AMD Radeon HD R9 270 2GB GDDR5 dual link DVI-D?

Analog vs Digital is one factor.

Hi, thanks for the quick response. I just need to know specifically if it's a dual link DVI or a single link DVI. The reason I need confirmation is the monitor I want to buy says specifically it must be a dual link connection rather than single link to work

thanks

Hi zontarh,

This card has got one DVI-D port and 1 HDMI port. It should run on a QHD monitor without any issues.

Thank you again for the information.

The problem is that I don't yet have the computer. I'm aware of the difference between the different variations of DVI ports but I'm unable to confirm which one is actually on this specific card. Searching the net reveals too many variations of this card so I'm unable to nail it down to the one DELL fit in the XPS8700. Was hoping somebody on here would already know this as it's so critical to some monitors.

I am also wanting to purchase a Dell XPS8700 with this graphics card from Costco.  However, their description does not say it has a DVI-D, only an HDMI which does not support the higher res monitors (2560x1440).  I would purchase immediately if I knew this was the case.  Since it is an online purchase, there is no way for me to verify if the DVI-D (which I assume the D stands for dual)  is there or not.  If the Dell monitor could verify, I would greatly appreciate it.

I have now received my XPS 8700 and can confirm the AMD Radeon HD R9 270 2GB GDDR5 has:

1 HDMI port

1 Display port

1 Dual link DVI-D

1 Dual link DIV-I

I have not yet purchased a 2560x1440 screen yet so I can only refer to what I can visually see on the graphics card related to the images posted above by SpeedStep.

DVI-D stands for DIGITAL NOT Dual Link.

4K Video cards are not standard.  2560 X 1440 is an HD TV standard not a Computer video card standard.  With SLI or crossfire High end cards and 1200w power supply

• 1920x1080 @ 60 Hz - 124.4 Mpix/s
• 2560x1440 @ 60 Hz - 221.1 Mpix/s
• 2560x1600 @ 60 Hz - 245.7 Mpix/s
• 3840x2160 @ 30 Hz - 248.8 Mpix/s

Zontarh,

Thanks for the info. The specs would work for me.  Did you purchase your XPS 8700 directly from Dell or Costco?  There are several different configurations - which did you purchase?  The Costco Dell has 24gb memory, 2T hard drive, 256gb SSD with the same graphics card you mentioned above.  I use the Adobe Photoshop, Illustrator, InDesign, Perfect Photo Suite 8.  My photos are very large so I need a high res monitor.

For the record, my iMac 27" has a 2560x1440 display (just double checked) and it is not a TV.

Hi, I purchased mine directly from Dell online but from the UK site so may have different options. Mine has 16gb ram 2gb hard drive, 32gb ssd cache and also the mentioned graphics card. I also need the monitor for photo editing hence the 2560x1440 resolution required. I think SpeedStep may have been referring to the aspect ratio regarding TVs 16:9 which is the norm but it's also becoming the norm for monitors but having said that the 2560x1440 resolution is rarely seen in a TV but plentiful in monitors.

WQHD (2560x1440) (Quad HD) also sometimes advertised as 1440p
is a display resolution of 2560x1440 pixels in a 16:9 aspect ratio.
It has four times as many pixels as the 720p HDTV video standard hence the name.

1440p is a newer resolution of high-definition television and movies, referring to the resolution of the picture itself. The number 1440 refers to the vertical resolution of the picture, indicating 1440 pixels in the vertical axis. This is understood to be combined with the standard 16:9 ratio of high-definition television, indicating a horizontal resolution of 2560. This yields an overall pixel count of 3,686,400 pixels for a television in 1440p resolution, substantially higher than the 2,073,600 pixels found on a 1080p television.

Standard DVI video output supports digital resolutions up to 1920x1080

 I don't see 1440p available for low end cards that have less than 3 Gigs of ram. (This would mean power supply upgrade as well as video card upgrade.)

WQXGA (Wide Quad Extended Graphics Array) is a resolution of 2560x1600 pixels with a 16:10 aspect ratio. The name comes from it being a wide version of QXGA and having four times as many pixels as an WXGA (1280x800) display.

To obtain a vertical refresh rate higher than 40 Hz, this resolution requires more bandwidth than a single link DVI supports and requires Dual link capable cables and devices.

Well despite the information given by speedstep I feel confident enough to buy a hi res monitor.  I don't need high refresh rates as I'm not a gamer, I just need it for editing hi res images and video editing. It would seem pointless to put a dual link port on the card if it was only able to display max 1920x1080p.

Thank you for the clarification.   So, am I correct in saying the dual link (DVI-D and DVI-I) and the displayport will support the higher resolution monitors at 60 hz (2560x1440 or 2560x1600)?

Here is photo I have just taken of the back of my XPS 8700 showing the available ports of the AMD Radeon HD R9 270 2GB GDDR5. At least now you can decide for yourself

What I am saying is DVI is limited. HDMI at the full resolution 2560x1440 or 2560x1600, you would have to make sure that both the video card and the monitor are HDMI 1.4 compliant. High Speed HDMI specification (Version 1.4) does Digital Audio and Video signals at 10.2 Gigabits per second. So you need

So you need a Achieva Shimian QH2700-IPSMS 27" LED 2560X1440 Computer Monitor or HDMI 1.4 1440P TV.

I have the same problem. I have a 30 inch dell 3007wfn monitor that has been working with my old xps 720 system which has a nvidea ge force card having dual link.

i just got the xps8700 with the amd radeon r9 270 gdd5 card. All I get is a blank display. I have contacted dell and amd and have tried everything but nothing works. I am not sure if there is a compatibility problem or a graphics card problem.

i find this very frustrating with a brand new system. We will continue on and see how this plays out!
