LG 55EF9500 55-Inch 4K Ultra HD OLED TV.

Q: Does the LG Electronics 55EF9500 Flat 55-Inch 4K Ultra HD Smart OLED TV (2015 Model) have an Ethernet port to use instead of wifi?
A: Yes, it has an Ethernet port.

Q: Can this TV be mounted to the wall using a standard wall mount or do I have to buy one specific to the model?
A: If you can handle making an adapter plate, yes. Plate steel would be the best choice, however 3/8" Plywood would work as well. Of course do so at your own risk. The OTW150 is the LG mount that is recommended.

Q: What's the response time and refresh rate of this TV?
A: LG's 4K OLED native refresh is 120Hz. I do not know the input lag time.

Q: Can someone who owns this set tell me if watching 1080p or lower non-4k content on this set worse than watching it on a good 1080p HD set?
A: Non-4K material that is in 720p, 1080i, or 1080P will look better on this set versus most 1080HDtv's due to the up-conversion process which gives you 2000 lines.

Q: Does this TV support HDR?
A: The new flat model is also the first OLED TV we've seen from LG that's capable of playing high dynamic range (HDR) content.

Q: Can you mount this on any standard VESA mount?
A: Negative. You'll need to purchase the LG mount.

Q: What's the refresh rate of this TV? Does it reach 240hz, 120hz, and 50hz natively?
A: THE LG OLED TVs do not have a refresh rate. Refresh rate pertains to LED TVs.

Q: How is this TV with video games (Xbox One)?
A: I have the 65" version and I've played single player games like Mad Max which requires precise timings for counter attacks and In Game mode it seems very responsive. Haven't tried any multiplayer yet.

Q: Is this a flat panel or curved?
A: LG's new EF9500 is the latest 4K OLED TV and it's flat. The EF9500 series comes in 55" and 65" screen sizes. If you want the gently curved version it's the EG9600 series.

Q: Has anyone successfully mounted this TV to a wall using an articulated wall mount and having metal studs inside your walls?
A: It can be done but be very careful in that application, be careful, try at your own risk. If it was wood studs you would have 0 issue. I think you would need to remove the drywall between the two studs throw a 2x12 in the wall, then patch the drywall. You could try using toggle bolts in the two studs but that's risky. This is the mount I would use but you will have to fabricate a plate so all 4 holes line up on the mount to the TV, as out of the box only 2 holes will line up. Once you get it you will see what I am talking about. Search for this mount here on Amazon >>>> Peerless Full-Motion Plus Wall Mount for 40-Inch - 75-Inch.

Q: How good is this TV when watching non-4k content?
