Recently I've upgraded my PC and switched it on to find one of my WQHD monitor is displaying max of 2048 x 1152.
Other one is working fine as 2560 x 1440 though.

These 2 monitors workekd as 2560 x 1440 in my previous old copmuter using the onboard gfx.
Then i swap to this brand spanking new PC and I get the bung eye.

What could possibly be wrong to have this effect?
Motherboard is MSI 450B Tomahawk MAX II using 3400G onboard graphics (AMD Vega 11)

What remained the same from previous build is the monitors and HDMI cables.
I am using one of the monitor via HDMI (Which works fine) and DVI (Which isn't fine). This was the case in my old PC as well

Could I get some help to have both on 2560 x 1440 please?

According to the motherboard's product page, the resolutions are supported off the I/O panel. You might want to see what BISO version you're on at the time of writing. Also, what version of Windows 10 are you on at the time of writing? Also, by new PC, I'm assuming you didn't need to migrate the old OS and storage drives from the older platform correct? That the new system had a clean install of OS?

Swap the monitors "position". Determine if the problem follows the monitor or stays with the connections being used.

Verify that the correct drivers are installed for the onboard graphics.

Double check all video/graphics configuration settings. Be sure that you "Save", "Apply", or "Ok" as applicable to make the changes permanent.

If that does not help or work - then the drivers may be corrupted or buggy.

Manually download via the manufacturer's website. Reinstall and reconfigure.

No third party installers.

Checking the BIOS version, it is "American Megatrends Inc. H.30, 30/11/2020"
Using Windows 10 Enterprise 10.0.19043
It's a brand new PC with brand new everything inside. New OS installs etc. I did port over 2tb E: drive, which is for data only. So I don't see any issues with that.

One thing I forgot to mention is that I am using HDMI to DVI adaptor for the one that is plugging into the DVI port on the mobo.
So:
Monitor 1 -> HDMI cable -> HDMI port on mobo (2560 x 1440)
Monitor 2 -> HDMI cable -> DVI adaptor -> DVI port on mobo (At reduced resolution of 2048 x 1152 )

I tried swapping the HDMI cable at the mobo ports and the issue is following the DVI port.
But I don't think it is an issue with the adaptor and cable because it was all working fine in the old PC at 2560 x 1440.

The display drivers installed: AMD Radeon(TM) RX Vega 11 Graphics v27.20.21002.112 date: 13/04/2021

Not sure if I can set anything up in BIOS for the displays... I'll try having a look

Oh dear... I thought all DVIs can handle up to 2560 x 1440.
I must have purchased a dinosour mobo!

Is there a way around this to have both monitors displaying at 2560 x 1440?
Display Hub via USB maybe? Never tried them before so not sure what it is like

DVIs yes ... but not all mobo outputs have the same stats. That's very 'personal' thing for each model.
One thing you could try is to lower frequency from 60 Hz to 30 Hz. That SHOULD let you use higher resolution. Whether your monitor can work with such frequency and if the screen will be readable is different story.

Only allowed is 60 Hz. and also not so keen on staring at 30 Hz monitor 😛
Luckily, the motherboard has a USB-C port, which I can get a cable for USB-C -> HDMI / Display Hub
I'm assuming I can mix up the connection with HDMI and USB-C display. Is there any issues with that setup?

Monitor 1 -> HDMI cable -> HDMI port
Monitor 2 -> HDMI cable that converts to USB-C -> USB-C port
