Summary: I ordered a typical HP Photo frame and received this Philips instead. Seemed okay at first and I didn't complain since this was twice as expensive. However, this completely stopped working after 8 months. It has a 1 year warranty, but my receipt says HP, so no warranty for me. Must throw it away and buy another one, but it won't be a Philips.
Summary: I can echo most of the other disparaging comments. The device works with Windows 7 x64, but you have to install the software from the included disk first, which also installs drivers at that time, before you connect it to your USB port. And if you change modes, you will most likely have to shut down the Philips app and unplug the USB cable before you can use the thing with your computer again. It has 2GB of memory onboard, plenty for photos.
Summary: Just a weird feeling about this one. Seemed like it had been opened before. Like others are saying on here. Box was weak. Packaging was crinkled. Works okay. Not what I would expect, but it wasn't that expensive.
Summary: I bought the PSG4080P because of the sub-display (monitor over USB) support. Well, the display technically works and I am even able to get it to work on windows 7/x64, however when the device is used as a sub-display (or even plugged in via usb) Windows Aero effects cease to work until I log off/reboot. The video driver doesn't cleanly restore the functionality. The display is nice and crisp, surprisingly, though.
Summary: Works minimally as an extended display but lots of bugs and looks like no driver development underway. Probably will just use it to display photos. For the price I got it that's fine, but definitely not worth the retail. For the guy that said it doesn't work in Win7 64bit, I got it to work but it's a big pain. You need to follow a certain sequence, first have it unplugged from USB, then start the App on PC, then plug USB in.
Summary: Please let me save all of your the horror of this product. I had originally purchased this so I can use it as a desktop signage device, showing videos and slide shows. The quality is sub-subpar. I had better photo quality on my cell phone from 2000. Video plays back with so many artifacts that it's unbearable to watch. I wish I could link you to photos of the horrendous quality of video playback and image display.
