What are you trying to achieve with the upgrade? What to you use the computer for? Over all the GPU would be a good upgrade but I don't see much point in changing the motherboard and RAM.

Where are you seeing that only port 4 is 2.1?

This is what I found and to me that says they all are.

According to the specs list on that TV they all do.

From what I could see they all do. I also have a samsung tv and I don't remember having any issues with getting 4k/120 to work. Maybe check the settings to see if game mode is turning on when connecting to the Xbox. I can't remember if it needs that running or not but worth a try.

The one you have linked has both the power and data going through PCIe. Is there a reason why you want the data going through the SATA port on the motherboard? Can't say I've used something like that but have the data just go through the PCIe slot won't change anything as far as how it boots. EDIT: Never mind. I didn't look at it properly.

Slide it backwards first a little.

Never used a light beam before but by the sounds of it so long as you can get line of sight from one building to the other than there nano beams work really well. It would require power at the other end and a modem to broadcast the wifi but it would be the best option for a strong connection.

What issues exactly are you having. 34 devices isn't really that many especially if they aren't all being used at them same time. And depending on what the devices are they might not even have that much traffic going through them. Also depending on what devices you have and whether they are connect via 2.4 or 5Ghz I wouldn't think you would run out of channels.

Do you have XMP enabled?

Yep sure is. Usually only noticeable with large blocks of solid colour.

You'll mostly only see it in streaming things (YouTube, Netflix, etc). It's done to reduce the amount of data so it doesn't strain their servers. You shouldn't see it in games or anything else.

It's called compression.

Looking at it further the Pro also has options for higher tiered CPU's and 3 different options for the LCD display. The weights of the Pro would be the lowest spec'd ones and would probably change a little depending on the config. Basically the difference between the 2 at the end of the day is the non-pro has a couple of options and the pro is more flexible and allows you to choose what you want/need.

If you look at the specs for the Pro it list 3 different GPU options. One is Xe graphics.
