Why does your PS5 show a black screen on one TV but work fine on another? It’s not broken — it’s likely an HDMI handshake issue. And trust me, you’re not alone.
Thousands of PS5 users run into this exact headache: black screen, flickering, or that dreaded “No Signal” message. The problem? Your console and TV aren’t syncing up properly, and it’s usually fixable without buying anything new.
In this guide, we’ll walk you through how to fix PS5 HDMI handshake issues step by step. Plus, we’ve pulled real solutions from Reddit threads and gaming forums, so you’ll get more than just generic advice.
What is an HDMI Handshake?
Ever turn on your PlayStation 5 and nothing shows, the screen stays black, or it notifies you of No Signal? That’s often an HDMI handshake issue.
Let’s first understand what an HDMI handshake is. It is a digital communication process that happens when your PS5 connects to a TV or monitor. During this procedure, both devices exchange essential information, including supported resolution, refresh rates, color formats, and copy protection protocols. Think of it as a digital introduction, where PS5 tells TV what it can send and TV responds with what it can receive.
Why HDMI Handshakes Fail on PS5
The PlayStation 5’s advanced capabilities can sometimes overwhelm older or incompatible displays. Common causes include:
- 4K/HDR compatibility issues between the PS5 and older TVs
- HDCP (High-bandwidth Digital Content Protection) conflicts
- Faulty or inadequate HDMI cables that can’t handle the PS5’s bandwidth requirements
- Firmware bugs in either the PS5 or your display device
- HDMI-CEC interference is causing communication errors
Signs Your PS5 Is Having an HDMI Handshake Issue
If your PS5 and TV aren’t syncing properly, you might run into these HDMI handshake issues:
- A black screen appears after powering on the PS5
- Intermittent flickering or the screen going in and out
- “No Signal” error message on your TV
- Green screen or distorted colours
- Audio working but no video (or vice versa)
- Display working initially, but failing after HDR content
How to Fix PS5 HDMI Handshake Issues (Quick Fixes)
If your PS5 is giving you a black screen, flickering display, or the dreaded “No Signal” error, chances are your console and TV aren’t completing a proper HDMI handshake. Here’s a simplified guide to fix it — step by step, no tech jargon needed.
1. Check Your HDMI Cable & TV Port
Cheap cables often fail. PS5 is built to push high-quality video, 4k at 120Hz with HDR. That needs serious bandwidth. If you are using a low-grade or older HDMI cable, especially one not designed for HDMI 2.1, the handshake can fail before it even begins.
Make sure your HDMI cable has:
- Certified Ultra High Speed HDMI label
- 48 Gbps bandwidth support
- Under 6 feet (2 meters) for a strong, clean signal
- A trusted brand with solid reviews (don’t risk no-name cables here)
Testing Your Cable:
- Connect your PS5 using the original Sony HDMI cable
- If the issue persists, try a different certified HDMI 2.1 cable
- If your current cable is long, try using a shorter one (under 6 feet is best)
2. Power Cycle Both Your PS5 and TV
Sometimes, a simple reboot clears out HDMI handshake errors. Here is how to do it right:
- Fully power off the PS5 (don’t use Rest Mode)
- Turn off your TV or monitor
- Unplug both devices from power for 30 seconds
- Plug your TV in first and turn it on
- Once the TV is fully on, plug in and power up the PS5
This clears cached HDMI sync issues. Both your console and TV store temporary data about connected devices. If that cached data becomes corrupted or outdated, it can prevent successful communication. Power cycling clears it out and forces a fresh handshake attempt.
3. Enter Safe Mode & Adjust Display Output
Seeing a black screen? Safe Mode might be your way back in.
How to Boot into PS5 Safe Mode
- Turn off your PS5 completely
- Hold the power button for 7–8 seconds (wait for a second beep)
- Connect your controller via USB
- Press the PS button
Once you’re in, try the following:
Lower the Resolution
- Switch from 4K to 1080p
- Drop the refresh rate from 120Hz to 60Hz
- Lower settings = fewer problems, especially on older TVs
Adjust HDCP Settings
- Go to Settings > System > HDMI
- Change from “Automatic” to HDCP 1.4
- Some displays don’t work well with HDCP 2.3 — this tweak helps
Disable HDR (Temporarily)
- Turn off HDR in your display settings
- Once the handshake is stable, you can turn it back on later
Turn Off HDMI-CEC
- Disable HDMI Device Link in system settings
- CEC can interfere with handshake communication
- This prevents automatic device control conflicts
4. Try a Different Display or HDMI Port
Test with another TV or Monitor
If you’ve done all the above and still no luck, try plugging your PS5 into a different screen. If it works there, your original TV is the issue, not the console.
Optimal HDMI Port Selection
Try these ports in order of preference
- HDMI 1 – usually the most stable
- eARC/ARC ports (typically HDMI 2 or 3)
- Gaming Mode ports (sometimes labeled “Game” or “PC”)
- HDMI 2.1 ports – if available, always a good bet
5. Use a Splitter or AV Receiver (Advanced Fix)
If your TV won’t cooperate — even with the right cables — it might be time to add an extra layer. Some TVs don’t handle the PS5’s HDMI signal well. A splitter or AV receiver can act as a buffer, managing the handshake process more reliably than a direct connection.
EDID Emulator Tools (For Advanced Users)
These little devices store and send consistent display info to your PS5 — kind of like a translator between your console and TV. It is great for bypassing handshake failures caused by bad or corrupted EDID data.
Using an Audio Receiver to Bypass Bad HDMI Implementation
Connect your PS5 to an AV receiver, and then connect the receiver to your TV. The receiver handles the complex handshake process and often provides better compatibility than a direct TV connection.
Bonus Fixes Reported by the Community
Sometimes, the best solutions come from the people who’ve been through it. Reddit threads, GameFAQs forums, and YouTube comments are full of creative workarounds that have helped players get their PS5 displays working again. Here are some of the most talked-about community hacks for how to fix PS5 HDMI handshake issues:
The “HDR Toggle” Fix
Many users have found that cycling HDR settings can jolt the handshake process back to life. Here’s how it usually works:
- Turn HDR on in your PS5 display settings
- Play something with HDR — like a movie or HDR-enabled game — for a minute
- Then turn HDR off
- Finally, turn it back on again
This back-and-forth seems to “reset” the HDR handshake between the console and TV.
The “Resolution Cycling” Method
Still stuck? Try this simple trick:
- Set your PS5 to 1080p
- Power your TV off and back on
- Switch your PS5 display settings back to 4K
- The fresh handshake often clears out stubborn sync problems
TV Brand-Specific Fixes
Some handshake bugs come down to how your TV handles HDMI — and yes, each brand has its own quirks. Here are a few brand-specific tips that have worked for others:
LG TVs
- Temporarily disable “HDMI Ultra HD Deep Color”, then turn it back on
- Make sure your webOS firmware is up to date
- Try setting the HDMI input to “PC Mode” for better signal stability
Samsung TVs
- Start by turning Game Mode off, let the PS5 connect, then turn Game Mode back on
- Disable “HDMI UHD Color,” then slowly re-enable advanced features after a successful connection
- If you use a One Connect Box, check for firmware updates — handshake bugs often stem from outdated firmware
Vizio TVs
- Turn off “Full UHD Color” in the HDMI settings
- Use HDMI Port 1 — it’s usually the most stable on Vizio sets
- Update your SmartCast firmware via the TV’s system settings
Don’t Skip Firmware Updates
HDMI handshake bugs are often software-related, not hardware flaws. Console and TV makers are constantly patching compatibility issues. Here’s what to check:
- On your PS5: Settings > System > System Software > Update
- On your TV: Go to Settings > Support or About to check for the latest firmware
- For PC monitors or AV receivers: Check the manufacturer’s site for HDMI driver updates
FAQs
Q. Why does my PS5 work on one TV but not another?
Some TVs have limited HDMI compatibility. Your PS5 may work perfectly on one TV but not another due to differences in HDMI controller design, firmware support, or HDMI version compatibility. Older TVs might not fully support HDMI 2.1 features like 4K at 120Hz or advanced HDR formats, while some newer TVs can still have bugs in their firmware. If the TV’s HDMI implementation can’t handle the PS5’s advanced signal, the HDMI handshake can fail, resulting in a black screen or flickering.
Q. Does enabling HDR or 120Hz on PS5 cause HDMI handshake issues?
Yes — both can contribute to handshake failures. HDR and 120Hz gaming significantly increase the bandwidth and complexity of the HDMI signal. Some TVs or cables can’t handle this reliably, especially if they’re older or not rated for HDMI 2.1. If you’re experiencing screen flickering, “No Signal” errors, or blackouts, try disabling HDR and reducing your refresh rate to 60Hz in your PS5 display settings. This can often restore a stable connection.
Q. Can HDMI-CEC cause PS5 display or signal issues?
It can, especially with multiple connected devices. HDMI-CEC (called HDMI Device Link on PS5) allows devices like TVs, soundbars, and consoles to control each other through a single HDMI connection. However, this feature can sometimes lead to conflicting commands or signal interference, which may disrupt the HDMI handshake. To avoid this, go to Settings > System > HDMI on your PS5 and disable HDMI Device Link.
Q. What’s the difference between HDCP 1.4 and HDCP 2.3 on PS5?
HDCP 2.3 is newer but stricter — HDCP 1.4 is more flexible. HDCP (High-bandwidth Digital Content Protection) is used to prevent content piracy, but it can sometimes cause compatibility issues between your PS5 and TV.
- HDCP 2.3 supports modern 4K/HDR content but may not work well with older displays.
- HDCP 1.4 is more universally accepted and can help resolve handshake issues.
To change this setting, go to Settings > System > HDMI > Enable HDCP, and switch from “Automatic” to “HDCP 1.4”.
Final Thoughts
HDMI handshake issues on the PS5 are frustrating, but in most cases, they’re completely fixable at home. In most cases, it’s not your console or TV that’s broken—it’s just a communication glitch between the two.
If you’re searching for how to fix PS5 HDMI handshake issues, start with simple steps: check your HDMI cable, power cycle both devices, or tweak display settings. Most problems clear up with a little patience and the right approach.
However, if the issues persist, don’t hesitate to reach out to PlayStation Help Center. Sometimes, a firmware bug or deeper compatibility issue may need expert support.
