Alexandre,

can you test with another HDMI cable? Just because the HDMI cable works under Windows or Linux with a different GPU does not mean it will work under Linux with your HD Graphics 630. I am no expert, but there are all sorts of complications like HDMI clock frequency and colour depths. Linux with your 630 might be negotiating an HDMI connection that almost works but that your cable cannot reliably support. I would try another HDMI cable to eliminate it as an issue. Bad or marginal HDMI cables are a common problem.

FYI I am also using H110 with HD Graphics 630.

Kind regards,
