Trouble Connecting Asus n56vz via HDMI

Hey there,

I've been looking around trying to find solutions online but can't seem to find people with my exact same problem so I figured I'd post it here.

Got the n56vz. Love it. But I can't seem to get it to detect and put an image on my Panasonic Plasma p42s2 (42" inch plasma, 1080p). I'm using an HDMI cable, and had no problems connecting my TV to my older Sony notebook 1600x900.

At first I thought it might be because the Asus' resolution isn't supported, but lowering it down didn't work at all. Now I think it's a problem with the fact that my Asus also has a VGA and has both the Intel Integrated 4000 and the discrete 650M graphics.


Basically, when I connect the two, the screen on my Asus goes black and nothing happens on the TV. I can get the screen on the Asus back by doing Computer Only via Windows + P. Duplicating gives a couple flashes then reverts back to the last setting, extend extends the desktop on my laptop to the point where I can't see the menu options (and then reverts back in 15 seconds), but nothing happens to the TV. The TV doesn't do anything in Projector Only mode.

So when I enter the screen resolution settings, the TV is my 2nd Display and is called a "Generic non-PNP monitor," which I'm guessing the issue is. I also checked the BIOS and couldn't find anything to enable HDMI on my Asus but I don't think that's the problem. When I try to change something via the Nvidia Control Panel or the Integrated Graphics software the TV Display isn't even detected, even if I use the Nvidia aggressive TV Display Roaming thing.


Any insight would be great.

 

Seems strange that it shouldn't be detected by model in some way. Not that it shouldn't work to force a particular resolution, or specify something yourself. But since that tv is reasonably new, it should have something identifying itself..

Does the TV have two hdmi ports? Tried using both?

 

It's pretty weird, actually. I have 3 HDMI ports, and after trying all three of them, using the third one (port on the side rather than the other two ports which are from the back of the TV) works and identifies it as a Panasonic TV. Everything works fine, including sound.

The only problem is that the edges of the display on the TV are cut. Any idea how to fix this?

EDIT: So... apparently I just learned that if I connect the HDMI cord to my laptop first, and THEN to my TV, it does something which helps with the identifying process, and the laptop correctly identifies it as a Panasonic TV.

 

As far as some of the screen being cut, right click your desktop and go to your NVIDIA control panel and look for "Adjust desktop size and position" under "Display" and see if those settings give you the results you're looking for. Also, I make sure when I connect my TV via HDMI that I press FN+F8 to enable the LCD/HDMI or just the LCD or just the HDMI.

 

Yeah. Props to Panasonic. That sounded.. logical and straightforward. :/ ..I think what happens is that they have a different loop (second circuit board) on one of the hdmi-ports..

The edges comes from the tv having a different pixel resolution than the actual input. Have the same on my 1920x1200 monitor - two options: change the scaling on the TV, or specify scaling in the nvidia settings.

 

Thanks for the help, but I FINALLY got it to work the way I wanted to.


For some reason, since it first started detecting it from the third HDMI port, I managed to move it back to the second port (where I wanted it) and have it detect properly from there. Sometimes it still reads it as Generic non-PNP, but usually now I can just unplug and replug it from my laptop and get it to read well.


Lulz, thanks for the help. I actually didn't have the "Adjust Desktop size and portion" option for the first couple times, but after restarting my laptop I found it. I actually didn't need to adjust that size at all -- I just had to switch the HD size on my Panasonic menu to HD 2 from HD 1 (weird).

Nipsen, thanks for your help, but it wasn't a resolution issue (I already tried it). The TV is set to the same resolution and I wasn't able to change it.


Either way, finally solved it, although I'm still not quite sure what I did to get the laptop to start identifying the TV properly.


Also, Nipsen, off-topic but did the keys on your keyboard for your n56vz start getting dirty and "faded" looking pretty quickly?

 

lol ..that sounded even more logical than the first one.

And yeah, the plastic they use on the keys gather fingerprints pretty easily. Sweat and salt and so on, and they'll become grey very fast. I kind of like the heft, though. That you're not playing piano, like on a macbook, but that it's more like tapping on a keyboard.

 

Haha. It happens, I guess.


And yeah, first week with the laptop and im starting to notice the graying, so it's bothering me a bit. Does it just keep graying out over and over or is there a point where it doesn't gray out as much and still looks good?

I like the heft as well. It's also pretty quiet -- my first impression was that it gave me the macbook keyboard cover quietness without the keyboard cover.

 

Just don't eat so many cheetos while typing. No, I don't know.. damp cloth, etc? The surface does collect dirt very easily, though. So it looks a lot nicer if you only wipe the top of the keys, and leave the rest with that nice, cozy worn dirt-texture.
