Dell U2713HM, use DVI or HDMI ?

The Matrix · 13 Apr 2013 at 11:05

I recieved my new Dell U2713HM earlier, i presumed it would come with a displayport cable but it seems Dell don't include one, ive got a choice between DVI and HDMI for the time being, i presume DVI would be best ? I'm using a 7970 graphics card.

What res will DVI give you, can you get 2560 x 1440 on DVI ? I take it in the long run that displayport will be best to use ?

Dual Link DVI is required for anything over 1920x1200 if I'm correct?

Not 100% though.

EDIT: I imagine that the cable supplied is a DVI, be careful plugging it into your GPU as there are a few different pin layouts for DVI and you don't want to break your GPU connector.

Correct he would need to use DVI to get 2560 x 1440 or display port if he had the cable available

My Sapphire 7970 Vapor-X has 2 DVI connections, one white and one black. I connected it to the white one as the included DVI connector is white, i just presume with them being colour coded that you connect it to the relevant coloured one. I presume the other black DVI connector is for dual link DVI ?

The monitor is up and running, not had a chance to do much with it yet but my early impressions are its a very sleek looking, great monitor. Can't spot any obvious light bleed but i'll test that tonight in a dark room, no obvious dead pixels. The Dell packing is great as well, the monitor is very well protected, i like the stand design how its so easy just to clip it onto the back.

Really impressed with it, Overclockers were superb as well in sorting out a good deal for me and getting the monitor delivered today saturday.

you need to use dual link dvi or display port to support 1440p

if you look at the dvi cable

you should have 4 pins + - then loads of pins with no gaps

I don't have one of those cables at the min, they are not included with the monitor, i was presuming they would be otherwise i'd have ordered one with the monitor.

The Dell display manager is saying its displaying 2560x1440

smogsy · 13 Apr 2013 at 12:09

thats interesting, maybe its 1600p im thinking of, i knoe 1600 requires dual link or you get 1920x1080..
looks like your set

Thanks for the link, ive just checked the DVI cable, its dual link..... I feel a bit of a lemon now lol

The bit that threw me is on the Dell site in the listed accessories that are included it just says DVI cable, doesn't mention dual link at all.

Is their any real difference between displayport and dual link DVI other than its easier to plug and unlug a displayport cable ? If their is no real difference i'll leave it on the dual link DVI cable as it seems to be fine.

Stick with the DVI tbh, probably not worth the hassle.

smogsy · 13 Apr 2013 at 14:24

no difference only real difference is

dp supports 30m + and has usb/power built in which no one uses yet from my knowledge

The monitor is going back, ive tested it out on some movies and web browsing and its got a horrible big light bleed in the bottom left hand corner, it goes brighter when you launch something like a browser, the same when watching a movie as it goes dimmer and brighter depending what the scene is and how much brightness it needs.

I'm more suprised Dell send this kind of stuff out especially given the price, does quality control not exist these days lol...

Dell have an outstanding warranty on there panels, I'm sure if you inform them they will have a new one with you by Monday.

PCM2 · 13 Apr 2013 at 16:09

As above, try for a replacement. Backlight bleed varies between units. Some of this can be caused by pressures placed on the panel itself during manufacture (LG's fault), some when everything is sandwiched together (by Dell) and also during transport and storage. And it sounds like you had either 'Dynamic Contrast' or 'Energy Smart' enabled. 'Dynamic Contrast' is enabled on certain presets by default (such as 'Game').

Its a common probblem apparently from what i read on the net before buying one, it seems to be pot luck if you get a good one without light bleed or the other reported issues, obviously i was hoping it would be a good one and i think this was new stock at Overclockers as they were out of stock the week before i bought it then 4 came into stock. Obviously the issues are still here even with new stock.

A new one by monday, i'd very much doubt that, i'd have to go through overclockers anyway.

Dynamic contrast is off, its one of the first things i turned off, i also turned the brightness and contrast down. A few examples

Not sure why you didn't buy direct from Dell? Thought it was well known their warranty with the high end panels is outstanding.

Have you seen the price on the Dell site ? Its £626 on the Dell site and for the same Monitor at Overclockers which has come direct from Dell its £439, also included when you buy from Overclockers is the Dell Warranty: 3 Years On-Site (Premium Panel Guarantee).

If it includes the 3 Years cover then you shouldn't need to go through OcUK.

Rusty0611 · 13 Apr 2013 at 16:44

Just go through Dell. I did for a small patch of bright pixels (same monitor) and I had a brand new replacement within 2 days.
