Each of the PCI graphics cards in your 2002 PowerMac was using a long-established standard signal (VGA) to communicate with the monitors, so there was no problem.
If you build the graphics card into the monitor, you'd need a new (non-existant) standard to pipe graphics bitmaps and draw instructions between the PC and the monitor. (Unless X is up to the task... hahah)
OR, you could just extend PCI express over cables to the monitors. Which would work (you can already buy PCI express breakout boxes) but then you have much greater latency between the card and the system, etc etc etc.
- kalleboo 12y ago> OR, you could just extend PCI express over cables to the monitors We already have this http://en.wikipedia.org/wiki/Thunderbolt_(interface) http://en.wikipedia.org/wiki/Thunderbolt_(interface) Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal alongside a DC connection for electric power, transmitted over one cable. Up to six peripherals may be supported by one connector through various topologies. Not enough PCIe lanes to get enough performance for games but it should be fine for desktop applications.
- 7952 12y agoWhy exactly should latency be such an issue for graphics cards? If the graphics card only needs to refresh the screen every 15ms what difference would a few nano seconds make for the signal to travel down a wire? I'm guessing that reading to PCI express if already >100ns for large payloads.
