DP->HDMI adapters are uni-directional, you can't convert an HDMI to a DP signal with that particular adapter. You need something like this: http://ca.startech.com/ppc?product_id=HDMI2DP&gclid=CjwKEAiAk8qkBRDOqYediILQ5BMSJAB40A5U0c0lj_TCNo7Rs6fVZhBnIP9lRqH2lrEizwNYHjPriBoCPlHw_wcB but it isn't...

2711 doesn't support 2560x1440@60hz over HDMI. Not an issue with HDMI, it's something to do with the monitor itself.

You don't need active DP -> HDMI adapters for this. Passive adapters will work for this application. Tape is your best friend in this case. Can't help you with the monitors lighting up the room while gaming, either stick with DisplayPort and put up with your icons moving around, or switch to...

If turning off the monitor messes up your desktop, then don't turn it off. Is there a specific reason why you need to turn off your monitor? Most monitors will go to sleep and consume very little electricity even if you don't turn it off. DisplayPort is unfortunately the cause (you can switch...

Aftermarket upgrades for laptop processors are not recommended. Buy the processor you need at the onset. Also, there's no way you can get anywhere close to the same performance as a desktop i5-4670k, even without overclock. The x240 is limited by voltage, by heat, and by power. The fastest...

Good start... Ok... Uh oh... Definitely not. Good luck. Other than the 3D compatible (no overclock will allow for 3D compatibility), You just ruled out the only monitors in existance that do anything close to what you want. Try this screen for a non-IPS version.

I have not seen a single hardware converter (that is not itself an independent computer) that can do it. I've looked and looked and never found one, not even a theoretical one. Dual link DVI signals are needlessly complicated due to how the spec requires the signal to be split. I suspect a lot...

Um... I did not say HDMI cannot be converted to SL-DVI. While dual link DVI may be *electrically* compatible (it is, after all, literally 2 DVI-D links in a single cable) with 2 SL-DVI, logically, a computer does not treat DL-DVI signals like that. DL-DVI signals are assymetric and do not...

But SL-DVI cannot, and HDMI can only be converted to SL-DVI. You may be able to drive 1440p off HDMI natively with the right monitor (don't ask me which ones do, most don't atm) or you might be able to do it at <60hz, perhaps 30hz.

Because you said the following... You did not mention that you were frustrated that you couldn't set up a high-res dual monitor display with a Thinkpad without a dock. You just raged against a useful legacy port (which is probably currently used in more monitors/projectors than DVI, HDMI and DP...

How is the removal of VGA a positive thing, given the amount of legacy hardware floating around? Among all the dozen or so people I know using Thinkpads with external monitors, 100% (one hundred percent of them) use external monitors and projectors via VGA. One. Hundred. Percent. I'm trying to...

Have you tested the display rate?

It would be very tricky to get on to a plane. It's larger than what is allowed normally for carryons, as the box is 65cm x 45cm, although it is only ~12cm thick. The thinness is there, but the box itself is noticeably large. It *looks* big from any angle except edge on.

I'm going to have to second the amazingness of the x220/x230 form factor. It's a great little machine. I run an x220. I wouldn't worry too much about the keyboard change between the x220/x230, as they're both good keyboards (workplace has a couple of t430 and t530, I set up both and was...

No current model laptops run 1920x1200 natively.

Hardware adjustments allow for more flexibility and gets you a higher quality calibration than software alone, even if you don't have access to the hardware LUT's. But more importantly... I'm among the group of people who would love to use their awesome 1440p monitor with more than 1 computer...

I did not test with an X230t, but I do have access to T430 and T530, and both of them can drive 2x external monitors without turning off the internal display.

Don't get Lenovo's consumer line for business.

10-19-2010 10-19-2010 Let it die.

Lenovo still offers Windows 7 on their Thinkpad line as well.

The manufacturer might not have validated the laptop at 16 GB. In which case, 16 GB might work, but if something goes wrong, the manufacturer isn't obligated to help you with it.

As per Asus' website: As far as HDMI and DVI compatibility, HDMI is indeed compatible with single link DVI, and only single link DVI. It is electrically incompatible with Dual link DVI.

For what it's worth, your DVI-D port on the back of the motherboard is not a dual link DVI port, which is what you needed. Haswell is capable of 2560x1440p... over DisplayPort.

EDIT: No idea where I got that idea from.

I'm guessing no budget for a MBA 13"? Those have battery life out the wazoo.

The chart is just plain wrong. Ignore it. You will be able to run it.

I have a tempered glass screen next to a glossy next to an AG screen. The U2312hm is the one I find most pleasing to the eye. The other two I use primarily because it looks cool (tempered glass Catleap), 1440p resolution (Catleap + Qnix) and overclockability (Catleap + Qnix).

Edit - never mind

It's not worth it.

It's a real overclockable one. This coming from a skeptic. Who now owns both a Catleap "2B" and a QNIX.

That depends. If my Thinkpad were my only machine, then yes, the mSATA route makes a lot of sense, especially if you store a lot of media (movies, games, video, pictures, music) on your laptop. On the other hand, I use my x220 as an ultraportable, and I don't store movies, games, videos, or...

What do you need to turn off the monitor for?

It's been verified that this monitor can't overclock.

DVI doesn't have official support via hardware vendors. There's enough engineering margin built in to cover up to 1440p@120hz. DisplayPort has enough bandwidth. These aren't 1440p 120hz monitors. They are 1440p 60hz monitors that happen to have the ability to overclock up to 120hz+. And...

Dual Link DVI is neither electrically nor signal compatible with HDMI. Any splitter would have to use an active "interlacer" to combine the two DVI links into a single HDMI link... which I can't find. Any "dual link DVI -> HDMI" adapter must have the active electronics; any of the short stubby...

*looks at calibrated Catleap* *looks at calibrator* Hm. I see a contrast ratio of ~800:1. I think you're mistaken about that. FRZ, the U2713hm would be a superior option - the question is what you are looking for though. It has better build quality, better warranty & support, better...

Seeing as how there isn't a 1440p TN panel at 60hz on the market... methinks that 1440p TN at 120hz is a long ways off.

You've got U3011's... Why not go for some higher-quality DisplayPort cables? DP -> DL-DVI adapters are notoriously finicky under the best of circumstances. 6m *is* a bit long, but if you have a high-quality DP cable, they should work just fine.

The X1 Carbon touch only has 5 hours battery life. It will not get 8-9 hours (although I'd drop the money on it right away if it did).

You may wish define "a lot of writing". Because as far as the engineers are concerned, "a lot of writing" = PiB (petabytes) of data. Thousands of terabytes of writes. You will not be able to meaningfully kill an SSD without actively trying to do it (it takes months of out and out full drive...
