Secondly, over the HDMI cable, the notebook is unable to send video signal in 4K resolution to the 4K LG 65UJ634V TV directly (different HDMI Inputs already tested) or over the ONKYO TX-NR737 AV receiver. Installing the latest drivers in Update Driver inside Windows Device Manager Installing the drivers using the Lenovo Update tool (driver versions are mostly older than those installed using Intel Update tool) Uninstalling the Realtek High Definition Audio alongwith the above 2 drivers

Uninstalling the Intel Graphics and Audio drivers while in MSCONFIG -> Safe Mode (Minimal) -> Reboot again in Safe Mode (Minimal) -> installing drivers using Intel Driver win64_24.20. Installing drivers using Intel driver update tool, after uninstalling the Intel(R) HD Graphics 620 and Intel(R) Display Audio drivers in Device Manager (also checking the option to delete the drivers while uninstalling). Fresh installation of Win 10 with SSD format. I have tried everything suggested in the link: After inserting the HDMI cable, in Control Panel -> Sounds -> HDMI never appears, and sound always plays through notebook built-in speakers (Realtek High Definition Audio).

I have a new Notebook Lenovo V510-15IKB OS Win10 Pro, with built in HD Graphics 620, with which I am totally unsatisfied, because I have already invested multiple fruitless hours trying to solve the following problems.įirstly, I am unable to get any sound over the HDMI cable on LG 65UJ634V TV directly or over ONKYO TX-NR737 AV receiver, or on Samsung LE52B750 TV.
