PS5 Only Showing 4K60? Check the TV Port, Settings and HDMI Cable for 4K120
Quick answer: If your PS5 shows 4K at 60Hz on a 120Hz TV, first check the TV's actual 4K120 HDMI input, enhanced-format setting, the console's 120 Hz setting and whether the current game supports 120Hz. A replacement cable helps when the existing lead is damaged, too short or cannot reliably carry the required mode. The PS5's included cable is a valid first test; buying a cable cannot give a 60Hz-only TV a 120Hz input.
My PS5 supports 4K120. Why does my TV only show 4K60?
A 120Hz screen specification alone does not prove every HDMI input accepts a 4K120 signal. Check the TV's manual for the exact 4K120-capable port and enable its enhanced signal setting if required. On the PS5, open Settings → Screen and Video → Video Output; inspect the connected device information, resolution and 120 Hz Output. Try a game with a 120Hz mode: the home screen alone is a poor test of a game's 120Hz output. Connect directly to the TV during diagnosis so an AVR, switch, capture card or extension is not silently limiting the link.
Sony's PS5 video-output support guide specifically recommends checking the TV port, TV firmware, cable, intermediary devices, output resolution and transfer-rate setting for 4K120 issues.
Should I replace the PS5 cable for smoother gameplay?
Only if there is a cable-related reason. A suitable replacement carries a compatible 4K120 signal; it does not raise the game's frame rate or lower the console's processing latency by itself. Start with the supplied PS5 HDMI cable. If another cable is needed for a longer reach, a damaged lead or a repeatable link failure, look for the official Ultra High Speed HDMI Cable certification label and verify the QR code on the product package where present. HDMI Licensing describes this certified class as supporting bandwidth up to 48Gbps; the exact mode still depends on all devices. See the official HDMI cable certification explainer.
How do I choose the right MOSHOU cable?
For an ordinary PS5-to-TV setup with a short direct run, choose the shortest length that reaches without tension. These are distinct options, with differences you can verify before checkout:
| Situation | Matched MOSHOU option | Important check |
|---|---|---|
| Want the documented certification label | Certified Ultra High Speed HDMI 2.1 cable | Product page identifies 1m, 1.5m, 2m and 3m as label-included; do not assume the other lengths are certified. |
| Want a compact 1–3m premium cable | HD-068 certified, silver-plated HDMI 2.1 | Choose the exact 1m, 1.5m, 2m or 3m variant; check its label on arrival. |
| Need a lower-cost replacement | HD-065 48Gbps HDMI 2.1 cable | Listed for 4K120 on compatible devices; no certification claim is made here. |
Quick test before spending money
- Confirm the TV's actual 4K120 HDMI port in its manual and enable the required TV setting.
- Connect the console directly with its included cable.
- Set the PS5 output to Automatic or 2160p and enable 120 Hz Output where supported.
- Test a game that supports 120Hz and check the TV's signal information, not just its marketing refresh-rate figure.
- If the direct setup succeeds but a switch or receiver path fails, test the intermediary and its ports before buying another cable.
- If a known-good short cable works but the installed run fails, then investigate the longer cable or connector damage.
Frequently asked questions
Can an HDMI 2.0 cable give my PS5 4K120?
Do not select a cable advertised only for 4K60 for a 4K120 target. Use the included console cable or an appropriate Ultra High Speed HDMI cable and verify the TV port.
Do I need an HDMI 2.2 or 96Gbps cable for PS5 4K120?
No. HDMI 2.2-class bandwidth cannot add output modes to the PS5 or TV. Choose for the mode the entire device chain actually supports.
Why does 120Hz work at 1080p but not at 4K?
That can indicate a port, display mode, intermediary or link-bandwidth limit. Test a direct connection to the TV's specified 4K120 port.
Does the cable turn VRR on?
No. VRR needs support and enabling on the console, display and relevant connection path.
Will a more expensive cable improve picture quality if 4K120 already works?
A correctly functioning digital link will not gain finer image detail because the connector housing costs more. Upgrade for length, fit, a verifiable certification or to solve a repeatable link problem.
Is every length of a product called “Certified” certified?
Do not infer that. The MOSHOU main certified-family listing specifically calls out certification labels for 1m, 1.5m, 2m and 3m; check the exact selected variant and package.
Can I put an HDMI switch between the PS5 and TV?
Only if the switch and every port in the chain support the needed resolution, refresh rate and features. Test a direct connection first when troubleshooting.
Is 4K120 displayed in every PS5 game?
No. The game must offer a compatible 120Hz mode; output behavior also depends on the display and console settings.
Final answer
Fix the device and setting mismatch first. If you then need a new short HDMI lead, select the exact cable length and a product page that states the intended 4K120 mode. For buyers who want a documented physical certification label, use the identified 1–3m variants of the MOSHOU certified family.
Choose a 4K120-ready HDMI cable for your setup
Select the 1m, 1.5m, 2m or 3m certified-label version after confirming the TV's 4K120 port and the length required.
