2015 Samsung 4k TV as a Monitor Set Up Guide

Zarathustra[H] said:
It's not that weird actually.

What you are perceiving is not necessarily the lag in the TV alone, but the overall lag of the entire system.

You know the sum of:
- Mouse lag
- USB system lag
- CPU/RAM etc. lag
- OS/Game Engine/Whatever lag
- transfer to video card lag
- video card render lag
- frame buffer output lag
- screen lag
- and probably others I haven't thought of.

These things are generally perceived as instantaneous by human beings as long as the TOTAL lag is ~100ms or below.

Now, with a monitor that uses ~40ms of lag, like the Samsung screens do, that leaves only ~60ms for everything else. At 60hz with vsync on on the desktop, the GPU uses another ~17ms, etc. etc.

it is easy for a problem with any individual component to push you over the edge.

This explains - more than some people just being more sensitive than others - why some people find the lag in the same screen acceptable or not so. For instance, if you use Crossfire/SLI you add a whole bunch of more input lag automatically. I can easily see how a bad USB driver or mouse might add some lag too, etc. etc.

The takeaway is simply that many many variables contribute to overall input lag, not just the screen, and you generally don't notice it until it surpasses the threshold, which for most people is about 100ms. You might have a high latency mouse or USB system all along, and never notice it, until you switch screens and now your total is above the threshold.

Thanks - makes sense.

I'm coming from 3 x Yamakasi Sparta Korean monitors w/o scalers (DVI only) so adding in 40ms is probably a pretty big jump for my system. There's probably also a bit of mental adjustment going on; I'm used to hitting a bezel and having a mouse appear on another monitor. On this TV... the mouse just keeps going, and going, and going. And the screen is curved so that's also a mental adjustment. :)

In a shotgun attempt I installed the new big Windows 10 update today, and found that my Logitech 502 had a firmware update, as well as moved the mouse to a USB3 port instead of USB2. Seems like something in that cocktail sauce of changes did make things a little bit better.

Will keep playing with it; I am starting to wonder if perhaps one of the Wasabi Mango's would have been better based on the input lag. It's unfortunate they are the same price as these Samsung's vs. a big discount like other Korean monitors.
 
I really, really want to love this 48JS9000 - but alas, I think I'm sending it back. It's a beautiful screen, and for ~$775 is pretty reasonable.

The mouse sensitivity/lag/whatever it is and keyboard delay... is just too annoying. If you are just browsing websites, or doing one thing here and there it's tolerable. But constantly switching between terminals, highlighting text, etc - it's really annoying. And the sensitivity part I see as well even in game mode so I'm not entirely sure it's input lag. I have to focus when I want to highlight text, which I've never had to do before on any computer monitor I've ever owned.

Going from 30" 2560x1600 DPI to this is also a little lower then I'd like.

May try to mess with it again later today to make a final decision - but it still seams like something is wrong. Maybe I just have a bad unit or something. It's just a huge, mind blowing difference moving back to my normal monitor.

I've never had these problems. I even moved a window across the border to one of my side screens so that half the window is on each screen, (Dell IPS monitors) and jiggled it back and forth and didn't see a notable difference in lag. The TV was maybe SLIGHTLY behind, but it was right at the border of perceptability to me, and not an issue.

This I agree with. The screen would have been better for desktop use had it been maybe 42-44" instead of 48". I've learned to deal with this though.
 
After a useless online chat with Samsung support I'm still puzzled. I have a Samsung UN48JS9000, the menu/support/contact samsung says it has firmware T-HKPAKUC-1460.4, BT-G/S. The latest firmware on the samsung website is "Upgrade File(USB type) (Firmware) ver. 1455.0 - All OS (MULTI LANGUAGE,1529.26 MB) released Jun 13, 2016"

How can my TV, which was made and boxed up last year, have a "newer" version of the firmware (1460) than the latest on the website (1455)? Samsung chat guy says mine is really 1455 and is the newest, which sounds odd. The TV menu for "software update" is ghosted so I guess I have the latest (or even something magically later than the latest available on the website.)

Anyone else with a JS9000 mind sharing their firmware version and if "software update" is greyed out or not?

BTW: I'm noticing no real input lag in GAME or PC modes on my JS9000, so I don't want to mess with the firmware unless I'm sure it will make something better. I know there is some, but compared to my old westinghouse 27" and even straight samsung, sony, and generic monitors (not TV's) I can't tell any difference. Maybe I'm just old :-/

They don't post every firmware release on the website.

In fact, they don't post MOST firmware releases on the website.

The only way to get most of them is to connect the TV to your network and search for updates.

Oh, I see. I guess since "software update" is ghosted out and can't be selected than I have the latest. I probably won't update ever anyway unless I have a problem with something or I'm certain there's some improvement (like maybe getting rid of those "ads" for apps like netflix and stuff that pop up occasionally.)

It shouldn't be greyed out even when you have the latest firmware. You should be able to select it and it will check for updates.

Where are you looking? It can be confusing.

You should be looking under Support -> Software Update

There is another one under System -> Smart Control Settings -> Firmware Update

This one DOES get greyed out when unavailable, but it is only for the remote firmware, not for the TV.

I'm on 1460 on mine right now. I casually keep up to date on my TV. Updates for this TV have always been positive for me with improvements, never any problems.

I usually don't keep my TV connected to the network though. I only plug it in once every few months and check for updates then unplug it again.

I don't trust network enabled embedded devices.

I guess I was mistaken or was looking at the firmware update instead of software update. It is not greyed out. It says I have 1460, which works great so I turned off auto update. Thanks.

Now if I could find a way to make the thing stop showing me popular apps and netflix icons at the bottom every 3rd time I turn it on that'd be great.

Otherwise a fantastic monitor.

If I remember you can disable loading the apps framework on startup. Should take care of this.
 
Amazing guide mate, it makes sense of all of the settings that were mind blowing me... This guide should be alot more available imo.

Great work

That sounds good -- any idea where it is in the menus? I've been searching to no avail.

Sorry, forgot to reply to this.

You want to go to the following location:

Menu -> Smart Hub -> Auto-Start Settings

Then set the items in this menu to "off".
 
so whats the new best 4k tv for pc gaming? Any out there that now does 4k 60hz at 4:4:4 low input lag? or anything better.
 
Back on page 6, I posted a message/video about an adjustable stand for our big 4K TVs used as monitors. I found something better. It's a pair of bars that attach directly to the TV without a big mounting bracket and platform. They were only $25 on Amazon.

https://www.amazon.com/gp/product/B01HE1IVNA/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

The bars are VESA compatible with lots of height adjustment flexibility. I set the top so it leaned forward just a bit. Very subtle, but definitely helps the viewing angle.

At first, I thought these bars were a bit flimsy, but once everything was put together it all formed a very solid, sleek, minimalist stand. Mine is set at the lowest height -- about .75 inches above the desk. I like it a lot better than the stand I posted about before.

I bought a Samsung UN40KU6300FXZA this weekend and had it set up out of the box with a first gen HDMI cable. I just got my new HDMI 2.0 cable and tried to follow the guide but I made everything look a lot worse. The menus are a bit different so I will have to iron it out. Pulling the zoom to 200% helped. WoW went from being pretty good to completely awful looking so I certainly have to keep working on it.

edit: I had to create a new account because my dcmix5 account was not getting the password reset emails and I didn't know what else to do

Seventyfive helped me tweak the settings and it looks great. I am super pleased with how crisp and clean this looks. The camera washes out the pic but in person it looks pretty impressive.

Glad it worked out. Please share what settings worked for you so another people can benefit.

I don't know what title this is, but I'm guessing it looked bad with my game mode settings in this article due to all the colored text. Game mode lowers input lag, but it sacrifices some quality due to dropping the chroma. It is usually only noticeable in small colored text.
 
Your settings were fine, it was just that the menus were different on my TV and it was so new to me that I was getting confused. It looks great...I am quite happy with it. Thanks for all the help in here!

I bought this stand for my Samsung UN40KU6300FXZA figuring it might work, but the fitment wasn't even close for desk height. I think I would need about 20 spacers for each of the 4 mounting holes to allow for bracket clearance near the bottom.

Strange... Mine screwed directly into the TV at the bottom. Added 4 spacers to each of the top 2 screws and the fit was perfect.

Do Samsung 120Hz TVs work at 60 Hz in game mode ?
Click to expand...

Yes. There is no way to get above 60hz @4k even with HDMI 2.0. The standard simple does not have enough bandwidth. You'd need the latest display port for that, and these TV's (like pretty much all of them) don't have display port.

Can you elaborate on "setting the top so it leaned forward"? Does this have tilt? I have a 43" KU6300 and I am not a huge fan of the built in stand, it's a little bit crooked and a little bit too high.

Thank you!!

I just added a few extra spacers (included) at the top 2 screws. Has the effect of leaning the top of the monitor a little over the bottom. Just helps the viewing angle on a bigger screen. This dual-bar stand will let you lower the monitor about three inches lower than the Samsung stand.

awesome suggestion, thanks dude!
 
Can anyone help me figure out why my screens resize to small boxes in the top left corner of my screen when the monitor wakes up after sleep?
 
Because when your monitor is off Windows sees no device attached at drops to the default res and re-arranges everything on you. There's a method of making that not happen floating around here.

I included Cyph's registry hack in the OP in this thread. Have you tried it?

I never needed it for some reason, but some people do.

And unfortunately, it never worked for me permanently. I tried a few times with Windows 7, but was never able to make it stick for long.

I haven't had the issue return since moving to Windows 10, which leads me to believe they might have changed the way they handle window positioning in the newer OS.
 
Yeah I tried the registry hack already but it didn't seem to have any affect. I thought I read about another solution in this thread but I didn't see it anywhere.
 
Got myself new KS7000 (american KS8000) - and I tried playing Devil May Cry on it - something felt really off.

It's probably a combination of moving from 27", 120 fps, near 0 input lag into 49", 60 fps, 50ms input lag but I had serious trouble trying to time my double jumps properly.

On the other hand I don't feel any such effects when using ps3/ps4 with it.

Yeah my 4k Samsung TV (not sure which model relative to this thread) vs my 144z XB270HU, TV feels lagged (frame processing + 60Hz).
