I have a DX80. We are using this a a monitor/phone. The issue right now is this:
The PC output is DVI and I have an adapter on the DX80. The adapter is HDMI to DVI to connect with the PC. It works fine but if your gone for a few minutes the display goes dark. When you try to refresh the display never comes back on. I can still see everything else on the DX but not the display from the PC. Restarting the unit seems to work. Any suggestions?
Can you confirm it works fine to a PC that does have HDMI (HDMI to HDMI)?
I've found actual HDMI to DVI cables work better than adapters. I'd order one and give it a try.
I have the same issue, but I have jsut a driect HDMI connection from my PC to the DX80. This only happens with my laptop (other laptops do not have the issue). ALso, the issue happens every time I hang up a call.
Is your DX80 software up to date? What version are you running?
Is the display driver for your laptop up to date? What brand/model laptop is it?
Given that other devices work fine when connected to the DX80, and it's only your laptop, it soulds very much like an issue with the drivers on your device, or a hardware issue with your PC - or a dockings station problem if you're using one of those, which I suspect as there are very few laptops I know of that have a DVI port on them.
There are a few other posts on the internets with people complaining about issues with external monitors and the P50 - supposedly fixed with a BIOS update.
See Lenovo P50 Laptops - Video/display issues with external monitors as one example.
