Can you help me with a configuration of dual monitor DVI?

I went through a few weeks of effort with it and seeking a

final solution... I have an i7 Mini - 2012 model.  Two identical

Acer S241HL LED monitors.  I need the same video display DVI on both

screens.  A single monitor, close proximity to the Mini... about 1-2 feet...

The other over a distance of 25 feet.

It worked with a HDMI > DVI adapter to a Tripp Lite DVI splitter

For more than a year... then became intermittent.  I tried a different separator,

an Auralek - it worked fine about a week and then stopped.  Looks like

dispatchers to stop sending any signal wake-up is necessary after a

period of time where the computer or monitors have been turned off and then

No video signal on the power of return.    Have tested all cables,

recycled, reset everything that can be reset etc... with Mini and

monitors...  Have had the same problem using Thunderbolt > DVI adapter.

BTW, this works ok using a MiniDisplayPort > splitter VGA, but I want to

Resolution DVI.

Bottom line, is there a known reliable separator or any other approach

It is relatively bulletproof to achieve...?  I found a

another device by Sewell who is basically a different dispatcher amplified-

who says someone worked "better" than the Tripp Lite...

It appears on diagnostic tests, there is nothing wrong with the

On the Mini HDMI port. Both monitors work fine individually

When it is connected directly to the port DVI btw.

I hope someone can help.

Thank you!

VGA must have resolutions more than DVI, what ground had VGA?

  • My mind is wiped out. I'll put up pages in Photoshop 9.0 to be then placed in InDesign 4.0 for professional printing. Can you help me configure the proper color settings, and what PDF preset to use. And output parameters, etc. Thanx.

    My mind is wiped out. I'll implement the color pages in Photoshop 9.0 to be then placed in InDesign 4.0 for commercial printing in book form. Can you help me with the settings of color in Photoshop, that is to incorporate the color profile; convert in space work, Adobe RGB, etc. and which PDF preset to use, i.e. printing, PDF / X - 1 or 3, etc. Also, what I have to select the output settings such as the conversion of colors with the Destination or the printer deals with that. I know I asked a lot, so thanks in advance for any input or advice.

    Best regards, ScottyB34

    What are the settings of your printer wants? Some may deal with sRGB some want Adobe RGB Ctrl/Cmd-Shift-k in Photoshop, then choose North Amercian prepress 2

    He'll take care of the tags for you, or if sRGB is important, Norh American General Purpose 2.

    Here is a summary of the settings PDF and their meaning:

    When you are ready to create a PDF file from an application such as Illustrator or InDesign Adobe, we give you a list of the predefined PDF settings from which to choose. Well how do you decide which is the right choice? Well, let me explain what they do.

    Let's start with the smallest file size and the name of the type of the story. It is compatible with Acrobat 6, which means that anyone who has Reader or Acrobat 6 or above will be able to open the file. Now it converts everything in sRGB color which is a common space for color monitor.

    All RGB is truncated to sRGB, CMYK and spot colors also. So that means if you have a job to print, you can see some color shifts in this outgoing PDF. You must decide whether it is acceptable. He can't stand live transparency, not flattened. It downsize image content to 100 pixels per inch and this is part of how she made a reduced file size. It also uses aggressive JPEG compression of poor quality on the content of the image. So, you can see some of these rectangular JPEG artifacts.

    But it is how it gives you a reduced file size, and results are appropriate to be posted online or attached to an email.

    High quality printing has compatibility with Acrobat 5 and above. There is no color conversion. RGB RGB stays, rest spot, stays of CMYK CMYK spot and it supports live, not flattened transparency. It does not perform some downsampling to 300 pixels per inch. So, for example, if you placed an image which was 300 ppi and then set to scale up to 50 percent there actually a res then 600 pixels per inch.

    Well, this process would take half out these pixels. Therefore, it can create larger files but that makes it suitable for in the House of printing or sending Let's say a remote office if they want to print we tell cells leaves, or brochures, or something like. It's beautiful out on an internal printer.

    Print quality and high quality printing have similar names, so this may be a bit confusing, but print quality has compatibility with Acrobat 5 or higher. It converts the content of RGB to CMYK destination values according to what you specify as the destination.

    It is usually SWOP, S-W-O-p. It supports live, not flattened transparency. It performs the subsampling bicubic to 300 pixels per inch and because that it keeps at least 300 pixels per inch, which means that it can create some large files, but it is suitable for professional printing.

    Then we start to get into the presets named 'X '. 'X' is now for Exchange. They agree on specifications and the idea is to have a set of specifications if a PDF file is compliant to these specifications, we know it's going to be printable.

    We know that imaging devices are going to treat them properly. So this goes back to 2001, and which can seem a bit old, but bear with me. PDF/X-1 has a compatibility with Acrobat 4. I know, it sounds old. It converts RGB to CMYK content, it keeps the content of good tones. It flattens transparency. Downsize it at 300 pixels per inch. It can large enough crat files if you have large size images in your project and that it is suitable for professional printing.

    The idea behind X-1 is if you send a PDF file to an unknown printer, you do not know what are their capabilities, you send abroad, it will be able to be photographed on any device. No matter the age, it is, they can print. Over the years, the concepts of Exchange became more sophisticated the workflow and devices become more sophisticated.

    SP PDF / X-3: 2002, remains compatible with Acrobat 4 and that means that it flattens transparency, but it does not perform any color conversion.

    This means that it maintains RGB content, place remains in place, rest of CMYK CMYK. He still performed bicubic downsampling at 300 pixels per inch, and therefore, it can create large files. But this is suitable for commercial printing, if the printer signals you that it is present RGB content is correct.

    PDF / X-4: 2008 is compatible with Acrobat 7 and later. See, we're getting more modern. No color conversion. RGB RGB stays, stays CMYK CMYK, spot rest spot and it supports live, not flattened transparency.

    He still performs bicubic downsampling. Therefore, it can create large files because it maintains the pieces of the image to 300 pixels per inch or higher and it is suitable for commercial printing, as long as the printer tells you that RGB content is not serious and dynamic transparency is acceptable. Some older workflow does not support dynamic transparency, or they treat well, and that's why always ask. It is a special case in Illustrator, something called default Illustrator. Its compatibility is Acrobat 6 or higher.

    It does not perform the color conversion, everything continues like this. It supports transparency live, not flattened, and it also contains the original, editable Illustrator file in the PDF file. It preserves layers and it may be return, can be reopened safely in Illustrator and it's really the only PDF format you can do with safely. But it can create larger files, because you sort of two files for the price of one, they sometimes get huge.

    So what predefined PDF is Right For You? Well, if you want to send for printing, the first thing you should do is to ask your printer how they want the created PDF.

    They should be able to give you the plug for the creation of the PDF file. They may be able to give you job options files you can simply import and use as your preset target. But if it's a stranger the printer or the printer for some reason any said, well, I don't know, just make a PDF and this happens, well, choose the lowest common denominator to the PDF/X-1 test. Anyone can image that. If it is a more modern printer and up to date, especially if you send it to someone who uses digital presses, PDF/X-4 should be safe.

    I always go back to point one, ask the printer. If you send it as an attachment or you're going to post online, well, smaller size of file is a pretty clear choice. But remember this, you can start with one of these predefined parameters, and you can always edit it to customize your specific needs. So get to know the presets, understand the destiny of the PDF you create, and then make the best PDF that you can.

    You are prompted to enter the password for your private key when sending a signed message. You get the password prompt at all?
