Got it — sounds like your PC is sending commands to your TV (like powering it on/off, switching inputs, or controlling volume). This usually happens because of HDMI-CEC or a similar feature. Here’s how to stop it:

Most TVs have an HDMI-CEC setting that allows connected devices (like your PC) to control them.

• On LG TVs it’s called Simplink (HDMI-CEC).
• On Samsung TVs it’s Anynet+.
• On Sony TVs it’s Bravia Sync.
• On Vizio TVs it’s CEC.

🔹 Go to your TV’s Settings > General > HDMI-CEC (name may vary) and turn it off.

Sometimes PC remote-control software (LG TV Plus, Samsung SmartThings, etc.) can make it seem like the PC is “controlling” the TV. If you installed one of these apps or drivers, disable/uninstall them.

👉 Can you tell me exactly what’s happening? For example:

• Does your TV turn on/off when your PC does?
• Does your PC remote/keyboard control TV volume?
• Or is it something else (like inputs changing automatically)?

That’ll help me give you the exact steps.

Ah okay, thanks — if your PC is making the TV’s on-screen menu pop up, that’s almost always caused by HDMI-CEC sending “remote control” commands over the HDMI cable.

Here’s how to stop it:

1. Turn off HDMI-CEC on your TV - Go into your TV’s Settings > General > HDMI-CEC (the exact name depends on brand): - LG → Simplink - Samsung → Anynet+ - Sony → Bravia Sync - Vizio → just “CEC” - Switch it to Off. - This stops your PC from sending “menu/remote” signals to the TV.

1. Check your PC’s GPU/driver settings (optional backup step) - NVIDIA: Open NVIDIA Control Panel > Display > Set up digital audio, uncheck your TV if you don’t need CEC/audio control. - Intel Graphics: In Intel Graphics Command Center, look for HDMI-CEC settings and disable. - AMD Radeon Software: Some models also expose HDMI-CEC settings → turn them off.
2. Use a CEC-blocking adapter (if needed) If your TV doesn’t give an option to disable HDMI-CEC, you can buy a cheap CEC-less HDMI adapter/dongle. It strips the control signal while keeping video/audio intact.

⚡ Quick test: After turning off HDMI-CEC, your TV should still show your PC screen normally, but pressing keys or starting your PC will no longer make the TV’s menu appear.

Do you want me to walk you through the exact steps for your TV brand (LG, Samsung, Sony, etc.)?

Im using a wired hdmi i just want to not control tv and just display my pc

Assistant: Got it 👍 — you’re just using HDMI for video/audio and don’t want your PC to send control signals to the TV.

Got it 👍 — you’re just using HDMI for video/audio and don’t want your PC to send control signals to the TV. That’s 100% the HDMI-CEC problem.

Here’s the cleanest way to fix it:

Every TV has a CEC toggle in its settings. The naming is brand-specific:

• LG → Simplink (HDMI-CEC)
• Samsung → Anynet+
• Sony → Bravia Sync
• Vizio → CEC
• TCL/Hisense → often just HDMI-CEC

📍 Go to your TV’s Settings → General → External Device Control (or HDMI settings) and set CEC to Off. → After this, HDMI will only carry video + sound, no menu/remote commands.

You can buy a cheap little adapter called a CEC-less HDMI adapter (around $5–10).

• Plug it between your HDMI cable and TV.
• It blocks the “control” pin in the HDMI port, so only picture/sound go through.

If you want to double-check on the PC side:

• NVIDIA Control Panel → Display > Set up digital audio → uncheck your TV.
• Intel Graphics Command Center or AMD Radeon Settings → look for HDMI-CEC and disable if it shows up (not all drivers expose this).

👉 Once HDMI-CEC is disabled (either on TV or via adapter), your PC will only display video/audio and can’t pop up the TV’s menus anymore.

Thanks for checking — on some setups the NVIDIA Control Panel doesn’t show the “Display” section (especially if you’re on a laptop or if your monitor/TV is handled by Intel iGPU).

But the good news is: you don’t actually need to change anything on the PC side to stop your TV menus from popping up. That’s entirely coming from HDMI-CEC, which is a TV setting, not a GPU setting.

1. On your TV, go into Settings. - Look for anything labeled: - Simplink (LG) - Anynet+ (Samsung) - Bravia Sync (Sony) - HDMI-CEC / CEC / HDMI Control (generic brands) - Set it to Off.

1. If your TV doesn’t have an option to turn CEC off → get a CEC-blocking HDMI adapter. They’re cheap ($5–10) and ensure your PC can’t send control commands, only video + audio.

💡 Once you disable HDMI-CEC (or use an adapter), your PC → TV connection will behave like a “dumb monitor.” It’ll only display video/audio, and the TV’s menu will never pop up by itself again.

👉 What’s your TV brand/model? I can give you the exact step-by-step menu path to switch off HDMI-CEC.

User: Well I can't find the settings and if it's plugged on i don't have control and if it plugged out i can't change anything

Assistant: Thanks — that helps a lot.

Thanks — that helps a lot. Since it’s an LG TV, the HDMI-CEC feature is called Simplink. That’s exactly what’s causing your PC to “control” the TV and open the menu.

Here’s how you can disable it (step-by-step for LG):

1. Turn on your TV (unplug your PC HDMI if needed so you can navigate).

1. On your LG remote, press the Settings (gear icon) button.
2. Scroll down and select All Settings.
3. Go to General.
4. Find Devices → HDMI Settings (sometimes it’s directly under General).
5. Look for Simplink (HDMI-CEC).
6. Switch it to Off.

- On some older LG models, Simplink is in Settings → General → Simplink (HDMI-CEC).

• On webOS models, you may also see Auto Power Sync — turn that Off too.
• After this, your PC HDMI will only show video/audio, and it won’t trigger menus or control the TV anymore.

If you can’t get into the menu while the PC is plugged in:

• Unplug HDMI first, go into TV settings, disable Simplink, then reconnect HDMI.

👉 Do you want me to pull up the exact menu path for your LG model if you tell me which one you have (e.g. LG C1, LG NanoCell, etc.)?

User: I don't have lg remote or see general options

Ahhh, that explains why you’re stuck 👌 — if you don’t have the original LG remote, you’re limited because most “basic” universal remotes or the TV’s side buttons can’t reach the deep menus like General → Simplink. That’s why you don’t see those options.

But you still have a few ways out:

- If your TV is a Smart LG (webOS, Netcast, etc.), you can download the LG ThinQ app (Android/iOS).

• Connect your phone to the same Wi-Fi as the TV.
• The app gives you full remote control, including access to All Settings → General → Simplink (HDMI-CEC).

- You don’t need the exact original. Amazon/eBay/Walmart sell LG Magic Remote replacements or even $10 universal remotes that support LG TVs fully.

• Make sure it says it supports Smart TV functions (not just volume/power).
• With that, you’ll be able to open All Settings and disable Simplink.

If you don’t want to mess with remotes/menus at all → get a CEC-blocking HDMI adapter/dongle (around $5–10).

• Plug it between your HDMI cable and the TV.
• It physically removes the “CEC control” pin in HDMI.
• Your TV will stop receiving any “menu” commands from the PC, regardless of settings.

⚡ Since you don’t have the LG remote and can’t find General settings, the fastest fix is:

• Either use the LG ThinQ phone app to disable Simplink
• Or buy a CEC-less HDMI adapter (cheap, plug-and-play).

👉 Do you want me to walk you through setting up the LG ThinQ app as a remote on your phone?

User: My tv cant connect to network

My tv cant connect to network

Assistant: Got it — thanks for clarifying 🙏.

Got it — thanks for clarifying 🙏. If your LG TV can’t connect to Wi-Fi or Ethernet, then the LG ThinQ app won’t work. That leaves you with only two solid fixes:

- You need a remote that can open All Settings → General → Simplink (HDMI-CEC).

• Even a cheap $8–10 universal LG-compatible remote will do.
• Search for “LG TV remote replacement” or “LG Magic Remote replacement”.
• Without this, you’re basically locked out of the deep menu settings that control HDMI behavior.

- This is a little dongle that plugs between your HDMI cable and TV.

• It physically cuts off the HDMI “CEC” pin, so your PC can only send video + audio.
• No menus, no TV control, nothing extra.
• Cost: about $5–10 (search for “HDMI CEC blocker” or “CEC-less HDMI adapter”).
• Example: - Lindy CEC-Less Adapter - BlueRigger HDMI CEC Blocker
• Completely plug-and-play.

🔒 Since you don’t have network access and no LG remote, the CEC-blocking adapter is your only way to immediately stop the PC from controlling your TV.

👉 Do you want me to find you a safe Amazon/eBay link to the exact adapter so you can just order one?

User: Is there anything I do on pc

Assistant: That’s a smart question 👍 — unfortunately, no setting in Windows or NVIDIA/AMD/Intel drivers can fully block HDMI-CEC …

That’s a smart question 👍 — unfortunately, no setting in Windows or NVIDIA/AMD/Intel drivers can fully block HDMI-CEC from the PC side, because:

• CEC is handled entirely inside the HDMI hardware.
• Your GPU just outputs video/audio — the control signal (CEC) rides along the HDMI pin automatically.
• Only the TV or a CEC-blocking adapter can stop it.

- Disable HDMI audio output: - Right-click the 🔊 sound icon → Sounds → Playback tab. - Disable your TV as an audio device. - This sometimes reduces HDMI control quirks, but usually menus still pop up.

• Use a DisplayPort → HDMI adapter: - If your GPU has DisplayPort, use a passive adapter to HDMI. - Many of these adapters do not forward CEC signals, so the TV won’t see control commands. - (Not guaranteed — depends on adapter model.)

If your LG TV’s Simplink (CEC) is still enabled and you can’t turn it off without the remote → the only 100% solution from the PC side is to use a CEC-blocking HDMI adapter.

👉 Do you want me to show you which DisplayPort→HDMI adapters are known to block CEC (so you might not need a dongle at all)?

User: The gear icon isn't pulling a different menu

The gear icon isn't pulling a different menu

Assistant: Ah, that makes sense now.

Ah, that makes sense now. On LG TVs, the gear ⚙️ button brings up the Quick Settings panel — which only shows things like picture mode, sound, and input. To reach the deep menu (All Settings) where Simplink (HDMI-CEC) lives, you need either:

1. The original LG remote (or a proper LG-compatible replacement remote)
2. Or a CEC-blocking adapter so you never need to touch the TV menus

- The Quick Settings menu (gear icon) ≠ the All Settings menu.

• Without a real LG remote, you can’t navigate into General → Devices → HDMI Settings → Simplink (HDMI-CEC).
• That’s why you don’t see the option to disable it.

1. Buy a cheap LG remote - Even the $8 universal ones on Amazon/eBay will open All Settings. - Once you have that, you can disable Simplink permanently.

1. Use a CEC-blocking HDMI adapter (no remote needed) - Plug it between your PC and TV. - Physically strips out the control signal, so your PC cannot trigger the TV menus. - About $5–10.
2. Use DisplayPort → HDMI adapter (if your PC has DisplayPort) - Many passive adapters don’t carry CEC at all. - Can be a free fix if you already have one.

⚡ So the reason the ⚙️ gear isn’t giving you what you need is because you’re only seeing Quick Settings — and without the proper remote, you can’t open the full settings tree where Simplink can be turned off.

👉 Do you want me to link you directly to a cheap LG-compatible remote or a CEC-blocker dongle, whichever you’d prefer?

Perfect 👌 that makes things much easier — with a proper LG remote you can now get into the full settings menu (not just Quick Settings) and turn off Simplink (HDMI-CEC), which is what’s making your PC “control” the TV.

Here’s the exact path on LG TVs:

1. Turn on the TV.

1. Press the gear ⚙️ button on your LG remote. - This opens Quick Settings.
2. Scroll down to the bottom and select All Settings (usually a three-dot “...” option at the bottom).
3. Go to General.
4. Select Devices → HDMI Settings (on some models it’s just “Simplink”).
5. Find Simplink (HDMI-CEC).
6. Switch it to Off.
7. Also set Auto Power Sync to Off if you see it.

✅ After this, your HDMI cable will only carry video + sound, and your PC will no longer pop up the TV’s menu or control it.

👉 Do you want me to give you the exact steps for your LG TV model (like LG C1, NanoCell, etc.)? That way you don’t have to hunt around.

Assistant: Perfect, thanks for the pictures 🙌 — now I can see exactly what menu system your LG TV has.

Perfect, thanks for the pictures 🙌 — now I can see exactly what menu system your LG TV has. That’s an older LG NetCast menu style (not webOS), and with the remote you showed, you do have access to the settings we need.

Here’s how to shut off Simplink (HDMI-CEC) on your LG:

1. Press the HOME button (on your remote it’s the one with the little house 🏠 icon between PICTURE and SOUND). → That’s the menu you showed on screen.

1. From that menu, go down to OPTION (bottom-left wrench icon). → Press OK.
2. In the Option menu, scroll down until you see Simplink (HDMI-CEC). → It may just say Simplink.
3. Highlight Simplink and set it to Off.
4. Also look for Auto Power Sync in the same area → set that to Off too.

- Your PC HDMI connection will only deliver video + audio.

• It will not trigger the TV’s menus or send remote commands anymore.

⚡ On older LGs, Simplink is always in the Option menu, not General → that’s why you couldn’t find it before.

👉 Want me to mark exactly which button on your remote to press first to get there, so you can follow along without confusion?

Assistant: Perfect 👍 thanks for the extra screenshot — you’re definitely in the LG NetCast interface the older style.

Perfect 👍 thanks for the extra screenshot — you’re definitely in the LG NetCast interface (the older style). You’re looking at the My Media section right now, but we need to back out and get into Option where the Simplink setting lives.

Here’s exactly what to press on your remote:

1. Press the HOME button 🏠 (middle row of your remote, between PICTURE and SOUND). - This is the menu you showed in your first screenshot (with Channel / Picture / Audio / Option / Network, etc.).

1. Use the arrow keys to move over to OPTION (bottom left, wrench icon). - Highlight it and press OK.
2. In the Option menu, scroll down — you should see a setting called Simplink (HDMI-CEC). - Highlight Simplink and switch it Off.
3. If you also see Auto Power Sync, turn that Off too.

✅ Once Simplink is off, your PC will still display normally, but it will no longer send “remote control” commands that make the TV’s menus pop up.

👉 Do you want me to circle on your first screenshot exactly where OPTION is so you can hit it directly with your remote?

User: That's what the home button does

That's what the home button does

Assistant: Ah, I see — thanks for clarifying 🙏.

Ah, I see — thanks for clarifying 🙏. On your LG remote, the 🏠 Home button is pulling up the tile launcher (with My Media, Inputs, etc.), but on older NetCast models, the deep settings like Simplink (HDMI-CEC) are not inside that launcher.

Instead, they live under the “Option” menu (the wrench icon you showed in your first screenshot). That’s the one you need to open.

🔧 Try this instead with your remote:

1. Press the HOME 🏠 button → you’ll see the screen with Channel / Picture / Audio / Time / Lock / Option / Network / Input / My Media / Game. (this is the screen in your first screenshot ✅).
2. Use the arrow keys to move over to OPTION (bottom row, wrench icon). - Highlight OPTION and press OK.
3. Inside Option, scroll down until you see: - Simplink (HDMI-CEC) → set to OFF. - If available, also set Auto Power Sync → OFF.

⚡ Once you do that, your PC will only display video/audio, and it will stop popping up menus or controlling the TV.

👉 Can you try pressing HOME → OPTION (wrench) right now and tell me what shows up in that menu? That’s where Simplink should be hiding.

User: I don't have an option selection and the blue button just gives divX reg.

I don't have an option selection and the blue button just gives divX reg. Code

Assistant: Thanks for sticking with me through this — your photos are super helpful.

Thanks for sticking with me through this — your photos are super helpful. What you have is an older LG TV (pre-webOS, pre-NetCast HD). On these, the menus are a bit different and sometimes Simplink (HDMI-CEC) isn’t under Option like on newer ones.

On many of those models:

• Simplink is its own button on the remote (sometimes labeled SIMPLINK).
• If the remote doesn’t have that, it may still be buried under INPUT or SETTINGS (gear icon) → Setup / Options.
• And yes, the blue button pulling up the DivX registration is normal on those older sets, not what we need.

🔧 Things you can try with your remote:

1. Press INPUT on your remote. - Look in the bottom or side of that menu for Simplink. - If it appears, toggle it Off.
2. Press Q.MENU. - Sometimes CEC toggles were stuck in the quick menu on this generation.
3. Press SETTINGS (gear ⚙️). - If it only gives you Picture/Audio basics, look for a submenu called Setup or Option. - Simplink is usually in there if available.

⚠️ Important

Some of the older LG TVs did not allow turning Simplink off in the software menu at all — they assumed you’d use the SIMPLINK button remote. If that’s the case for your model, then the only guaranteed fix is:

• Use a CEC-blocking HDMI adapter (a $5–10 dongle that strips the control line), or
• Swap to DisplayPort → HDMI adapter from your PC if it has DisplayPort (often these don’t pass CEC).

👉 Quick check: Can you press the INPUT button on your remote and tell me if you see “Simplink” at the bottom of that menu? That’ll tell us right away whether this model lets you disable it in-menu.

User: Input just changes between hdmi and tv

Input just changes between hdmi and tv

Assistant: Got it — thanks for confirming 🙏.

Got it — thanks for confirming 🙏. That tells me your TV is one of the simpler/older LG models that doesn’t expose a Simplink toggle in the on-screen menus. On those, HDMI-CEC is always on in the firmware, and the only way LG intended people to control it was with a remote that had a dedicated SIMPLINK button (your remote doesn’t).

That’s why:

• INPUT only switches sources, no Simplink option.
• OPTION or General doesn’t exist in your menus.
• Blue button just shows DivX registration.

✅ What this means for you

Since you can’t turn Simplink off in software, you only have two real fixes left:

1. CEC-blocking HDMI adapter - Little $5–10 dongle that sits between your HDMI cable and the TV. - Physically disconnects the CEC pin, so your PC sends only video + audio. - 100% reliable and plug-and-play. - Search Amazon/eBay for: - “HDMI CEC blocker” - “CEC-less HDMI adapter” - Examples: Lindy CEC-Less Adapter, BlueRigger HDMI CEC Blocker.
2. Use DisplayPort → HDMI adapter (if your PC has DP output) - Many DP→HDMI adapters don’t pass through CEC at all. - Can solve the problem without buying a dedicated CEC blocker. - Not guaranteed — depends on the adapter model.

⚡ Bottom line

Because your LG TV doesn’t give you a menu option for Simplink, the CEC-blocking HDMI adapter is the cleanest and fastest way to stop the TV menus from popping up.

👉 Do you want me to find you a couple of safe Amazon links for cheap CEC-blocker adapters, so you can just order one and be done with it?
