Keyboard Stops working

[RM14]

I just upgraded from a dual monitor (HDMI connection) to a single Samsung CRG9 49" curved monitor (HDMI). Ever since doing this, my bluetooth keyboard randomly just stops responding and sometimes takes several minutes to return. During this time if I reconnect the old monitor, keyboard works just fine. Have ensured that I have all the current drivers installed on both the NUC and monitor. Just dumbfounded as how a different HDMI connection could effect the keyboard working????

Does this monitor by any chance also have a USB connection to the PC? USB 3 utilizes 2.4GHz signalling on its cables and poorly shielded cables (become antennas and) can interfere with Bluetooth and 2.5GHz Wireless communications. All you can do in this case is get better USB cables.

Thanks for the reply. No, USB connection from the NUC to the monitor. Another weird issue (that might be resolution related) is the monitor will not wake up from sleep or on reboot unless I follow the exact steps below:

1. Turn off NUC

2. Turn off monitor and unplug HDMI cable from NUC.

3. Turn NUC back on and let it boot up completely.

4, Plug HDMI cable into NUC. 

5. Power on Monitor.

If those steps are not followed EXACTLY, I get no display on the monitor if it goes to sleep or I have to reboot. Current resolution setting is 5120 x 1440 which is the recommended resolution....

Just odd behavior....
