and is the drivers the correct version?
Use 470 proprietary not 470 propietary (tested).
The 470 tested has multiple issues. It's name is misleading.
cvt 2560 1440
2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz
Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
Modeline "2560x1440" 241.500 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
If flickering, you may need refresh rate to be 54.95, instead.

Check which driver you are using in the Software & Updates additional drivers tab... if it's is working, i'd prefer to back away slowly...
By the way, you can run
sudo apt clean && sudo apt autoremove
if you want to.

Everything else looked normal except this line ...
dpkg: warning: while removing fonts-symbola, directory '/usr/share/fonts/truety
pe/ancient-scripts' not empty so not removed
That is no problem- it left a font behind.

i tried those and now i get xrandr: --addmode requires two arguments. and i switched to the 470 proprierary driver and not the tested one.
i will take a look. also would some of my issue also be that my monitors are using display ports instead of hdmi?
that youtube video didn't work either. wonder why it won't see that my monitor can go higher resolutions? i had no problem in windows going to 4k resolutions.Linux won't do it for some reason.
Yep, that is useful information...
Display Ports and the cables leading to and from... Can be limited on their resolution.
Ok..I switched them to HDMI and same thing.guessing Linux doesn't support my monitors.
According to your first post, you are on a desktop computer. I'm not sure which motherboard you have. But one of the things that many people neglect to do, is install their chipset drivers. Your card may support 2K resolutions, and your motherboard may support pushing that resolution, but if their is a lack of chipset drivers, that may cause the issue.
