Port of question - no video - DVI double separator i7-HDMI > DVI

What I'm missing here?

I have an i7 2.3 g-Mini late2012.  10.8.5. in a studio where I fed a dual display

using a separator of video signals by - everything first, Tripp Lite, now an Aluratek - DVI 2-port video splitter (powered

units).

Followed by all the good order in start-up, the device worked for maybe a week and a half.

Walked away and returned after maybe 48 hours either from Friday to Monday.  Computer is running

"sleep" mode... The attempt, no signal wake video monitor not recognized.  Powerd deactivation/activation, no change.

Reset PRAM and disconnected/reconnected Mini power after 30 seconds... tried reconnect splitter/monitors...

sequence... still no resolution of the video signal to not watch.  Indicators on the splitter show the signal of the i7.

and connectivity to the monitors.  I excluded this device that the fault.

Am following the process mfgr correct insofar as the separator like so new out-of-box in reconnecting

power on it - getting nothing.  Strange thing is, I had the same problem with the Tripp Lite - that's why I

bought this Aluratek separator to replace.  Now, same problem.

When connected to same monitors, this worked fine right out of the box.

Now the same problem as the other separator.  Changed two different HDMI > DVI

cables. All cables. No change.

Either monitors directly linking ON the HDMI Mini port - display works fine.

Tried the MiniDisplay port to the separator. didn't work...

Which may conflict in operating system - something making these monitors sleep, something system-wise

who is disrupting this process?  Even pulled all other connections (external USB port stuff) and it

did not solve.

It is also a coincidence for two separators to fail with this same issue - seems to indicate something with the

Mac. In the meantime, no double posting until I can understand it.

Any help greatly appreciated-

Thank you

Mike

I suspect the power adapter... and maybe check for a loop of mass too.

  • Video card double slot.

    Hello, so I have a hp p7 1226 s and I wanted to install a ti gtx 650 or a radeon 7770. The poroblem is that they are both cards double slot. When I was last upgrade of the gpu in this Office I noticed that the second location may not reach easy to remove. I was wondering if the second location is removable, or if anyone could tell me how to remove the second cover of the location. I see it has an icon of a screwdriver on the back of it, but the problem is that I don't know where is the screw if it is on the second slot. I'm eagerly looking for information but nothing to really is as far as I can see on the internet, so I came here hoping that someone knew how to remove or if you can remove the second slot cover on the back. I really hope there is a way to remove it, otherwise it will be a big problem for me separator because I'll have to buy a new case so that I can hold a video card double slot for this pc.

    Hello

    The leg split with the screwdriver on it requires a screwdriver to be inserted in a slot in and waved the screwdriver back.  Do it a few times and then move to another location on the baracket and repeat the process. Subsequently the support stands.

    I find it interesting that adjacent the bracket with the slot PCI-E x 16 slot support seems to be a fixed location as something occupies the PCI-E x 1 slot internally.  Is this the case?  Sometimes the media raise just to the top and outside according to the PC.

    Hello

    First of all what you should check that the "videos > monitors: role" is set to Dual and you can then configure the output HDMI mode primary, secondary or presentation only.

    This can be done through the WEB user interface or via the CLI over SSH

  • Question about video drivers Satellite P100-257

    Hello.
    Question about video driver. Version 14.25... Works (tells... 945 GM chipset); 14.27--works but with ocassional problems (tells... 945GM/GU); version 14,29... (said 945GM/GU) - does not work at all - black screen, but you can hear sounds which tells that XP does all right.

    Why that? And what is GU? Pilot info says it is for 945GM, pilot says he's for 945GM/GU.

    All kinds of three said they are for Mobile Intel 945 GM Express chipset. Who initially my machine have said there. In section "video card" my machine said no Intel - some Calg... - don't remember exactly the name.
    Thank you very much.

    Hello

    As much as I know Satellite P100-257 supports the graphics card Mobile Intel 945GM. The code name of Intel's GM Calistoga
    This is not the same thing as the chipset Intel 945GM/GU. Both are different and so the graphics drivers are not totally compatible!

    The Intel page provides some interesting info on these chipsets:
    Mobile Intel Express Chipset 945GM

    Unfortunately, I have not found anything on the 945GM/GU.

    As Tom SC replied, you must contact the company that manufactured your computer.  In general, the ports HDMI on most computers is an out-bound port, send video / digital audio output.

    You should probably use a video capture card that can capture from HDMI source,

  • I need a video card double for it what kind I can use. OS is XP 32 Bit.

    d7900C; It is a Minitour convertible Hp. I have a card from Office Max, and the PC gave me 6 beeps. The user is eager to use two monitors and have a screen that is divided between the two.

    [number removed for privacy]

    Hello:

    6 beeps is a video card error. I guess that the card is bad or not compatible.

    Get a Radeon HD 6350 512 MB video card with the DMS-59 port.

    This requires a video cable to split, which can operate 2 monitors out of the map.

    Or you can get a Radeon HD 6570 1 GB video card and pass a DVI and a VGA cable up to two monitors on the ports.

  • Upgrading the video card to have both HDMI and DVI

    I just bought a model 700-327c HP Envy.  I need to update my video card to have the two HDMI and DVI on the same card.  Y at - it all the features that I need to worry about replacing my existing video card?

    You are welcome.

    Yes, it is certainly an option.  Here is an example of an adapter that you could use.  There are 2 ports USB 3.0 on the back i/o ports.

    There are others that can add up to 6 monitors to a single computer.  I am not sure that this would not require an upgrade of the power supply, however.

  • Upgrade to a video card double

    I bought a new computer and need to upgrade the video card to use in our Church.

    The new computer is a HP SLIM s5580t Intel (iona), has window Home Premium, Intel Core i5-650 (73 watts)

    6 GB PC3-10600 memory. Can someone suggest a compatible video card that I can use to connect to some projectors?

    Will need double connector VGA...

    Thank you!

    The card mother Iona comes with both VGA and DVI connectors, which allow the double output. For you, the main constraint is that DVI requires a DVI monitor.

    For a map, you need to map PCI-E x 16 probably of low power and a low profile. You might be limited with being only 220 watt PSU.

    A low cost LCD with DVI input may be a better solution, with the projector using VGA.

    See you soon,.

  • I Production Premium CS6 and will have questions, see videos and pictures.

    I have not had any problems for several months, then a month ago, I slowly begin to have problems with the video only appears in the first.  Restarting the application or the opening of another project cleared up questions until recently, when it works autour stopped working and I can not play video or see all the images in the first.  If I change the workspace set up for 'Edition' installation, I can at least double click the program monitor and see a still image.  But when I play the clip, audio only will play, the video stays frozen to the fixed image.

    fine.

    Around the same time that first stopped working, After Effects has stopped working as well, and my 64-bit version of Photoshop (the 32-bit version does not).  Illustrator and bridge both work as 64 bit versions.  After Effects opens my old projects but the program monitor is all white and I can't get the display to change.  Photoshop will import files, but the screen is grey.  Even if I start a new project and just trying to add text, nothing changes, I don't see anything.  Although I can import and image, make, make changes, and then save them, I have no idea what it looks like until I have save and reopen it with another program.

    Here, any help would be greatly appreciated.

  • Questions about video stabilization - iPhone 7 more

    Hi all

    Like most of you, I am an Apple enthusiast. I work as a videographer frelance. I use Apple products every day. I'm about to buy the new iPhone, but there are some issues that concern me. I've seen a few videos with the new iPhone 7 more, and it seems that video stabilization, its all just too bad. When the person walks, the camera is still struggling to stabilize images, and it gives a very poor video quality/eye. It seems that the video is allways glitching.

    I can't be the only one to notice this problem. Help, please! Do you know if its possible to disable? Which will probably solve this glitch.

    Best regards

    I have the same question. Today, I shot a lot of video footage and when I walk around with the camera I get a strobe effect. The video is useless. Does anyone else have this problem? It is with my iPhone 7.

  • Question about video memory on Satellite L30-113

    Hello

    I have a Satellite L30-113 and I managed to install a driver (I am learning how to in this forum, thx) for the video card, which allows me to change the size of the memory, what video card can be used. Configure the size of the (UMA) memory of 256 MB (including 128) properties, then in the properties of that memory for the graphics card is display 512?

    My question is that the size 512 memory is real? Video card really use this amount of memory or is unreal? If so is it better to go back to 128 (then in properties is 256), not to waste this memory for nothing.

    I know the les specifications specifications from the manufacturer, said 'max 256 memory hyper', but my question again: why in the properties I have the memory size: 512 MB?

    Thank you in advance, best regards.

    No, 512 MB is not true. The maximum size of video memory is 256 MB, but I do not know why your system shows 512 MB. If you set the video memory up to 256 MB performance will be no higher. Do not waste this memory to change anything back to 128 MB.
