Monitor? What monitor? How cabled?
There are three flavors of getting sync to the monitor;
composite, sync on green, and separate...
A display card with a SVGA connector on it will produce
one, two or all three flavors - either conncurrently or selectively
depending on card (manufacturerer, age, etc)...
Similar story with monitors...

If using an older HP (or other) high resolution monitor - it
most likely expects "sync on green" (or "separate" if it uses
BNC connectors)...
While your graphics card may have to be set (either manually
or by software) to produce other than "composite".

The short answer:
Your not out of luck yet - It could be something simple.

PS: the monitor that came with my 720 (5-BNC connectors)
will run with either "separate" or "sync on green" - it doesn't
recognize "composite" (the pc-world standard).
(Once you buy or build a suitable conversion cable)

PPS: SVGA connector:
1 - red
2 - green (sync on green here)
3 - blue
4 - sense 2
5 - self test (and TTL ground)
6 - red ground
7 - green ground
8 - blue ground
9 - key
10 - sync ground
11 - sense 0
12 - sense 1
13 - Hor. Sync (separate or composite)
14 - Vert. Sync
15 - sense 3
