HDMI and DisplayPort are capable of transmitting audio as well as video. So, to Windows, it looks like an additional soundcard appears on your system, for which a driver is needed. So if you connect a monitor on the other end of your HDMI or DisplayPort and it can play sound, you can send sound to that monitor by selecting "Intel Display Audio" or ...

It's for sending audio through the video adapter, for use with video interfaces that support it (like HDMI and DisplayPort).

You are right: HDMI, DP and DVI-D use digital signals, while VGA uses analog signals. You'll need to buy adapters that convert those digital inputs to analog outputs (so yeah, no "passive" adapters). VGA degrades quality quickly with bad/long cables as well as with high resolution displays (it'll need to send analog signals, changing the output voltage at ...

You need a card with two DisplayPort 1.2 outputs. DVI connections are not used by this monitor. Edit: this monitor connects with two DP cables and each cable appears as a single logical screen (there is no MST involved). So there is no requirement for the card to support more than two logical screens (which can be problematic for some Nvidia cards). Any ...

Technical previews are not designed for end users, it is for software designers (like the people who write those drivers). That way when Windows 10 has its general release drivers will be available day one. The only solution is time. All you can do is wait for Nvidia to release a driver (keep a eye on their Beta drivers, it will be there first).

In general that is correct, RAM is mostly used for systems processes and is where your running programs store most of their information and use the most memory. For instance, if you look at the memory usage of something like Firefox, most of your memory usage is going to be your RAM. VRAM is used specifically for calls made to the video card through a ...

I ran into this problem on Windows 7 with an AMD card. I don't know what that key combination is supposed to do, but it seems to switch to 256 colors and 640x480 resolution. Correcting the resolution/bit depth To fix the problem, you need to return to normal resolution (and bit depth). You can do this with either the Windows "Screen Resolution" menu or in ...

The screen-size on the Yoga 2 laptop is much larger. Dxdiag shows : Display Mode: 3200 x 1800 (32 bit) (60Hz). As per your tests the Yoga 2 is blazingly fast when using the same resolutions, this is probably a hardware limitation on the performance of the embedded Intel HD Graphics 4400 card. Embedded video controllers are usually much slower than ...

The point of the 2 is to enable your laptop to use a lower battery consumption when you don't need the power of a high-spec GPU. Most of the things you do on the laptop probably don't need high-spec graphics. There should be an application running that associates applications with each graphics card. So if you are not bothered about battery life, simply ...

Context is everything, but in general computer terms, video cards and graphics cards are the same thing. There are "video capture cards," which are often called "TV tuner cards" or "video encoder cards" that capture video (instead of outputting it). These would be used to record video such as TV shows, or get video from an old camcorder, or other playback ...

With older systems, the 'onboard' graphics was a distinct chip on the motherboard. With modern intel systems, from sandy bridge onwards, its part of the CPU. The chipset that the video adaptor was part of has been merged into the CPU proper. The mainstream processors the z97 is designed for have GPUs built in. The server chips do not, and the onboard ...

Is it possible that the card has been destroyed somehow without functioning fans? Yes. Excessive heat reduces component life. Some of the parts have thermal safeties, but many of them don't. Why would losing power have been the point at which the card stopped working? There are three possible reasons. One is just coincidence. Another is that ...

Clearing Up Misconceptions linux doesn't support Nvidia drivers out of the box because of legal issues While this is technically true for completely separate reasons, Ubuntu (which is not just Linux; it is Linux plus a great many other (separate) things clobbered together) does ship the proprietary Nvidia and AMD graphics drivers as a default part of ...

Disabling the ATI/AMD kernel extensions will not force the OS to switch to the Intel integrated graphics. It's a misconception in all the fixes/instructions out there... All that does is running the discrete chip with a fallback driver with no graphic acceleration. This is akin to seeing the "640x480 VGA" standard display mode on Windows back in the day ...

Over the years the discrete graphics adapter market has adopted a tiered system to sell as many SKUs per GPU as possible. In general, although some OEMs and processes may differ slightly, here is how the third-party graphics adapter market works. A GPU designer/manufacturer (AMD/NVIDIA) designs a chip, tests it, and then mass produces it in an external ...

Some display interfaces, like HDMI and DisplayPort, can carry audio along with video. This audio stream might get played back by your monitor's internal speakers or you might send it to a dedicated "audio receiver", that strips off the audio signal, sends it out via e. g. S/PDIF, analog RCA or even digital (AES/EBU) or analog XLR. In fact, both HDMI and ...

The Radeon R5 230 is a rebranded Radeon HD 6450. They use the same underlying GPU and differ only by memory speed. The Radeon HD 6450 uses a TeraScale 2 (VLIW5) architecture "Caicos" GPU with 160 shader cores operating at 625 MHz. Memory is 512 MB to 1 GB of either DDR3 or GDDR5 at up to 900 MHz. Specifications: Wikipedia, AMD. The Radeon R5 230 has the ...

Your hard drive is failing and should be replaced as soon as possible. When your hard drive encounters bad sectors, it moves the data located there to a special spare area in a process called sector reallocation. The presence of bad sectors on a hard drive indicates degrading disk media, which can eventually lead to drive failure. A hard drive undergoing ...

Go with the 750 watt power supply. It will be able to handle your system. I had a 500 watt power supply before and had issues with the computer shutting down due to high load from the graphics card when I upgraded to an i7 CPU and 970GTX graphics card.

The AMD proprietary driver is good only for 3D rendering. When it comes to 2D, the overall performance is quite poor. However, if you install the open source driver, it is the opposite: 2D is far better, 3D performance are a mess.

Knowing laptop hardware in general, it's highly unlikely that you would be able to upgrade a the graphics card in that laptop. Since the laptop is so new, I couldn't find any disassembly guides for it, but I can say with certainty that the level of disassembly required to replace a laptop GPU will void your warranty and won't be cost or time-effective. You ...

You need to have two DisplayPort 1.2 connections in order to run at 5120x2880 with 60Hz refresh rate. A GeForce GTX 960 is currently the cheapest way to get proper support for 5K on this Dell monitor. As mentioned, as long as you only want to use it for everyday work (CUDA acceleration in certain Adobe applications such as After Effects or Premiere may ...

It could be that software changes (additions of background programs that use lots of RAM or CPU; new drivers with performance regressions; etc) could be part of the reason. However, because this is such a vague question with so little information, it's impossible for us to guess at any specific reason why it might be so. However, I can immediately point out ...

Are you sure that your system goes haywire at GPU's temperature going over 65°C? Because in my opinion, 65°C is not hot. Hot is when GPU reaches 80-90°C. Even then it works. I believe the problem is somewhere else. Just to be sure, blow any dirt off of the heat sink. If you feel comfortable you could remove the heat sink and replace the thermal paste. Then ...

I'm an idiot and not plugging things into the graphics card does indeed mean it's not being used. Solution: go buy another HDMI cable. UPDATE: Bought an HDMI to DVI cable and graphics card is now under load when playing games, and can run Mirror's Edge at max settings with no noticeable frame issues. Not much of a claim to fame but it's the only thing I ...

This looks like a power supply "problem". It seems your old card - the Nvidia GT 620 - has a power draw of up to 49W. Few PCs have a power draw of significantly more than 100W, without GPU. A standard 200W power supply covers this easily. I can't manage to find the exact spec for your new card, the AMD R7 260x, but from what I can find it clearly has a much ...

There's four main reason for them, the benefits of each are debatable: Aesthetics, some people prefer the look to a bare PCB Rigidity, depending on how it's constructed it can help larger/heavier cards "drooping" once they are installed in a case; potentially reducing stress on the PCIe slot. Cooling/Heat dissipation, arguably the metal can help dissipate ...

First of all, it's hard to give a clean-cut answer when we don't know what outputs your laptop has, and what inputs your monitors have. If your laptop has a DisplayPort 1.2 output, you can daisy-chain two monitors through it. So yes, it's possible. Your graphics card surely has the muscles to run two full-HD monitors, provided your laptop can provide output ...

With newer model Motherboards, such as the Z77-G45 Gaming board, you can enable a setting called IGD Multi-Monitor. This allows you to use your Motherboards specific display driver as an active display, alongside your Graphics Card. If you pin through your Motherboard BIOS settings, and search for this option, you should be able to accomplish this task. ...
