Hi,
I have a strange issue with my Vostro 3350 running Win7/64. One day after connecting my laptop to a projector it told me "no signal" on HDMI. While it was perfectly working just a day before.
HDMI does work with different cable (not the extender) as it should do.
I though that it is due to an HDMI extender I use (which worked perfectly well before) over 2 cat6 cables but the extender perfectly works with another set of equipment. Therefore, it is unlikely that this is due to the extender unless something specific can be mentioned.
The issue is deemed somewhere in the power HDMI emits or should emit.
Yes, VGA does work well.
Yes, I re-installed BIOS and both drivers for video cards
Yes, I tried to power on, auto selection of signal source, power settings in any order and selected all possible option by pressing [win]+P and Fn+F1
Would be grateful for any ideas
BR
