Q: Issue- no video -DVI dual splitter i7-HDMI port>DVI
What am I missing here?
I have an i7 2.3g -late2012 Mini. 10.8.5. in a studio where i feed a dual display
using a video splitter by - first, Tripp Lite, now an Aluratek -DVI 2-port video splitter (powered
units).
Followed all proper sequence in start-up, device worked for maybe a week and a half.
Walked away and returned after maybe 48 hours i.e. Friday to Monday. Computer was running in
sleep mode… On wake attempt, No monitor video signal recognized. Powerd off/on, no change.
Reset PRAM and disconnected/reconnected Mini Power after 30 secs… tried reconnect splitter/monitors…
sequence….still no resolution of video signal to monitors. Indicators on splitter show signal from the i7,
and connectivity to the monitors. I'm ruling that device out as the fault.
Am following all proper mfgr procedure as far as the splitter just as if new out-of-box in reconnecting
powering it up - getting nothing. Odd thing is, I had identical issue with the Tripp Lite - which is why i
bought this Aluratek splitter to replace it. Now, same issue.
When first connected to same monitors, it worked fine right out of the box.
Now the same issue as the other splitter. Changed out two different HDMI>DVI
cables. ALL cables. No change.
Connecting either of the monitors directly TO the HDMI port on Mini-- display works fine.
Tried MiniDisplay port to splitter. didn't work...
What could conflict in the OS - something making these monitors sleep, something system-wise
that's disrupting this process? Even pulled all other connections (external USB port stuff) and it
didn't resolve it.
It's too coincidental for two splitters to fail with this same issue - seems to point to something with the
Mac. Meantime, no dual-display til i can figure it out.
Any help greatly appreciated -
Thanks,
Mike
