I have problem on my Lenovo Y50-70 with i7 4710HQ (but my friend with i5 4210H too) on W7 PRO x64bit when mirror external monitor with screen tearing (splitting screen in half) . We tried all intel drivers (includes Lenovo intel video driver) , but the problem is still here.
Tearing is always only one monitor, when I set external monitor on first position, I have tearing on my laptop screen. When I switched them, I have tearing on external monitor.
I don't know if this problem is tearing, but screen split in half and this split slowly moving up or down.
I tried different resolutions too. Both screens we have on 1080 60p Hz .
Extending screen on external monitor is OK.
Thank you in advance.
I have clean W7 installation from Microsoft website.
I mirroring laptop display to LG TV (47LM640S-ZA)
Today I will try another TV/Monitor , so then I will write you results.
Yes, laptop and TV both connected via HDMI
TXT file I upload tomorrow.
Thank you for quick reply, the problem is only when I clone/mirroring displays. When I extending them, it's everything OK.
Yes, sorry for my long responses, but I don't have much time to answering (too much work) . Today I write to Lenovo forum with this problem (Lenovo create new Czech and Slovak community, so for me is much more easier now to communicate with Lenovo) , but as I said, this problem I have on two laptops on any external monitor/TV . Only mirroring/cloning screens. And OK today I install Intel utility tool too on my second laptop and send you info after scan.
There are some differences between W7 and W10 drivers well? Maybe in W10 this problem is solved? I can't try W10 at the moment on these Y50-70 laptops. So the only hope is Lenovo forum at the moment?
