hd4600 problem with external display

[GHorv1]

Hi Guys!

I am using an ASUS X550JX laptop (intel core i7 4720hq + hd4600) with an SAMSUNG T24D390 monitor TV in extended display mode with Windows 10. I have expereinced and issue using it. Sometimes the picture in external display has been dropped. The laptop is still in extended display mode but the screen turns black (voice disappear) in external display (on screen of laptop has no any problems), remote controll of TV does not work (TV does not react any controll). This problem occurs totally random (most of them after turning on laptop 5 minutes). If a plug off the hdmi cable then plug in it solve my problem and after that the computers can easily work without any problem even if i use it 10 hours constantly. Problem occurs using monitor with hdmi and using VGA cable also.

My configuration:

• ASUS X550JX with latest drivers.
• Intel HD 4600 with driver win64_15407.4279
• Windows 10 64 bit
• SAMSUNG T24D390 monitor TV with latest driver (analog and digital) and latest firmware

I have already used this monitor with an another older laptop with Windows 7 but I have not experienced any problem.

Thank you Guys!

I use external monitor in extended display mode. The secondary display (a TV monitor) suddenly switch off, voice disappear and the TV does not react any command from remote controll. This problem occurs sometimes but this problem appear very often in 5 minutes after i switch off my computer. Problem does not deppend on what am I doing with computer. The computer does not switch back to one display mode (still in extended display mode), even if i cannot "reach" secondary display

I have exacly the same problem with the same monitor on my desktop, not laptop. I have an Intel HD Graphics 2000. I also have this problem only with Windows 10. Please, help.

[Allan_J_Intel1]

Please bear in mind the Intel® HD Graphics 2000 does not have graphics driver support for Windows® 10.

I know, but Windows 10 already installed a beta version of this driver. This could be the cause? Eventually, it will appear stable version? There is no other solution?

[Allan_J_Intel1]

At this stage, Intel does not have plans to develop Windows® 10 for your graphics controller.
