Hi Milan,

Raspberry Pi only has digital HDMI signals. They are compatible with a DVI-D monitor, but not VGA. You need a converter box to convert the digital signals to VGA analog signals. There's a lot of information at the RasPi Hardware Wiki here and here.

DVI as produced by most PC video cards is DVI-I, which has pins for bit-serial digital signals (DVI-D) and other pins for VGA analog (DVI-A). Since a PC video card has both, you just need a cable to attach it to a DVI-D monitor or a VGA monitor. But this doesn't work with RasPi, since it only has digital on the HDMI connector.

There used to be a HDMI to VGA adapter showing in the Pi Accessories.

I can't seem to find it now...

I knew I saw one.
The part number should be the same at most e14 outlets, and is listed at NZ $32.48 inc tax.

Mark, thank very much :-)

Today I was visiting my brother in Belgrade (Serbia) and he gave me his old monitor
which of course had only VGA but also some mysterious port.
Later I found out that it is a BNC.
So now I have to buy RCA-to-BNC adapter (very very cheap) to connect my Pi with "video" cable...
I know that screen quality is poor but I'll try that for now.

Mark, I found your adapter at Farnell and I will try to buy it.
I really appreciate your help.
tnx again

Milan
Glad I could find it and it might help.

For other readers, there are plenty of LCD monitors that go faulty, and tend to head to the recycling.
For 99% of them its likely to be the capacitors, which have died, and are easily replaced.

If you have the chance to repurpose something, then for less than NZ$20, a soldering iron, and maybe some solder wick/desoldering you can fix them.

Choose 105deg caps and check the ESR rating (low ESR = good high frequency performance) , size and of course voltage.
There are videos of repairs (useful to get them apart) if you still need convincing, but you'll be surprised how easy it is.
