(Gigabyte) UEFI BIOS Screen Resolution Issue?

post #1 of 20
Thread Starter 
Question/Issue... I’ve got a Gigabyte GA-Z170X-Gaming GT motherboard consisting of….

  • Intel i7-6700K
  • Corsair H115i AIO CPU Cooler
  • 32gig Corsair Dominator Platinum RAM (3333)
  • Sapphire Tri-X R9 Fury (Non-OC)
  • Samsung 950 Pro NVME, m.2 SSD drive (OS)
  • Samsung 850 Pro (data/photo work)
  • WD 2TB drive (Games, data, backup)
  • SoundBlaster ZXR Soundcard
  • LG-Blu-Ray Drive
  • EVGA Supernova 1000 G2 (1000-watt) PS
  • Cooler Master HAF-X case
  • Windows 10 x64 Pro
  • NEC MultiSync PA242 (24”) monitor


Anyway here’s the issue… with my current GPU (Sapphire R9 Fury) installed on the Z170X board, when in the UEFI BIOS, the default screen resolution reduces to 1024 x 760, which is far from my native resolution of 1920 x 1200. However, when the system boots into Windows, the resolution automatically adjusts to the screen’s native res. So no biggie there, all is good.

However, researching why this weird behavior occurs on this board when it didn’t happen with my Z87 (Gigabyte G1 Sniper 5) is still a mystery. That said, I did discover an odd repeatable issue… If I use an HDMI cable, the native resolution of the screen (1920 x 1200) does work in the UEFI BIOS; with a DisplayPort cable, the native resolution on goes to 1024 x 760 (in the UEFI BIOS).

Oddly enough, this same GPU (no mods, or BIOS updates) used on my Z87 board allows full native resolution in UEFI with no issues.

So, my question… can anyone else confirm this? Differing screen resolutions in the UEFI BIOS depending on cable used - DisplayPort vs HDMI.

Thanks.

I've always wondered how to change the resolution within the bios screen. 1920x1080 bios would be amazing... I'd feel like its actually from 2016...rolleyes.gif

And....????

Did this ever get figured out? I'm shocked: a 2016 Z170 board with 1024 x 760 resolution?!

This was a problem noted on a September 2015 review. Tell me this was fixed. Have you all updated your BIOS? Seems like the early builds for the Gaming 7 shouldn't even shipped out.

No. I've not solved it yet as I think it's a function of the way the UEFI BIOS is acting with my card. As I stated, if I use an HDMI cable the issue is gone, where using the DisplayPort cable gives me the weird issue. It's no biggie though as it only affects the UEFI resolution, and nothing else. I'll wait and see what a new BIOS brings if Gigabyte decides to issue one.

Thanks

BTW instead of having me read through that entire review, can you point to the page or section where it points to my issue? Thanks

Oh, and I have the Gaming GT, NOT the Gaming 7.

Sure, it could just be the card. But, that would be peculiar. DisplayPort, in my thought process, is the default interface for monitors: it should work on that one and maybe HDMI is doing something funky.

Err, it's a whole page: http://techreport.com/review/29072/gigabyte-z170x-gaming-7-motherboard-reviewed/3

They likely didn't test HDMI and just used DP; thus, they only ever got 1024x768 out.

Sure, no worries. I think the Gaming GT and Gaming 7 are almost identical, actually, save a few parts.

That may be now, but for the most part it was DVI, HDMI, now DisplayPort. Going back further, VGA.

Anyway if you actually read my whole post, you'd see this issue didn't happen with the same card, monitor, and cable under my Z87 board. However, that UEFI BIOS is different from the basic UEFI BIOS of the G7/GT. Here's a YouTube of the G1 Sniper 5 BIOS, which is far more advanced than either the GT or G7. And I'm betting similar to the one used on the flagship GA-Z170X Gaming G1.

At any rate that's why I say BIOS issue. Could be wrong, but...

Edit... yeah, now I see where the article mentions my observation (issue). I'll bet that if they used an HDMI cable, the BIOS would res out to the monitor's proper resolution! Weird.

Thanks.

...HDMI was never the standard for monitors. Whoever told you that was quite confused between a monitor and a TV. Yes, now. Were we talking about the past? We have a long history to go through if you want to talk about the past, tongue.gif

Obviously. That...that is the entire point of my question. The motherboard shouldn't have this issue; the cable shouldn't matter. It is a BIOS issue.

Sigh. Did you read the link I've posted twice now? That video shows the Smart Tweak UI; I'm sure you saw it on your Z87 motherboard as my Z87X-UD5H has that interface now. And, the Gaming G1 is no different...again, if you read the link I posted, it will show you that this is on all Z170 motherboards by Gigabyte...from the $150 to the $400 ones, at least that was true as of last year when the boards released.
Quote:
Gigabyte tells us that they're still working on the Startup Guide and Smart Tweak interfaces for the board. Right now, Classic Mode is the only game in town.

Never mind. I think this discussion isn't going anywhere. If Gigabyte still hasn't added the Smart Tweak interface to the Z170 motherboards by now, nearly 10 months later, they likely never will. Looks like Classic is the only option @ 1024x768 (unless you're comfortable with the compromises involved with HDMI, namely lacking 120Hz support).

Hmm...it's not a major issue (how often are we going into the UEFI?), but it's a lack of polish from Gigabyte and at least a iffy promise to one reviewer. "Still working..." as in, we'll probably ship Z270 before we backport Smart Tweak to Z170 boards.

So the only way ever to connect a monitor to a GPU was through a DisplayPort? Old standards didn't exist?

I don't need 120Hz support because my monitor doesn't support it. NO... my NEC PA242W isn't a cheap old monitor. It just isn't a 4K monitor. And I also said I would live with the issue as it doesn't affect anything other than being a nuisance for not being able to run full res in the UEFI BIOS. I was just curious if others saw my issue. They did as you pointed out in the article. Thanks.

Smart Tweak UI on the Gigabyte GA-Z170X-Gaming G1....



AnandTech Review, BIOS section: GIGABYTE Z170X-Gaming G1 BIOS. Seems like the lower (as in beneath the G1) end boards aren't getting it.

Oh BTW, It's cool to disagree and debate, I'm cool with that, but tis no mere rookie here; I've been around PC's a minute or two smile.gif

Err, no, of course you can use HDMI, VGA, etc. But....I did say the standard, which is DP.

Sure, then. HDMI is great for 60Hz. I didn't say you had an old monitor or 4K. My monitor is a 1080p TN monitor, actually, haha.

No worries; I'm in the market for the cheaper version of this motherboard, the Gaming 7, so I'm trying to get as accurate picture as possible.

EDIT:

Hm, the review mentioned in my link shows on November 25th, the G1 Gaming had just Classic. Then, on December 1st, the G1 Gaming had Smart Tweak as well. Very peculiar why that wasn't made aware to the folks at TechReport; editing a review 6 days later on a major change is not unusual...

Err, I didn't mean to assume you were a rookie, but I just thought you hadn't read the links I had sent and assumed that I was just posting without reading your issue, which I did read, for whatever it's worth.
