5554898 Forced 1080i in some DX11 games is causing screen flicker.

[AKost6]

Hey Folks,

When loading DX11 games in full-screen at 1920x1080, the Intel HD Graphics Control Panel sometimes forcefully changes the video output to 60i Hz from 60p Hz. As a result, it causes horrible screen flicker. Changing the game to run in windowed mode returns it to 60p Hz and removes the flicker, as does changing the resolution from 1920x1080 to something else. This is only noticeable on the SECOND screen, which is a plug 'n play standard 1080p monitor.

PC Specification:

Graphics: GTX 880m (running driver 337.50 beta - no alternative version available yet) & Intel HD 4600 integrated (running latest drivers).

CPU: Intel i7 4910MQ 2.90 GHz.

RAM: 16GB DDR3.

2nd Monitor: 24" 1080p LED screen operating at 60Hz connected via DisplayPort -> HDMI (though HDMI -> HDMI makes no difference).

OS: Windows 7 Pro SP1.

Why would the Intel drivers be automatically forcing my resolution to 1080 interlaced when the monitor can (and does) support 1080 progressive in every other context?

Thanks.

Hi Costlyy, I have some questions about your issue:

• May I ask how did you determine that Intel® HD Graphics is causing this issue and it is not part of the Nvidia* graphics driver?
• Does your system have a switch to manually select only one of the two graphics adapters?

You may want to update to the latest BIOS provided by the system manufacturer.

Please provide the game titles, system model (or msinfo32) and Intel® HD Graphics driver report.

i have the same problem,

Asus G750jz, connected via HDMI to 22 Asus monitor, you can see the flicker in Full screen on games like Civ V and Company of heroes, please advice, thanks!

[Jose_H_Intel1]

morismichael, would you please provide the same two reports suggested above?

[mmich38]

Sure, once ill get home, thanks!

Hi Joe,

I determine that this is caused by the Intel drivers as opposed to the NVIDIA because the NVIDIA drivers do not control screen resolution / refresh and do not even have the options available. It is only Windows or Intel that can be causing this.

The preferred graphics processor is set globally as "High performance NVIDIA GPU" in the NVIDIA control panel.

As morismichael said, this only seem to happen in certain DX11 games such as CIV5, ArmA 3, Tomb Raider 2013, etc.

Thanks,

Al.

let me know if you need anything else, and thanks for your help!

It seems that other common factors you both have are Intel® HD Graphics 4600 and NVidia* GTX 880m. At this moment the graphic driver versions you are using for each graphic adapter are different.

Usually the computer manufacturers design their systems to use NVidia* graphics for performance and gaming, it is because of this that I find this issue mostly related to NVidia* graphics and I highly encourage you to check with them or with the system manufacturer.

Still, you may also try updating to the https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3720&DwnldID=23714 latest Intel® HD Graphics stable version (morismichael) or the https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3720&DwnldID=23858 beta version, latest BIOS, testing with Vertical sync in game and NVidia* options (Use applications settings is the default option in Intel® HD Graphics control panel) or a different monitor.

I also wanted to ask if the game is only running on the second screen or both. Is the display mode set to clone, extended, or collage?

[AKost6]

Hi Joe,

I have not yet found an acceptable solution, nor has one been offered elsewhere, and this issue is starting to get irritating.

My displays are running in extended, it is only the second monitor (marked as main) that suffers, and vsync makes no difference.

Is there any way that this support ticket can be raised to something more urgent?

Thanks,

Al.

[mmich38]

Thanks for the replay, in my case the games are running only on the 2nd screen

[mmich38]

Costlyy

did you manage to find any solution yet?

[AKost6]

morismichael, not yet. I've posted back to Joe with the latest.

[mmich38]

i decided to try HDMI to DVI cable and all works fine now, i still wish that the HDMI to HDMI cable will work as well

[Jose_H_Intel1]

Let me investigate further. In the meantime, is there any difference if you right click on the game's executable file, select the option "Run with Graphics Processor" so you can try with either graphics controller?

[AKost6]

Running with either graphics processor suffers the flicker from forced 1080i.

It is the Intel hardware and drivers that control the second screen, the fault lies there somewhere.

Hi Costlyy

The latest nvidia driver for your video card is this: http://www.geforce.com/drivers/results/102995 Drivers | GeForce

[Jose_H_Intel1]

The issue has been reported. I will update the thread as soon as news or updates become available.

[MMara4]

I'm experiencing the same issue and came across this thread. I have a Clevo/Sager P157SM-A with Intel HD 4600 (latest drivers installed) and NVIDIA GTX870M. As I understand it (and it appears to be the case due to lack of options in the NVIDIA control panel), that the Intel GPU is managing the HDMI/DisplayPort connections. I have a DELL U2314H monitor and have tried via HDMI and DisplayPort (directly), in both cases certain games (e.g. Arma 3) will switch to 1080i mode in fullscreen mode (and not 1080P). I have played around with settings in the Intel control panel (59p Hz, 60p Hz) without success.

The work-around currently for me is to clone the laptop display and external monitor (so both are active). In this case the external display correctly switches to 1080p mode when entering full-screen.

Please provide an update on this issue!

Thanks.

I have the same problem using only the integrated graphics (HD Graphics 4600).

Starting Civilization V with DX11 in fullscreen makes my display (DELL U2414H) to switch from 1920x1080 to 1080i and showing screen flicker.

If I run the game in windowed mode it shows no flicker, because it stays in the same 1920x1080 (p) mode like the desktop.

Starting Civilization V with DX9 the fullscreen mode works without any flicker, it then runs in 1920x1080 (p).

The display is connected via DisplayPort and shows the same behavior using HDMI or DVI to HDMI.

I have the same issue. I have Intel i3 with HD 4600 integrated graphics as the only video card, and a Samsung 50" TV. As other people described - DX 9 works normally, DX 11 forces 1080i when running full screen.

I also discovered this problem while playing civ v on dx11. However, the weird thing is in one of the first times this happened, it reverted back to 1080p. I have no idea why. Since then it has continuously been forced into 1080i and flickered. I have found this to be the case with multiple other games on steam as well, but only when running on my second monitor on full screen.

Some basic system info:

comp- (i7 4710mq 2.50ghz, intel hd 4600, nvidia gtx 765m 2gb (both running latest drivers as of 7/24), windows 8.1 64 bit, 16 gb ram)

monitor - (asus VS247H-P 24in, 1080p 60hz led connected via hdmi)
