Question regarding 4K TV picture

I would think that even if it's not in the super 4K HD or whatever, it would still just be a "normal" HD. But like I said it's pretty standard-HD looking. Is there some type of setting I need to adjust? The same cable box and same HDMI cable that was going into my 6 year old Vizio one week ago looked perfectly fine and HD so it's gotta be something to do with this TV.

I mean it's not like it was $100. It was still in the high 3 digits and Vizio is a good name brand.

Any advice on the topic at hand?

Dig around for settings dealing with upscaling, refresh, motion blur, etc. Basically anything that looks like it might require the TV to process the image, toggle on/off and check the difference.

Try some 1080 content from a different source. For example, if the video from your cable box is blurry, open the youtube app and see how it looks with 1080 content.

It's very possible that, assuming this TV is larger than your old one, it's just magnifying how bad cable TV has been all along.

Go to Netflix.
Watch one of their Animal Planet-type shows that specifically says “4K.”

I guess that's my biggest question here...is there any way to get "regular" cable tv programming to play in HD on a 4K tv.

So the issue is that HD is 1080 pixels vertically, and 4K is 2160 pixels. That means something must be done to the signal in order to make that content "fit" on your screen. The simplest is to just take each pixel of the 1080 content and represent it using 4 pixels (2x2) on the 4K display. When done this way, the content should look about the same as it would on a 1080 display, minus the fact that if you look close enough you can tell that each pixel is actually 4 pixels. Another thing it could do is "upscale" the content, which is where the TV basically tries to fill in the gaps with what it thinks the extra pixels should look like. Done well, the content can look better. Done less well, the content can look worse. You might be experiencing a case of the latter, so maybe try finding the settings to turn that off. I really have no idea what Vizio might call the feature.

100%.

Your cable box and tv both have preferences to “play in highest quality resolution.” It’s just a matter of playing around with it to figure it out.

Just saying, Sony has the best upscale processor of them all. Sony is known for showing your original source in 4K the best. It is what sets it apart. The new XR processor is a game-changer.

That said, I still use Cox Cable on my Sony 77" A80J OLED TV and sometimes you have to check to see whether the program is actually coming in 4K or 1080p -- it is that good.

Vizio is a good American brand but you have to purchase their higher-end units to get their best quality. It does not have a deep lineup like Sony and Samsung have. If you paid in the $900 range for a 70" Vizio, you did not get a good deal quality wise.

Like a previous poster said, when you shop for a big TV on a low budget, you simply get what you pay for.

So, try better sources than Cox for 4K resolution. I always recommend Apple 4K TV boxes or the NVIDA Shield box. They stand out above all the Roku, FireSticks, etc. But, once again, you get what you pay for.

If you get an Apple 4K TV box ($185), it will detect your Vizio 70" 4K capabilities and send all of its content to you in Dolby Vision 4K (or an up-scaled version of it). Hard to beat for quality.

If you can still return the Vizio to Sam's, I would look at the Sony 65" X90J LCD TV which is supposed to drop to $999 next week. It also offers a 75" X90J that will drop to the $1500 range (maybe less) next week.

If you go with Samsung, do not buy less than their 80-series models. Their bargain 60- and 70-series models are proving to be problematic.

Now, if you are determined to stay under $1K, then take a closer look at the higher-end TLC and Hisense models. There you get quality but not longevity.

Theere is a lot of angst in buying quality TVs these days. You can scrimp on bedroom TVs, but don't try to save $100-$200 on your main den/living room unit.
