Universal Adapter not working with VGA Switcher

I purchased a VGA switcher from monoprice and i received an AC adapter which is 120V and now i'm in the Middle east and the Universal adapter i purchased turns the Vga switcher on but the screen is black but when i use the original adapter with a step down transformer it works great.

P.S i cant use the original adapter without a step down transformer in the middle east because here its 240V not 120V plugging the adapter would burn it.

Any tips? Thanks in advance. PHOTOS OF EACH:

Question about VGA to DVI

Okay i have an old CRT monitor with only VGA. On my video card (x850Pro, yes old too) there is VGA and DVI, is there any advantage in using the VGA-to-DVI adapter that came with the video card or is it the same thing as going VGA-to-VGA? I assume there is an extra step that VGA-to-DVI adapter has to do to make the analog signal to digital, is that a disadvantage? Basically VGA-to-VGA or VGA-to-DVI.

Thank you.

 

Universal Adapter not working with VGA Switcher

It looks like your original adapter output is 24 watts and the universal is 18 watts.... Check the label on the device for power requirements or check your polarity on the universal adapter (that may be reversed)

There should be a polarity diagram on the device near the input plug.
