What People Are Saying

Rated 3 out of 5 by from Good Sound, but Menu is lacking The remote has buttons that arn't even used. You have to drill 3 to 4 layers down just to get to where you can change the output from the built in speakers to other out put options. Something like that should be on the remote.

Rated 5 out of 5 by from A totally immersive presence in the room The equipment is an engineering marvel, but the picture is unbelievable. Deep rich blacks and brilliant vibrant colors captivate you. It dominates the room, you can't take your eyes off of it.

what is the difference between 98UB9800  and 98UB9810 models please? Eddie

Asked by: Edido
Both the LG 98" Class (97.5" Diagonal) UHD 4K Smart 3D LED TV w/ webOS™, Models # 98UB9800 and the # 98UB9810 are discontinued TVs. The difference between the two was that the 98UB8100 was a true VESA compliant TV with an A x B VESA Wall Mount Pattern of 800 x 400 so you could use an VESA Compliant Wall Mount that supported that Wall Mount Pattern. The 98UB9800 only had screw point for eye-bolts so it could be hung with cables...^IFV

 If only port one is HDCP 2.2 compatible will I be getting full video quality and benefit of the 4K that is available on ports two and three?   If not we've  obviously got a major problem. Customer service says all 4 are?  Who's correct?

Asked by: VMK TX
We regret your dissatisfaction with the design of this television. According to the information on page 23 of your owner’s manual, the HDCP 2.2 protocol is only available on the HDMI1 port.

 Are all of the porch HDCP 2.2 compatible.  I've tried two and three and I'm getting a message on both?

Asked by: VMK TX
I apologize, but no; according to the information listed on page 23 of the owner’s manual, it appears that only HDMI1 will be compliant with the HDCP 2.2 protocol.

 I am connecting a DirecTV Genie 4K to my TV. Does it matter which one of the HDMI inputs it goes to? (Arc etc.).   I'm currently getting a message that says my TV does not support 4K ?

Asked by: VMK TX
 I've tried those ports and have also seen a message showing that I do not have HDCP 2.2?   Is this TV compatible with that standard ?

How do you restart the TV after update

Asked by: Jcviper
We appreciate your interest in this television. It may be suggested to allow the TV to restart itself, once an update is complete. After that, you may choose to turn the TV off again, using the Joystick Control button on the bottom of the set.
