FHD vs UHD: what are the differences?
When consumers purchase a TV or domicile theater, consumers are bombarded amongst confusing terminology. Two of these terms are FHD in addition to UHD. Both are important, but what make they mean?
This information applies to producer televisions including, for example, LG, Panasonic, Samsung, Sony, TCL, and Vizio. Additional devices compatible amongst FHD in addition to UHD are made past times these in addition to other manufacturers.
What is FHD
FHD stands for Full HD or Full High Definition in addition to refers to a 1080p video resolution. This agency that a 1080p TV is an FHD TV.
- The 1,920 pixel columns are arranged on the enshroud from left to right, acre the 1,080 pixels are arranged inwards rows or lines that decease from peak to bottom of the screen.
- Each row of pixels is displayed progressively on the enshroud (each work next the other inwards numerical sequence). This is what "p" agency inwards 1080p.
- The total pose out of pixels on a enshroud is determined past times multiplying the pose out of pixels upwards (1920) in addition to downwardly (1080), which is equivalent to 2,073,600 (about 2 megapixels).
- FHD TVs tin last made using Plasma, LCD (including LED / LCD in addition to QLED ), OLED in addition to DLP technologies. DLP in addition to plasma TVs create got been discontinued but are suitable for those who ain or expose a used one.
The term FHD is used to distinguish 1080p from other high definition (HD) resolutions, such equally 720p in addition to 1080i.
What is UHD
UHD stands for Ultra HD or Ultra High Definition, which is also commonly referred to equally 4K.
- UHD is non exactly 4K, but for consumer TVs in addition to related devices, it is considered quite close. As a result, 4K, Ultra HD, Ultra High Definition in addition to UHD are oft used interchangeably.
- UHD is 3,840 x 2160 pixels. There are 3,840 columns (approximately 4K) arranged from left to correct in addition to 2,160 pixels arranged inwards rows from peak to bottom of the screen, which is displayed progressively (2160p). The total pose out of pixels is 8,294,400 (about 8 megapixels).
- UHD has 4 times the pixels (or twice equally many columns in addition to rows) equally FHD (or 1080p). Four FHD images tin adapt to the infinite of a UHD image. UHD resolution is twice FHD resolution.
4K is to a greater extent than exactly 4096 x 2160 pixels, which is slightly wider inwards horizontal but is the same inwards vertical. The total pose out of pixels is 8,847,360. This measure is used inwards commercial cinema.
- Although UHD is resolution based, TV manufacturers create got incorporated additional features into many TVs in addition to UHD devices, such equally HDR in addition to a broad make of colors, non commonly included amongst FHD TVs. These improvements create got a greater visual send upon on the viewer than simply resolution. Some high-end UHD TVs that contain these additional features reckon the Ultra hard disk Premium standards.
What yous postulate to reckon FHD
To reckon the native 1080p resolution on an FHD TV, rootage in addition to content devices are required that tin supply 1080p resolution (FHD) signals such as:
- Blu-ray Disc.
- Select streaming content from services similar Netflix, Amazon, Hulu, Vudu, etc., supplied straight on a smart TV or via streaming media plug-ins.
- Select the boxes via cable/satellite in addition to the associated content.
- Select digital cameras in addition to camcorders that tape images in addition to videos amongst 1080p resolution.
- Most game consoles.
Broadcast TV is non available inwards 1080p (FHD). Most stations broadcast inwards hard disk at 720p or 1080i.
Technically, 1080i in addition to 1080p create got the same resolution, but 1080i is displayed using rows of pixels displayed alternately rather than progressively. This agency that solely one-half of the resolution is transferred from i rootage to a TV simultaneously.
NON-HD RESOLUTION SOURCES (SD) INCLUDE:
- A DVD piece of work musician or a DVD recorder.
- VHS video recorders.
- Standard resolution analog in addition to digital cameras.
A Full hard disk TV tin display low-resolution signals through upscaling or video processing. Upscaling is non the same equally truthful FHD but tin supply a much meliorate picture than an unmagnified image. The lineament of the upscaling varies according to the build in addition to TV model. Furthermore, if 1080p upscaling is performed past times a rootage device, the FHD TV volition expose it equally a Full hard disk signal in addition to volition non perform farther upscaling.
What yous postulate to reckon UHD
With a UHD TV (4K or Ultra HD), non everything yous reckon on the enshroud is necessarily inwards UHD. UHD TVs are compatible amongst the same sources equally a FHD TV, but to accept total wages of UHD resolution, the best sources are:
- Blu-ray Disc UHD : provides movies amongst native UHD resolution via a disc format. This requires the purchase of a novel piece of work musician in addition to discs, but readers tin yet play DVDs in addition to Blu-ray discs.
- UHD via cable: Comcast provides UHD content directly, but the pick is real limited. There is a lack of UHD content on other cable services, amongst the exception of streaming rather than straight via cable.
- UHD via satellite: available from Direct TV in addition to Dish Network.
- Streaming UHD : Netflix, Vudu, in addition to Amazon Prime Video are some of the streaming services that offering 4K (UHD) content. These services are available on Roku, Amazon (Fire TV), Apple TV, Google Chromecast in addition to selected Smart TV UHD streamers. An Internet speed of fifteen to 25 Mbps is required for stable viewing.
While native UHD content is preferred, simply similar amongst FHD TVs, UHD TVs tin lift SD in addition to hard disk content at depression resolution to meliorate check UHD TV display resolution.
As of 2019, at that topographic point are no publicly available UHD over-the-air TV broadcasts, although they are coming
Cables in addition to connections for FHD in addition to UHD
To teach video signals from a rootage to an FHD or UHD TV at that topographic point are wired in addition to wireless connexion options.
WIRED CONNECTIONS
HDMI : this is the measure wired connexion for FHD in addition to UHD rootage devices. Depending on the version or versions of HDMI a specific cable is compatible amongst determines the resolution in addition to other features provided inwards combination amongst the rootage device in addition to the TV. For UHD TVs utilisation cables labeled "high speed". HDMI is flora on all Blu-ray / Ultra hard disk Blu-ray players, most multimedia streamers, cable/satellite decoders, game consoles, in addition to PCs in addition to laptops.
Source devices amongst Display Port, DVI, VGA connections tin last connected to the HDMI inputs of an FHD or UHD TV via adapters or adapter cables. It is real rare to expose a TV amongst a DisplayPort connection, but yous tin expose DVI in addition to / or VGA connections on some older FHD in addition to UHD TVs.
Composite video: Analog rootage devices, such equally a VCR, DVD recorder, analog video photographic tv camera or DVD piece of work musician without HDMI output, tin last connected to most FHD in addition to UHD TVs using a composite video connection. The signals volition last a measure resolution (480i). Composite video connections cannot transmit analog or digital hard disk video signals.
Component Video: this connexion uses iii RCA connectors amongst red, greenish in addition to bluish ends. Component video connections create got been developed to transfer resolutions upwards to 1080p, but since they are analog inwards nature in addition to plain of written report to piracy, they were express to measure resolution afterwards 2011. On most FHD in addition to UHD TVs, cistron video inputs tin last combined amongst composite video inputs. This agency that it is non possible to simultaneously connect a composite video in addition to cistron rootage to most FHD in addition to UHD TVs.
USB: many FHD in addition to UHD TVs supply at to the lowest degree i USB port. Some TVs may include this solely for service use, but most allow the reproduction of yet images, videos, in addition to well files via plug-in flash units.
Some intelligent FHD in addition to UHD televisions allow the connexion of a USB keyboard and/or mouse equally an alternative way to navigate the TV menu, such equally entering password access and/or browsing the Web if the TV includes an embedded Web browser.
Ethernet: on FHD or UHD smart TV, some other connexion usually provided is Ethernet (aka LAN). This allows the integration of a smart FHD or UHD TV into a domicile network via a router, providing Internet access. From at that topographic point yous tin install firmware updates in addition to play audio, video in addition to yet picture content stored on a PC or current movies in addition to TV programs from online services.
WIRELESS CONNECTIONS
Wi-Fi: most Smart FHD in addition to UHD TVs offering integrated Wi-Fi. This performs the same part equally an Ethernet cable, but since it is wireless it is to a greater extent than convenient if the TV is away from the router. However, Wi-Fi is non equally stable equally a physical connection, which tin drive inconsistent results when streaming video content, particularly 4K video content.
Screen Mirroring/Casting: some other way to persuasion content wirelessly on many smart FHD or UHD TVs is through Screen Mirroring or Casting from a compatible smartphone, tablet or PC. Depending on the mirroring/casting device, yous may create got access to FHD or UHD resolution inwards combination amongst compatible content.
Viewing distance TV FHD in addition to UHD
Getting the most out of an FHD or UHD TV depends non solely on the content sources, but also on the size of the enshroud in addition to the distance yous sit.
If yous create got a 55 or 65 inches UHD TV, yous tin sit down equally closed equally yous tin amongst an FHD TV of the same enshroud size in addition to yet savor a comfortable viewing experience. The argue is that the pixels are much smaller on a UHD TV than on an equivalent FHD TV. As a result, the distance at which UHD TV pixels teach visible is much closer.
The next tabular array outlines a make of suggested viewing distances for the most mutual dimensions of the diagonal enshroud TV (D).
| OPTIMAL VIEWING DISTANCES FOR FHD AND UHD TVs | ||
| Diagonal enshroud size (D-inch) | Screen width (inches) | Viewing distance (feet) |
| 40 | 34.9 | 4.3 - 8.3 |
| 43 | 37.5 | 4.6 - 9.0 |
| 50 | 43.6 | 5.4 - 10.4 |
| 55 | 47.9 | 5.9 - 11.5 |
| 65 | 56.7 | 7.2 - 13.5 |
| 75 | 65.2 | 8.10 - 15.6 |
| 85 | 73.9 | 9.25 - 17.7 |
For FHD TVs, firstly amongst the highest pose out in addition to conduct the sitting topographic point closer. For UHD TVs, firstly amongst the lowest pose out in addition to displace the seats backward, if necessary, for a to a greater extent than comfortable distance. At the betoken where yous laid out to reckon the pixels, or maybe the hardness of the edge, yous are also close.
Conclusion
Depending on your needs in addition to desires, FHD (1080p) tin offering a proficient visual experience, but UHD (4K) farther enhances the experience, particularly on larger screens. However, hold the next inwards mind:
- Now it is rare to expose an FHD TV amongst enshroud sizes greater than 49 inches or a UHD TV amongst enshroud sizes less than xl inches. Make certain the size yous select is correct for your viewing environment.
- Make certain yous create got access to the most suitable content for viewing FHD or UHD (over the air, cable/satellite, streaming, Blu-ray, etc.).
- Make certain that FHD or UHD TV provides the necessary connections for your other devices (antenna, disc player, multimedia streamer, game console, etc.).
- Control FHD or UHD TVs in addition to other devices for the features yous wishing (refresh rate/motion processing, smart features, HDR, broad color gamut, lite output, repose of use).
- FHD in addition to UHD televisions create got a broad make of prices depending on the brand, model, enshroud size in addition to features, from the hundreds depression to the high thousands.
