integrated graphics can't display 3rd monitor after i7 7700K upgrade

[HerrKaLeu]

I have the ASRock H170m Pro and have 3 monitors. Two 27" (2560x1400) on the HDMI adn the display port, and one 24 "(1980x1080) on teh DVI. thsi worked great with my i3 skylake.

I upgraded to an i7 7700K and only the two 27" displays work. teh graphics driver still recognizes the 3rd display, and it seems I can move windows there, but the monitor doesn't display anything. it works as main monitor if i unplug the large ones.

i had upgraded to latest bios, updated all graphics drivers etc. before i swapped processors and it still worked with the i3 after the upgrades.

I didn't see a BIOS setting that could be preventing seeing the 3rd monitor. I hope the i7 7700K can display 3 monitors (not sure why it couldn't, but you never know).

I assume I'm doing something wrong, but what? I really like 3 monitors because i work on the large ones and watch movies on the smaller one. I don't have a graphics card, and don't want one (no $, no heat etc.)
Edit: connecting one of the large displays to DVI and the small one to HDMI has the affect that large one doesn't work. so my DVI is the one that causes the problems.

Maybe you need a 270 board?

 

[HerrKaLeu]

Thanks for responding. I like to avoid to buy a new board. Especially if it is not certain this is the problem since the board itself worked with he Skylake i3. Although I will buy a new board anyway to "recycle" the i3 in a living room PC, I was more thinking of a cheap $45 board. My main rig has PCI-m.2 and the HDMI+display port and buying a new board with that would be more expensive. And if the CPU is limiting the 3rd monitor, it wouldn't help. I don't want to tear apart my PC more than I have to.

As I said I have updated the drivers and Bios from ASRock. I tried to de-install the Intel graphics driver entirely and then cleanly re-install to see if that helps. I noticed even after de-install and re-boot it still was there. I also noticed I can't play sound through the monitor speakers anymore (only through headphone jack). Not sure this is related, but points to driver issue.

I know the Z boards are the only ones that allow a third monitor (via the iGPU) when a dGPU is used for the first two monitors.

Before you waste any more time, I would double-check with ASRock that the setup you used to have is fully supported with the new CPU.

 

[HerrKaLeu]

cbn: what makes you think I need a Z-board to use 3 monitors? I know CPU is unlocked and could OC with the Z-board, but I see no reason of monitor not working in H-boards etc.
lopri: ASRock lists Kaby Lake as supported since 10/11/2016 BIOS version. Besides the monitor/sound issue it works perfectly in this board. for the last 2 days i had it running 24/7 converting videos at 100% load and using 68 W (per software Core-Temp)

Is there any information that Kaby Lake or specifically the K-versions don't support 3 monitors? I'm not sure why that would be, but you never know. I don't know how to attach pictures, or I would add a screenshot of the Intel Graphics control panel how it displays all 3 monitors.

I don't have a dedicated graphics card. All my monitors are hooked up to the motherboard. (I don't play games besides Settlers 4 which came out in 1998 or so....). 3 monitors (HDMI,displayport and DVI from motherboard ) was the setup that worked with my skylake i3, but not with the KabyLake i7 7700K.
Besides swapping the CPU I did not make any changes.
And no, i don't want to buy a graphics card with 3 ports (don't want the heat, the power consumption, and the $-waste as i don't need any real graphics performance)

 

[LTC8K6]

I think you need to explain your problem to Asrock and see what they say.

 

[LTC8K6]

If you are at BIOS P7.10, you could go back to BIOS P7.00 and see if that helps.

That page seems to say that 630 does not support 3 independent displays, but 530 does.

 

[LTC8K6]

I think that's just because 630 is newly released and not included in the docs yet. It must support it if 615/620 do.

 

[HerrKaLeu]

LTC8K6: yeah, my hope is this is a driver issue and they will update soon. From what i see ASRock is pretty good about updating drivers.
On the BIOS downgrade, this is my last resort, but i doubt this helps since i had upgraded to 7.1 with the i3 still in it and that worked with 3 monitors. So the 630 is more likely seems the cuplprit.
I meanwhile tested the 24" monitor on a different PC to exclude the possibility the DVI input broke, but it works. I noticed when I unplugged it, the Intel software recognized it only had 2 monitors left. After plugging it back in, the software showed the 3rd monitor.
I'm right now batch-converting movies (the reason I upgraded from i3 to i7) and don't want to shut-down and play with BIOS, drivers etc. Downgrading BIOS also can open another can of worms.
Edit: I sent a request to ASRock support and wait what they say.

 

[HerrKaLeu]

I contacted ASRock support and they actually responded quickly and we had some emails forth and back with some things to try out. One of their better advices was trying to install the intel beta driver . Well, didn't work at all. I even tried to manually install via Device manager, but there is no 630 in there (only 620 and others are supported). so that didn't help at all, and my best bet is to wait for Intel to come up with a new driver (the one above is of 12/2/2016, so before Kaby Lake release)

i have to say the person helping me was responsive replying to emails within some hours. but you have take the advice with some grain of salt. One advice was to revert BIOS to 2.2 (which does not support Kaby Lake!!!!), or re-install the OS. I think it was a bit shooting arrows in the dark. Maybe next time i plan to shut down my rig i try out BIOS 7.0 (which actually supports Kaby Lake), but really have no hope that will help.

I believe ASRock (and other motherboard OEM) are at eh mercy of Intel. I think it is weak they release a new CPU which cost billions to develop and tool, but don't have a driver?

Since I'm about to buy a new MB (to re-use my old i3) i was looking to see if one of the "200" boards maybe a possibility. but none of them seems to have 2 high resolution (2560x1400) connectors for my two 27" monitors (either dual HDMI or HDMI + displayport). Newegg lists some Asus boards (B250 etc.) with displayport, but that is actually wrong information since Asus doesn't list display ports for those.

so besides learning some tricks to install drivers i didn't achieve anything....

What OS are you running?

 

[HerrKaLeu]

W10 64.
Is there another?
How did you create this signature? I looked around creating one with my system data because it is tiresome to tell all hardware over when you need help.

 

[Shmee]

You go to your name, click signature, and edit it. It is just text I wrote in, nothing special.

 

[HerrKaLeu]

Shmee: I looked and looked what you meant with the signature since I can't see it. but Google told me the anandforum requires 25 posts before enabling the signature. This is my 25th post, so I'll see.

On topic: I downgraded my BIOS to 7.0 (from 7.1.) since that is the oldest BIOS that supports Kaby Lake. but that didn't help, still no 3rd monitor via igp. For the monitor sound (or lack thereof) i hooked up an old PC speaker for the time being. I'm not a firiend of that as it clutters up my desk, but works.
I installed an only Nvidia passive graphics card and hooked my small monitor up to that. After some trial i found the BIOS setting (need to set igp as primary) , installed the NVIDIA driver and now i can see my large monitors via igp, adn the small one via dgp. This isn't my favorite workaround since it adds heat and uses energy (even if only a little... this is just a $50 card with passive cooler). i really like the integrated graphics since they are more than sufficient for me and power-efficient (part of the CPU TDP) I updated my BIOS back to 7.1. (most recent)

once Intel or ASRock update their drivers i will try again. but right now this works and I'm 99% sure this is a driver issue of Intel not fully supporting the 630.

 

[mjdupuis]

This may not help in any way but isn't 630 graphics just a rename of 530? I could not find any technical difference from a brief internet search, and the wikipedia specs for Intel HD graphics showed similar clock speeds though Gflops data was missing for 630

 

[HerrKaLeu]

I downloaded the latest beta and the latest final of the driver and attempted to install it for a 530 (Device manager), but it wouldn't let me.
