Display Port Link Failure, Active Display Port->DVI

Q: Display Port Link Failure, Active Display Port->DVI

I have 3 monitors connected to an AMD HD5770 graphics card. Two monitors connect via HDMI, and the third through a Sapphire Active DisplayPort->DVI adaptor. Things have been working fine for years, but recently I started sleeping my computer when I am not using it during the day, as opposed to my previous habit of leaving it on all day and then shutting down at night, and a couple of days after starting this new habit, I received a 'Display Port Link Failure' message:

"The system has detected a link failure and cannot set the requested resolution and refresh rate on your DisplayPort display. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer"

Now, even upon resuming my normal habit of leaving the computer on and shutting down, the monitor will work sometimes but randomly stop other times.

How can I either fix the issues with sleep, which I would prefer since I want to save energy (a money issue rather than believing my actions make any difference to the environment), or if there is a problem somewhere, determine if it is the graphics card or the adaptor that needs replacing.?

Preferred Solution: Display Port Link Failure, Active Display Port->DVI

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Display Port Link Failure, Active Display Port->DVI

It could be the hardware is starting to give out. Not all problems are software related. Going to be hard to nail down if you don't have another cable. Could be the cable or the port.

Any way to test with a straight cable, not the adapter cable?

I'm using a Dell U3415W monitor. My video card is AMD Radeon RX480. The monitor is connected via DisplayPort to my computer. The monitor is connected via HDMI to my work laptop. When I want to switch over to HDMI, it acts as if I shut off the monitor on the Displayport shifting everything over to my secondary monitor. It causes no problem, but drives me nuts because when I switch back over to DIsplayPort, I have to move my open programs around again. Is there any simple way to make this stop? If I don't use DisplayPort, and instead use HDMI/DVI combination, the behavior described does not happen. I'm guessing that is just the way it is, but I'm hoping there is an easy way to make it stop.

Here is my situation,
I own a Lattitude E7450, and needed to connected two displays to it. I went ahead and bought the Dell E-Port Plus Advanced Port Replicator with USB 3.0, since it has 2 DVI ports on the back. It shows it is compatible with my laptop.
I set up my dock, connected my laptop, as well as both external monitors. Only one monitor shows a duplicated desktop. When I go into the display settings, I cannot see any existence of another external display being connected.
All of my drivers are up to date, restarted laptop many times. Pretty bummed out.
Anyone have any solution/knowledge to this?

As mentioned in the title I have both pieces of hardware.  I also just purchased a third Dell U2414H LCD monitor.  I am trying to connect all 3 via display port.  However it seems that all I can do is 2 monitors?  When I try to daisychain them I got 2 monitors mirroring each other and one through HDMI off the laptop.

Is this a physical limitation of the replicator?  Is there a firmware update somewhere?

A:Dell Latitude E6520 & E-Port Plus 2 - Display port issue

The E6520 comes with Intel HD Graphics 3000.  The specs for that GPU are buried in the specs for the CPU itself, but if you go to ark.intel.com and look up your CPU, then scroll down to the graphics section and verify that it shows Intel HD Graphics 3000, you'll find that that GPU only supports 2 independent displays, which is why you see mirroring.  More recent Intel GPUs do indeed support 3 displays, but no Intel GPUs to my knowledge yet support 4.
If your E6520 has the NVIDIA discrete GPU, I can't find any information on NVIDIA's site about maximum number of supported displays, but based on your experience I would assume it's 2 unless indicated otherwise.

So hello to everyone. I myself got a huge problem with my T480 and the Pro Docking Station for while now.I cannot connect any display with any cable to the display ports on the back of the dock without having my T480 completely freezing up as long as the display cable is plugged in.After removing the display cable everything goes back to normal. I already got exchanged mainboard and docking station so my only left guess is a software problem. Currently running Win10 1809 up to date with all drivers (Win and Docking station) up to date. Anyone here might be able to help me here because the phone support is out of options. Greetings,Andreas

Just purchased a new Mobo (Asus P8Z77-V Deluxe). Haven't bought the CPU. I am waithing on the new 22nm models. After taking a close look at the display outputs on the mobo I have a choice of HDMI or Display Port. None of my existing monitors have ports for that. Soooo I guess I get a new display.

What should I be looking at as far as cables and the choice between HDMI or Display Port. I am not familiar with either one. Also I am assuming the cabling is different for the two ports.

A:Display Port or HDMI

You can find adapters to allow you to use either with DVI. If your current monitor needs replacing anyway, an HDMI-native model will be cheaper than the DP version.

It can get more complicated if you have plans for multiple monitors down the road.

My PC has a 4850 Radeon ATI with 2 Dual link DVI-D outputs. I recently acquired a Del U2412 monitor, which has several different input connectors, one of which is display port. ATM, I'm using DVI-D, but am wondering if a DVD-D to Display Port adaptor will increase the performance of this monitor? Thanks, Salton

A:DVI to Display Port feasibility

msalton1, it will not improve the performance, it is used to help with multi-monitor setups. A straight Display port connection can improve bandwidth but with an adapter you gain nothing.

I upgraded my monitor to a freesync and it's all really nice, a part from one SERIOUSLY annoying problem.

I turn my monitor off as well as my system, I regularly leave my system on and my monitor off. The problem is, if i turn my system on without the monitor being on (which I like to do regularly) it doesn't think there is a monitor attached and reverts to a default resolution completely trashing my desktop icons and window sizes.

I am aware that Display Port is PnP and that the whole power off visibility thing is a known issue, but surely there is some sort of work around?

I've tried to find the default screen resolution settings in the registry but not had any luck.

Has anyone found a solution to this?

Greetings,I have a T540p laptop with an Intel HD Graphics 4600 and NVIDIA GeForce GT 730M video card.  When I plug the display port using an HDMI adapter into my TV, I get picture but no sound.  The 4600 is using drivers.  If I delete the Intel driver from the system, run the setup of the driver downloaded from Lenovo and reboot, the audio works fine.  If the cable is disconnected from the TV, the laptop is powered down, the TV is turned off, the PC screen saver turns on or any part of the A/V is disconnected, the next time it is reconnected, there is no audio again.  The playback device is the TV and all settings appear to be the same as when it was working.  Re-deleting and re-installing fixes it for one time again.   Any ideas on how to fix this as it is very annoying to have to reboot my PC every time I need to do a presentation or watch a movie?

I have been doing a lot of research but all I find is B/S like when they were invented, royalty rights, extra pins ect. but not just some basics answers to some basic questions.

I have a video card and display both with HDMI and Display Port ability.
At the present time I'm using HDMI to HDMI.

1. Can I use HDMI and Display Port using 2 cables at the same time on the same screen and is it a advantage or disadvantage?
Please explain.

2. If I just use Display Port will it work better that just HDMI?

I don't have a Display Port to Display Port cable at this time.
I will buy one if it will make things better.

I'm not having a problem at this time. I'm just trying to get the most out of my hardware.

1 monitor 1 cable

since DP and HDMI are both digital, I guess there is no advantage either way (unlike analog vs digital).

2 outputs usually means dual monitor support, although you'd have to check the manual. Dual screens is the best upgrade I've ever made, esp for my C4D work - also good for watching TV whilst surfing !

BTW although I mainly use DVI, I had to buy a HDMI lead recently to test some gear. I was surprised to see a note in the package to the effect 'warning do not hot swap this lead - power down all equipment before connecting'. Apparently there's some kinda live detecting pin that can cause probs when hot plugging.

They make a VGA to RCA cable but I don't think it will work on yours because it is a CRT screen. You may have to buy a converter , your TV will accept RCA ,Component (red/blue/green) and S-video. Component would be the best. Search YouTube for info on them.

Simple question...but I have no clue as to the answer.

I was considering getting a "display port to hdmi adapter" for the display port on my XFX Radeon HD5770. Will I be able to get audio out of this port with the conversion to hdmi?

If so what adapter would you advise me to purchase to get the best 1080p video and sound?


I have another question as well now that I thought about it.

Is it possible at this time to use an "hdmi splitter cable" on the one hdmi port on this card and successfully get a good 1080p audio/video signal to both my Tv and my monitor at the same time?

I know these splitters exits but I have yet to see any good reviews on them. Are there any out there that might allow me to accomplish this?

A:Question about the display port on the HD5770

Hi there,

As far as I know, DisplayPort is an audio/video format so I don't see why it wouldn't work. But why do you need a DisplayPort to HDMI adapter when your video card already has an HDMI output?

I have had several issues when I used my XPS 13 and output video using the display port.
1. When I used a DP to VGA converter, video cuts off after a while, and will not resume.
2. When I used a DP to HDMI converter, audio from the HDMI would cut off every ~10 minutes. Unplugging and plugging the DP, or changing the project method from windows will temporarily fix the issue, but same issue would occur repeatedly. 
The above issues seemed like the laptop cuts certain signal off after laptop not being actively used (playing videos). When I have constant mouse activity, then the above issues does not show, although screen would occasionally flicker (as  if laptop was trying to re-adjust resolution or something).

I wonder if anyone can give me some advise on possible causes? The most horrible part of these issues is that the first issue happened during my own wedding when I had my XPS13 played our wedding video.

So this is the first time this sort of thing has ever happened. When I turned on my PC today only one monitor was picking up signal. In attempt to fix this I switched the display ports from the working monitor to the non working monitor. Nothing happened so I moved the cables back, when I did that the other monitor no longer received signal. I then plugged in a hdmi cable to my monitor and still no signal. I then unplugged the power to the PC and held the on/off button for 60 seconds and re plugged the power. The monitor began receiving signal but only through hdmi and the other monitor still does not work.
I have no idea how to fix this. Any help would be appreciated.

I am reasonably OK diagnosing hardware etc but I have never really used a graphics card Display Port as the primary display port on a PC. I have 11 PCs setup in a network at work, all running Windows 7, they all work absolutely fine apart from sometimes when they go to sleep / screen turns off when not in use, I can not get the screen back on!

When this happens the screens etc go off as expected and normally, movement of the mouse or touching the keyboard will 'wake the machines up' however, sometimes the screen doesn't come back on. It remains with a 'No Signal' warning box for all inputs (DVI / HDMI and Display Port). The towers are connected via the Display Port only, anyone come across this before?

I haev another similar setup in another office, using the same / very similar HP machines which have the displayed connected via DVI and have never had the problem with those machines.

Any thoughts, ideas, information, links etc that would be useful would be appreciated before I raise this with our I.T. people (who are not very helpful sometimes, hence why I like to have an bit of an idea of the possible issue before I contact them).

I can find information from people that have asked the questions and had similar problems on other forums, just wondering if anyone had a more technical reason rather than 'it happens' haha.

Thanks in advance.

I'd look at driver updates for the graphics card(from HP first, then from the GPU manufacturer), a firmware/BIOS update for the graphics card if available from HP if it's an add-in card, or a BIOS update for the system/motherboard.
