Did Lenovo just support Thunderbolt 3 on the Legion y530?
On March 26th, Lenovo made a BIOS update available, version 8JCN50WW.
When going into the advanced BIOS settings, there's an option to enable 'Discrete Tunderbolt(TM) Support'. When enabled, there's a bunch of other options. I enabled some of them, but I'm not an expert at this and would rather not enable things of which I don't know the use case. After a restart, it's clear that something changed about the port, but I don't know if it's for the better since I can no longer connect an external screen to the USB-C port. Also, when the Thunderbolt option is enabled in BIOS, a yellow triangle appears next to the default graphics card (GTX 1050 for me) and it seems to stop working. I installed the y740 thunderbolt 3 drivers, but I have no Thunderbolt 3 devices to check if anything changed.
Could this mean that the y530 supports Thunderbolt 3? The USB-C port is the only connection without an icon above it and some speculate that it might be because it is a Thunderbolt 3 capable port, but wasn't enabled at launch. I can't seem to find out which component was used for the USB-C connection, but it might be the same as the y730 which is Thunderbolt 3-enabled by default.
Here's some pictures of the BIOS options (apologies for the quality): https://imgur.com/a/T5UKWMv
EDIT: After doing some more digging, I may have a possible explanation. This article reviews USB-C speeds on different laptops. There's a clear distinction between the laptops with normal USB capabilities and the Thunderbolt 3 ports. Except one: the Samsung Notebook 9 Pro laptop, which has an Intel “Alpine Ridge” Thunderbolt 3 chip but has the Thunderbolt 3 capabilities disabled. What remains is a high-speed USB connection through the USB-C port, just like the one found in the Lenovo Legion y530. If the Legion y530 has a similar chip, it could mean this BIOS update unlocks the Thunderbolt 3 capabilities of that chip.

Hey,i'd like to ask about something unrelated but I need help, did you updated your y530 to latest windows update and geforce updates? Do you got blurness some applications , games or even right clicking on a application running in the background has a blurry menu?, bought mine yesterday and facing that kind of problem, you can try (CPUID hwmonitor) and compare
I haven't experienced anything like that. I suggest searching around to see if other have this issue aswell, but it sounds to me like you have got a defective unit. Warranty should cover that.
So no blur any program what so ever using 125% display scaling?
If you experience no blurring at 100%, and only see it happen at 125% or something other than 100%. Then it's the windows 10 scaling issue. Nothing Lenovo can fix. There are a few fixes available, try searching for Windows 10 DPI fix.
