Hey guys,
So, yesterday I bought a Dell U2515H monitor (25", 2560x1440 resolution). Before that, I had an old Samsung 943NW (19", 1440x900) monitor. And had no issues with it for more than 7 years.
Now, the reason why I'm contacting you guys is that, with the same setup, but with the new monitor, this time connected via HDMI, I essentially can't boot into the OS. At least not at first.
Moreover, I can't boot into BIOS and I can't access the boot menu to, let's say, boot from a USB drive, or load another HDD/SDD. I can't do pretty much anything. After about 30 seconds, in which the monitor will throw an error about the resolution, the system automatically boots into Windows (where I have native resolution and everything ok).
You can see the error I'm talking about here.
So, after pulling my hair trying to figure out what is wrong with this and why does it work with my old monitor, but not with the new one, I thought I would try upgrading my BIOS. Which I did, successfully, from Windows, using your app. All fine there.
After that, I rebooted my computer and everything was ok (since all the settings have been reset to default)....until I went into BIOS and switched off CSM. After that, even with the newest BIOS, I got the exact same issue.
Please, note that all my operating systems are EFI enabled (the HDD is formatted to support it, so I'm sure there is no issue there). Also, the video card is UEFI enabled (with a UEFI GOP VBIOS), as well.
So, what I'm trying to say is that I don't need (and I don't want) CSM, at all. This creates an ugly/pixelated boot logo and everything just looks awful until I boot into the OS.
Unfortunately, I can't boot otherwise.
Did you guys try this BIOS on this motherboard, with CSM disabled, on higher resolution monitors? Did it work for you? I doubt I'm the only guy with a 2K display who wants a clean, fast, UEFI boot on his computer.
Anyway, I hope you guys have time to read everything I said above, and maybe you have an idea on how to fix this (maybe a beta BIOS?). I don't know.
System specifications below:
1. Motherboard: GA-B85-HD3 (rev 2.1)
2. BIOS version: F4 (same issue with F2)
3. Graphics card: MSi Nvidia GeForce GTX 650 OC, 2GB DDR5, monitor connected via HDMI. Previous monitor was connected via VGA (and had no issues with that, with the same BIOS settings).
4. CPU: Intel i5 4570 @3.2GHz
5. System Memory: Corsair 8GB DDR3 1600MHz, (2x4GB DIMMS in dual-channel)
6. 2HDDs and one boot SSD. No RAID, AHCI mode (I think..?). It's set to Auto.
7. OS: Windows 10 64-bit.
8. PSU: SuperFlower 80+ Gold 650W
Thank you very much for taking the time to go through this post, and I'm looking forward to your replies.
Best regards,
