No event in Udev upon connecting a DVI-HDMI display

Hi all!
Im pretty new to Archlinux and sarted "linuxing" generally not so long ago.
Arch is my latest stop and love-for-first-sight, learned a lot from its wiki and forum.
I tried to cook (honestly more like copy) a script today to let KDE (xrandr) automatically configure my TV, which is connected with a DVI-HDMI cabel through a HDMI switch.
As per instructions i tried to check out its proper name with
udevadm monitor
but there r absolutely no events in it.
Im guessing thats why my script isnt invoked upon connecting/disconnecting.
Also, even if i connect/disconnect TV, KDE generally does not get it untill i let Display Settings run or
xrandr
from terminal.
That means if i disconnect, then reconnect, my settings r still the same. If i run any of them in the while, or boot up Linux so that my TV is turned off, i loose my settings.
Is that normal?
What can i do that i can get udev events?
Thanks a lot for your help guys in advance!
EDIT:
Two more things
Disconnecting my primary monitor shos nothing as well at udevadm monitor.
Interestingly DVI-0 is my TV with DVI-HDMI connection
HDMI-0 is my primary monitor with DVI-DVI connection.
Kinda weird.....

DVI/HDMI connection for Thinkpad R61 (with IBM 2504 Docking station) and Samsung LNT4665F LCD TV

I am trying to connect my laptop (Thinkpad R61) with my TV (Samsung LNT4665F) using a DVI/HDMI cable. Because the R61 doesn't have a DVI port, I am using it in the IBM 2504 Docking station. I have docked the computer, connected the DVI/HDMI cord (using HDMI in 1 on the TV, which I believe is the only DVI accepted HDMI on the TV). I followed the Samsung instructions to then hit "Fn-F7" on the laptop. Unfortunately, nothing is happening. It doesn't appear that any signal is pushing out to the TV.
I am not very tech savvy. Can someone please tell me what I need to do?
Thanks for your help.

if your R61 uses an intel GPU, then it won't support the dvi passthrough port on the dock.
The 14" models with intel GMA have DVI pass through.
@ bweisy, welcome to the forum,
Which model R61 do you have? Could post the Type and Model Number Please do NOT post your s/n.
Thanks

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks

Any ideas?

How to connect two DVI screens to Thunderbolt Display's Thunderbolt Port?

Hi everyone,
I have a new MBP and an external Thunderbolt Display. The Thunderbolt Display itself has a Thunderbolt port, and I was wondering if there is anyway to connect to DVI screens to that. My goal is to have the Thunderbolt Display and 2 x 24" Samsung DVI screens connected to my MBP.
Alternatively, has anyone had success using a third party device like the Matrox 2 go to drive multiple monitors from the usb port?
Thanks,
Dave.

You could try a TB>DVI adapter (here's one from Monoprice) but I don't know that it will work - I'm thinking that you could have at least one of your Samsung displays use it. You may also want to see if you can find a HDMI>DVI adapter for your second Samsung display - something like this?
I know that I've seen three monitor set-ups on YouTube - but I'm not sure what was connected to what. Easy enough to daisy-chain ATDs but it gets a bit tougher when utilizing HDMI ports, etc., and I'm not sure about the GPUs ability to drive all three displays.
Oops - sorry - strike that second paragraph - I thought that you were running a Retina display MBP...

Connecting MacBook to Sony Bravia via DVI-HDMI!

Hi I am having major issues with my Macbook connecting to my Sony Bravia KDL-32V4000 I now have 2 different DVI-HDMI leads as well as the Apple Mini-DVI-DVI and still have absolutely no luck.
The Macbook is picking up the Television absolutely no bother at all but there is just nothing at all coming up on the Television its self it doesn't even recognise that I have the computer in the HDMI slot nothing at all just blank!
Any help would be greatly appreciated as it will save me buying more and more cables if this fails to work will have to go with the DVI-VGA I guess would rather fix this though!
Thanks!

I bought a mini-DVI to HDMI and an HDMI to HDMI cable. Once I went into settings for the display, I found that the TV was acting as a second monitor and that it was off to the right of the macbooks own screen. Thus if i moved the mouse to the right it could control the second monitor. You are able to move the screens so that they have the same data on each or use them as two screen with different info on each. Each screen is clearly visible in Spaces and it works a treat.
It is also possible to use the TV as the only screen. The way to do this is to connect up and close the lid on the mac. Once the light on the front starts blinking you can wake it up by using your mighty mouse or external keyboard. once awake, assuming you have chosen the correct HDMI connection from the TV the TV will act as the only monitor at full resolution.
The problem I have, is that I have not been able to get the sound to work. I have used the earphone socket and connected that to external speakers as I cannot seem to get the analogue signal on the TV on anything but an AV channel (not an HDMI channel). Thus the sound works on one channel and the image on another. My TV is a Sony KDL40w5710 - thus if anyone know the solution to getting the sound running through an HDMI channel on my TV it would be appreciated if you could contribute.
Cheers

MacBook Air mid-2013 OSX 10.9.1 cannot connect to DVI Monitor

Does anyone else have this problem? I've seen similar issues raised, but so far can't find a solution to my particular issue:
MacBook Air Mid 2013 (ordered Jan 2014)
- 1.3GHz Intel Core i5
- 8GB 1600MHz DDR3 RAM
- OSX 10.9.1 Mavericks.
When I connect my MacBook Air to any monitor (well, I've tried three monitors: Benq, NEC and Samsung) the monitor will not detect an attached computer. The MacBook also does not think it's connected to an external display.
If I connect via VGA cable, it works fine most of the time*, so the display port seems to work only for VGA and not DVI.
I am using mini display port adapters (DVI and VGA) purchased from the Apple Store.
The adapter for the mini display to DVI works fine, since I can get my 2009 MacBook unibody to connect to an external display via DVI without issue. So it's not the adapter, or the DVI cable.
I have tried resetting the System Management Controller for my MacBook air but it does not work. No matter how many times I reset the computer (Hard reset, Soft power down, SMC reset) I cannot get it to connect via DVI.
Has anyone experienced this issue, or seen a resolution for it?
*The only other symptom I get periodically, is that after being disconnected from a VGA monitor, the computer will periodically (about 2/5 times) not connect to the VGA monitor either without a reboot. However it will connect most of the time, and ALL of the time after a reboot.
Thank you

Thanks themachead: I have tried the adaptors on different macs, as I indicated in my post. The adaptor works fine with a different mac
Yes, I have also tried starting up with the monitor connected, and disconnected.
I just got off the phone with Apple Care. They couldn't solve my issue through normal means, but during one attempt, we closed my MacBook Air while it was connected to the external display, with my Magic Mouse and Apple Keyboard connected via Bluetooth. The external monitor did not come on. However when I opened my Macbook Air's screen, we saw that my Mac had crashed and prompted me to reboot. When it did, the external monitor worked. I have been able to disconnect and reconnect the monitor and it seems to be working now. I will see what happens after a few attempts.

How best to get my vga Powermac G4 connected to my new dvi Cinema Display?

Hi Folks,
My new 23" Cinema Display has arrived. That's the good news. Of course I checked Apple's site before the purchase, to be sure the new monitor would work with my very old G4. As soon as I saw the line under System Requirements where it said "G4 or G5 Powermac or Powerbook", I thought I was covered. Now I find MY G4 has a vga connector and not a dvi. Thereby hangs the bad news.
Does anyone make a pci-based video card that will let me connect to the Cinema display? Should I be looking into one of the vga-to-dvi boxes that Gefen Inc. makes? Other strategies?
Many thanks,
Rod

The ATI Radeon 9200 PCI card with 128MB VRAM has a DVI and VGA port IIRC. If you still have the original Rage 128 in a PCI G4 (Yikes G4) then it wouldn't support the monitor without an upgrade anyway, the 23" requires at least 64MB VRAM (maybe even 128MB) IIRC.

My macbook mini DVI-HDMI won't connect

i recently updated to Lion, and now my mini dv-hdmi wont work? i have the adapter from apple and the HDMI is a belkin dvi-hdmi, and now it wont even connect to my tv does nothing. is this a known software problem? : i used it before the update.

Unfortunately I am having issues with my HDMI connection from a Late 2008 MacBook to a 37" Phillips HD TV. When I connect the two a notice stating that "Format is not Supported" appears on the TV screen. Why did you do this to me Lion, WHY? I was unable to make a presentation because of this fact. Unsatisfactory!

Is there a way to connect my MacPro (with DVI and Display ports) to the new Thunderbolt display?

I'd like to connect these devices together.

As Kevin J. Doyle points out, the displays from NEC are better than what Apple has to offer for graphics. For video, you'll need a broadcast capable monitor for accurate color correction. Not a computer monitor.
The 24" model is under $1,000 and it include color calibration items. It has both DVI and Display Port connections. The base can be raised/lowered as well as tilted. (the Apple display does not)

They have other sizes and resoltuions as well.
Here's a review on the NEC displays.

HT5918 how to connect 6 DVI Displays to MacPro

Apple states can connect up to 6 DVI displays to a MacPro explanation is not clear. Mixes Mini-Display and USB terminology. What does it mean?

The article you linked to includes:
Mac Pro supports a total of two single-link DVI displays. If you connect a third DVI display using a passive adapter or a display via HDMI, it will cause one of the three displays to become inactive.
Can I connect more than 2 DVI or HDMI displays?
Mac Pro supports a total of two DVI or HDMI displays when connected via the built-in HDMI port or using the Apple Mini DisplayPort to DVI adapter. To connect additional DVI displays, use an active DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter. You can connect up to six active adapter DVI displays. This requires a powered USB hub since Mac Pro offers four USB ports and you will need six to connect them all.
If your display are 1080p pr less they you can use 2 standard/passive mini displayport to DVI adapters and 4 active mini displayport to DVI adapters. If 1080p or less you do not need the dual-link adapter which are active. Yo can get less expensive active adopters.
If any of your display are greater than 1080p you need the dual-link adapter. Those included a connection to USB for power. These cost about $100 each for the Apple branded ones

Single DVI connection to DVI - DVI - Y cable hook up

I have an HP Envy H8 1500 DT - with an AMD FX(tm)-6120- Six Core Processor running WIN 8.1 - and thought I could connect two DVI monitors to my one DVI port on this machine by using a DVI Y Cable. Both monitors work with the cable but the option in preference - says it can't detect two monitors? Do I need another device/adapter?

Lost the monitor after connecting via DVI

I've had an X2Gen 22" monitor connected to our G5 via DVI/VGA adapter to the VGA input on the monitor for a couple of years. Another monitor I just bought came with a DVI cord and a VGA cord. I decided to try the X2Gen/G5 connection via DVI since I now have a cable. The computer can't/won't recognize the monitor now that they're DVI connected. And screen images are ugly! I can't even calibrate it because the computer tells me it cannot identify the monitor. Any ideas anyone? (Other than going back to the VGA cable?)
Thanks,
Jon

Just a thought, but try zapping the PRAM. Good luck.
