Q: We have a 36" wide opening for a tv, will this fit? Dimensions say it will but can someone measure exactly and tell me if they are just shy of 36" like it states? If so, it will fit. Thanks!

A: Yes. I just setup the VIZIO D40U-D1 TV and it measured 35-7/8" wide by 23-1/4" tall, including the stand/legs. It is 21-3/8" tall without the stand.

Q: Why does this TV have an analog tuner? I thought there was no such thing any longer as analog, that everything switched over to digital some time ago.

A: The tuner on the D40u-D1 is both an analog and digital tuner. There are some cable providers who still use analog signals. Thanks!-Jesse

Q: Does this TV get Google play

A: No, this does not get Google play.

Q: Does it stream Amazon Prime? I didn't see it listed. Thanks!

A: It has Amazon instant video and Amazon Prime.

Q: I just got the vizio model D40U-D1. is the there any way to see the OTA signal strength of a channel using my outdoor antenna?

A: "MOST" VIZIOS - GO TO MENU> SYSTEM INFORMATION AND THEN SCROLL DOWN TO CHANNEL INFORMATION-SIGNAL QUALITY

Q: Can I plan video from a USB? I'm told the SmartCast ones can't so I want to make sure this one can.

A: This model supports video, audio and photo file types. Please feel free to contact us at chat.vizio.com or 1-877-878-4946 and we would be happy to help you. -Randal

Q: Does this TV Upscale form HD to UHD?

A: Vizio is using the word "upscale" very loosely. The source resolution is the resolution you get. It tries to make it look better but there is a HUGE difference between a native 1080P source and a native 2160P source. You cannot make the original signal much better than it actually is. Just think about the difference between a DVD and a Blu-Ray in an upscaling player. Anyone can tell the difference. In fact I to me it is quite the opposite. Bad resolution sources look worse on better TV's.
