DELL XPS 2710 AiO - HDMI in

dennis.vetter,

HDMI is a video mode and can only do 1920x1080p.

1. If this is Dell's product policy - why is the HDMI-out port supporting higher resolutions than 1920x1080?

2. Why is there no other input option supporting the native resolution of the display? (DP, DVI)

3. HDMI specifications 1.3 and later officially allow higher resolutions than 1080p - even as a video mode (1440p, 2160p).

I actually found a solution for my problem which is called "Downsampling" to create a custom resolution like 2560x1440 35Hz under Windows. This also works with most Dell monitors and the HDMI input problem. You need a HDMI 1.3 or 1.4 compatible graphics output and a HDMI high speed cable with the same specifications.

Hi Dennis

Your downsampling - what is the dispay quality like?  This is the only thing stopping me from buying an XPS-27 and I can't find the answers anywhere either!

Is 2560x1440 on a windows desktop acceptable?  I have another PC I want to use as an input to the XPS.  I can't understand why the HDMI-In only supports 1080p - this is now terribly outdated! 

Thanks

John

Hi John

the picture quality is ok. The panel still runs at 60Hz even if you input at 35 Hz. (as far as i know)

No one understands why there is no support for the native resolution.

I'm running the display out of regular specifications and therefore I can not recomment you to buy this product.

I just tried the above and got an ok at best picture.

After fiddling a bit more with the timings I used something called CVT reduced bank and got the same fabulous picture from me input computer that the XPS has natively.

I'm running an NVIDIA GTX 260 card on my input systems.  The follow is the custom resolution I created with the NVIDIA tools.

Was this ever resolved? I started a similar thread whereby I ask Dell Support if I could use the xps display at its native resolution when using my works laptop as an input. They told me that yes I could (via hdmi) and that touch would also work.  Based on this thread, it sounds like it may not be true. This is stopping me purchase this computer until I can find out a definitive answer!

Thanks Dan, your post will single handedly enable me to go ahead with the purchase. Just to avoid any doubt, can you confirm that you're talking about using the xps one as an external monitor with a laptop as the source? One additional question - were you able to utilise the touch functionality with this set up? (My works laptop won't have windows 8)

Thanks again for your reply! :-)

Gladly Ender4000,

I'm using the XPS One 2710.  This model is not touch enabled so I can't help with that part of your question.

I use it as an external monitor for multiple systems.  I plug a laptop and desktop into an HDMI switch box and the box into the XPS.  I'm using the custom resolution settings only for the desktop system.  The laptop displays on the XPS in standard 1920X1080 at 59 Hz as second monitor and the desktop is displaying in 2560 X 1440 as the main monitor of two for the desktop.

There is a control on the face of the XPS that selects the input between the XPS computer and the HDMI external source.  However most of the time I use VNC to remote desktop and see what the XPS computer is doing. It's just faster.
