Intel Graphics refresh rate drop and are inconsistent after sleep or hibernate

LEB — Mon, 05 May 2014 13:31:56 GMT

Systems with Intel HD graphics have inconsistent monitor refresh rates, lower refresh rates and poorer graphics performance after resuming from a 'sleep' or 'hibernate'.

To reproduce for systems with Intel HD graphics:

Make sure the monitor is set to its highest refresh rate (e.g. on Dell U2711 monitor, choose 60 Hz rather than 59 Hz; or on a Dell Latitude E6320 laptop, choose a refresh rate of 60 Hz, not 40 Hz).
With a user logged in, either close laptop lid, or put the system into 'Sleep' or 'Hibernate'
Wake the system up again and log in
Check the Monitor refresh rate under the Intel "Graphics Properties" - the refresh rate has dropped from the higher setting to the lower setting and is now either 59 Hz or 40 Hz in the examples above.
Check the Monitor refresh rate under Windows Control panel -> Screen Resolution -> Advanced Settings -> Monitor -> Screen Refresh rate. Here the original higher refresh rates are still being reported. I.e. the refresh rates being reported by Windows vs. that reported by the Intel driver GUI are inconsistent after resume. See attached screen-shot.
Use windows desktop - the system is now slightly but noticeably more sluggish/lower graphics performance after resume.
In addition, after the screen goes in standby, the screen 'forgets' brightness and contrast settings set in the Intel Graphics Properties after waking up again (screen returns to brightness/contrast settings it had prior to setting them in the Intel Graphics Properties).

This issue occurs both for the built-in laptop monitor as well as an externally attached secondary monitor (connected over DisplayPort).

The issue also occurs on the monitor attached to a Desktop PC running Intel HD graphics.

Monitors on which the issue has been reproduced:

Dell Latitude E6320 built in laptop screen
Dell U2408WFP monitor (Display Port)
Dell U2711 (Display Port)

This issue occurs both for 2nd and 3rd generation Core i7 HD graphics, from a Dell laptop, as well as from PC with Intel Motherboard (Z77).

All systems running Win 7 Pro, sp1, x64 with all updates, latest drivers and BIOS.

Thanks

Hi EBL,

I understand you are having an issue with the resolutions and refresh rates.

All the information you have provided is good and I will try to replicate it from my side but I would like to know some more information about the system you have.

Can you please provide the graphics report and the dxdiag report? If possible attach it here.

Hi Kevin

I have attached the output from the Intel Graphics Information Center, as well as the output of dxdiag.

The Graphics Information center does not allow the saving of the monitor's info - I have taken a screenshot of that.

Please let me know if you need anything else.

Thanks for all this information. The driver you have installed seems to be the OEM driver so can you try our driver?

Here is it:

We have not received reports from other customers about this issue. If you try the driver and issue persist, I recommend you contacting Dell for them to provide information or replace the unit if necessary.

1. For the Dell laptop - unfortunately the problem exists both with the OEM and the Intel drivers

2. For the Intel Desktop system, the same issue occurs (Intel DZ77BH-55K board). This is therefore not a Dell related problem, since an Intel system has the same issue, with the latest drivers.

I presume no one has reported it yet since they haven't noticed, or are using 3rd party / Nvidia / AMD graphics.

I would appreciate it if you could look into this problem.

I will test this and I will be back as soon as possible. I will keep you posted.

Re: Intel Graphics refresh rate drop and are inconsistent after sleep or hibernate

Kevin_M_Intel — Wed, 14 May 2014 18:33:32 GMT

Just a question, did you test the DZ77BH-55K motherboard with 2nd or 3rd generation? And if possible what model? Also what Operating System did you try?

Re: Intel Graphics refresh rate drop and are inconsistent after sleep or hibernate

LEB — Thu, 15 May 2014 08:04:19 GMT

The DZ77BH-55K motherboard is with the 3rd gen i7-3770 (not 3770K). OS: Win 7 SP1, 64 bit, with all updates, latest drivers and BIOS.

Hello EBL,

Sorry for the delay.

I have tested this motherboard with the processor in mentioned and I was not able to replicate the issue. I tried different monitors including a TV but the issue did not come up.

I would like you to attach the Intel® motherboard dxdiag report here so I can check it because so far and based on the lab it seems that the problem may be related to the monitors and not the graphics controller.

Hi Kevin

The dxdag report for the intel desktop system is attached below. I have also attached a screenshot of the different refresh rates for the desktop system when resuming from sleep.

Note that all these monitors are connected via Display Port (not VGA or HDMI).

dxdiag - Intel Motherboard

Thanks for the information. I will pass all this information to development team for further investigation. I will keep you posted.

Thanks

One point: I note that after sleep (or even simple standby of monitor), all monitor settings are reset/forgotten, not only the refresh rate, but also any other settings such as brightness/contrast set via the Intel graphics control panel, revert back to what they were before they were set.

Thanks, We are still working and I am checking for updates.

Sorry for the delay on this. We are working but I would like you to try with latest BIOS and graphics driver for the system. I will provide updates soon.

LEB — Fri, 20 Jun 2014 07:51:41 GMT

Thanks, the BIOS and graphics driver version currently installed are the most recent versions available via Intel's driver download page; or are there more recent versions which you would like me to test?

Regards

Hi,

I also had the refresh rate issue on my Sony Vaio SVS13A laptop, but it seems to be fixed with the recent drivers for me.

BUT I have a similar issue after suspend: My laptop has a built-in brightness sensor that can control screen brightness. After resume from sleep, the automatic brightness control does not work properly, because the driver does not involve my brightness setting anymore. This means: Instead of regulating screen brightness around the value set by me, it drops back to some fixed value every time I set it to another value. This is really annoying since I have to restart to fix this. I'm running Windows 8.1 Pro on Core i5 3210M with Intel driver 10.18.10.3621. I didn't have this issue on driver version 9.17.10.2817.

Kind regards
