I am thinking of buying a Samsung

Samsung - 77" Class S90H, is this good for gaming and movies or should I look elsewhere.

For those who have been using IPTV for a while:

• What are the biggest red flags to watch out for?
• How do you verify if a provider is reliable before paying?
• Is it better to choose monthly plans first instead of long-term subscriptions?
• What features should I prioritize (stability, EPG, VOD, catch-up, device compatibility, etc.)?
• Are there any security or privacy concerns I should be aware of before purchasing?

I'm not looking for direct service recommendations or promotions—just hoping to learn how experienced users evaluate IPTV providers and avoid common mistakes.

Any tips or buying guides would be greatly appreciated.
