- I will tell him to check the cable. He was using the VGA connector. He bought a new graphic adapted today and used the digital output; not so surprisingly, display is crisp now.
- He was using ClearType and I told him to remove it, but it did not fix it (I need to check that back with him, though); Anyway, I think not only the fonts but also any type of pixel was blurred.
Now, two points in your answer that got me puzzled:
1- His refresh rate was 60 Hz, but I told him to change to the maximum (75Hz - this did not change anything to his problem, BTW). On my monitor (17"), I feel that the display is much less tiring for my eyes in 75Hz than in 60Hz. In 60Hz, it’s like I can feel things are “flashing” very fast. Maybe just my imagination… but I have a fine result with 75Hz, so I am surprised by your answer. Why would they allow a higher refresh rate if this does not improve anything???
2- Your suggestion of 1280x960 is very good. I should have mentionned a detail earlier: the pixels are blurred “horizontaly only”, I mean horizontal lines display fine (except their extremities which are blured to the right and left), and vertical lines are blurred all the way. So it seems, (am I right?) that the vertical setting (1024) is equal to the native resolution of the screen, while the horizontal setting (1280) could be the problem. Though, as I said, we already tried different resolutions without success (maybe the ClearType was still on at that time, I am not sure anymore).
Oops, I just tried on mine, and while I am fine in 1280x1024, my screen cannot show anything neat in 1280x768, even after pressing the “Auto” button, and both horizontally and vertically (so my previous theory seems totally wrong).
It seems it will stay a mystery.
Since I don’t think my friend will spend more time in testing now that he spent the money for a new adapter, I guess you cannot help me more. Thanks a lot anyway . I hope this thread can be useful for someone who bumps into same problem… (good luck to them!)
