Monitor Compatibility There was an issue with the on-board graphics and specific models of CRT monitors: it is believed to be caused by the current graphics driver setting a resolution that is not supported by the monitor. This causes the monitor to go blank and it is then necessary to unplug/re-plug the monitor to prompt a re-sync to a compatible resolution. A bug report will be made to AMD, hopefully it will be fixed in one of the next driver releases. As the issue only appears to happen with specific old CRT models it is not a major concern for current production systems. Until it is fixed a note will be added to our pricing page so resellers will be aware of the issue. Host RAID Cache Unlike previous versions, write-back caching is enabled by default on all newly created volumes. This has been found to cause issues with OS installation, Windows 7 in particular. It is recommended that you disable write back caching when using Host RAID for new Thunderbird systems- this will be done on all Compucon production systems. Performance does not suffer greatly when write-back caching is disabled.
