Hi! I have a Cyclone monitor and while I was running XF86 & Gentoo, everything was okay and fine. But one day, the monitor "fused" and had to be sent for repair.

While using an older "spare" monitor (Likom), I made the switch to X.org (but used the same XF86Config and the same S3 Savage Graphics Card driver). Everything was fine with the Likom.

Now, my Cyclone is back and when I tried it out in Windows, it looks perfect. But in Gentoo, the text & graphics is blur except for those that are right in the middle of the screen.

Since Cyclone has always used the same refresh rates as my Likom, I'm not sure what the problem is.

Has anyone got any suggestions on things I could adjust to try and get my text back to normal? I tried decreasing the gamma but it didn't improve the readability of the text.


Thanks,
Kristy

KristyX,

From your description, it sounds like your monitor is either still faulty or has not been properly set up internally after repair.

The fault sounds like an incorrect dynamic focus setting, which results in one area of the screen (normally the centre) being in much better focus then the rest.

Its not a Windows/Linux thing. A test pattern generator will show the problem without a PC being connected. If the fix is an adjustment, its quite simple to do. The hard part is not killing yourself when you do it.
Do not take your monitor apart - the exposed voltages are lethal.

That was my first thought too (and I was so annoyed at the thought of sending it back to the manufacturer and waiting another 4 weeks). But if it was the monitor, then when we hook it up to another machine it should be still blurred right?

That's why I think I'm missing something. Sending it back to the manufacturer isn't going to get me anywhere since the first thing they'll prolly do is to hook it up, take a look and see that it's already perfect :roll:

Any other ideas?

Thanks,
Kristy

Okay, it has to be X.org or something because I just noticed that when Gentoo is booting up, the display is picture-perfect.

Googling now..

Alright, I've given in and just switched my Cyclone monitor for my dad's monitor (he's using Windows and it's perfect for him).

I miss my monitor but at least I can look at the screen without getting a headache now :)

KristyX,

Heres a long shot but possible in view of the testing you have done.
The 'adequacy' of the dynamic focus will vary with the refresh rate you use.
What resoloution and refresh rate is Windows using?
Try that in X.

It may be that at the very highest refresh rates the dynamic focus is not up to the job.
