Some GPUs or Monitors are not compatible with UEFI Mode in BIOS.

 

Did you recently upgrade your Windows to version 11 and set BIOS to UEFI Mode?

 

I had a similar issue with my Nvidia GPU card. In CSM Mode (Legacy) I receive video output to my 4k LG Monitor.

 

When I upgraded to Windows11 and  set BIOS to UEFI Mode I lost video output until Windows started loading.

 

But found out that my 2k Samsung TV does get video output during POST thus was able to configure BIOS even though on my 4k LG Monitor I had no video output.

 

It is possible that your GPU card has a BIOS that isn't compatible with UEFI mode in BIOS.

 

Also your RX580 2048SP is a rebranded RX 570 GPU card originally made to be sold only in China. 

 

NOTE: I would open a Support Ticket of your GPU card manufacturer and see if they have a newer BIOS that is compatible with UEFI mode.

i js got scammed bcs i got this pc refurbished and they told me that this is a rx580 8aGb

Technically whoever sold you the PC was correct since AMD did rebrand the RX 570 as a RX 580 by boosting the speed of the GPU card slightly.

 

AMD renamed that RX570 as a RX580 because I believe they increased the speed of the GPU card slightly. Here is a Tom's Hardware article from the past explaining about the AMD RX 580 2048SP GPU Card: https://www.tomshardware.com/news/amd-radeon-rx-580-2048sp,37933.html

AMD Sells Radeon RX 570 As Radeon RX 580 2048SP

AMD China has listed the new Radeon RX 580 2048SP on its website, which in reality is a Radeon RX 570 8GB in disguise.

At first sight, the Radeon RX 580 2048SP appears to be a cut-down version of the original Radeon RX 580, which comes equipped with 2304 Stream Processors. However, if you compare the specifications of the Radeon RX 580 2048SP and the Radeon RX 570 8GB, the similarities are clear. And no, your eyes aren't playing tricks on you. They are the same graphics card. The only true difference resides in the Radeon RX 580 2048SP's boost clock, which is 40MHz higher than the Radeon RX 570 8GB. But is that sufficient to pass it as another SKU? At least, we don't think so.

In AMD's defense, the company has every right to name its products however it sees fit. Technically, AMD isn't wrong. A Radeon RX 570 8GB is essentially a Radeon RX 580 with 256 less Stream Processors so calling it a Radeon RX 580 2038SP is valid in a way. We have to applaud AMD for its creativity. But some will think it's a shady move on AMD's part for pulling a fast one on less tech-savvy consumers.

At the time of writing, the Radeon RX 580 2038SP hasn't made its way to the Western Hemisphere yet. However, Chinese online retailer JD.com has the 4GB variant of the Radeon RX 580 2038SP listed for 1349 yuan, which translates to $195.03 and coincides roughly with the pricing of an aftermarket Gigabyte Radeon RX 570 4GB.
