazon has been building its own options for a while now. Its Nova family of AI models was announced in late 2024 for Amazon Bedrock, with models aimed at text, image, and video tasks. Amazon pitched the model around cost and latency at that time. With that said, OpenAI has also become a more realistic option recently for AWS customers as well as for Amazon itself. Earlier this year, OpenAI brought its latest models and Codex coding agent to Amazon Bedrock, after changes to its previously more restrictive Microsoft cloud arrangement. This allowed AWS to serve even those customers who wanted other alternatives from Claude, without having to move workloads out of Amazon's cloud. Evaluating alternatives could also be due to commercial pressure and not necessarily a sign of a damaged partnership between Amazon and Anthropic. Whether or not Amazon is actually considering switching entirely to OpenAI's models or its own Nova models remains unknown at this moment.
    • Samsung introduces new AI classroom tools and interactive displays at ISTELive 2026 by Fiza Ali Samsung has announced several new education-focused software features and interactive displays for schools during ISTELive 2026, taking place in Orlando, Florida, from 28 June to 1 July. The focus of these updates is on making shared classroom displays easier to use for teachers while giving IT administrators more control over managing devices. One of the key additions is the Samsung Account Management Solution (AMS). In many schools, multiple teachers share the same interactive display throughout the day, which means signing in and setting everything up can become repetitive. With AMS, teachers can log in by scanning a QR code or tapping an NFC-enabled ID card. Once signed in, their personalised workspace, including wallpapers, bookmarks, app shortcuts, and files, can be instantly accessed through Home Personalisation. Samsung has also included a screen lock feature, allowing teachers to lock the display if they need to step away briefly. Furthermore, the company is also updating its Education Portal with new tools designed for school IT administrators. The portal will allow IT administrators to register teachers, enrol devices, and manage user access from a central dashboard. Administrators can also link NFC cards to teacher accounts, making sign-ins quicker across shared displays. Another addition is a Tags feature that lets schools organise displays by building or classroom. Those tags can also be used to send emergency notifications to selected Samsung Interactive Displays through compatible platforms such as InformaCast and Raptor. Moreover, the tech giant's AI Assistant is gaining several new features aimed at supporting everyday classroom tasks such as lesson planning and classroom engagement. One of the features is Circle to Search, which lets teachers circle text or images on the display to quickly find related information, videos, or web results without interrupting the lesson. The content can then be brought into Samsung Whiteboard. Another feature, Live Transcript, converts spoken lessons into real-time captions, which could be useful for students with hearing impairments or those in multilingual classrooms. The AI Assistant also introduces AI Summary and AI Quiz. The summary tool creates summaries of recorded lessons, while AI Quiz generates questions based on lesson content so teachers can quickly check how well students are following along. Teachers signed in through Samsung AMS can also return to their previous AI-generated lesson materials without logging in again. Alongside the software updates, Samsung has expanded its Android-based Interactive Display range with three new models: the WAF-S, WAFX-PS, and WAHX-M. The WAF-S and WAFX-PS ship with Android 16, bringing updates to security, accessibility, and overall usability while maintaining compatibility with Google's education services including Google Classroom and Google Drive through EDLA certification. Meanwhile, the new WAHX-M is the biggest addition to the lineup, introducing a 98-inch display for larger spaces such as lecture halls and conference rooms. It will also be available in 65-inch, 75-inch and 86-inch sizes. Samsung says the WAHX-M further includes on-device AI features such as voice commands, text-to-speech, and an AI calculator, alongside support for Samsung AMS and AI Assistant. Samsung AI Assistant has been available since April, while Samsung AMS and the updated Education Portal will begin rolling out in July.
    • It's been $24 (single) or $89 (4-pack) for many days on both Amazon and Walmart as far as I know. That isn't a big discount. If these end up like the 1st gen, the 4-pack will routinely get down around $80, give or take a dollar. I think they have even hit $69 at times.
    • Microsoft brings Claude to its own Azure infrastructure, powered by Nvidia GB300 Blackwell by Karthik Mudaliar Anthropic's Claude models are now generally available in Microsoft Foundry on Azure and are running on Nvidia's GB300 Blackwell Ultra systems. Nvidia wrote in its announcement that the models are hosted on Microsoft Azure and accelerated by GB300 Blackwell Ultra GPUs, with Quantum-X800 InfiniBand networking used to support larger agentic systems and specialized sub-agents that can operate across business domains. This is great for customers and enterprises that want to build autonomous and domain-specific AI agents using Claude without moving outside Microsoft’s cloud platform. Microsoft currently offers Claude models in Foundry in two forms: “Hosted on Azure,” which runs end-to-end on Azure infrastructure and is generally available, and “Hosted on Anthropic infrastructure,” which remains in preview. This separation is quite important for organizations that have procurement, compliance, data processing, or internal governance requirements tied to Azure. Anthropic currently has 11 Claude models listed in Microsoft Foundry, including Opus 4.8, Sonnet 4.6, and even the unavailable Mythos and Fable models. Billing is handled through Claude Consumption Units (CCUs). Microsoft says CCU is an invoicing unit for Claude models in Foundry, with token usage converted using Anthropic’s published per-model token rates. The usage is billed through Azure Marketplace just like models from other distributors and appears on the customer's Azure invoice, while eligible spend can count against a Microsoft Azure Consumption Commitment. For starters, GB300 NVL72 is a rack-scale, fully liquid-cooled system that combines 72 Blackwell Ultra GPUs and 36 Grace CPUs. Nvidia has listed 37TB of fast memory, 130TB/s of NVLink bandwidth, and FP4 Tensor Core performance of up to 1,440 petaflops with sparsity. The deal is also part of a three-way partnership between Microsoft, Nvidia, and Anthropic. Under the deal, Anthropic has committed to buying $30 billion in Azure compute capacity and contracting additional capacity up to one gigawatt. Nvidia and Microsoft also said they would invest up to $10 billion and $5 billion in Anthropic, respectively.
    • WhatsApp is getting usernames, and you can reserve your preferred one now by Fiza Ali Sharing your phone number isn't always something you want to do, especially with people you've just met. Whether it's someone from a class, a local community group, or a sports team chat, handing over your number can feel like giving away more personal information than necessary. That's exactly the problem WhatsApp is trying to solve with its upcoming usernames feature. The company has announced that users can now reserve a unique WhatsApp username ahead of the feature's wider rollout later this year. Once usernames become available, they'll let people connect without revealing their phone numbers. It's a change that makes a lot of sense for group chats. Right now, everyone in the group can see your phone number. With usernames enabled, that won't necessarily be the case when someone contacts you for the first time. WhatsApp says it's opening username reservations early because more than three billion people use the app, meaning plenty of people are likely to want the same usernames. Reserving one now gives users a better chance of securing the name they actually want before the feature launches more broadly. If your preferred username is already taken, WhatsApp will also offer a built-in username generator to suggest available alternatives. The feature isn't only aimed at individual users. Creators, businesses, and organisations will be able to claim the same username they already use on Instagram or Facebook, making it easier to keep a consistent identity across Meta's apps. Furthermore, privacy is a big part of how WhatsApp is introducing usernames. There won't be a public directory where people can browse or search for usernames. Instead, people will need to know your exact username before they can start a conversation with you. Additionally, users can also choose to enable a username key, which adds another layer of control by requiring people to enter that key before sending a message. Once the feature rolls out, people who choose to use a username will no longer have their phone number shown when messaging a person or business for the first time. If you want to reserve a username, make sure you're running the latest version of WhatsApp, then head to Settings > Account > Username. The tech giant says usernames will roll out gradually over the coming months, and users will receive an in-app notification when the feature becomes available in their country.
