HDMI, are they all the same power?

[mallorcaben]

I have just purchased a ASUS VivoBook 15 F515JA to replace my old Lenovo for my work.
I work as a Karaoke host and DJ in a bar.
The bar has a multiple TV setup connected by long HDMI cables. Not the best solution but as the boss says “it works”
I connected the HDMI to my new laptop and no signal. It was fine with my old laptop and its fine on my new laptop connected to one TV but not to the multiple system.
My boss is not going to change his HDMI system.
My question really is: does a budget laptop like this have a lesser power HDMI output?

It is not the HDMI port itself it is the graphics solution that supplies it, your new notebook does not have a dedicated GPU only on die video that is incorporated into the CPU which in turn relies on the system memory for support.

The CPU in your new computer is capable of supporting three displays but you may need to have more than the soldered into place 4GB of RAM that the ASUS Vivo Book 15 F515JA ships with.

What is the full model name or number of the old Lenovo.

Is there only 4GB of RAM in the notebook.

Yeah, I have come to this conclusion also.
I realise I need a laptop with a separate gfx card built in.
My Lenovo is a Z580
The gfx is a GeForce GT 630M
It’s also got an i7 and 8gb ram.
I’ve returned the Asus. I’m going to make do with the Lenovo for a while longer until I can afford a modern equivalent.

That on it`s own makes all the difference as it is not reliant on any of your 8GB of system memory.

Makes sense and we wish you better fortune with any replacement.

Thanks for the follow up (y)
