A device can support 4K output while a specific stream is only available at a lower resolution.
Use one test sheet
Put candidate services side by side for HD and 4K streaming. A device can support 4K output while a specific stream is only available at a lower resolution. Use the same device, connection, test time and definition of success.
Compare evidence
Compare the stream label, TV input mode and available bandwidth. Record the supplier link, total period cost, player charge and renewal route for each candidate.
Choose deliberately
Treating a marketing 8K name as proof every programme is delivered in 8K. If one service has an unknown condition, treat it as unknown until the supplier confirms it rather than awarding it the best score.
What to do next
Open the relevant brand page and check the original supplier information before ordering. For a technical issue, write down the device, player, connection and one reproducible example. For a price question, ask for the full charge in the currency you will pay.
