Re: intermittent failure to detect both screens on fx4800 with recent drivers
At the time I wrote that comment, 195.36.31 had not yet been released. It does include improvement work for detection of DVI displays connected with passive DP-DVI dongles. Field reports from customers who had been affected by this and similar issues after upgrading to 195.36.31 have been positive so far.
If you are experiencing similar issues with 195.36.31 and Hosiden dongles, then display detection may be failing for other reasons. Please test with 195.36.31, and if you find you do have problems, start a new thread and include an nvidia-bug-report. Thanks.
