Agree need dual link to achieve max resolution, but I would have thought I could run at 1600x1200 with a single link DVI ouput. It seems not.
I would have thought that it would work with DVI-D or DVI-I (both single link). A key point however is that it has 2 DVI inputs so maybe it is set up only to work with 2 inputs. The DVI connector on a device is therefore given one of three names, depending on which signals it implements: DVI-D (digital only, single-link or dual-link) DVI-A (analog only) DVI-I (integrated, combines digital and analog in the same connector; digital may be single- or dual-link) The DVI-D and DVI-I connector provide (via additional pins) for a second data link. This allows resolutions up to 2560x1600, which are supported by many add-on graphic cards. A connector with these additional pins is sometimes referred to as DVI-DL (dual link). The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so it is not possible to connect a male DVI-I to a female DVI-D by removing the 4 analog pins. It is possible, however, to connect a male DVI-D cable to a female DVI-I connector. Many flat panel LCD monitors have only the DVI-D connection so that a DVI-D male to DVI-D male cable will suffice when connecting the monitor to a computer's DVI-I female connector. http://en.wikipedia.org/wiki/File:DVI_Connector_Types.svg
a better question, what does your card support? can you run a monitor with less of its res? yes as long as that monitor has the right connector... which it seems it has a variety...assuming you do have the U3011... then this is what you have.. 2 High Definition Multimedia Interface (HDMI) 2 Digital Visual Interface connectors (DVI-D) with HDCP 1 DisplayPort (DP) 1 Video Graphics Array (VGA) you know you can always downgrade the res on the DP right?
Power consumption off 30´´ DELL monitor 147W to 177W (max). So it is better to opt for the 24´´ DELL monitor, 16:10, 1920x1200. average power consumption 25-30W. This is the monitor for traders! I´am using 3 LG TN Panels 16:10, resolution 1680x1050. This panels are about 5 years old and still excellent for my trading. I trade 3 markets so one monitor each monitor is chowing 3 charts from one markets. And then I have one extra monitor an old LG TN panel resolution 1280x1024 as my distraction monitor where I have mail open and exel spreadsheet to control positions. Thats it. Keep it simple! I´am thinking off buying the above 24´´ monitors from DELL but I think I only will gain in therms of quality so for now I will stick to my setup. I have traded 4 markets at a time but I skipped one market because it was too much too look at and ended up missing trades. So too much is not always good.
3x 24" (Dell 2407's) No room on the desk for bigger - surrounded by book cases. Love the setup ! Charts on left, watchlist on right and browser in the middle.
30Hz 3840 x 2160 television prices have dropped in recent months: Seiki se50uy04: 50", ~$1100 at Amazon Seiki se39uy04: 39", ~$700 at Amazon and Sears Skyworth: 50", reportedly ~$1500, reportedly supports 3D, maybe only sold in China Skyworth 39e780u: 39", reportedly ~$600, maybe only sold in China Tcl: ? Be warned that the 50" Seiki is reported to have horrible overscan when run at 1920x1080, so it seems you really have to stick with 3840x2160 @ 30Hz only for that display. It may be that all of the above televisions share this problem and are being sold off so cheaply for that reason. In comparison, the Asus pq321q: 31.5" monitor (not a television), which can do 3840x2160 @ 60Hz through DisplayPort 1.1 dual mode, costs ~$3500 at Amazon. I expect that refreshing at 30Hz instead of 60Hz would delay display by an average of by ~8.333 milliseconds (1 second/30/2 - 1 second/60/2).
I have a few updates to my post about 3840x2160 @ 30Hz displays. 1. Tcl le50uhde5691 (50") is now being sold for ~$910 at Amazon. 2. I'm not completely clear on this, but I get the impression that firmware updates for the Seiki displays available at http://www.seiki.com/support/downloads.php#firmware might result in 1920x1080 @ 120Hz aligning properly. 3. HDMI 2.0 was finalized a few months ago. So, I hope we'll soon have similar displays at similar price points that add support 3840x2160 @ 60Hz, either through HDMI 2.0 or DisplayPort 1.2.
As an update to my original post, I decided not to use three 30 inch displays, even though I did buy a third. I've changed tracks a little, and added some little monitors to my setup now. We'll see what I do in the end, but my pc can run up to 18 monitors, so no limitation on video outputs.
