How do I Launch with a 4k Monitor?

[Filthy™]

is there a way to launch the game at a higher resolution than 1440? i tried going through the steam launcher resolution settings where you set windowed vs borderless and the other settings like that but it wont go anywhere near high enough to fit my screen.

The resolution is set in the fallout4prefs.ini file. Look for these lines -

iSize H=1080
iSize W=1920

Set everything else in the launcher, exit, then edit the inis.

The text size in the console will be halved. It will still be readable and it can be increased using a console command and/or ini settings. google it as I can't remember the exact way.

The ini files are in documents/mygames/fallout4 if not using a mod manager.

the game doesn't support ultra-wide, for this you'd need to use a mod

Super Ultra Wide Interface (32x9)

TRUBY9 ULTRAWIDE - FALLOUT 4
https://www.nexusmods.com/fallout4/mods/24630

if you're just trying to adjust the screen size manually,
Navigate to this location in your windows explorer:
C:\Users\%username%\Documents\My Games\Fallout4.

Locate and click on fallout4prefs.ini.

Find the following variables and edit them as shown.
They should be in the [Display] section

[Display]
bMaximizeWindow=0
bBorderless=1
bFull Screen=0
iSize H=1080
iSize W=1920

change the iSize H and W to the dimensions you want it to be.

This game will not run Ultra Wide resolutions.
Not going to gain anything in 4K visual wise either, I mean you can try the hi-res pack but read the reviews first. True 4K is 3840 x 2160, anything else is overrated crap.

So you want your game to be an even bigger buggy mess on a screen that it can't natively support?

>_> just reiterating what the above implies: while you can do this with mods or ini tweaking.... it will not change the fact that the game won't run well this way nor look all that good.

Run it windowed at a resolution big enough to be played and enjoyed without the hassles.

all i want is to not have to look at the game through the equivalent of a small porthole on my 42' main monitor lmao

thats the main issue is that it wont let me do that, i cant resize windowed mode and borderless mode dosent full screen it either

[Zekiran]

It SHOULD resize more likely with your ini alterations, it seems odd to me that it doesn't automatically if you're in windowed. I don't use windowed mode myself so I have no experience with fiddling with that.

Windows apps have settings that determine what behaviour the window supports e.g. resize.
It's a long time since I did windows programming but if the app didn't allow the behaviour you could add a flag to the launch properties which would do it. Google might have an answer.

But 4k should work if those 2 boxes in the launcher are left unchecked. I can set it natively in my launch settings.

A couple of facts about 4k -

1) cpu usage is the same for all resolutions.

Why is this so? The cpu prepares a wireframe which is resolution independent. The TWF console command toggles the wireframe on/off. A wireframe is composed of straightlines. Mathematically a straight line is simply defined as two points (X1, Y1, Z1 to X2, Y2, Z2). There is no difference for resolution.

The cpu also generates drawcalls for the gpu. Again the number of drawcalls is resolution independent. The number can be seen in ENB.

2) gpu usage is higher for 4k (obviously).

The load difference between 1080p and 4k is about 2 times. However if the gpu runs at 35% load for 1080p and increases to 70% at 4k, the framerate will be identical between 1080p and 4k. Why? Because the gpu has spare unused capacity.

My i7-2600 cpu from 2011 with a 1080ti from 2017 runs 4k without any issues at all. In current tech equivalent you can't buy a cpu that is as shot as an i7-2600 and a 1080ti is about rtx3060 level. Not much hardware required.

So if 4k is an even bigger buggy mess the odds are you have never tried it or your pc is even shottier than mine. Note that old tests from 2018 showed that amd/amd cpu/gpu combos performed 25-30% worse than similar intel/nvidia combos due weaker memory performance. That could be the cause the bigger buggy mess.

iv got it running at 2560 x 1080 but now the window that opens when trading / looting a container is too big and i cant see the top. anyone know how i alter the size of these boxes please?

Widescreen may need a mod. See the description for this mod.

I read once that dialog windows are written in an old product called Shockwave Flash, which was retired a few years go. Not sure if that's true but it would explain why they are wonky.

For 21:9 and 32:9 i recommend using Flawless widescreen. I have been using it for my two latest playthroughs. Works great. Just google it.

And about changing anything in the ini files, after you do change anything, don't go into the settings in the launcher. That might revert the changes that was made. So set up everything except resolution and fullscreen/borderless in the launcher settings, then go and change in the ini file.
