The platform map

Every TV brand hides network settings in its own menu, so this is the map first - then the click-paths.

Samsung Tizen

1. Press Menu (or Settings > General on newer models).
2. Open Network.
3. Choose Network Status.
4. Choose IP settings.
5. Set DNS Settings to "Enter manually".
6. Enter the provider's primary resolver as DNS Server.
7. Confirm with OK, run the connection test, close it.
8. Restart the TV [1].

Older Samsung sets and Blu-ray players may not support certain apps for hardware reasons - that is a model limitation, not a DNS problem [1].

LG webOS

LG splits its smart-TV line by operating system (webOS, Android TV, Google TV, Fire TV, Roku TV), and its brand guide links a setup guide for each [2]. On webOS: Settings > Network > Connection > your Wi-Fi connection > Edit > Advanced Wi-Fi settings, where the DNS server field accepts the custom resolver; newer webOS versions use Settings > General > Network. LG's own support pages cover the connection editing basics [10].

Google TV (Chromecast-style sets)

1. Open Settings, then Network & Internet.
2. Tap the WiFi network you are connected to.
3. Scroll down to IP settings.
4. Change it from "DHCP" to "Static".
5. Keep the IP address, gateway and prefix as displayed - change nothing there.
6. DNS 1 and DNS 2 now appear - fill both with the provider's resolvers [4].

Apple TV

On Apple TV 4+: Settings > Network > Wi-Fi (top entry) > your network > scroll to Configure DNS > Manual > enter the primary resolver > back > sleep the device > pull power for ten seconds [6]. On older Apple TV 1-3: Settings > General > Network > configure manually [6]. The power-cycle is not optional - Apple devices cache the old answer until sleep or reboot [6].

When the TV menu is the wrong route

Three platforms actively fight device-level setup:

• Fire TV: since OS 5.0.5, boxes and sticks ignore IPv4 DNS settings in favor of IPv6 when available - the documented fix is disabling IPv6 on the router so the stick falls back to your custom resolver [5]. The TV-side path (forget network, reconnect, enter DNS) still exists for wireless setups but is undermined by the same OS behavior [5].
• Roku: no manual DNS at all - router configuration is the only route, and some apps additionally require blocking 8.8.8.8 / 8.8.4.4 from the router [7]. Adding US channels also requires a Roku account located in the US, which Roku checks at signup - not a DNS setting, but the next trap in the same guide [7].
• Chromecast sticks on any TV: several generations ignore custom resolvers unless the router redirects Google's resolver traffic [8].

Register your IP address

Every guide above assumes the provider currently authorizes your household. That authorization is tied to your public IP, so it must be re-done whenever the ISP rotates it see the getting-started guide. Dashboard re-activation takes seconds; the permanent fix is the provider's Dynamic DNS updater covered in the router guide.

Verify it works

1. Dashboard marks. Unlocator's three green checkmarks are the fastest signal [8].
2. A geo-check service. Run one service you actually watch (our channel checker covers the popular ones).
3. The fallback test. Switch DNS back to automatic and confirm the catalog changes - that tells you the difference was the resolver, not caching or the app [8].

Common pitfalls worth knowing

• Half-updated state. New IP, old activation: apps load once, then geo-fail. Re-activate first, restart second [6][8].
• The wrong wrong. Green marks but broken apps is a coverage problem, not setup - check the provider's service grid rather than re-flashing the TV [8].
• Hotel TVs. Hotel Wi-Fi hands out its own resolver; changes made on a hotel TV can also persist badly on the next network. Configure your own device instead [8].

If all routes are blocked - ISP hub that hides DNS, TV that hides its menu - the pragmatic fallback is a router-in-a-box: an inexpensive travel router wired between the ISP hub and the TV, where you configure Smart DNS (or a VPN, comparison).

FAQ

Why does my Smart TV not have a DNS setting?

Several platforms hide it. Roku allows no manual DNS at all [7]; Fire TV since OS 5.0.5 ignores IPv4 DNS settings when IPv6 is available [5]; Chromecast ignores custom resolvers on many generations [8]. All three are solved at the router level.

How do I verify the setup worked?

Re-activate your IP in the provider dashboard first, then check its live DNS status (Unlocator shows three green checkmarks) [8]. Apps that still geo-error after green marks usually mean cached answers - restart the TV app or the TV itself.

Should I use the router instead of the TV menu?

If the TV menu exists and works, prefer it - it is one screen. The router is the fallback for locked or missing settings, and it also covers other household devices.

What is the Google TV static IP trick?

Google TV hides DNS behind static IP settings. You switch the WiFi IP settings to "Static", keep the IP/gateway/prefix values as shown, and then DNS 1/DNS 2 fields appear - fill them with the provider's resolvers [4].

Do I have to set both DNS slots on the TV?

Yes. Both slots point at the provider's resolvers; leaving the second slot on automatic can let the TV prefer an ISP server, which silently disables the trick [8].

My TV apps only show Netflix Originals. Is that normal?

Yes - some setups can only reach the globally available Originals catalog rather than the full home library. That is operator coverage, not your setup; check the service status in our provider comparison before blaming the TV.

What is the oldest TV that still works with Smart DNS?

Anything that still receives updates and accepts manual DNS - old Smart TVs and Blu-ray players often fail on hardware specs, not on DNS; operators note model limitations in their guides [1].

Does changing DNS break local apps on the TV?

No. Ordinary lookups resolve normally; only supported streaming domains get special answers. Local services behave as before.

The TV has IPv6 DNS listed. Do I need to do anything?

If the TV shows an IPv6 address for DNS, your IPv4 entries are being bypassed - disable IPv6 on the router (brand guides exist [5]) and the TV falls back to your custom resolver.

Can I use this on a hotel TV?

Not from the TV menu - hotel Wi-Fi hands out its own resolver and changes can persist badly on the next network [8]. On the road, configure Smart DNS on your own device and cast, or use a portable router.
