Missing a horizontal pixel width line when using NVIDIA RTX A1000

[m_skully]

I am missing a horizontal line of pixels when using my PC's video card in most ribbon view modes.

I just got off the phone with support and they said there is nothing that they can do and my video card isn't supported with AutoCAD, HOWEVER,

I specifically purchased this card / machine because it's "certified".

https://www.autodesk.com/support/system-requirements/certified-graphics-hardware/autocad

The support agent would not take my complaint past this point and told me to contact NVIDIA.

I don't feel this is MY problem to solve.

Is there someone's ear I can knaw on about this? 

The pic show a broken line, SW of the pick box and the horizontal crosshair disappears when lined up with it.

Have you installed the 2022.1.4 / 2023.1.6 / 2024.1.5 / 2025.1 Update yet? You never quite mention which year version you are running for some reason, nor make/model/specs of your new PC (or OS). ABOUT command in your AutoCAD/LT will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards.

If that did not help... Set GFXDX12 variable to 0 (that's a zero) then restart your AutoCAD/LT20??

If still no relief then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices.

Not sure anyone here can help you out, other than try an earlier or later AutoCAD/LT year version (Autodesk tweaks the graphics in each year version), then you yourself installing and testing newer and older drivers from

1) Your PC manufacturer website.

then

2) nVidia's website.

Best wishes.

@m_skully We purchased a Lenovo P16v for a mobile user here last year: let's just say we won't be replicating that purchase ever again. BUT... they are running LT2024.1.5 and they do not have the issues you've stated here.

I let them know to skip LT2025 this year.

Wow. Thank you. GFXDX12 to 0 did it! I should have asked here first instead of wasting my time with support!

What was wrong with yours?  My touchpad wasn't functioning and I almost sent it back.  Opened it up and the ribbon cable for the touchpad was not connected to the MB.   Not a good look.

Touchy touchpad (pun intended) but reseating the ribbon cable sorted it out, then the power brick stopped working and replacements were hard to find last year (they sent us two wrong ones first), plus it has a habit of freezing at very odd but infrequent times (no one can figure it out since we cannot repeat it on demand).

But the user loves the lightweight and performance.
