Top positive review
Finally, a decent review
Reviewed in the United States on March 23, 2022
To begin with, this review is for the Vizio D24f-J09. Amazon reviews can be very helpful...to a point. Unfortunately, they often include models other than the one you're viewing, so you have to be careful when relying on them. In this instance, reviews go as far back as 2018, which means they are for TV's other than this one.
I tried two other 24" TV's (LG and Insignia) and the pictures were very mediocre (although some reviewers thought they were fine). I had a Samsung 24" before with a beautiful picture, so I had something to compare them to. The picture on this TV is not as good, but it is pretty good, once adjusted properly (I'll speak to that in a moment). It is the most recent 24" TV from Vizio (as of March 2022). There is one other 24" model in their recent lineup, the D24f4-j01 which has a bezel-less design.
Of interest to almost everyone getting a 24" TV is the sound. Out of the box, the sound is OK, but not as loud as many would prefer. However, there is a way to correct this, which I'll get to shortly.
As to reliability, I've had this since November 2021, so it's too soon to tell. So far, so good, although Vizio has a bad track record in that regard.
It comes with lots of apps built in, probably all that most people would want. I don't see a way to add more. I can't tell you how well they work on the TV itself, as I use Amazon's Fire TV stick. With that, you can add tons of apps. That works very well.
There are two HDMI inputs on the back. It should be noted that this is not the traditional ultra-thin TV. It is 2 1/4" thick, which allow for better (not great) speakers.
OK, the settings you will need to get the best picture. This is the results of weeks of fine-tuning that seemed the best to me. You may need to make minor adjustments for your eye, but I suggest you try these for a few days before making any changes to allow yourself to get used to them.
Go to settings (the black and white "sun" button below the Pluto button on the upper left)/picture. These settings are in the order that they appear.
Color Temperature NORMAL
Now, for the sound. Go to Setting/Audio.
Volume Leveling ON (This will noticeably increase the volume)
Dialog enhancer HIGH
There you go. This seems to be one of the very best choices available for the ever shrinking 24" TV offering.
