Decided that I wanted a TV mirroring one of my computer monitors for couch gaming. Bought a used TV, turns out it's not full HD (it's 1360 * 768). If I just connect up a HDMI splitter to it and my HD monitor supposedly it would downscale the monitor to keep the TV happy.



So, a few days pass and I decide to just up and buy a HDMI splitter and plug it in and see what happens. Turns out, they were right, the TV is happy and the monitor now 768p.

I tested to just take a 1080p picture and downscale it to 768 and it's good enough that I would prefere it to have my monitor stay 1080p.

So, how would you go about this? I found a HDMI Downscaler, but I'd rather not spend that much money. Is there any other way I could go about this?

Okay, found a better way. Plugged the TV into my PC's motherboard HDMI slot so my PC just thinks of it as 4 monitors (3 full HD, 1 Half HD), used Intel's "HD Graphics Control Panel" to change the monitor to fake being full HD so I could mirror my monitor onto it.

Now a different problem has appeared, the picture is too far up, about 1cm is above the pixels of the TV and there's a 1 cm black bar at the bottom. pic

Going into settings on the TV to move the screen doesn't work, unless I use it's zoom feature, but then I can only move it down enough to cover the same area as earlier, no more.

So, I got it to work more like how I want to, but it's still broken :(

The TV does NOT support 1080p input, but I think the Intel graphics fakes a 1080i, even though the support page for the TV says (I think) it doesn't support it.

Edit: nope, I read wrong. The TV (LG 42LB1R-ZE if you're interested) does support 1080i, but I needed to install Intel's program to change to it.

So, presumably, there's something going wrong in the mirroring a 1080p and a 1080i monitor.

Okay found a "solution" or "temporary work-around".
If I changed the input to HDMI (DTV) instead of HDMI (PC) I was allowed to manually change the settings for height placement of the input. HDMI (DTV) has the problem of being constantly zoomed in and I was unable to zoom out, but if I changed it's height placement value and then changed back to HDMI (PC) it remembered it's placement from the HDMI (DTV) settings.

I have not yet tried turning it off and back on and see what demons that spring up when I do, but for now it's fixed.

Also;
I found out how to go into the Service Menu, but none of the 6 standard LG passwords worked for me, presumably the person I bought the TV from had changed it. So if anybody happens to know how to factory reset an LG 42LB1R-ZE without needing to reach the service menu, I'd be greatful to know.
