Each TV has a bunch of settings to regulate the image high quality. Whereas altering your TV’s picture mode can do a ton in getting it to look its greatest, there’s one function that deserves particular consideration. It is referred to as “Sharpness” and whereas that appears simple, it is really not doing what you’d assume. Consider it or not, turning this setting down can really enhance your TV’s picture.
I completely perceive desirous to get probably the most element out of your 4K TV, however the reality is, the sharpness management would not really enhance the TV’s sharpness. With most TVs, it really masks high quality element. Because of this when your sharpness is about too excessive, you might lose among the crisp element attainable on that new TV. In some circumstances, one of the best sharpness setting is definitely zero, whereas on most TVs the setting is greatest within the backside 20% or so.
It is comprehensible if you happen to’re confused. In any case, a picture that is too bright or garish is simple to know, however sharpness takes some explaining. Don’t be concerned. I am going to clarify all of it beneath.
If you wish to dive deeper into what settings are greatest on your particular TV, find out about the best picture mode and the results of changing these additional settings.
Sharpness means edge enhancement
On practically all TVs, the sharpness management provides one thing referred to as “edge enhancement.” That is precisely what it seems like. The perimeters within the picture are enhanced, primarily by including a skinny define or halo to them. This makes them extra seen.
Left: the unique picture. Proper: the edge-enhanced “sharper” model. The “halo impact” is what the sharpness management provides.
Check out the side-by-side photos above. The left picture is the au naturel model. The suitable has important quantities of edge enhancement added. Word the define across the buildings. Whereas the left picture would possibly seem, at first look, “mushy,” it really is not.
The image beneath is a close-up of the “sharpened” edge-enhanced model. As you will see, a type of white halo seems round distinct edges.
Discover the slight halo alongside the perimeters of the buildings. That is edge enhancement, and it could actually masks high quality element and make a TV’s picture look much less pure.
The issue is that the halo should not be there — and it is changing what ought to be. It could not appear to be an enormous deal on this picture, however with most content material that halo is protecting the precise element. Moreover, it usually brings out grainy noise in different components of the picture. See how a lot cleaner the left picture seems in comparison with the improved.
Edge enhancement positively provides the picture a sure look: It will probably present the look of extra element. Most TVs have their sharpness controls turned up within the default image modes, so we’re used to this faux-detail look. Dynamic, Vivid, or Sports activities modes usually have a lot of edge enhancement, however they don’t seem to be the one modes that do.
Whereas unenhanced photos can look mushy by comparability, particularly at first, they’re really extra detailed as a result of they present high quality textures in partitions, pores on faces and tiny hairs — all of which could be hidden by an excessive amount of edge enhancement.
What’s one of the best sharpness setting for my TV?
The simplest method to test is to modify your TV to the Film or Cinema image preset, and see the place the sharpness management is in that mode. No matter that quantity is, it is a good place to start out.

Need to fine-tune it? Whereas watching quite a lot of content material, particularly 4K if in case you have a 4K TV, flip the management down from that start line and see what occurs. Does the high quality element disappear? In that case, that is too low. Ideally, you can discover the spot that gives probably the most precise element and the least extra noise. Do not be stunned if that quantity is 0.
Some TVs actively soften the picture while you flip the sharpness management to zero (and even beneath 50 in some circumstances). This may be carried out to supply a method to lower the noise in lower-quality sources, however I would be shocked if it is ever used for that objective. Simply one thing to remember. If the picture out of the blue seems blurry, that is positively too low. There is a candy spot with any TV, it is only a matter of discovering it.
A setup Blu-ray disc, just like the Spears & Munsil UHD HDR Benchmark, has patterns that can make it simpler to seek out the precise sharpness degree on your particular TV.
It is attainable, although uncommon, that you’ve a TV with everlasting edge enhancement. Even turning the sharpness management to zero and going by each setting (and film preset) in your TV, you continue to may even see edge enhancement or different processing. This was extra widespread with older TV units, although. Today it is pretty uncommon.

What about different visible controls?
Many TVs and a few high-end projectors have processing options separate from the sharpness management. These are often deeper within the settings menus, or in separate “superior” sections. A few of these can improve the obvious element with out including undue quantities of edge enhancement. Others, in fact, do extra hurt than good.
The assorted steps in Samsung’s AI Upscaling course of.
A part of that is as a result of enhance in total processing energy accessible in mid- and high-end TVs. As an example, Samsung, LG, and Sony have discussed using AI for their upconversion, which is the way you get a decent-looking lower-resolution picture on a high-resolution tv.
There is no blanket recommendation right here. In case your TV has these decision/element enhancement options, check out every to see what they do. Sit shut, and see if it is including noise, edge enhancement or if it is making the picture seem sharper. Purists will doubtless wish to preserve these options off, particularly with high-quality content material like from a 4K Blu-ray, however with some content material it would assist.
When you’ve got a Blu-ray participant you may get a particular disc to assist arrange the image correctly. One of the complete is the Spears & Munsil UHD benchmark, a disc CNET makes use of in our TV lab. Word that it requires a 4K Blu-ray participant.
Why you generally cannot flip down the sharpness
Often, the sting enhancement is within the supply. This was widespread on early DVDs, the place edge enhancement was added to make them “pop.” If it is within the supply, there’s nothing you are able to do about it. It is simply one thing to remember if you happen to’re making an attempt out completely different settings, do not use only one supply or program.
There are additionally some sources, usually low-quality video like standard-def TV channels and even VHS tapes, that may profit from a TV’s element enhancement circuits. These sources are so mushy and low-resolution to start with, that when blown as much as the scale of at present’s massive televisions they could look higher enhanced.
TV producers love edge enhancement, largely as a result of it makes their TVs appear tremendous detailed when seen in a retailer. Some cheap TVs may need nondefeatable edge enhancement. So irrespective of how low the sharpness management is, there’s some edge enhancement. There’s not a lot you are able to do about it in that case, sadly.
Sharpness wanting bizarre? Give it a couple of days
When you go to your TV proper now and switch the sharpness management all the best way down the image is totally going to look mushy. Very similar to with high color temperatures, anybody who is not used to creating high quality changes to their TV controls has gotten used to a sure “look” to their TV’s image. So at first, even the proper sharpness setting might sound mushy, particularly in case your TV has been within the Vivid or Dynamic image mode.
Attempt the brand new, decrease sharpness setting for a couple of days. When you then do not just like the look of the unenhanced picture, that is high quality. Flip it again up. However I guess while you do, the “unique” setting will look bizarre and the “decrease” sharpness mode will look much better.
