HDMI is not one thing
All HDMI plugs look identical, but the cables differ dramatically in bandwidth. An old cable carries Full HD comfortably; the same cable on a 4K display at a high refresh rate will give lower resolution, flicker, or no picture at all.
And worse: the symptom looks like a device fault. People suspect the monitor or the graphics card, when a cable costing a few euro is to blame.
The rule: if you are aiming for 4K, a high refresh rate or HDR, choose a cable that states it explicitly in the specifications.
HDMI or DisplayPort?
HDMI — the universal standard. Televisions, consoles, receivers, projectors and almost every monitor have it. If you are connecting to a TV, it is the only route.
DisplayPort — the computer standard. Usually better support for high refresh rates and for multiple monitors from one port. If you have a graphics card and a gaming monitor, it is the preferable choice.
Older standards such as DVI and VGA still serve hall projectors, older monitors and industrial equipment that works fine and is not being replaced.
Length and audio
On digital video cables, long runs have a limit. Beyond a few metres a plain passive cable starts losing signal — dropouts or "sparkle" appear. For long distances you need an active cable or a converter.
On audio: optical cables carry a digital signal as light and are immune to electrical interference. Analogue 3.5 mm and RCA are more vulnerable to noise, especially over long runs beside mains cables.

Frequently asked questions
- Why do I not get 4K on my monitor?
- Very often the cable is to blame. You need HDMI or DisplayPort that explicitly states 4K support at the refresh rate you want.
- HDMI or DisplayPort?
- HDMI for televisions, consoles and projectors. DisplayPort for computers and gaming monitors, with better support for high refresh rates.
- How long an HDMI cable can I use?
- Beyond a few metres a plain cable loses signal. For long distances you need an active cable or a converter.
- I have an old VGA monitor. Can it connect?
- Yes, with the right cable or converter. Note that VGA is analogue and carries no audio.
- Do expensive HDMI cables give a better picture?
- No. A digital signal either passes correctly or it does not. What matters is that the cable supports the resolution and refresh rate you want.
Before suspecting the monitor or the graphics card, try another cable. It is the cheapest test and the most frequently successful one.
