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?

Well the cheapest solution is probably just to switch to 768p when you want to use the TV.

Did your computer automatically switch to 768p when you plugged the TV in? You could also try forcing the output to 1080p and see if the TV shows anything. It's not likely, but hey that's all I can come up with.

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.

Weird about the black bar thing. I think this is just one of those situations where you just gotta try every combination and then pick whatever works best for you.

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.

Nice!

I'm clueless about the factory reset though. Maybe you could... contact LG support (heh heh).
