I have an HP Spectre 15" (15-eb0053dx) plugged into a new plugable USB-C 4K via the USB C cable that was included. I’m trying to run just two external monitors (both HP 1920 x 1080). Although on the first day I was able to have monitors connected with one via the HDMI and one via the top Display port, the next time I used it it didn’t recognize the HDMI-connected screen.
They both work fine when plugged into the display ports, but I can’t get a signal from the HDMI output to either. I can get a picture from the laptop’s built-in HDMI to either monitor.
Is the issue just that the HDMI will only recognize a 4k screen? Am I missing any performance by using only the display ports? Although right now I’m only using these 2k screens, at some point I could envision upgrading to an external 4k screen and would like to know if the plugable will work with it.
Any help appreciated. Thanks.
