Blackouts after 4-7 seconds of display UGA

same symptom; it pops up for a second, then checks out.

three displaylink services running

turning display on and off thru resolutions generates another brief visit

still looking for extra Plugable hardware device here.

I actually only need one to run...digging here

[bawjkt]

and symptoms are the same, probably indicating the original hardware device is fine...

may have to try this with another display also available here....

any more thoughts on software solution? Unusual that I have another identical device, that behaves in the same way...makes me think it's not Plugable hardware problem.

on to test with another external monitor...


...developing story

Connected to a much larger Samsung LED TV.

Both Plugables perform without issues. Come up and stay up.

Also using clone laptop as I mentioned ... original laptop probably performs as well. Thinking this is an interface problem from a 2007 Viewsonic.

We removed the DVI interface from that one monitor from the picture and replaced it with another device (a Samsung 32" via HDMI) and the Plugables (both of them) run flawlessly.

There's no software problem. There's no hardware problem from laptop out thru Plugable to device. Probably Viewsonic DVI port has had it. Will test later to confirm.

Basking in the glow of the Samsung 32" which fits on my main desk, I'm thinking I may keep it that way. Rock solid and looks great albeit 720P.

So now I'm thinking Plugable #2 now drives 2007 22" Viewsonic via VGA and see how that goes. Because I want it back and I think I can get it, via VGA.

I have two of these display adapters as it is. From 2011. Just use *both*.

Hop all of your tickets go as well as this one did. There's nothing wrong with my USB display adapters. The monster Samsung looks gorgeous and rock-solid. With both (relatively ancient) USB display adapters here - they are fine. There are no findings here saying they are failing. Both work.

I'll drill down on the Viewsonic DVI port later - or maybe right now actually...like the panorama.

Old Viewsonic does not connect via HDMI via DVI to Plugable.

Also does not connect via VGA direct to Plugable.

However, old Viewsonic *does* connect to laptop via HDMI-out from laptop connected to DVI-HDMI converter cable direct to DVI port on Viewsonic.

But old Viewsonic is still in the game as direct from laptop HDMI-out to DVI-in does work.

Laptop straight to Viewsonic via VGA also does not work.

But laptop out HDMI to DVI-in on Viewsonic 22" VGA works.
And, Viewsonic 28" direct from laptop via VGA to monitor also works concurrently.

So with

HDMI-out from laptop serving a converter cable direct to DVI on 22" 1680x1050 Viewsonic,

and VGA-out on laptop serving Viewsonic 28" 1920x1200,

plus one Plugable serving the 32" Samsung at 720P I get...

three large displays out of a 2010 SU2100 laptop weaker than some Atoms today.

Did I try to enable the laptop display also? Of course. No go.

these are just one man's findings.
