I am having this strange issue all of my x series laptops (x240, x250 and x260). We are running Win7 x86 and got few Samsung and LG TVs to be used as external screens in meeting rooms. Laptops get connected to DV adapter via HDMI>DV adapter.
Since last couple of weeks laptops are not able to connect to 2 TVs (1 x LG and 1 x Samsung) via DV port. As per our AV vendor it's an issue with the laptops.
This is what I have tested so far:
Changed refreshed rate
Updated Intel Graphics driver
Changed HDMI cable
Changed DV adapter
Since X260 has a full HDMI port I connected directly thru it and it works fine
Tried with HP and Dell laptops - connect fine with HDMI port
None of the latest Windows updates deployed on our laptops relate to Lenovo
Anything else I can try?
