I recently bought a new Asus Zenbook (Ultrabook). Then, in order to enable quick set up with all my peripherals when I’m working in the office, I purchased your Plugable UD-160-A 2.0 from Amazon. When connected to the Plugable docking station, performance seems to decline in certain respects. Plugged into the docking station are: an HP w19b LCD Monitor (via a VGA cable into the VGA/DVI adapter provided), an HP printer/fax/scanner, a backup drive (WD My Passport), headphones, a set of external speakers, and am iPhone syncing cable.
The problems I’m experiencing include:
When listening to music or a streaming video, sound through the headphones plugged into the docking station periodically becomes garbled - but only after 3 or 4 minutes of use. This effect seems to cycle in and out ever few minutes and ceases - at least temporarily - when I go to Sounds (in Control Panel) and select a different output device as default.
When I move the cursor or page up or down on webpages, the image on my external monitor (HP w19h) pulses in and out of focus (but not on the notebook display). This effect ceases for some reason when I enter Control Panel > Appearance > Display > Resolution > Advanced Settings and make adjustments to either Refresh Rate or Color (True-32 bit; or High 16 bit). Incidentally, settings for use the external monitor include: DISPLAY: “1 | 2 Mulitple Monitors”; and Mulitple Displays: “Duplicate These Displays”.
Sometimes the external HP monitor freezes or slows down and just does not keep up with my notebook PC’s monitor. Especially when watching streaming video. Perhaps its too much for the docking station to process video and audio in this situation - OR perhaps my Asus Zenbook isn’t performing well. I don’t know how to diagnose which.
Can you help ?
