    Good Day all,

    So I could use some advice.. Im really stuck on why I cant get it to do what I want and not sure what my best solution to solve..

    I have a laptop I am out putting video signal to a hdmi splitter box (which is power boosted to ensure no signal loss) to a monitor and to a tv (thats more monitor than tv) . The signal going to the 2nd monitor and tv arent 1080p which is what I would like it to be. I currently am using the thunderbolt output to the splitter and then hdmi to both monitor and tv.

    I do have the ability to output via HDMI but thought that thunderbolt was better (I could be wrong of course)..

    Im looking to have 1080p at both monitor and tv.

    Here is the hardware I am running

    ROG G750JH Laptop (http://tinyurl.com/y6f5or5v)
    (Minor changes to laptop, its running a 500gb ssd, 750 hd, and currently 16 gig of ram, but will be upgrading to 32 very soon)
    Splitter box (http://tinyurl.com/yylqsty7)

    Sorry, dont have the monitor / tv info at present, but will post that tonight if possible.

    So whats my best option to output 1080p? I would very much like to not have to spend a lot of money if possible. Just looking for advice and options at this point..

    First Name:
    To use each screen as a separate display (ie: two different monitors), you need to output from one port directly to each device (ie: one video port for each screen). You can use a splitter (sometimes), but you will get a mirrored output (ie: the same image on both screens). HDMI doesn't always work well or at all with splitters because the handshaking process and HDCP get broken. HDMI is meant to work one port to one device. When the devices are powered on, a handshaking process takes place where the devices talk to each other to determine what signals are supported and can be used. When you split the signal, the source device (ie: computer in this case), will often see conflicting or no information returned from the handshaking process and simply "default" to a low resolution.
