Best 40" TV For Guest Bedroom

Was looking for a smart TV that would fit in an armoire in our guest bedroom. This Vizio was one of the only in a 40" that would fit. I liked that it was 1080p and also had Bluetooth to link up to my headphones. Was a great value at $150 bucks, and got it delivered the same day!

Well worth the money. Picture and sound are great. Linked to WiFi in no time. If you looking for an inexpensive, good quality tv this is a good choice

Great picture with no buffering

I purchased a 40” QLED TV from Best Buy 2 months ago and this one replaced it. The TCL TV buffered for too long when you turned it on and then when it quit buffering it would tune to the last channel and show I was watching 24 hours ago. I pulled this Vizio out of the box to ensure that it did not do the same thing, and to my delight it worked just like you would expect a TV to work

Vizio TV

Overall, the TV works well. The sound could be better, but fine for the price point. I would recommend purchasing the tv, it is solid.

The clarity of the screen is amazing. The color is so vibrant. What I don't like is the size if the remote. It's too small. I added the remote app to my phone. Problem solved.

Quality, sound, and slow

Quaily cheap Dislike the remote cannot just put channels in without scrolling until you find one you like. Will occasionally turn itself back on or doesn't shut off. Picture is good. Sound volume has to be turned up high unless you have a sound bar. Takes a while to open up so slow to warm up

Problematic sound

I use it as a computer monitor. You don't need to install the phone app for that, just exit the initial setup with the back arrow. My old Vizio remote works. The new remote has a ring on top that serves as an ok and navigation button - it's not marked OK so I thought it's just a decoration not a button. To get normal colors for a monitor, not "bubble gum", I set the sharpness to 0, color to 35, color temperature to normal, brightness to 26, black level and contrast to 50. Adjusting the sound was a bit more problematic. The bass is so enhanced that it gave me headache listening to it from 2 feet, so I set the bass to -5 and turned off all sound "enhancements" which distort the sound. Sometimes, when I wake up the TV, the sound output is reduced, so I have to turn it off and on again. It's not supposed to do that from the very beginning, so I worry it may not last 10 years as my old Vizio.

Poor TV quality

Purchased tv over 40 days or so and picture has gone out. No sound and just static picture. Hopefully will be able to return because I'm in the 90 day window.

the stands do not screw in tightly they're loose and the TV tips forward and back unless you have a mouth for it I've broke three of these TVs because they fall over because the stand are pieces of crap
