I just bought a Lenovo IdeaCentre H415 (it has an A6-3650 with Radeon 6530D GPU, VGA and HDMI output, but no DVI). My monitor supports VGA, HDMI and DVI. When it's plugged in via VGA, it works as you would expect. When it's plugged in via HDMI - nothing. I've looked around for some option in Display/Personalisation, but nothing is evident that would allow me to do this (nor in the Catalyst Control Centre).

it should work right away when you plug in the cord, so there are 3 possibilities

1. bad hdmi cord

2. the port on the laptop is bad

3. the port on the monitor is bad

(it's also possible, though unlikely, that the drivers weren't installed correctly. have you updated the catalyst drivers?)

well, there's more possibilities than that. i thought the sme as StrikedOut. the monitor may need to change its source.

i figured if that were the case it would still show as a detected output in ccc and screen rez window

since he didn't mention it appearing i figured it probably didn't

I had the same problem and when I read this thread, it dawned on me that I had not thought of there being an "Input Select" option in the monitor settings. Sure enough, that was all my problem was. Now, having my HP laptop connected to my ASUS monitor via HDMI works fine. I had just thought the monitor would work if you had a good connection to a source, but then again, I should have thought about how the monitor would handle it if you had more than one source connected simultaneously, like VGA and HDMI at the same time. In that case, it makes sense that the monitor would have to ask you what source you wanted to use or there would be a "Input Select" option to tell it what source/connection to use.

Another thing to note, when I changed the monitor input selection to HDMI, I had no audio/sound then. I figured the audio was being then sent thru the HDMI cable, but because my monitor doesn't have speakers (I didn't want a monitor with speakers... would rather have decent separate speakers) I wasn't getting any sound. Sure enough, that was it. Once I had opened my audio settings and set "Speakers and Headphones" as the default place/ports to send audio to, my audio/sound was back as usual.

I wasn't able to figure out which key launches the BIOS, but after a couple of reboots it ended up going off HDMI. I did have to do the input select on the monitor as well, which required a complete power cycle to get working. I didn't have the sound problem, possibly because I already have headphones plugged in?

Image quality is much better now.

OK. This isn't working out how I'd like. Whenever the system goes to sleep, it doesn't output anything when waking up. I have to plug VGA back in to have a chance at getting HDMI.

I checked the BIOS, and it only has the option to use Auto or default to a PCI-e GPU.

hmm, it sounds like the hdmi on your graphics card might just be faulty, there's no reason your hdmi should be acting like that, it should just work when it's plugged in unless you explicitly turn off that input yourself (which can only be done while it's plugged in and detected)

if you're able to, I'd think about taking the graphics card back and exchanging it as I doubt it's a driver problem at this point

Have you tried hooking up to another monitor/TV using HDMI, just to narrow things down?

It should just work right off the bat. You normally don't have to change anything, other than switch to the specific HDMI port on the monitor/TV.

It's integrated, part of the A6-3650.

well that complicates things a little if it is indeed faulty

just to be sure, you do have the official AMD 12.10 drivers installed and not the drivers supplied by Lenovo correct?

if not, try the official AMD driver or vice-verse

Having one of the AMD integrated GPU/CPU's myself, I literally plugged in HDMI to the motherboard (which came with an HDMI port) and away I went. If your HDMI is not functioning properly it's due to one of a few things...

1.) Something is incorrectly setup in your BIOS (as the HDMI port is provided by your motherboard. You should make sure your BIOS settings indicate the system should use the integrated graphics from the GPU/CPU)

2.) AMD drivers for your integrated GPU are not functioning properly/corrupt/etc. (Try uninstalling/reinstalling the drivers)

3.) Or it's defective.

Do you have a television you can plug into using HDMI? See how it function while connected to that. If it works fine, it's most likely an issue with your monitor. If it continues to misbehave, it is definitely your system.

I do have a TV I could plug in, but that would be a fair amount of effort lugging everything over. I'll try that if everyone's out of ideas.

Sure...however I'd want to know if it's the machine or the monitor pretty quick. Especially if I have to RMA something. I wouldn't wait too long ;) You really don't need to take "everything". The tower, the HDMI cable and the power cable for the tower and mouse/keyboard? You don't need anything else. All you really need to do is turn it on. If the TV pops on and displays, fantastic. If you want to wait for it to auto turn off the TV or go to sleep and then wake it to see if it jumps back, even better.

OK, so I observed the scanning process while the system was waking up. The monitor attempted to get a signal via HDMI, but there simply wasn't one.

It would appear it's a Windows 8 issue, as someone else is having the same issue, except only with Windows 8, and not Windows 7. I think I'll just put up with it. I'd have to spend a couple hundred dollars more to get a remotely comparable system with DVI (or buy a video card, which will probably run into a CPU bottleneck, and I'd need to spend more for a system with even a Core-i3).

if you want to connect to monitor dvi, a simple hdmi - dvi adapter/cable will work.

My HTPC (the one with the integrated graphics CPU in it) is running on Windows 8. I don't have this issue, at least not on my TV.

    • WhatsApp is getting usernames, and you can reserve your preferred one now

      By Fiza Ali · Posted

      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.
    • How do you future-proof a home or small office network?

      By sphbecker · Posted

      When I think about a network, there are really two aspects, the hardware and the wiring. So here is what I would do for both. Wiring: Use Cat6A for the patch panel, outlets, and all structured cables (cables installed in walls). Run plenty of Wireless Access Point (WAP) cables, as a general rule, assume a signal can only pass through 2-3 walls and can't pass through a floor (that is conservative, but trust me on this if you want strong WiFi)  Cat6 patch cables are fine for now if you don't plan to run 10gig, those are easy to replace later if needed. Run OS2 single-mode fiber to anywhere you think you may have a server or sub-switch. (yes, single-mode for everything on a small network, don't mess with multimode unless you have entire racks of servers and that minor module cost and power savings will matter). If you really want to future proof, also run fiber to any high density WAP locations, it is likely that WiFi 8 WAPs will push the limits of 10g. Run 6-12 pairs of single-mode fiber between your MDF and the building's MDF, even if you only need 1 or 2 pairs now, those extra pairs will pay off down the road. Hardware: (its easy to say "get all the features incase you need them", so instead of futureproofing, I am going to take approach of suggesting areas worth investing in, and areas you can save money). Don't overspend thinking you need every feature on every port. You don't need 10g on every port, you don't need PoE on every port. Don't overspend on redundancy either, unless you are ready to buy two of everything, don't waste money buying two of some things and not others. Dual power supplies are worthwhile, but probably not HA or multi-path redundancy.  Get 1 "distribution layer" switch that your router/firewall will connect to as well as all your access layer switches below. This should be a fully managed 10g+ switch with a combination of copper and SPF ports, a few 25g uplink ports are nice for this switch. Given that you said it is a small network, I suggest also using that distribution layer switch for servers and WAPs, meaning it will need PoE. Speaking of wireless, get good professional tri-band WAPs, and either turn on the band stirring options, or limit 2.4 to an IoT only SSID. This will provide a solid WiFi capable nearly everything but the highest of bandwidth clients...you could even consider skipping wiring workstations depending on usage. Access layer switch for workstations and printers can be cheaper switches, 2.5g is a good sweet spot between price and future proofing, but even 1g is fine for most individual clients (the kind that could probably be fine on WiFi). You can consider saving a little on access layer switches by only getting 1 PoE switch for whatever needs it (remember your WAPs are connecting to the distribution switch, not here), and non-PoE for your workstations, because desk phones are falling out of favor. You can also save money here by not buying managed switches if you don't need them--but really do some soul searching there, if you go this route, then anything that isn't on your workstation VLAN would either need to be connected to the distribution switch, or its own access layer switch. Also, don't feel like you need a fancy fabric stacking switches for your access layer, that is the point of the higher-end distribution layer, to remove the need for things like that at this level. Home Hardware: I'm realizing the above assumed an office setting, if this if for your house and home lab then the above still applies, but you'll probably want everything managed and PoE, just because, but you probably also don't need multiple access layer switches. If your total port count is below 24, just skip separating distribution layer and access layer and just get one nice switch with the features you want. If you are at the point of considering a 48-port switch, I would instead get a nice high-end distribution switch for things that need it, and cheaper access layer switches with specs based on the needs of connected devices. For home use, don't worry about home running every device to the main switch, there is nothing wrong with running sub-switches for your media areas and office, those essentially become your access layer, just look for sub-switches with a 10g uplink so sharing bandwidth isn't an issue. Just make sure you always connect them to your distribution/main switch, don't daisy chain, the path should never have more steps than Client>Access>Distribution>Firewall>Internet.
    • Google Meet brings Gemini note-taking to AI Pro and Ultra subscribers

      By Karthik Mudaliar · Posted

      Google Meet brings Gemini note-taking to AI Pro and Ultra subscribers by Karthik Mudaliar Google's Gemini-powered "Take notes for me" feature inside Google Meet is now available to Google AI Pro and Ultra subscribers. The features work on Google Meet for web as well as on mobile, and Google says that subscribers can use it for meetings they host in many supported languages. As the name suggests, "Take notes for me" allows Gemini to listen to a meeting, generate a summary, identify action items, and save the notes as a Google Doc in the user’s Drive. After the meeting, the organizer receives an email recap with the summary and action items, while the notes can also be attached to the related Calendar event depending on the meeting setup and sharing settings. The feature isn't automatically turned on for everyone, though. Google says that all meeting participants are notified when note-taking is turned on, and users can start it from the pencil icon in Meet or enable it for future calls through Meet’s meeting records settings. For work or school accounts, administrators can also control whether the feature is available and may require explicit participant consent for note-taking, recording, or transcription features. The feature first launched back in 2024, when it was available just for selected Workspace users. Over the years, Google added refinements and more options, including the ability to enable it when scheduling meetings via Google Calendar. Google's support docs say that the feature currently supports English, French, German, Italian, Japanese, Korean, Portuguese, and Spanish, but only one language at a time. Meetings with multiple spoken languages are not currently supported, and Google recommends using the tool for meetings between 15 minutes and eight hours. The new feature makes Google Meet closer to its rivals that have AI tools already built in. Microsoft Teams has recently started offering Copilot and intelligent recap features that summarize meetings, surface highlights, and help with follow-ups, while Zoom’s AI Companion can also generate meeting summaries from desktop and mobile meetings.

    • Microsoft finally launches WSL Containers in public preview

      By David Uzondu · Posted

      Microsoft finally launches WSL Containers in public preview by David Uzondu Microsoft has announced that WSL containers, a feature that allows developers to run Linux containers natively inside Windows without the need for Docker Desktop, is now available in public preview several weeks after Microsoft previewed it at Build 2026. To use the new container feature, you first have to install the latest pre-release version of the Windows Subsystem for Linux by running a quick update command in your terminal: wsl --update --pre-release After installing, you'd get access to the new Linux container CLI (wslc.exe) and the programmable API. Microsoft said that the CLI has a "familiar format" that matches the toolsets developers already use every day. If you know standard Docker commands, your muscle memory will translate directly to wslc.exe, which even features a built-in alias called container.exe. You can quickly run a full Ubuntu KDE desktop container by exposing ports, or pass your graphics card straight into a machine learning environment to run PyTorch workloads. Passing the --gpus all flag inside the run command instantly links your hardware. Image via Microsoft As for the API, developers can now embed Linux container operations directly inside native Windows applications without exposing the command line to users. The team integrated the API directly into MSBuild and CMake, so developers can define container steps directly in project files. Apart from bringing the CLI and API into public preview, Microsoft also said that it's working on a new default file system called virtiofs to speed up file transfer rates between Windows and Linux. Microsoft also introduced an experimental networking mode named consomme, which resolves compatibility issues with corporate VPNs by routing Linux network traffic straight through Windows. One thing to note about WSL containers is that they don't run in your standard WSL distributions; instead, every application and CLI session spawns its own lightweight Hyper-V utility VM in the background. This basically reduces the chances of one app snooping on the container of another app.
