Your 4k tv is lying to you: the hdmi port you’re using is throttling your ps5
Plug, play, panic: that washed-out HDR and stuttery 120 Hz you blame on the console is actually the bottom-left socket you never bothered to read. One glance at the back of any 2024 Smart TV reveals a row of identical HDMI graves; bury your Xbox Series X in the wrong one and you drop 30 Gbps of bandwidth before the boot logo even flashes.
Makers love the phrase “HDMI 2.1” on the spec sheet, but rarely tell you only two of the four ports actually speak the language. The rest remain fossilised at HDMI 1.4—10.2 Gbps, 4k 30 Hz, no variable refresh, no eARC, no future. A silent handshake limits colour depth to 8-bit, turns Dolby Vision metadata into mush and forces your £500 soundbar to fall back to optical tin-can audio. You feel it as “something off”; the metrics call it 4:2:0 chroma subsampling and 150 ms of lag.
How to spot the impostor ports in under ten seconds
Forget the marketing sticker on the bezel; manufacturers hide the truth on the plastic itself. Look for “4k 120” etched beside the socket, or a tiny “HDMI 2.1” embossed in grey on black—easy to miss under lounge lighting. No engraving? Check the silkscreen on the rear panel: ports labelled ARC/eARC are almost always the premium lane, because the TV’s chipset routes its highest bandwidth through the same controller that handles audio return. If the manual lists “@120 Hz” only on HDMI 3, believe it; the others are wired to an older repeater chip soldered to a cheaper PCB layer.
Cable complicity completes the scam. A £3 “high-speed” lead from the drawer might physically fit but tops out at 18 Gbps—fine for HDMI 2.0, hopeless for 4K 120 Hz with HDR. The only leads guaranteed to feed a RTX 4090 or PS5 full fat are certified Ultra High Speed HDMI: the packaging carries a QR code that validates on the consortium’s site. Anything else and the chipset throttles to 24 Hz “fallback mode” the moment the copy-protection handshake wobbles.

Why displayport never boarded the tv train
Monitors adopted DisplayPort 2.0—80 Gbps, no royalty, no fuss—years ago. TVs didn’t follow because the HDMI licensing cartel keeps patent fees buried inside every television’s bill of materials. It’s a cosy tax: brands pay pennies per port, consumers pay pounds in lost performance. The result is a connector monopoly that freezes innovation until the next revision cycle.
Engineers inside two major set-makers (requesting anonymity) told me the BOM difference between a quad 2.1 board and a mixed 1.4/2.1 layout is under $4. Yet product managers slice the spec to create tiered models; yesterday’s silicon repackaged as “entry 4K” sells for £150 less at retail while the panel—the actual expensive part—stays identical. Your eyes see judder; their spreadsheets see margin.
Fixing it is brutally simple: move the plug. Swap your console to the engraved port, enable HDMI Ultra HD Deep Colour in the TV’s submenu, and reboot the source. Latency drops by 18 ms, chroma jumps to 4:4:4, and the benchmark HUD finally locks 120 fps. One cable shuffle unlocks hardware you already paid for; the only thing you sacrifice is the smug certainty that every socket is born equal.
TV makers will ship HDMI 2.2 in 2025, promising 96 Gbps and AI-optimised compression. By then the playbook will be the same: three ports crippled, one unlocked, zero labelling that a human can read without a torch. Memorise the trick now or pay the ransom again next refresh cycle.
