The main difference between an HD, FHD, UHD, or 4K television is that the 4K television will have a sharper picture than an HD television.
HD
HD or High Definition has a width of 1280 x 720 pixels (<1 megapixel). HD is also referred to as HD ready and 720p.
> HD TV
Full HD
Full HD or FHD is the resolution currently found on most televisions, Blu-ray players, and video content. The image is 1920 pixels wide and 1080 pixels high (2.07 megapixels). Full HD is also referred to as 1080i and 1080p.
> FHD
Ultra HD
Ultra HD also known as UHD is increasingly popular among televisions, media players and video content. The image resolution is 3840 x 2160 (8.3 megapixels). TVs with Ultra HD resolution display 4 times more pixels than Full HD images.
> UHD
4K
4K has a resolution of 4,096 × 2,160 (8.8 megapixels), a little higher than UHD.
Better resolution at the same image size
A better resolution TV (eg UHD vs FHD) displays a greater number of pixels and allows more details to be displayed on an image of the same size. The materials, the textures, the skin texture of the actors, the backgrounds: everything is richer and more realistic.
At the same diagonal, the higher the definition, the higher the image quality and therefore the more precise and detailed the image. A 4K definition television has 4x more pixels than an HDTV to display the same scene on the same surface. At the same time, the resolution is multiplied by a factor of 2.
A larger image at equal distance
It is the second advantage of switching to a higher definition image: if we increase the number of pixels in the image, we can therefore enjoy a larger image while maintaining the same distance between the screen and the viewers, without however distinguishing the pixels which compose it.
For example, you can switch without fear from a 32-inch (80 cm) 1080p HD television placed 2.5 m from viewers to a 65-inch (164 cm) UHD television, without having to move the sofa back. The image will be much larger and the immersion much better, but the pixels that make up the image will remain invisible to viewers at this distance.
Note: In order to take full advantage of a 4K image, the entire signal transition chain must be capable of encoding, transmitting, receiving, decoding and displaying 4K. In other words, the camera used to record the film must be 4K, the signal transmission is in 4K, the reception (TNT, cable or SAT) can receive 4K, the cables (between box and TV for example) or 4K, the receiver decoding is 4K, the receiver panel is 4K.

Answer
Add commands to the Quick Access Toolbar (QAT) so they are easy to use. There are instructions and examples below.
Also, be sure to export your QAT customizations, so you can use them on other computers, or when installing a new version of Excel.
Some Excel commands are on the Ribbon, but in submenus, where it takes a few clicks to get to them. For example, to it normally takes 4 steps to change the report layout of a pivot table:
If you usually change the pivot table to Tabular Layout, add that command to the QAT (follow the steps below). Then, it only takes 2 steps to change the report layout of a pivot table.
To add the Tabular Layout command to the QAT:
The "Show in Tabular Form" command is added to the right end of the QAT.
In Excel 2013, each file opens in its own window, and has its own Close button. To make it easier to close multiple windows quickly, you can add the Close All and Exit commands to the QAT.
Watch this video to see the steps.
If you use an Excel command frequently, or if an Excel command isn't available on the Excel Ribbon, you can add its icon to the Quick Access Toolbar (QAT). This short video shows the steps, and the written instructions are below the video.
For example, here are the steps to add a macro to the QAT. The macro is named ToggleR1C1 and is stored in the Personal Macro Workbook.
To add a macro to the QAT, follow these steps:
The macro icon now appears on the QAT, and you can click it to run the macro.
You can also add commands to the QAT for a specific workbook only. For example, if you frequently add comments in a specific workbook, add the Insert a Comment button for that workbook only.
Watch this video to see the steps, and the written instructions are below the video.
To add a QAT command for a specific workbook, follow these steps:
The command appears on the QAT when the Project file is active, and disappears when a different workbook is active.
If you no longer need an Excel command on the QAT, you can remove it. For example, here are the steps to remove a macro from the QAT.
The icon is removed immediately, without any confirmation message.
After you add or remove commands on the QAT or the Ribbon, you should export the current settings. Then, if you want to set up a new computer, or if you have to re-install Excel, you can import those saved settings.
To export your Ribbon and QAT settings, follow these steps:
To import your saved Ribbon and QAT customizations, follow these steps:
To quickly use the commands on the QAT, use the keyboard shortcut, Alt + [QAT button number]
For example, if Clear Filters is the first command at the left of the QAT, press Alt + 1
That will clear the filters in the selected pivot table or Excel table.
You can also customize the Excel Ribbon, by moving or removing the groups on a default Ribbon tab. In this video, see how to move groups on the Data tab, so the tools that are used most often are in the middle of the tab, and easier to reach.
