I found the problem myself. The problem is in the display. I tried another display and the problem went away. Thank you @AndrewMorton for your help!

I was a bit disappointed about the lack of response to this question, so I ended up taken matters into my own hands and went ahead and tested it myself. Currently, I can drive a Dell Ultrasharp 27 u2713hm at 40hz with reduced blanking using the hdmi port on my laptop with a 4k hdmi cable in both Windows 7 and Ubuntu 14.04. To do this in Windows 7, I went ...

Here is a really proper answer. Due to Surface Pro 2 have an i5-4300U CPU which have integrated Intel HD4400 GPU, it natively supports three displays over a single Mini DisplayPort. The feature is called Multi-Stream technology and you will need either a Multi-Stream Transport hub (MST hub — just like familiar USB hub, but for displays) or compatible ...

You're looking at it the wrong way round. It doesn't start Thunderbolt to HDMI... it ends HDMI to Thunderbolt - though you'd be better off going straight from Mini DP >Thunderbolt... ...except that http://support.apple.com/kb/HT5219 would lead me to believe it can't be done.

These may shed some light: http://www.bluejeanscable.com/articles/how-long-can-hdmi-run.htm http://www.datapro.net/techinfo/dvi_info.html It appears that DVI is good for up to 16 feet without a repeater; HDMI in the range of 33 to 45 feet. You can go farther with high-end cables and other tweaks.

You should extend your bootargs to force the kernel not to use LCD. Do you use GRUB or LILO? I bet you use GRUB, so you should extend your GRUB_CMDLINE_LINUX_DEFAULT (/etc/default/grub) with the following: video=LVDS-1:d "d" means disable. The kernel should use the external video's native settings, but if you want to precise it you should add another ...

Pretty sure DVI doesn't support audio, so if you're trying to get audio across you might be out of luck, but otherwise HDMI can be thought of as a superset of DVI in many ways, and is designed to support interoperability with DVI. In summary, yes, a DVI->HDMI cable should work just fine. I've used them in the past for my PC and they've worked just fine.

I have been using converters and combined cables (all of the above) back and forth (for computer monitors and for televisions) -- they work very effectively. The real difference is that the HDMI cables can include audio, but DVI cannot so connecting the two will filter out audio to the DVI end. One piece of advice however, don't get extremely long HDMI ...

No you cannot. The hardware does not support using the ports as input. However, internally the MacBook Pro uses DisplayPort. If you wanted to disassemble the machine you could rewire the display to act as an external monitor. Tutorial here: http://mikesmods.com/mm-wp/?p=384

HDMI splitters just duplicate the screen (so you'll get two screens showing the exact same thing). If you want to extend your desktop (ie, have both monitors either show up individually on your computer, or have your computer output to a double width screen which the HDMI splitter then splits and displays on half of each additional screen) you'll be facing a ...

With the small amount of information you've given, it seems like you've extended your display instead of mirroring it. I would suggested trying to drag an open window to the left/right/bottom and top of your laptop screen to see if it appears on your TV.

On a Dell Inspiron 15 (3537), I had the same problem with Debian Wheezy, and it appears that it is too old to properly deal with Intel Haswell kit. I couldn't find a way to make it work. Upgrading to Jessie (testing, but on the verge of release) solves the problem and all the laptop hardware works perfectly.

You can't, but Debian Jessie seems to work perfectly with all the hardware on a Dell Inspiron 15 / 3537. Upgrade.

Should be fine if you only need 1080p. Issues only start if you need 2k resolutions, as then you must use HDMI 1.4 throughout.

Forget it. The Chromecast requires an internet connection in order to work. You will not be able to set it up on a router, until it detects an internet connection.

I've tested this a bunch recently and using an HDMI splitter solves the tearing problem. I have a motherboard with dual HDMI out and Intel 4000. When using cloned mode, the secondary monitor has horrible tearing, but with several different HDMI splitters I've tried and single monitor mode, I have no tearing on either monitor.

Find the graphics card with the laptop, most likely will be integrated graphics that comes with your CPU. Then search to see if that supports 4k monitor. The intel i5-4xxx processors do, for example, as Intel Graphics 4000 seems to support 4k. I think the best approach is to ensure you're getting a latest-generation CPU, find one or more machines that ...

You cannot do this using the cables you have available. Both the MHL-to-HDMI and HDMI-to-VGA adaptor cables are "active converters". They have proper electronics built in to them and actively convert one signal type to another very different signal type. Because they are active cables they both need a power supply. The MHL cable has a power supply: ...
