• Can I drive two external screens from an 'Alu' iMac?

  - by robsoft

  I've got a 24" 2.4 Ghz Core 2 Duo iMac. It's about 18 months old, though I can't specifically remember when I bought it. It has a Displayport Mini-DVI socket on the back, and currently I have that linked to a DVI adaptor driving a Philips 20" widescreen monitor in portrait mode (awesome for browsing). I have another, identical Philips monitor and wondered if there was a way of connecting that to the iMac too. Is there such a thing as a DisplayPort Mini-DVI to dual-DVIs adaptor? Can this iMac's graphics card even drive such a set-up? The graphics chipset in the iMac is reported as ATI Radeon HS2600, 256 MB. The main iMac display is 1920x1200 and the Philips display is 1050x1680 (@60Hz, rotated 90 degrees). The third screen would be another 1050x1680 and ideally I'd have it portrait again, too. EDIT: Please let this question stand - it's not a dupe. The current Mac laptops use 'Mini Displayport' connectors, which are not the same as DisplayPort Mini-DVI connectors.

• Any reason to prefer video adapter with two DVI ports versus one DVI/one VGA for DVI/VGA optional dual monitors?

  - by Bryce Thomas

  I am looking to buy a new video card to power two identical monitors. The monitors came with both DVI and VGA cables, so I am able to use either. My current video card has two DVI ports on the back, so I have both monitors connected via DVI at present. I have noticed that many modern video cards have a DVI/VGA/HDMI port trio and that cards with two DVI ports seem somewhat more scarce. Essentially, I have more options available to me for purchasing cards with a DVI/VGA/HDMI trio than with a DVI/DVI duo. My question is, are there any sound reasons to go to the extra effort of finding a card with two DVI ports versus simply running one of my monitors through a DVI and one through a VGA on a DVI/VGA/HDMI card? Quality differences? Any variety of image asymmetry? Configuration difficulties (I dual boot Windows and Ubuntu)? Anything else?

• DisplayPort -> DVI Adapter, Active or Passive?

  - by Aren B

  I read somewhere that you only need an active adapter (usb powered) if you want resolutions greater than 1920x1200. I also heard from someone that you need it when running triple-monitor because more than two displays drains too much power. So to connect a 3rd monitor @ 1920x1200 to my video card's DisplayPort Port, do I need to spend the extra $100 and buy the active adapter?

• Multiple VM environment for developing/testing

  - by Hippo

  I was asked to create a setup for automated deployment, configuration, installation/updates of websites. A bunch of small websites will be bundled on one server. If more website will come up a new server will be created... I decided to us chef for this task. All servers will be running Ubuntu at the same version and configuration. The actual question: Everything needs to be tested properly before starting live deployment, so my question is: What is the best virtualisation tool to run multiple (5 - 10) virtual machines on a Ubuntu Laptop? Requirements: easy setup, fast (clone/snapshot of VMs) All VMs should be easily connected to the internet and should be able to communicate to each other (Open-Source / free would be great) So far I looked into: Virtual box is more for Desktop virtualisation, Cloning not possible, every new machine needs to be installed VMware Player Any suggestions? If there are any question about what I am doing please comment on this question, I will answer as soon as possible. This question is not about the actual set up, it is about a nice working environment.

• How can I play an online video in full screen AND type in a text editor at the same time?

  - by Edward Tanguay

  I watch instructional videos that play in Silverlight such as the ones at http://windowsclient.net/learn. I watch them in full screen on my left monitor. While the video is playing, I want to be able to type notes in a text editor on my right monitor. However, as soon as I press a key, the video exits full screen mode. How can I force the Silverlight player to stay in full screen mode even as I type in another application?

• Monitor connected with WiDi just shows a black screen

  - by Pops

  I have a Dell XPS 18 and want to use an external monitor with it. The monitor has VGA and DVI-D inputs. The XPS 18 has no video output ports, but it does support Intel WiDi. I have a Netgear P2TV2000 WiDi receiver, but it only has composite and HDMI outputs. I'm connecting the receiver to the monitor with an HDMI cable and an HDMI/DVI-D adapter. So, in short, the video path is: Computer → WiDi → WiDi receiver → HDMI cable → HDMI/DVI-D adapter → Monitor After setting all this up, I can't get anything to display on the monitor. At the moment I power the monitor on, I can see my desktop for a brief fraction of a second, and then everything goes black. All of the relevant drivers have been updated to the latest versions. When I use a different WiDi-enabled computer to connect to the same monitor, everything works fine. When I use the original computer and receiver to connect to a TV, everything works fine. It's only when I connect the original computer to the monitor I want to use that the connection fails. What could be going wrong here, and how can I get the video to work consistently?

• Sign multiple domains with single Domain Key (dk-filter)

  - by Lashae

  Motivation The private shopping website GILT, send periodical update emails from giltgroupe.bounce.ed10.net however all of the mails are signed with domain keys of giltgroupe.com. mailed-by giltgroupe.bounce.ed10.net signed-by giltgroupe.com My Story I couldn't manage to sign x.com with y.com 's domain key using dk-filter under Debian Lenny with postfix. If I try to init dk-filter service with following arguments: DAEMON_OPTS="$DAEMON_OPTS -d x.com,y.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" dk-filter service signs with domain x.com (d=x.com) If I change the daemon arg.s as following: DAEMON_OPTS="$DAEMON_OPTS -d x.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" then emails sent From y.com is not being signed. the dk-keys.conf file is as follows: *:/var/dk-filter/y.com/mail I managed to do same thing with DKIM, works perfect. However DK doesn't seem to work. I don't have any problem signing y.com's emails with y.com's key and x.com's emails x.com's key, which indicates there is no configuration problem. Do you have any experience/advice to make it possible to sign emails from multiple domains by a specific chosen domain?

  I'm now using three monitors with resolution capability of 1920x1080. The one monitor connected to Active Display Port is (from some reason) limited to 1440x900.

VGC(Video Graphics Controller) driver is up to date. Got this message:

• Dell PR03X port replicator and DisplayPort to DVI adapter not detecting second monitor

  - by yothenberg

  I have a Dell M4400 connected to a PR03X port replicator/docking station. I use the DVI port to connect it to a first Dell 2208WFP monitor and I'm trying to use a DisplayPort-to-DVI adapter to connect it to a second Dell 2208WFP monitor. The second monitor, connected via the DisplayPort-to-DVI adapter immediately goes into sleep mode and the laptop doesn't detect it. What is really weird is that it did detect it the first time I plugged it in but after I unplugged the monitor and plugged it back in it stopped working. I swapped the monitors round and it detected them both but after unplugging the monitor connected via the DisplayPort-to-DVI and plugging it in again it stopped working. Both monitors work if plugged in directly to the DVI port. Is there some way to force re-detection? Any ideas?

• How can I switch between the HDMI and DVI outputs of my graphics card?

  - by Owen Melbourne

  I've got an Nvidia GTX 560ti card which currently I've got my 2 monitors hooked up to using the 2 DVI ports. However its got a mini-HDMI port which I've plugged a HDMI cable in (with mini adapter) and lead it into my TV which is across the room. I'm hoping to be able to toggle between the HDMI output and the DVI outputs, however I'm not sure how I'd go about this, Could somebody please point me in the right direction, I'm not really worried about having all 3 on at the same time so that isn't a problem, but if its possible then I'll do that.

• Best way to mount 3-4 monitor like this?

  - by jasondavis

  I just purchased 2 HP 2009m widescreen monitors, they are not the biggest thing on the block, they are like 19-20" and are only around 150-200$ so I think they are perfect. I bought 2 of them just to make sure I like them, with the full intention of purchasing more to make either a tripple or quad display. I now I am stuck trying to decide, if I purchase 1 more to have a tripple display I would then like to just wrap the third monitor to either the rigth or left side, I could do this without a mount most likely pretty easy. If I decide to go with 2 more monitors to make a quad display then I would like to add the 2 new monitor directly above the 2 that I have now. So it would make a grid of 2 wide and 2 high. I have posted a few photos belwo to show them now with the 2 I have, you will notice that I have them tilted inwards to make more of a "V" shape instead of them being side by side and "STRAIGHT". Now if I decide to make thegrid of 4 then I will need to buy or build a stand to hold them all tightly together (no whitespace or gap between the grid of monitors) but I would like to still have both rows invert to make the slight "V". Do you know of any existing stands I could purchase that would hold all 4 monitors without making them be STARIGHT without the "V" shape? Any tips appreciated please, also they do have holes in the back for VESA. a few photos... (they are from iphone and lighting made them note very good but you can see what I am working with here)

• How do I disable other monitors while running games in Wine?

  - by Michael Cheng

  My current setup is: * Dual GTS 250 video cards * 3 Monitors * Used nvidia-settings to run each monitor as a separate x session * This is all running on Linux Mint Debian Edition When running games (Starcraft II) in Wine via PlayOnLinux, I've found that the mouse does not get locked. I already tried various solutions littered across the web and none work so I'd rather just disable my other two monitors while playing. Does anyone know of a method where I can turn off my other two monitors (not my primary monitor) while running Wine and then turn then back on afterwards? I don't mind having to manually run a script before and after gaming. Thanks.

• Eyefinity with lower power graphic card?

  - by terrani

  Hi, I am looking for a graphic that supports Eyefinity, but with lower power. What I mean by "lower power" is lower performance and lower power literally. I don't need performance and heat of ATI 5 Series, but I love their multi-monitor supports and price range. What options do I have?

• multiple streaming servers behind a Bastion Host

  - by Bond

  I am using open source streaming server Red5 on multiple servers. Which are running behind a bastion host. the world knows these sites as http://site1.mydomain.com http://site2.mydomain.com http://site3.mydomain.com http://site4.mydomain.com To reach the front end server is using Apache Reverse Proxy. I am also having video streaming on each of these websites using rtmp. To be able to reach the streaming server I embed a javascript in HTML pages as follows Code: <embed ..... var="rtmp://site1.my_domain.com" > the problem is the website are many site1.mydomain.com site2.mydomain.com site3.mydomain.com site4.mydomain.com each on a separate physical server. Each of these four have their own Red5 installations the front end to each of these four is a common Bastion Host. If I run rtmp on each of the subdomains at a different port how will I make sure a request such as rtmp://site1.mydomain.com rtmp://site2.mydomain.com goes to their respective servers. from the front end server. What do I need to handle in this case ? IPTABLES came to mind instantly but from the client browser on internet when some one requests rtmp://site1.mydomain.com how will I make sure this rtmp request is mapped to a port different than 1935 as there are three other streaming servers which are also to respond to their respective requests ?

• Can Acer Aspire Revo (Atom 330) be used with two monitors simultaneously?

  - by LeeD

  I'm so attracted to Acer Revo for the price & the look. As long as I can work on two monitors simultaneously, I'll be happy. Not planning to do heavy video editing or gaming. Occasional movie streaming would be fine. Will mainly use it to do trading, lots of word processing, some photo editing, connecting with friends. Anyone has experience using Revo with 2 or more monitors? The spec says it has VGA and HDMI output but Acer sales person over the phone told me it can support one monitor only..??

• Colors differ in the dual monitor

  - by becomingGuru

  I use a dual monitor. The colors appear entirely different on the new monitor than they do on my laptop. When you are selecting colors etc, to be included in a website design, it totally freaks me out. Is there no software solution that finds how the settings of one of the monitor is and puts that to the second one? Otherwise what all settings do I need to change manually on the second monitor to make it appear as it does on the laptop? Thanks in advance.

• LCD monitor flicker when connected to a laptop using VGA

  - by Björn Lindqvist

  I have a dual screen setup with two AOC e2450Sw monitors connected to a laptop. The laptop has one HDMI and one VGA output. When one of the monitors is connected using VGA, it flickers or displays static noise. The flickering is fairly subtle and only visible on darker colors. But it is there and noticable and appears like horizontal lines. The problem only appears on the monitor connected to the laptop using the VGA cable. If I swap the monitors, the one connected using VGA is displaying the flicker but not the one connected using HDMI. The simple solution would ofcourse be to connect both monitors using HDMI, but since the laptop only has one VGA and one HDMI out that isn't possible. I've tried tweaking the monitor setting using the OSD menu, but it had little or no effect. Update: After several more trouble shooting hours, it seems the problem is not related to the monitor or VGA cable as the problem persists even if I swap the display with another brand and different cables. So it may be the graphics card? Intel HD Graphics 4000. The laptop is Acer Aspire E1-571.

• Insulate hosted client domains from server IP address change?

  - by babtek

  I will be hosting web content for many client domains on a single IP address (with a web hosting company, not inhouse machine). Initially, I must give client some information to configure their registrar to point the domain to my server. I want client domains insulated from a potential IP address change, so if I change hosts/IP address they don't have to reconfigure anything with their registrar. Is this reasonably possible without running my own nameserver? If so, what would be the smartest way to make it happen? Instruct clients to make CNAME record? Use some type of DNS management service that clients would use as a nameserver?
