Windows 10: Bigger non-native resolution is gone after updating to 20H2

Hello, after updating to 20H2 to get the new features which I already had for some reason, and no I'm not in Insider, I noticed the resouloution I used was gone. The resolution in question is 2560x1440, but now I'm stuck with 1600x900. The weirdest thing about this is that 2560x1440 isn't really an official resolution for this screen, but I like using the bigger resolution anyways because it gives me more room. I don't know how I can use my computer with so much smaller space. if you can help me get this resolution back, or something similar, that would really help.

Here's the specs of my monitor:
Name AMD RadeonTM Vega 6 Graphics
PNP Device ID PCI\VEN_1002&DEV_15DD&SUBSYS_84D2103C&REV_CC\4&98C7E10&0&0041
Adapter Type AMD Radeon Graphics Processor 0x15DD, Advanced Micro Devices, Inc. compatible
Adapter Description AMD RadeonTM Vega 6 Graphics
Adapter RAM 1.00 GB 1,073,741,824 bytes

Native resolution changed after the latest update

About a week ago, I decided to hit the check updates button and everything went normally, An update came, windows downloaded it and installed it. But after a long installation, things on my screen seemed bigger and a bit blurry, I have a few years old
full HD LCD monitor (connected with VGA) and AMD R7 265 GPU (with latest drivers). After I checked the screen options, I see windows showing me 1600x900 as my native resolution when it supposed to be 1920x1080. Currently, my windows have the update of version
1809 - IS 17763.437. I tried ''install the previous drivers'' option of windows and despite the recovery of my native resolution, my graphics card went crazy. Disconnected from the system every second repeatedly. When I find the chance, I turned back to the
latest drivers. Now I cannot play games or properly watch movies, videos because of my screen's limited resolution outputs.

Help! Windows 10 changed my resolution and can't see anything!!

Hi Etan,

We appreciate you for being part of Windows 10.

Monitors can support resolutions that are lower than their native resolutions, but text won't look as sharp and the display might be small, centered on the screen, edged with black, or stretched. It is recommended to set the screen resolution of the display
