Connection Types There are currently four common ways to connect displays to video cards. Depending on what ports your video card has and what inputs your monitor has, choose whichever one you have available or will work the best for your needs. VGA (video graphics array) has been around the longest. VGA is an analog signal, meaning the quality may not be ...

Yes, the DisplayPort spec is an audio/video interconnect spec. It can carry both audio and video over a single connection. It is rare a laptop implements audio-out over a digital video interconnect. My MacBook Pros don't do it over their DisplayPort outputs, that's for sure.

The nice thing about Digital (HDMI and DVI) is that it is noise tolerant. On an analog line, to get a perfect picture the voltage at the receiver would need to match the voltage at the sender. Noise can get in there and distort the signal. On a digital line, the receiver simply needs to determine if the signal is a 1 or a 0 (high voltage or low voltage). ...

Connect a DisplayPort display to Thunderbolt port As Apple says on their Thunderbolt product page: And because Thunderbolt is based on DisplayPort technology, the video standard for high-resolution displays, any Mini DisplayPort display plugs right into the Thunderbolt port. To connect a DisplayPort, DVI, HDMI, or VGA display, just use an existing ...

If your monitor has a 'source' button on it (they often look like this), that should switch between the various inputs. Otherwise, you can get a KVM Switch to change over the keyboard, mouse and monitor between computers all at once (There are probably variants that only change the monitor as well).

Don't forget that HDMI and DVI support HDCP, or high definition content protection. It's a kind of DRM that prevents you from playing your HD content at full resolution. When buying these cables, be sure that they support the HDCP. Then again, you can always go with the analog hole... Also, remember that DVI single link and double link differ in the amount ...

For your use there is no special advantage to DisplayPort, and in some future where all video cards use DisplayPort, there is an easy adapter for DisplayPort->DVI so your monitor won't be obsolete. The only advantage DisplayPort would give you right now where if you where running a 30" or other very high resolution panel, where you could use a single ...

The DisplayPort Spec supports the daisy chaining of multiple monitors, but not the splitting of the signal. Unfortunate, to support this you need to have at least 2 DisplayPort equipped monitors that support daisy chaining (of which there are none to my knowledge). Given your situation, your best bet would be something like the Matrox TripleHead ToGo, ...

Looks like displayport - its pretty common on desktops and quite a few laptops

I also have Lenovo Thinkpad T410. Once you have a video playing, go to Control Panel, Sounds, Manage Audio Devices. When you're in Manage Audio Devices, you'll see a list of devices and your TV speakers should be one of the options. Just choose it and set it as your default audio device and the sound should automatically come on the TV.

HDMI and DVI are the same as far as video is concerned. You can switch between them with a $2 adapter. Both of these are digital formats. VGA and component are analog formats. While this is fine for driving a CRT, there is a definite quality loss when connecting to an LCD, since there is a conversion from digital in the video card to analog on the cable, ...

From what I heard, the cheap adapters don't work because you need something that generates an TDMS Signal. The cheap adapters expect the source to already support a TDMS Signal and more or less just convert mechanically. I have a post here. I ended up buying a $100 Dell Adapter which works, but fails whenever power savings comes into play (I basically have ...

I'm going to add extra information about Display port, especially considering the fact that AMD's Eyefinity puts this technology front and center. Eyefinity It basically takes one desktop and scales it to multiple screens. So if the 3x1 Landscape on the top left is three 1920 monitors, then it would show a single Windows desktop with a resolution of ...

I have the Surface Pro and I've it connected to dual monitor with the Zotac DisplayPort. It works perfectly with a resolution of 3840x1080 and apart the surface screen.

DisplayPort acts as a PNP device, so turning off the monitor disconnects it from the computer as if it was removed and windows are moved out because Windows forgets this device, until it is turned on again and is "discovered". One solution is to just let the screen go into sleep instead of turning it off. There are ways of programmatically forcing that, for ...

Of course it can. The feature is called USB over AUX, since the DisplayPort v1.2 Standard specifies this in its Link Layer. You'll find information in the DisplayPort 1.2 press release: Another new feature is the ability to support high-speed, bi-directional data transfer, allowing USB 2.0 or Ethernet data to be carried within a standard DisplayPort ...

The type of noise you're getting is consistent with analog noise. Analog noise can be introduced from poor grounding, poor wires, and poorly grounded wiring, poor connections, or a Ground loop1. Ground loops can often be resolved by getting AC wall power from the same place at the same distance. The noise could be coming from any interference from another ...

I would agree with MicTech and add one thing... That DisplayPort is not some "proprietary system" it is a standard. A standard that is only used by a couple of companies but a standard none the less. I have several DisplayPort items and have had no problems with them thus far. UPDATE: As far as inexpensive cards... I found this ATI one on Newegg. No ...

Yeah, the way the Radeon hardware works, is that one display circuitry drives both the DVI2 and the HDMI port. So you can't have them both hooked up at the same time. Therefore to get 3 monitors, you have to do DVI+DVI+DisplayPort, or DVI+HDMI+DisplayPort. DVI+DVI+HDMI is unfortunately NOT an option. I believe the DisplayPort to VGA adaptors for ~$20 should ...

If you can live with 1920x1200 resolution: HDMI to DVI Cables for $20+ DisplayPort to DVI Cable for $30+ If you want 2560x1600, you need an active adapter.

Dell now offers (at least) two monitors with DisplayPort 1.2 ports for daisy-chaining: Dell U2713H 27" Monitor Dell UltraSharp u2913WM 29" Ultra-wide monitor I cannot, however, confirm that they work with the MacBook Pros. If/when these ports start showing up on their lower-end monitors I might take the plunge.

This is how it's designed to work (or at least it's been this way on all the Windows 7 machines I've used). When you first turn on the machine or lock it only the primary monitor is active.

I finally called Apple Tech. Support today and spoke with a tech. on this issue. It is a known issue that is scheduled to be addressed by Apple in a future update. He said there is no workaround currently other than to erase and install back to 10.5. Sorry to be the bearer of bad news, but that's what I was told.

It's largely an issue of what your input and output devices support. For example, I have a dual-DVI video card, and an HDMI HDTV (via receiver), and DVI-capable monitor. So I have a DVI->HDMI cable for the TV and DVI to the monitor. HDMI, as it can pass audio, lets you consolidate cable clutter if your PC has HDMI-capable sound output. Laptops with HDMI out ...

Disable the "DisplayData Channel Command Interface" (DDC/CI) in your monitor settings. As a result Windows will not recognize if you turn off your monitor and your desktop icons stay as they should. I successfully tested this on a Dell monitor! Wikipedia descripes DDC/CI as follows. I'll just leave it at that. There isn't much about it on the net. ...

Surface Pro 2 ships with either i5-4200U or i5-4300U CPU, both Haswell chips with HD Graphics 4400 GPU. According to Intel, these chips have 4th generation graphics (HD Graphics 4200 and up is 4th, 4000 and 2500 is 3rd) and thus support DisplayPort 1.2. Apart from graphics adapter support, you will need compatible monitors. These monitors should be ...

If the Wikipedia article is to be believed (and I do believe it is correct based on what thunderbolt is), then your configuration will not work. Compatability Apple Thunderbolt Displays, like the video input on Thunderbolt iMacs, drop compatibility with all previous standards, including VGA, DVI, and DisplayPort.[3] As such, they cannot be ...

There is probably no advantage. Both are digital formats and there should be no image quality difference between those two. The only reason two switch are: If you have a monitor with speakers and you are now using both a DVI cable and an audio cable. (thus using less cables) If you have multiple display port monitors and you want to chain them, so you use ...

This doesn't work - Ivy Bridge processors only support DisplayPort 1.1, so no daisy-chaining. (Haswell does, though, so likely the next iteration of Surface will support this).

I asked a Startech rep: Just wondering if I can get a bit of product clarification. I'm looking at the MDP2DPDVHD "Mini DisplayPort to DisplayPort / DVI / HDMI Multifunction Adapter". I'm wondering if it supports multiple monitors simultaneously, or if it's just a converter for one monitor per adapter? His reply: This is only going to support 1 ...
