ZDNET's cardinal takeaways
- DisplayPort cables are designed to transportation powerfulness to monitors.
- With cheaper options, misaligned pins whitethorn origin powerfulness failures.
- You tin debar this by opting for a VESA-certified DisplayPort cable.
The DisplayPort "Death Pin" issue, oregon much formally known arsenic the Pin 20 Problem, is simply a well-known manufacturing defect successful which the past interaction pin connected a DisplayPort cablegram is wired incorrectly.
This creates a nonstop electrical transportation betwixt your show and graphics card, allowing powerfulness to travel freely betwixt them and causing terrible damage. And successful a clip wherever GPU prices regularly apical $1,500, it's champion to instrumentality each precaution to support your Nvidia oregon AMD paper from becoming a precise costly paperweight.

Fortunately, the champion solution is arsenic casual arsenic selecting the close DisplayPort cable. But determination are a fewer things we request to recognize archetypal successful bid to spot however the Death Pin tin wreak havoc connected your gaming PC oregon workstation.
What is Pin 20?
If you've ever looked astatine the extremity of a DisplayPort connection, you whitethorn person noticed a bid of small, gold-colored connections lining the inside. Each is nestled successful a tiny notch made to acceptable the corresponding interaction successful your monitor's DisplayPort input, and you'll beryllium capable to number 20 pins (as opposed to HDMI's 19-pin configuration).
Each pin is designed for a circumstantial function, mostly electrical grounding and audio/video transfer. But arsenic I explained before, the 20th pin is designed to transportation an electrical complaint betwixt transportation points.

This is due to the fact that a DisplayPort transportation was designed to let you to acceptable up things similar docking stations oregon adapters without needing a dedicated powerfulness adapter. However, arsenic of 2013, VESA mandated that each DisplayPort cables indispensable permission Pin 20 disconnected successful "passive" DisplayPort-to-DisplayPort cables owed to expanding reports of malfunctioning cords and devices caused by electrical feedback.
Why it's called the 'Death Pin'
When a cablegram is made incorrectly and connects Pin 20 end-to-end, this creates a afloat electrical circuit betwixt your GPU and display. That means that powerfulness is flowing betwixt them, which tin origin a big of problems, including:
- Short circuits: Both your show and graphics paper volition effort to provender powerfulness done the DisplayPort cable. And since they volition person antithetic voltage requirements, this tin rapidly overheat your cable, causing an electrical abbreviated oregon adjacent a fire.
- Backdriving power: Your PC operation oregon laptop tin beryllium afloat powered down, but if your show is successful standby oregon slumber mode portion plugged into a partition outlet, it tin trickle-feed powerfulness backmost into your computer. This tin origin each kinds of electrical problems that scope from eternally-spinning GPU fans to your PC not being capable to footwear up astatine all.
- Component failure: If a abbreviated oregon powerfulness backdrive is almighty capable oregon goes connected for agelong enough, it volition physically harm delicate components similar RAM sticks, graphics cards, and motherboards. Electricity likes to instrumentality the way of slightest resistance, and tin adjacent permission carnal grounds connected circuitry (melting, warping, etc.), bricking your system. Hence, the nickname.
Symptoms of a atrocious cable
If you fishy you've got a atrocious DisplayPort cable, determination are a fewer things to look retired for:
- Your PC won't aftermath from slumber mode oregon gets stuck successful a footwear loop
- GPU fans and motherboard LEDs stay connected aft shutdown
- Graphical artifacts and surface flickering
How to debar it
Thankfully, it's beauteous casual to forestall a catastrophe by keeping an oculus retired for authoritative VESA certification logos, which bespeak which brands person submitted products for VESA DisplayPort investigating to guarantee that designs bash not link Pin 20. Established, well-known brands similar Lenovo, Dell, and Anker each regularly taxable DisplayPort cables for verification.
And portion they whitethorn beryllium a spot pricier, it's worthy paying other for bid of mind. Lesser-known brands often chopped accumulation costs by skipping VESA testing, making it easier for defective cables to scope store shelves and shipping warehouses.
If you've got acquisition with electrical repairs, you tin usage a multimeter to cheque whether your cablegram has a afloat Pin 20 connection. If you get a speechmaking oregon acquisition immoderate symptoms of a poorly made cable, disconnect and flip it immediately, and regenerate it arsenic soon arsenic possible.
ZDNET's bottommost line
While astir newer graphics cards are designed with protective circuitry to forestall powerfulness backdrive damage, utilizing an uncertified cablegram inactive runs a important risk. Without VESA certification, it's astir intolerable to cognize whether Pin 20 is connected earlier you link it. And electrical problems tin origin severe, cascading harm astir instantly.
But choosing VESA-certified DisplayPort cables from reputable brands means a extortion warrant and keeps your workstation oregon gaming PC from becoming landfill fodder.
