My parents purchased a Samsung TV prior to me and I was stunned at the quality of it. The QLED 43’ 2026 is perfect for my family, it was a size larger than our last TV, but the features are 10x better.
We are happy with the new TV and it was quite simple to set it up. We are still trying to adjust the brightness and contrast, specially for scenes where there is a lot of sunshine
connectivity is horrible. I could not connect my Samsung TV to my Samsung sound bar using HDMI. even four calls to Samsung tech-support did not help.
No, I would not recommend this to a friend.

Response from Samsung USBy Samsung Specialist, August 5, 2026
samsteve,
Thank you for sharing your experience with HDMI connectivity on your QN70H TV. To help resolve the issue, please try the following steps: 1. Power off and disconnect all HDMI devices and cables connected to the TV. 2. Unplug the TV’s power cord from the wall outlet. 3. Press and hold the power button on the TV (not the remote) for at least 30 seconds to discharge residual power. 4. Reconnect the HDMI cables to their respective HDMI ports on the TV. 5. Plug the TV’s power cord back into the wall outlet and power the TV on.
Once reconnected, go to: Home > top directional key > Connected Devices > Connection Guide > Video Device > HDMI Troubleshooting. This tool will scan for HDMI connection issues and may help detect and resolve any problems automatically.
Please also ensure your TV is running the latest firmware, as updates may improve HDMI compatibility and stability. Go to: Settings > Support > Software Update > Update Now
When reconnecting your devices, make sure you are using a compatible HDMI cable. We recommend the following cable types for best performance: • High Speed HDMI Cable • High Speed HDMI Cable with Ethernet • Premium High-Speed HDMI Cable • Premium High-Speed HDMI Cable with Ethernet • Ultra High-Speed HDMI Cable
Additional tips: • Use an HDMI cable with a thickness of 0.66 inches (17 mm) or less. • Use cables shorter than 10 feet (3 m) for optimal UHD performance. • Non-certified or incompatible HDMI cables may result in no signal, a blank screen, or intermittent connections.
If the issue continues, please reach out to Samsung Customer Support at 1-800-SAMSUNG, (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available via the ‘Support’ link on our website.
