Moderators, I looked at all the forums and felt this was the most appropriate to post this in, but feel free to move it if that's not the case.
I just purchased a VIZIO V405-G9 TV (supports 4K and HDR) yesterday and plugged it in right away anxious to experience 4K, since it's my first 4K set. However, no matter what I tried, the highest resolution I saw in the top bar (which you get when you switch inputs or press the Info button) is 1080p. I tried all of the following:
- 4k content on the Netflix app through SmartCast (I pay for the Netflix Ultra HD plan).
- 4K content on the Netflix app through the 3rd gen FireTV (the square dongle) connected to HDMI1, which supports 4K.
- 4K content on the Prime Video app through SmartCast (I have a Prime account).
- 4K content on the Prime Video app through the FireTV.
- The 4K Pluto TV channel through SmartCast.
- The 4K Pluto TV channel through the FireTV.
According to the info bar on top, everything seems to stream at 1080p, 720p and even lower and I have yet to see the HDR icon I am supposed to see when HDR is enabled.
However, I then thought of bandwidth and googled what's required for 4K. I read you need a minimum 25 mbit/sec download for a steady, clear 4K stream. Right away, I used the TV menu to check the speeds I am getting on the TV. Average is 2.5 mbit/sec, but it varies constantly and wildly from 200 kb/sec to 5 mbit/sec; it just does not go above that. I found that rather strange, since I have a Netgear Orbi RBR50 router with an RBS50 satellite, which I even placed right next to the TV... No change. I even plugged the TV into the satellite via RJ45 cable... No change. Same speeds whether the satellite was further, next to the TV or wired. I even made sure through my Orbi app that the TV was connecting to the satellite, not the router, which is 2 rooms away. At the same time, just to make sure my network was working as expected, I used 2 different devices (one of them being my cell phone) in the same location to test speeds and every reading was above 90 mbit/sec, some as high as 120 mbit/sec.
So my question and concern are around the WiFi adapter/drivers of the VIZIO TV. Why am I not getting anything above 5 mbit/sec when my router is capable of so much more? If the TV is not capable of more, how can it even stream 4K video?
I do have the very latest software version, which was installed during initial setup. I checked a couple of times.
Thanks in advance for your feedback.
