Q: Can you help me with a DVI dual-monitor setup?

I have gone through a few weeks of effort with this and seeking a

definitive solution… I have a Mini i7 - 2012 model.  Two identical

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

screens.  One monitor, near proximity to the Mini..about 1-2 feet..

The other about a 25 foot distance. 

This worked with an HDMI>DVI adapter to a Tripp Lite DVI splitter

for over a year…then became intermittent.  I tried a different splitter,

an Auralek - it worked ok about a week, then stopped.  Seems like

the splitters stop sending whatever wake signal is needed after a

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

no video signal upon powering back up.    Have tested all cables,

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

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

BTW this works ok using an MiniDisplayPort>VGA splitter but i want

DVI resolution.

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

that is relatively bulletproof to accomplish this…?  I have found one

other device by Sewell that is basically another powered splitter --

which someone has said worked 'better' than the Tripp Lite… 

There appears on diagnostic testing there's nothing wrong with the

HDMI port on the Mini. Both of the monitors work fine individually

when connected directly to the DVI port btw. 

Hope somebody can help.

THANKS!
