Hi I am wondering if it is possible to run two monitors from the GPU and CPU. I tried running them both on my graphics card but it never worked. It only seems to work with one. I read that one of the ports only has enough power for one?

So I thought maybe I could run one of the CPU and the other on the GPU? My motherboard has a Monitor output but is it possible to enable them both in the bios? Or can it only run either the gpu or the cpu gfx at one time (the i7 3770K has onboard graphics)? I can only see the ATI in the device manager but if I take the graphics card out the onboard one is displayed after rebooting (to be expected).

If this is not possible I will probably just buy an extra graphics card. All specs in my sig.

Edit, I run windows 8 pro (I actually like it so don't go of topic about that)

I said my specs are in the sig, and I said it didn't work when it had two monitors in the GPU. Did you read my OP?

Erm, of course I read it, I don't have sigs enabled though, so list your specs

And explain what you did when you failed to enable 2 displays

To answer your question no, once a PCI-E graphcis card is plugged in the onboard graphics (be that old school intel mobo grapics or new schoole CPU integrated graphics) are disabled.

However there is no way your GPU can't power 2 monitors itself...as mentioned it should be able to do 4.

You must have a setting mis-configured. or old drivers....that or your card is faulty...in which case send it back.

Just about every modern GPU can run 2 displays natively, for 3 you might need to connect to a display port if using just 1 GPU, but for 2, simple job of connecting and enabling

Exactly, I think even my GPU from about 2003 could do dual screen.

but yes if you want 3+ monitors you'll need either dual cards or eyefinity with display ports.

My specs are:

PC: Intel Core i7 3770K Quad Core IvyBridge, Asus P8Z77-V LK, 8GB DDR3, ATI Radeon R6950.

I don't recall it appearing in the display propties as two monitors when they both are on the GPU. But I will try again.

Are you perhaps using a DVI to VGA cable on one or both monitors?

The AMD Radeon 6950 has 2 DVI connectors at the back, but one is DVI-I and the other DVI-D. The DVI-I connector has both a digital and an analog signal, which means only the DVI-I-connector can use a DVI-to-VGA cable.

So you need at least 1 monitor that has a DVI, HDMI or DisplayPort connection, if the other monitor only has VGA

Ok, so what are the 2 connections from the GPU to the displays ?

DVI / HDMI or DVI / DVI etc etc

What cables are you using ?

If both displays using either of the above ports are connected and turned on, then Windows should see them in display properties shown in my screenshot

EDIT - And what are the 2 display models ?

Yes you should be able to, I'm running 4 monitors off my graphics card and a 5th off the onboard graphics with no problems, just enabled it in the bios and windows picked it up.

Thanks for the replies so far.

My main monitor is a DellST2410 that is hooked up on DVI on the first availble DVI port.

The second monitor is just an old videoseven VGA widscreen using an adapter to DVI, I know it's not the greatest make compared to my dell but thought it would make good use for a second monitor (so I can have other stuff open while I am playing games on my main monitor).

It does actually now apper in display properties but won't let me enable it.

So try switching the cables around, also make sure you reboot after swapping them around. Windows doesn't always allow you to configure your monitors properly if they weren't connected during boot, not sure if this changed with Windows 8.

This ^^

DVI-I should be the one connected to your VGA display as it can carry analogue signals

DVI-D can only carry digital

VGA is analogue

Yer I just tried switching them around. The second monitor did detect in Windows but it did not output anything (I set the correct resolution and extended the displays) but nothing however it was listed in device manager. Just kept getting no signal detected.

Are you sure the cable you are using for the VGA display is DVI-I ?

You're not plugging your monitor into your CPU. Your motherboard has an onboard GPU. Thus you have two separate GPUs.

Is your monitor powered on? Have you tried another monitor? or tried that monitor on another computer?

I was under the impression the CPU had an on-die GPU, http://www.anandtech.com/show/5771/the-intel-ivy-bridge-core-i7-3770k-review/8 and the motherboard port was just to connect the display to it.

Yes the monitor is on, not tried another monitor but will try it on another PC to make sure it's working.

I've had the onboard (i7) graphics and an add on gpu (560GTX) both working concurrently - I wanted to use the onbooard for mornal, unintensive windowsie stuff on one screen, and the higher stress stuff (gaming, etc) on the GPU.

It did work, but actually it caused my media center playback to stutter, even on the other screen. Went back to running them both off the graphics card and it works so so so much better. Onboard has been disabled again.

(as a note, I also have sig's hidden, as I suspect many here do, so was unable to see your specs)

Yeah you're right. I forgot new CPUs have integrated GPUs. It just sounds weird.

    • 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 10g switch with a combination of copper and SPF ports and should be a fully managed 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 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. 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.
    • 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.
