Sorry, I really really can't tell from your photo. Is that an old Apple display, or maybe a Formac monitor? Long ago (ok....only 5 years ago, but I'm young), Formac was the bomb, and people recommended their monitors over Apple (sometimes) due to their price and performance. Nowadays, people tend to recommend the Dell 20" and 30" because they do have the LG-Philips S-IPS LCD panels, but 5 years ago, the name "Formac" meant something around here. I have no idea how they have done so poorly for themselves. It seemed like such a quick death.
Anyway, could it be a Formac monitor, possibly an older one? 😕
