other uncertified boxes can only do netflix in SD.

Had you asked the question 2-3 months back, then Mibox S is ideal for you. It has Google Certification to give you FHD/4K Netflix with your 4K TV. It can also run official AstroGo app while you decide on your Astro account termination.

Sadly, today Mibox S has teething problem using AstroGo app. So if Netflix is your primary concern, then Mibox S is your choice provided you have a Netflix account.

My worries is that you think you are getting Netflix after the seller told you the box comes preinstall with a lot of Netflix movies & shows and you think you are buying the hardware with a Netflix account to use the Netflix app. Nope, it is not.

Tx6 4/32 should be in the RM150 region if buying from overseas. It is equally popular among Malaysian along with Tx3mini or Tx3. Read my few previous post in this thread comparing both these two.

Why these two Boxes are popular is because they can run official AstroGo app (Tx6 require manual unroot to use AstroGo). They can use Mobile version Netflix and give you max 540p quality pictures.

I think your 4K TV doesn't have Netflix installed. So make your choice wisely.
