What would cause dark blurred display all modes?


I suspect the monitor is dying. Unless it is under warranty, you may need to replace it, as getting it fixed may cost more than a new one.

I need to connect a VGA dell monitor my Toshiba Laptop


HDMI is digital
VGA (the 15 pin connector) is analog.
If your connector has the digital to analog interface it should work, but likely it does not have that chip and thus will not work.

Your description of the problem tells me it may never work as you have it connected. Possibly it might be that the monitor is required to be powered on before the laptop is booted, but that only works in some cases.

I have also seen some work if a 2-step connector is used.
VGA to DVI connector, followed by DVI to HDMI connector.
DVI was the step toward digital that came before the HDMI standard was implemented and was only partially digital. DVI and VGA do not carry control signals nor audio. HDMI carries both those as well as the video.

YMMV but I think it would be cheaper and more efficient to actually purchase a monitor with a digital input (HDMI or DVI).
Without the digital/analog converter interface a digital output device (your laptop with HDMI out) can never operate an analog device (your Dell monitor with VGA input).

DVI ==> Digital Video Input
If your monitor has both DVI and VGA inputs,
and your PC's video-card has both DVI and VGA outputs,
then buy a DVI-to-DVI cable, and use it, for a better picture.
If your monitor has both DVI and VGA inputs,
and your PC's video-card only has VGA output,
then use a VGA-to-VGA cable.
Or, purchase a video-card with DVI output,
to replace the video-card with VGA output,
and then use a DVI-to-DVI cable.

    When dvi plug is used screen gets funny bright colored lines


    FIX for design fault of ASUS VW222u Problems with monitor using dvi while vga works fine.

    my ASUS VW222u had the same problem many are reporting after about 8 months
    with developing colored "noise" onscreen or dancing red pixels while using dvi but vga is fine.

    luckily my old man is an electronics engineer, rather than be without a monitor since vga still works fine we decided to have a look.

    we worked out the problem. note: this is a fix for the random picture noise problem while using dvi port.

    If monitor works ok with vga but dvi has noise then this fix should work for you.

    1.open monitor (will void warrenty)
    2.unplug all the the cables going to the power supply and dvi port assembly, undo two screws pull down and out you wil now be looking behind the dvi port and be holding a metal module that contails power supply and dvi- and vga port.

    3.you will notice a piece of brass foil joining the earths on your dvi and vga cable this is the problem creating an "earth loop" as both vga and dvi ports are earthed to the metal casing this extra earth is causing the problem introducing noise.

    3.carefully unwrap the brass foil from the two cables and seperate, insualte cables with electrical tape. (wrap around each one seperately they should now be indiivdual cables)

    4.you will notice a silver spring type peice of metal on the assembly that pushes against the
    main body of the unit when re-assembled. scratch the metal with a screwdriver where this peice pushes so you get a good connection when you reassemble it, do not touch as finger grease could screw up the connection. (this step is not vital just a good thing to do why your in there to make sure the the unit is properly earthed)

    4.re-assemble


    enjoy, fixed mine and was quite easy, take care with the plastic latches they are tight - ensure you remove all 5 screws, to see the fifth easily the monitor stand must be removed (two screws then stand slides out from rear of case)

    good luck

    Dvi to vga


    You will not benefit from the DVI input unless you have DVI output on your computer. The great advantage of DVI is that the picture is transferred in digital form all the way from your computer to the individual pixels on the monitor. If you only have VGA output on your computer then you will never get a better picture than by using a good quality VGA cable to link that to the VGA input on your monitor.

    The DVI plug is designed to carry both digital and analogue (VGA) signals on the various pins, so "adaptors" exist to allow a VGA monitor to attach to a DVI output on a computer. Monitors may also support VGA input from their corresponding DVI input sockets, but the picture quality will never be better than by using a good VGA cable because it is still not using the digital capability of the DVI interface. What's more, because you may need more adaptors and thinner conductors in the cable, you will probably achieve a marginally poorer picture than with VGA to VGA.

    When you next buy a PC or a new video card, get one with DVI to take advantage of your new monitor. In the meantime, your best bet is a quality VGA to VGA link.

    Sorry that's not what you were wanting to hear, but I hope it will help you avoid further frustration.

    The video card in the computer could be going bad too or the driver for the video has corrupted. Try reloading the video drivers in the PC first.
