Probably easiest for me to break your post down so I can answer what I know or point you in the direction of those who know better...

I have no problem playing YouTube from the SEK-3500 but as far as the Tizen webbrowser goes, yeah it suck and for that reason I have an 4K HTPC hooked up to my main setup. It is also useful using the YouTube web interface where you can search for 4K videos much easier and filter your results to only include HDR (which the SEK-3500's YouTube app is not capable of since it does not support VP9.2).
I have a Chromecast Ultra in our bedroom that supports YouTube 4K HDR and enjoy my Apple TV 4K on my main setup in the living room for iTunes movies and the thousands of apps it supports.
The "Smart" in Smart TV can pretty much be replaced by a $100 gadget these days which can be easily replaced if technology changes without the need to upgrade your TV to have the latest and greatest!

As i mentioned I'd like to watch 4k/60 and don't know why Y520's HD Graphics 630 does not want to set to 60 Hz (its specs allow), the second Nvidia gtx 1050i can't be switched to.
So with an admissible lag i can set
- Game mode 4k/ 30p. The drawback, scattered movement of mouse etc, 60 Hz would solve. Youtube seems ok
- Game mode 1080/ 60p. The best lag. Do not scale to 4k ok, bad text... as an observation.
- Device Type: PC mode 1080/ 60p. Lower refresh rates increase lag a lot, but some of them allow AMP, like 30p. Do not scale to 4k ok.
I am not a gamer so not something I have any expertise in other than referring you back to the NVidia guide I posted offering suggested settings where the author suggested having both Device Type: PC and the Game mode turned on. He indicated he got better results this way.
Not sure what the limitations of your graphics card are but here are the specs of my HTPC...
Acer Aspire GX-785-EB11
Intel® Core™ i7-7700 3.6 GHz;
Quad-core - NVIDIA® GeForce® GTX 1060
...where the graphic settings allow me to set mine up to 4K at 60Hz with Color Depth at 8, 10, or 12 bpc (where I have mine set to 10 bpc) and Color Chroma of YCbCr 4:2:2 as shown in the thumbnail below which comes in very handy for watching 4K HDR content (e.g. Netflix; YouTube).

Color space to JS9000 if set to auto it won't set to Native.
Picture options> HDMI black level> Normal - for more details, shadows of grey
AMP why not always smooth
Glad you found the template useful.
For your next few comments I am going to direct you to a guide developed by
, one of our very knowledgable experts when it comes to the JS
as well as the SEK-3500 settings:
JS Series Picture Settings (General Guide)
As you can see originally we had to set the Color Space
to Native but firmware 1460.4 issued in August 2016 “the behavior of the "Auto" setting has been fixed and is now properly tracking the wider Rec.2020 Color Space. Therefore, you can now simply leave this setting on "Auto" for both SDR and HDR content“
Just so you are aware its not so much that I chose HDMI Black Level
to Auto, rather as my particular devices go this option is greyed out thus the reason I display ‘Auto’’ in a grey font in my settings template. This is due to the fact that when a YCrCb signal is detected, the "HDMI Black Level" setting will be unavailable ("grayed-out"). If you Search this Thread
you will find a number of similar posts saying it is greyed out for other users as well and this would be the case for most devices (except perhaps computers or a game console if it is set to RGB output.
Finally, Auto Motion Plus [AMP)
. You ask why not always Smooth. So I’ll ask you — why not always Clear?
More commonly known as Soap Opera Effect
(SOE) where some people don't notice it, some don't mind it, and a few even like it... whereas Tom Cruise has created a video telling us why we should turn it Off at least while watching movies which might have me revisiting this setting especially on inputs I use primarily for watching 24fps movie content such as Netflix, iTunes movies, or UHD Blu Rays (e.g. my Apple TV 4K and my UHD Blu Ray Player)!
If you review the guide you will see this is a personal preference where some even turn on Custom and set a secret recipe of Judder and Blur. Like
, for the most part I “prefer” Clear and have found the FIFA in France to flow very nicely on the Arris 4K Set Top Boxes provided by my cable company which output all content at 3840 x 2160 @ 60Hz.
Hope the above Guide helps and if you scroll to the bottom of
's post you will find links in his signature to a number of other useful documents... whereas other times a Search this Thread
or a Google
search may be in order (like I had to do while answering this post) since most of this stuff has been discussed many times over in the past 4 years since the SEK-3500 was introduced and some long before that and I have probably forgotten more than I ever knew.
