G-550 and video

[Brian Ellis]

I've just obtained 3 AOC (Envision) LM800 18" TFT monitors, thanks to a special offer. I'm quite impressed with their performance, with zero dead pixels (positive, negative or colour) on all of them.

I've hooked up two of them to a G-550 and notice that, if I play a DVD in PowerDVD, in Dual Head mode, the auxiliary one shows a distinctly redder colour balance, than the main screen, which does not follow the monitor, if I swap them, showing it's the signals coming from the card. Also, the auxiliary port gives a larger image on the screen (as if it's overscan hiding).

Are these normal?

[Frank Marshall]

I can't help you with this Brian but I was wondering what card you were using before you tried the LCDs with the G550, and if there were any problems using the other card?

I guess they are both on analogue connectors?

[Brian Ellis]

Yes they are both on analogue connectors. I had two different setups on the G-550 previously. The main one was a Hitachi 21" CRT monitor on 1024 x 768 and the secondary one was a Samtron 15" CRT monitor limited to 800 x 600, so comparisons could not be made. I had never tried swapping them round. This m/b has never used anything but the G-550 and the previous m/b had a Marvel G-200.

I am not sure about this, but can you use the colorific/whatever colour calibration tools independently on both displays to get them more matched?.

Have you loaded the LM800 monitor profiles?

[Brian Ellis]

It may be possible to put in different profiles, if one knew what they were.

The LM800 uses the standard Microsoft Windows drivers/profiles, There is nothing on the CD-ROM except the instruction manual in 586 or thereabouts languages.

I have managed to set them up so that the colours look more or less the same, using the monitor menu functions, but what I was really trying to find out was whether it was normal for the G-550 to give different colour rendering. I surmise that it is possible, because you need an adapter on the secondary outlet.
