I really wish it had a touchscreen as well. I'm still going to get this but does it work with windows? I"m assuming so as its just a windows monitor. I do a fair bit of mobile dev work and this will be invaluable for testing...maybe I will get several of them.

Jim_Good question, we haven't tested it on Windows, but if you buy something like this: http://www.amazon.com/Startech-DP2HDMI-DisplayPort-Adapter-Converter/dp/B0017K6BDW it might work. Let us know if you want to cancel your order by emailing support@massdrop.com

Jim_There should be no reason why it doesn't work with Windows. The Qualia, being built off the same display as a Retina iPad, pipes the DisplayPort connection directly from the machine to the display. It doesn't do anything special to the signal that would prevent Windows from using this.*
* I do some design work and I've followed a guide someone wrote on converting my Intuos into a faux-Cintiq with the same iPad display. No problems on Windows or OSX with the display.

andyI have display port so I think it should work. I think any new computer should have display port. I more specifically know some higher res monitors were not working under windows but I bet it will work.

jaesondDO you have a link to the faux-cintiq? I tried this a while back and had pretty good results but the mointor I used was too bulky. This seems great for such a task

andyThat won't work. You need to drive the panel at native resolution, which you can't do over HDMI.

andyI got this in the prior drop. The description should clarify that the included cable is DisplayPort-to-MiniDisplayPort. The Qualia uses the regular size end, so your source needs to be MiniDP unless you buy an adapter separately. It works fine from my Windows laptop that has MiniDP output, and also my Windows desktop using my own DP-to-DP cable since my video card only has DP output, not MiniDP.
However, be careful with that linked DP2HDMI adapter. The passive adapters are only changing the shape of the interface, but not the signal type, in one direction. Going from HDMI to DP likely require a more expensive active converter.

Jim_Older versions of the HDMI standard didn't support super high resolutions well, but there's nothing about Windows that would stop higher res monitors from working. But Windows still stinks at DPI scaling and font rendering when it comes to high PPI displays. If you're using the Qualia to preview web work for example, the OS/application/browser may all apply different scaling factors, so what you see isn't necessarily what another user would see.

SL75thanks for the info! I believe their was an issue with windows and titled 4k monitors a while back but I can't seem to find any references so I may have made that up :) I guessing this is driven as one so it shouldn't be an issue anyway. Definitely not looking at HDMI as I use display port exclusively. Would be great if someone made a vesa mount acrylic and I could slap this on an ergotron arm.

andyI think that adapter is for connecting a DP source to an HDMI display, not for connecting an HDMI source to a DP display.

Jim_You're referring to Tiled mode, I think. Most 4K screens pretend to be 2 screens in Multi Stream Transport mode so they can use 2 scaler chips (because older scaling chips aren't designed for this many pixels). This display does not have a scaler, so it doesn't apply.

Jim_Sorry it took a while, Jim. Hackaday did a report on it with links: http://hackaday.com/2014/06/08/converting-the-wacom-intuos-into-a-cintiq/

Jim_It seems like a few people have tested this screen with an intuos, but please don't assume that testing the screen alone is enough to hack a DIY cintiq together. Often times the cfl power inverter will cause a large amount of interference with the wacom tablet, which will make your cursor jitter like mad. Unless someone has tested this specific backlight and monitor combination, this may not work well as a DIY cintiq.
