Screen overscan issues while running Xorg with a nvidia 1050ti GPU

sami63456 · 2024-08-02 02:45:37

To start with explaining my issue, i would like to say that i may not be the sharpest tool in the shed, so i am sorry for any foolish or otherwise ignorant mistakes or oversights i may have made or i am yet to make. I am running a nvidia 1050ti GPU with the latest drivers and my system is updated, and i am running xorg as mentioned in the subject. And the issue is that the screen is making me experience a bit of overscan, which is more than just annoying as it blocks the top and bottom polybar panels and also the sides of every program close to said sides of the screen.
I am displaying on a normal tv, due to me visiting family and this was the only spare screen they had laying around. it doesn't have any overscan related options and the closest thing it had was the aspect ratio options which were 16:9, 4:3, "zoom1", and "zoom2". none of the aspect ratio options fix the overscan, and i'm just using the 16:9 option (as for the latter --zoom 1 and 2-- it zoom into the screen creating even more overscan).

I have tried the nvidia settings and it doesn't seem to help, really. the underscan option isn't helpful because as i add to the value and the top panel appears, the bottom panel completely disappears. i'm not sure on how to use or edit the "underscan" and "ViewPortOut" options, but i guess i understand the rest. it's just that i don't think i understood the "underscan" and "ViewPortOut" options correctly.

I'm sorry for the long read, i'm not really new to linux but i haven't used it for a long time and i'm not used to messing with the display settings since my old display worked fine and so did my drivers.

I'm sorry for any shortcomings of the explanation on my part, please bear with me<3.

underscan "just works" here (on a regular monitor)
What happens if you underscan very aggressively by ~200px (the image should become much smaller and letterboxed)

The problem might be the particular Tv if it scans the signal and zooms it in, regardless of the settings - underscanning would then just end up making the image blurrier, but not smaller.

Edit: try one of the zoom modes on the tv, maybe they're staic multiplicators. Also The TV might discriminate inputs itr (what model is this?) and finally: it's the only attached output or is this a multihead setup?

i've tried the zoom mode 1 and 2. it's the same issue but it takes an even higher underscan for the top panel to appear completely. and i don't notice anything other than the zoom in.

not sure about the tv discriminating inputs about it's a "shark" LED-4310-S

it's the only attached output. through hdmi by the way. i would've bought a display port and checked if it might actual discriminate against which type of input it's receiving but it doesn't even have that.
only 2 hdmi ports, 1 VGA, and other analog ones.

i'd like to add that i'm thankful for you replying and trying to help me <3

EDIT: i should probably add that it looks as though it's off centered, which is why i say the underscan doesn't help. whenever i under scan it looks as though the screen just slides a bit to the bottom right instead of zooming out.

If the image stays the same sime bug just becomes increasingly blurry, the TV scans the input and upscales it to fit the non-black content.
In that case you're screwed (though you could still try the VGA input)

I can't really find the Tv online (let alone a manual for it)
