  1. Hi!

    I have PEXHDCAP capture device with HDMI, DVI-D/VGA and Component inputs.
    I can capture HDTV, by this way by converters also Composite video, S-Video.
    I capture also VGA, only component is unused.

    For capturing VGA I need VGA signal corrector, adjuster and booster 'cause VGA output of captured device is fatally weak.
    It has not enough intensity, brightness, contrast, saturation and also R,G,B are balancing.

    I was searching web for any device to adjust/correct/boost signal 'cause no one software solution makes it possible, but I found only precious devices which working with many signal types and no match with VGA, for example MK electronic CVX506...

    Can anybody of you recommend me any device which allows to correct/adjust/boost VGA signal brightness, saturation, contrast and Red, Green, Blue with option to turn off without signal loosing? Best if possible under 200 EUR...

    I need it connect to VGA output and from device to PEXHDCAP...
    I want also to write that PEXHDCAP was for me recommended by user of this forum... and I'm satisfied at all and this is reason why I'm asking again here.

    Many thanks for all advices, help, replies or comments.

    If I try to capture video and try to enhance image, results are high quality loss, looking like lower resolution and I tried many solutions that my OS is full of Video Editors...
    For this reason I search for device.

  4. For completion:
    I own AG Neovo X-22 LCD which allows perfectly correct HDMI/DVI-D/VGA/2CVBS/SVHS and here is the same VGA signal corrected by LCD:

    The closest thing that I could find to what you are looking for is called a VGA presentation processor or VGA presentation switcher/scaler, but they are expensive items and most have been discontinued by the manufacturer. You might be able to find a used model from Kramer Electronics on eBay that is being sold for a reasonable price.

  6. Hi!

    I was searching eBay, but must to say that no one was that I need, also found prices ~200 GBP... but really I need not switcher, not scaler...
    I need device which works with picture properties written in this thread above...
