Dual Monitors & Custom Drivers

Russinating · 24 Apr 2007 at 14:07

Got another Hanns-G 19" (HW191D) today, and having trouble matching the colours. The reasoning is the custom drivers than come on the CD. I used them on my first monitor, and now can't seem to find a way of applying them to the second. I've used the custom drivers for every monitor in device manager so they're all identical but still nothing. On the monitors OSD's the following info displays:

First Monitor:
H: 55.7Khz V: 59.7Hz - 1440x900

Second:
H: 70.9Khz V: 75.3Hz - 1440x900 - User Mode

How do I change these manually so I can get them the same? :confused:

Firstly I'd recommend using 60Hz on both screens, 75Hz gives no tangible benefit for most TFTs and can actually detract.

Secondly, I'd lose the monitor drivers altogether. Do you happen to be on an nVidia-based graphics card? If so, you can set separate colour adjustments in the drivers by highlighting the screen you wish to tweak in the Display Properties->Settings window before clicking advanced. ATi may well be similar, but I'm not up-to-date on their drivers.

Do these screens not allow much adjustment in the OSD?

ATi is similar, Avivo Colour adjustments are a submenu under each digital panel.

Just gotta say, 75hz makes a difference on my TFT, my Hyundai N91W flickered to my eyes on webpages with those backgrounds of a one pixel line of colour followed by another in alternate streaks, up it t 75hz and those flickers are gone...

Thanks guys, set both to 60hz and found the advanced options to get them both at H:70.9Khz and V:75.3Hz

why does it flicker at all? I thought with TFTs if a pixel stayed blue it would stay blue, not go blue off blue off blue off like a CRT "pixel" does?

The backlight can cause flicker. Fluorescent lights can give noticable mains cycling.

if you can notice that at 60hz, wouldn't you get a headache anytime you went in a room with fluorescent lighting?

Some people are susceptible to migraines under fluorescent lighting, most aren't to any large extent. I'm no sparky, but there may be clever ways of upping the effective cycling frequency on a CCFL.
