My tv hdmi ports connedts to only lg products now i was able to connect my playstation to my lg tv and watch 3d movies but last couple days tv says connecting and no signal playstation works with hdmi cable on my oldest lg tv but not with my new 3d lg5600 tv plus i cant conect my loptop to my lg5600 with hdmi but i will connect with my oldest lg tv plus when i connect my lg 3d blueray player to my lg5600 3d tv 3d warning popups that i have to connect to 3d display i did connect already someting wierd going on with my lg5600 tv

the tv automaticly determines if it should go to 3D mode as long as the DVD player or say like PS3 or PS4 is connected to HDMI (yes those two game consoles will support HD Blueray 3D and DVD 3D movies) if the TV isnt displaying 3D look into the video settings of your TV to enable that ability also your TV will come with 3D glasses if the TV supports 3D

I don't think the system is compatible with the TV it can't read the pad through the HDMI port only the RGB port.

Sounds like your blue ray player is defective

You need to make sure the TV is set to the same input that you are plugging into. This is done in the video menu.

Your tv is a 2008 model, legacy 3d tv and requires a lot more than a current 3d HDTV does to view 3d. Today with a current 3d HDTV, Normally you only need a 3d source like a 3d Bluray movie and 3d glasses from Samsung and a HDMI cable connection from bluray player to HDTV. See below for your TV. You need a PC and IR emitter and Samsung 3d glasses plus user selected options on the tv.
Samsung 3-D Ready HDTV How do Samsung 3-D Ready HDTVs work?
Samsung 3-D Ready HDTVs are enabled by Digital Light Processing (DLP(R)) or Plasma Display Panel (PDP) engines that are capable of very fast refresh rates (120Hz). The inherent speed of these display technologies enables high quality stereoscopic 3-D by alternatively displaying left and right eye images. The display is synchronised with 3-D shutter glasses to provide the observer with a vivid perception of depth.
How do I connect my PC to a Samsung 3-D Ready HDTV?
The DVI output from the PC's graphics card must be connected to the TV's 3-D compatible HDMI port using a DVI-to-HDMI cable (or a HDMI cable plus a DVI to HDMI adaptor).
Alternatively, some newer graphics cards have a HDMI port instead of a DVI port. In this case, simply use a HDMI cable to connect the PC directly to the TV.
On all models, the 3-D compatible HDMI port is identified by the letters "DVI". (eg, "HDMI 3/DVI IN" or "HDMI 1/DVI IN")
What other equipment do I need to enjoy 3-D on my 3-D Ready HDTV?

• Windows PC with DVI output
• Compatible 3-D Shutter glasses and IR emitter with VESA compatible sync connector

How do I connect the IR emitter to the 3-D TV to support wireless 3-D shutter glasses?
The IR emitter should be connected to the "3D SYNC OUT" socket. The emitter should be placed on top of the TV with the LEDs facing towards the room. How do I turn the TV into 3-D mode?
Ensure that the TV source is set to "HDMI 3/DVI" (or "HDMI 1/DVI" for 720p models).
Plasma HDTVs Press the Tools button and select 3D Effect. Update from Off to Mode1.

ideally you would simply add an hdmi source from each device to the surround receiver and send the output to the tv but im thinking your amp may be short on inputs from all devices and if indeed it was this simple you wouldnt be here seeking this info also note you may be able to use the output on the set to gain another signal tranfer but note there can be compatability issues on some sets whether they will decode hdmi in and rca out or optical out like i said some sets ok :) i wish you luck and wishin i had this all in front of me so i could be a greater help any q's drop me a comment here ok :)

3D in tv technology wright now are in it infincy.Not worth the money to buy the 3D LED tv and it 3D external devices.Right now are very limited in productions in movies in 3D world or 3D movies for tv or transfer from 3D movies from the movies theather Big Screen.Right now,just best to watch 3D movies in the theather Big Screen.Stick to a 2 dementional LCD tv screen for at lest another 5 years,before there are 3D tvs and movies,will make a difference in ur lives.

You will need a 3D-capable or 3D Ready tv. The difference is the 3D-capable tv will require you to buy a piece of equipment called an emitter to connect to it. The 3D Ready tv already has an emitter. You will also need a 3D bluray player or Playstation 3, 3D glasses, and hdmi version 1.4 cables. You will need 3D glasses and 3D bluray Dvds. If you want to watch something besides bluray dvds you would have to subscribe to direct tv as they are now offering some 3D broadcasting.

Do you also have a computer monitor attached to the computer when attempting to use the HDMI?

I have the LG lht854 home theater system and a LG42LG 40' LCD television which we purchased about 30 day’s ago. 20 minutes through watching a movie the picture cuts out on the screen for a couple seconds but not the sound /and then comes back it does this throughout the movie. We have tried different DVD’s but get the same results. This problem just started 10 days ago. What can we do?
