Apple Event: May 7th at 7 am PT
I have an eMac that displays on a small portion of the screen rather than the entire screen. I’ve tried changing display settings in system preferences, reinstalling the software, and reseting the motherboard. The startup screen comes up full screen, but once it goes to the desktop it becomes small. I’m currently running Mac OS X 10.2 Jaguar.
null-OTHER, Mac OS X (10.2.x)
Early eMacs had a known issue that caused the screen to distort or collapse. It was caused by a bad IVAD cable. I am thinking that's what you've encountered. Units most often affected were from time of introduction (April 2002) though fall 2002. Most of the affected units received new cables and later first models never showed symptoms. Interesting discussion here:

We may be of more help is you can hlep us identify your exact sub-model as, of the four families of eMacs, two had known serious hardware issues. First see this Apple support article:

The lookup table has lost its borders (at least in Safari 11) so this copied image may be easier to read:
Once we know the sub-model we can beter advise a troubleshoting scheme.
If we need to recommend parts, that is easier if you let us know roughly in what part of the world you reside. It does you little good if we recommend a vendor who does not ship to your region.

Could be the PRAM NVAM may be a direction to look. Because these settings
can also be affected if the clock battery (..1/2 AA 3.6V Lithium battery on LB..)
no longer supplies minimal power to keep the settings memory alive. That may
be part of a solution; to get a new battery and also reset PRAM/NVRAM.
An iFixit guide may be helpful to access the panel to replace this battery.
