I have a 4K Samsung.

All HDR seems to do is turn the backlight to eyeball searing and max out the contrast.

The BBC UHD feeds look stunning in 4k, but I think that is more a case of the 1080 feeds are such low quality and the UHD content is carefully selected, as I can't see a difference that I'm not imagining on 4K blu-ray vs 1080.

Although to be fair, most "4k" blu-ray is upscaled, which is what the TV does anyway!

I think 4k is a sales gimmick if you watch the TV at sofa distances.

That would depend on where your sofa is....If you are in the average lounge layout you may be right, but why pay for a really good TV then sit in the wrong position so that you can't benefit?

I'm never surprised anymore. People seem to mount their TV too high up and have their furniture pushed against a wall because it's too big for the room. 

Agreed, I have a pet hate of TV's mounted over fireplaces as well as any TV that's too big for the room that it's being viewed in.

TV that's too big for the room that it's being viewed in.

Even worse is a tiny 32" TV in a large living room

Having a 50 inch + in living room fine 

if I were to have anything bigger than 43 inch tv it look stupid in my room 

my Current Jvc Full Hd tv I is around 4 years old but It feels like more new ps5 games I buy my tv struggling with providing proper colour and at times if am making quick movements you see like a outline blur plus currently playing new final fantasy and the sky looks static or dusty , the mountains in distance lack detail - it like looking a pitchy painting 

when the characters speak it Mouth slightly feels dealy with the words

It depends a lot on the TV technology, LCD and LED all have issues with fast moving images, OLED is the best by an absolute mile. Do you have the TV in game mode/all image processing turned off on the HDMI feed? It may have image processing turned on by default that looks fine for normal content but makes games look muddy and potentially washed out, the fact that you are seeing a delay with speaking would indicate that some of that processing is enabled as without it the feed should be instantaneous. FFXVI can be a great looking game, but it did have issues with over zealous motion blur, thankfully in the latest update they added a setting that lets you amend it, I find it much better on 1 or 2 than on the original setting/5. I would also double check the settings on the PS5, you want the PS5 to downsample the image to 1080p with the correct colour space, rather than letting the TV do it.

Depends on the size of your screen and the distance from it. With a 110" projector screen you can certainly tell the difference between 4k and 1080.

There also information if you set game to 1080p on 4k tv you can get 120hz  but how does this impact graphics? 

Some tv have features that allow to enable 120 fresh rate for gaming or have blur reduction or motion clarity 

do they actually work??? 

Any advice please. I don’t know we’re to start or what to get 

Both games consoles and TVs have finite processing power/bandwidth. With the top end you can get 120hz on 4k (or 8k for that matter) but many will offer 120hz on 1080 but 60hz on 4k as they cannot deal with the amount of data. Resolution impacts how good the graphics look, refresh rate impacts the smoothness of motion.

Ultimately a screen is limited by the quality of the source. No matter the claims of snake oil a screen cannot materially make up extra detail or smoother motion than what the source gives them. If a source gives 30 FPS and the TV refreshes at 120Hz then either it shows the same frame 4 times or it averages the current and the next frame and creates a smearing effect.

How far are you sitting away from your screen? What resolution is of benefit depends on a combination of screen size and distance. I use a 5k monitor for computer/gaming but obviously sit 0.5cm from it so benefit from it. If I sat 4m away from it, as I do our TV, there'd be no benefit over a 1080 screen. On the flip side our projector is 110" and would need to be a very long way away not to get the benefit... indeed it'd benefit an 8k projector (if there was any material in the UK to use on it) but I dont have enough kidneys to sell to afford such a projector.

I sit 8 to 9 feet away from tv - 43 inch best for were am putting tv 

I don’t get why how far you sit matters 


If tv quality shows finer details, better colour etc - even a fairly good range you see it being better than another 


From what I read so far online and here has give me more insight 

If you take it to an extreme for the purposes of illustration... if you sat 100m from your 43" TV you'd probably tell if its on or off, may have a guess at the sort of program its displaying but you aren't going to be able to see each of Gandalf's eyelashes at that distance. 

Whatever resolution your TV is it has the same number of pixels if it's 14" or 140", just the size of each pixel is different. Even with 20/20 vision you can only see things of a certain size at a certain distance and so a small screen far away you cannot tell the difference between 1080 and 4k and so there is little point introducing the overhead of 4k if you cannot benefit from it. The inverse happens with very large screens, sit too close and 720 content will look terrible. 

finer detail isnt an argument, that is a function of resolution. Better colour and better motion handling possibly are but the later is a double edge sword, moving to 4k requires much better motion handing than 1080 did given all the additional data to be dealt with.
