We have had this PC hooked up to an older TCL Roku TV in the past and it worked just fine but on the new TV it will not display anything. I connect the HDMI cable to the TV, the TV pops up "We noticed you connected a new device to HDMI 1, what do you want to name it?" I select HDMI 1 as the name and it reverts to the home screen with HDMI 1 shown as a channel. I select the channel and the TV looks for the input, the PC flashes over to screen 2 showing on the monitor attached, and the TV returns "No signal, is it on?". Both the PC and TV realize the HDMI cable runs from one to the other but I can't get it to show the picture. I have ensured the software is updated. I have tried all 3 HDMI inputs on the TV, swapped the HDMI cable ends around and tried them again. I have changed the HDMI mode to Auto, 1.4 and 2.0 on all 6 setups. I have plugged the HDMI cable directly into a computer monitor and it works just fine, just not on the TV I am baffled on this one. Any help is greatly appreciated.
