DisplayPort annoyances

[davidhbrown]

So, DP++ seems to be the one video connector to rule them all. Unfortunately, I have found a couple of annoyances using it.

1. Volume On Screen Display gone wild?

When I am running audio to my monitor (a Dell U2410) over DisplayPort, Lenovo's On Screen Display for the volume level appears any time the computer plays back any sound. Did you know that both Windows Explorer and Internet Explorer play very quiet little sounds every time you change folders/pages?

Turning off On Screen Display is hidden in the Screen Resolution Control Panel... click the Advanced link and look for the "On Screen Display" tab.


2. Sleep = disconnect?

This may be specific to my monitor (which I'm not giving up with its 10-bit IPS joy), but when it's put into a low-power state for power saving, the system seems to think it's been disconnected and collapses all my windows onto the laptop's screen.

The screen comes back when I log back in, but any windows that had been larger than the FHD 1920x1080 resolution of the notebook screen aren't any more.


If I'm just doing something wrong, please let me know. Meanwhile, I think I'm just going to go back to DVI + analog audio.

System: Lenovo W520 / Optimus (Quadro 2000) / FHD (1920x1080, 6-bit)
Dock: MiniDock Plus Series 3
Monitor: Dell U2410

OT, but can you run benchmarks for the 2000m?
(3dmark06, whatever else)

curious how it fares vs the GTS450 it's based on, or if it's even worth the extra cash.

Hearing about things like this and the B2 stepping board issue that I'm waiting on Lenovo to give me a straight answer on, I'm about ready to take my mSATA card and stuff it into my Dell Axim x51v PDA (just kidding, it would only fit if I used an imaginary shoehorn and hired leprechauns to perform the labor), get a refund on my W520 and go buy a MBP.

The fun is going away...

Not really into that, but NotebookCheck has one now with the same CPU even. Score was 11.6k or so on the 3DMark '06 benchmark; there are a bunch of others on that page, probably all from one user.

Do You have found a solution for the "sleep = disconnect" issue? I'm having it with a newely bought U2410 thats connected to a X201i in a dock via DisplayPort. Every time the computer goes to sleep or hibernates, the monitor stays ON telling me nothings connected, for several minutes, until it goes to sleep too. Very annoying!
