I am kind of new to Ubuntu. I have an i7-7700 with z270 motherboard and hd630 graphics. I have 2 LG 24mp68vq displays. I have connected one of them with a VGA cable and when I try to connect the second one with HDMI, neither of them shows any picture.

I'm running Ubuntu 12.04 on a Lenovo x61s Thinkpad. As the screen's rather small and I want to do some video editing, I thought I'd plug in a monitor and use that. The monitor is Relisys JM777 (quite old).  When I plug it into my other computer, which is running Windows 7, it immediately mirrors the display; but when plugged into the Lenovo the monitor screen remains blank. The graphics card on the Lenovo is a "VGA compatible controller" according to SysInfo.   Anybody got any suggestions for getting this monitor to work? I'm quite new to Linux.

My monitor supports full-resolution display (2560x1440) only when connected to through either the DVI-D dual link port, or the DisplayPort.  My laptop, though, has neither of these two kinds of output. Instead, all it's got is a HDMI port (which is version 1.3, and I also read that the laptop's graphics chipset supports 2560x1440 at 60Hz).  So I'm wondering whether anyone has ever seen an HDMI-to-DVI dual link adapter, which will carry my ultra-highres signal to the monitor I just bought. So far I haven't seen any, and don't even know whether such an adapter (which I understand would have to be active, USB-powered and expensive (but I don't care)) exists.

Newer Radeon video cards come with four ports standard:   DVI (x2) HDMI DisplayPort     If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert?  I did a little research and it looks like there isn't a simple "dongle" method. I found this  but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point!  There's also a  but I'm not sure it will work, either.  AnandTech seems to  that you do need the DisplayPort-to-DVI:     The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

I try to find what graphics card I'm running, the commands in terminal only gives me this:   VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller.    How do I install the correct driver? As I can see that not everything is displaying correctly. I want to set a proper resolution, but can't as I don't have the right drivers on my Ubuntu 12.04 machine. It's an Acer Aspire One netbook.

I am researching on hardware requirements for my new PC. One of my requirements is to have dual monitor display to use while programming. I understand that most integrated graphics cards do not support dual monitors (?), and I will need a standalone graphics card for this. But I also want a quiet PC, and graphics cards can be quite noisy. I am not a gamer, and other than dual monitors, I don't anticipate much need for a dedicated graphics card (though an added boost to UIs would be a nice to have).   What should I look for in a low-end, relatively silent and less power-hungry graphics card for my purpose?  How do I calculate how much memory it should have?  What should I look for in terms of output ports? (I am intending to use two 22 or 21 inch 1080p monitors - an area I need to research into as well).   I will be running Windows 8.1.

I have scoured the Internet and come here as my last hope.  I currently have the Galaxy S4, M919v. I own two 24 inch Samsung monitors.  Is there any method for me to display my Android screen onto one of my monitors?  I want to basically play my Android games, using my Android phone, but have them displayed on my monitors. My 24 inch monitor has the same resolution as my phone, so I figure the graphics should be great.  I am trying to find a WIFI/micro-usb cable solution to this problem without buying any types of additional connectors.

I'm using:   Alienware M14xR2 laptop running Ubuntu 14.04 2 * DELL U2412M monitors attached via HDMI and Mini Display Port Optimus graphics (Intel + nVidia GeForce GT 650M) running with nvidea-340 and nvidia-prime, with Prime setup in nvidia-settings GUI to use the NVidia GPU built-in laptop monitor disabled   Unfortunately, the monitors only work successfully in the default mirrored setup - I have the following issues trying to get a dual external screen extended desktop to work:   nvidia-settings GUI can only see one monitor on the X Server Display Config page. System Display GUI can see both displays but can only mirror the displays successfully. By fiddling with Display GUI and ARandR, I temporarily managed to get an extended desktop working, but NVidia GUI still only sees one of the monitors and if I try to reboot with 2 monitors attached, the GUI is totally glitched and unusable after login. During boot, the system just uses the left monitor (via HDMI i/f) for display, so I presume this is treated as the primary display. However, after boot, it appears the system switches to using the Display Port for the primary display and the system will not let me have the Ubuntu launcher only on the left (HDMI) display. The only options that work are for having the launcher on both or just on the right (Display Port) monitor. I tried to forcefully fix the issue with the primary monitor incorrectly being set to the right monitor by changing the primary monitor switch in ~/.config/monitors.xml, however this does not work and causes both monitors to appear at strange resolutions and glitch badly with uncoordinated mouse input.

I have a 3 display windows 8 system.  Two are 24" monitors and one is a 27" monitor.  The 27" monitor is in the middle and one of the 24" monitors is flipped portrait on the right.  When I go to the screen resolution dialog box in Windows the 24" monitor and the 27" monitor appear to be the same size.  This means that the edges of the window don't line up.  Similarly the 27" monitor and the portrait monitor don't line up in the sense that when the mouse goes from the top of the 27" monitor to the portrait monitor, the pointer jumps downward.  However if I go from the bottom of the 27" monitor to the portrait monitor the pointer lines up correctly and transitions smoothly.      The screen Resolution window correctly identifies my 27" monitor as a Dell S2740L and the driver is up to date.  Also if it is relevant, the 27" monitor is hooked up using HDMI, the left monitor is hooked up using DVI and the portrait monitor is hooked up with HDMI -> DisplayPort with an Active HDMI to DisplayPort adapter.

I have a DisplayPort based monitor, and a laptop with a DP out.  I recently got a second laptop with HDMI out, and went looking for a HDMI -> DP converter.  I was very surprised to find that such a thing effectively doesn't seem to exist.   and the  seem to imply that it's just not possible to go HDMI -> DP, without a very expensive converter box (not just an adaptor).  However, I can't find anything that explains why this is the case.  Is DP designed to be backwards compatible but can't interpret HDMI?  Is it a case of HDMI-quality signal not being high enough quality to be convertible?  Some other reason?  Note that this question is not looking for an adaptor - I'm looking for the underlying cause of the lack of them.

I purchased a new Lenovo g580 laptop. But I am totally disappointed when I installed Ubuntu on it. Almost all drivers are not working. :-(  The laptop configuration is  intel i3 processor  Nvidia GeForce 610M graphics card.  I couldn't find the nvidia drivers in the additional drivers (jockey).  The main problem is that the brightness control not working. I tried lots of methods explained in this site, but the result again disappointed me.  I am a student and I am using Linux, and the brightness control is the most urgent problem that have to be solved.  So experts please give me a solution.  thanks in advance

When OS installed, I found there is only one option in display setting: 1024 x 768 (4:3),  My monitor is a HDMI monitor with 1920x1080 resolution  Do anyone have any idea how to make the resolution setting right? Thanks.  BTW. I do not install any graphic card, I use the internal GPU of Intel

While trying to spec out a Lenovo T440p ThinkPad with Nvidia graphics and a docking station allowing for dual monitors, I found a  implying that the Nvidia Optimus could not be used with docking station outputs.  This claim was made from display topology information found in a :     Since Optimus Technology has the ability to use two display adapters, some    display monitors (or displays) are assigned to specific adapter. Below    describes which display adapter controls the display connector for a certain    display monitor.      Thinkpad T440, T440s, T440p, T540p   Intel HD Graphics      - (Computer's LCD)      - Computer's analog VGA connector      - Computer's DisplayPort connector      - Docking Station's analog VGA connector      - Docking Station's DVI connector(s)       - Docking Station's DisplayPort connector(s)      - Docking Station's HDMI connector  NVIDIA GeForce GT 730M, GeForce GT 720M      - No display is connected to this display adapter.    What good is the Nvidia adapter if it isn't connected to any display?  I assume there is more to the story here, but I am not familiar with how these two graphics adapters interact with each other.  Is there any way to use the Nvidia adapter with docking station ports?  And if not, how does the Nvidia adapter work at all?  The text file goes on to talk about "standard mode" and "advanced mode".  The "advanced mode" seems to allow more display pin configurations, but isn't available on the T440p.  There is also a note about cross-adapter display cloning, but I do not believe this applies to my situation.
