LG 34UM95-P User question.

[Norrie83]

Hi guys

I am now on my second LG 34UM95-P I bought it to go with my trash can Mac Pro and PC.

The display is awesome for the audio editing / recording work I do but I think I may have a issue with the USB ports on the monitor and would like to ask a massive favour and see if anyone here could test something for me ?

My issue is that I have the display connected over thunder bolt to the Mac Pro and then I put a USB self powered drive or SSD in a enclosure connected to the USB 3 port.

I can then see the drive but can't use it it will actually crash my Mac Pro and I need to hot plug the drives to get the mac running again

I have spoken with Over Clockers who I have bought it form and they are having the same issue on PC

I can use it if I use a USB data + power cable and connect to 2 ports on the monitor then the drives work fine.

Spoke with LG t and they told me that there is no known issues doing what I describe ( i am now waiting to hear back from them again since this is the 3rd monitor I know of with this issue )

Has any one else ran into this problem or could perhaps please test it with a few USB 3 self powered drives?

I've tried Samsung evo SSD's in various enclosures OCZ vertex 460 drives in various enclosures , WD my passports , WD elements , oand a load of other various drives but all the same issue unless they are mains powered or I use the double cable.

Pen drives seem to work fine as do keyboard or mouse.

Would really appreciate if anyone else could test there ports with a few drives?

Thanks to all for any help.

Oh and for anyone interested in seeing the monitor in my setup it is here

Sounds like you're simply trying to pull too much power from the single usb port rather than a fault, why not use a powered hub?

My 95-P (which I rma'd for other reasons) was fine for pen drives but I didn't try a hdd. Pg 17 of the manual recommends using powered drives though.

I agree with RichL, everything I've plugged in has worked including a 360 wired controller.
My Powered HDD's also work fine, so it seems the port can't supply enough power.

I wouldn't recommend constantly trying to do what you're trying, I remember killing a USB port on my 2009 Mac Pro.

Thanks for the replys guys.

I spoke with LG and they told me that it should have enough power from the USB 3 port on it and I should RMA it due to it being a fault.

Although I do have my work around so it's not a major issue the tecs at OC also say it should work but it is crashing there test rig when a drive is connected.

Hmm must be a faulty one then, although unless you can get a guaranteed 1 week replacement I'd be iffy dropping work to replace it.

One of the reasons I tend to keep my older monitors around for ages.

They have stock for a replacement.... only problem is this is my second one and it's the same on the one OC are testing yet LG continue to say it should be fine.
I am perhaps wondering if there is a bad batch.

can any one test this please ?
