why are some hdmi cables more expensive?

HDMI is a digital signal standard. It replaces analog standards. Analog cable quality determines the output quality, but digital cables do not. So manufacturers are trying to fool consumers into thinking these expensive HDMI cables will improve the quality of the signal the same way the analog counterparts did.

Not all HDMI cables are the same. It's true that HDMI is a digital signal, and that as long as the signal is passed cleanly, you won't be able to tell the difference between two different cables.

The first and probably most important is that VGA uses an analog signal and HDMI uses a digital one. Due to that, running a VGA signal directly into a HDMI connector on a monitor could actually damage it, because the analog signals is at a higher voltage level.

The good news is that cheap HDMI cables are perfectly fine and you don't need an expensive HDMI cable for most TVs, including new ones with 4K resolution, high dynamic range (HDR) and Dolby Vision. ... Fortunately, you can get the maximum performance possible in the best HDMI cable out there for less than $10.

Three of the most commonly talked about cables through the decades are RCA cables, optical cables, and coaxial cables. ... Meanwhile, RCA cables are associated with analog signals. This is why optical cables offer superior sound quality and HDMI offers superior video and sound quality to RCA.

But you may need to replace them eventually The one caveat to all this is that while HDMI cables don't simply go bad over time– they may need to be replaced one day. There are physical damage reasons that that might happen, such as extreme force shearing the cable in two, or damaging the internal wiring.

Consumers often have no idea what the manufacturing cost is. This means manufacturers can easily price items high, whatever the market tolerates. Also, TVs are purchased in higher quantities than monitors, so it's easier to sell TVs cheaper for a profit than monitors.

The screen is incredibly expensive (or screens in the case of some of Sony's VR competitors), and it's a huge part of why these headsets cost so much money. Simply put: there are only so many companies making small, super high-resolution screens — the kind of screens required to power high-end VR headsets.

In terms of image quality, there is virtually no difference between HDMI and DP. The newer the version, the higher the maximum bandwidth and the supported resolution. It is in fact much more important to check the version than the standard (HDMI or DP) itself.

Cables can go bad, but it is a highly unlikely result. If you can get your hands on even an old CRT monitor to try it out on, that would even be great before just buying a new monitor.

Yup. VGA and DVI cables have gone bad on systems in my environment many a time. Luckily we have so many that I have to throw them away every once in a while due to the large surplus.

Most HDMI cables are passive, and can pass their signals in either direction. ... However, if you need to use a really long cable run (likely 30 feet or more), an Active HDMI cable may make the difference between a data-intensive signal making it or not, as HDMI cables generally become less reliable the longer they are.

Over short distances, say under 6 feet (2m), just about any recent "High Speed" HDMI cable should work fine. "High Speed" is the rating used by HDMI companies to indicate cables that have the bandwidth to handle 1080p and greater video resolutions. You can think of bandwidth like a pipe.

While HDMI and VGA are the two most common cable types, sometimes your laptop or TV will need a different cable, such as a DisplayPort (which carries both video and audio) or Composite Video (another Video-only cable that requires a second video for the sound).

When it comes down to 4K TV, you do not need to pick up special HDMI cables. The HDMI cable standard can impact color and resolution, but newer versions are not required for 4K TV.
