------- Additional Comments From [EMAIL PROTECTED] 2003-03-27 09:19 ------- The problem with changing the default refresh rate has nothing to do with the video card. Older monitors, which are still in use, can be physically damaged by setting a rate higher than they are capable of. The ranges in XF86Config-4 are safe for most SVGA capable monitors. If your monitor is identified (through EDID) *and* has an entry in the database specifying what it is capable of you should get a range that works well. Unfortunately many monitors (Tatungs, in my experience) have incorrect info in the database that results in lower ranges than the manufacturer actually suggests, or the monitor is not in the database at all and gets the default. The fix is to make sure Mandrake has the specs for your monitor *from the manufacturer spec sheet* (as opposed to a 'best guess'). If the monitor isn't listed then Mandrake is quite correct in assuming worst-case and not allowing a range that could cause damage. Reading the EDID alone doesn't give enough information to make a safe judgement as to what ranges are safe. Especially on the multi-sync monitors that have discreet settings per mode amd cannot do in-between values (Older NEC monitors, for example). ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------- Reminder: ------- assigned_to: [EMAIL PROTECTED] status: UNCONFIRMED creation_date: description: Using mandrake-9.1rc1. XFdrake generates these default ranges for 1024x768: HorizSync 31.5- 57 VertRefresh 50-70 Obviously, which these ranges it is impossible to get any refresh rate above 70Hz. Since XFdrake does not allow one to choose the refresh rate, the default ranges should be larger, something like: HorizSync 30- 70 VertRefresh 50-90 Even 5+ year old cards like riva128 can do 85Hz at [EMAIL PROTECTED]
