Hello Experts,
I recently acquired an XPS L521x, an upgrade from my old 15z. I mostly use my laptop connected to a larger monitor for work and my TV at home through HDMI. I have tried to get the HDMI to work on this laptop but to no avail. When I connect the cable to the laptop, there's no indication of the TV/monitor being detected. Switching the display output does not yield any results either. However, my 15z works perfectly OK on both displays. I have tried all the following:
1. updated the intel hd 4000 drivers to the latest version
2. updated system bios
3. downgraded to windows 7
4. used multiple hdmi cables (had to buy a couple of new ones)
5. tried on friend's monitor
6. downgraded drivers to older versions
..and it still doesn't work or show indication of external display recognition. Any assistance will be greatly appreciated.
Thanks!
