2D performance ATI compared to Matrox

Jo Vermeulen wrote:

Hi,

I recently upgraded my monitor to an iiyama 22 inch Diamnondtron
(HM204DT, Vision Master Pro 514). I'm really satisfied about it.

The only thing that bothers me is a fuzzy image at high resolutions at
high refresh rates (currently 1600 x 1200 @ 85 Hz). The image is
significantly more crisp at lower refresh rates or lower resolutions.

I think this is probably due to my Nvidia Geforce2 MX 400 graphics card.
I read a few posts and articles about blurry 2D quality with these cards.

I'm looking for an upgrade, and although 2D performance is much more
important to me, I wouldn't want to cut back on the 3D performance my
Geforce2 MX had (which isn't great compared to high-end 3D cards nowadays).

I just bought myself a Matrox Millenium P650, which has excellent 2D
image quality, and better 3D performance than my Geforce2MX.

Kind regards,

Apparantly it was not (only) my Geforce2 MX 400 card.

I had fuzzy quality at the right side of the display (this means for
example a fuzzy clock in the Windows taskbar).

I use the Matrox Millenium P650 now, which in combination with my
monitor gives a very crisp image in the middle and at the left side.
Unfortunately the right side is still fuzzy.

This is probably due to my Iiyama monitor. I will try to contact the
helpdesk on Monday, and explain my problem.

The ultimate test I did was take a screenshot of the right corner, save
it to a file, and view that image in the upper left corner, where it
displayed very crisp.

It's a pity

Kind regards,

Your montior have a bad focus adjustment.

I hope this problem can be fixed by getting a new monitor from the
dealer (same model, same brand ofcourse)?

The 'fuzzy' corner of the display will be either due to a fault in the
monitor itself, or maybe some external factor - magnetism ?
Try the simplest things first.
Make sure that there is nothing ganerating magnetic fields near to the
monitor - speakers, adapters/power supplies, force-feedback joystick,
external drive, etc. Just moving things around on the desk might make the
difference. At one time I had the power 'bricks' for various peripherals -
scanner, joystick, etc - plugged into a power strip on a shelf just below
the monitor. It didn't exactly 'help' the bottm of the display. If in doubt,
move it and see.

I unplugged the speakers and all near power 'bricks', with no change in
focus.

The monitor is plugged in together with the PC into a power strip,
located about a meter below the monitor (on the ground actually) :-)

But if the problem is magnetic/electrical interference, shouldn't I have
experienced the problem with my old monitor too?

Also, remember the unsharp picture occurs when I'm using high refresh
rates (85 Hz, 100 Hz, ...), and the picture is more or less OK starting
from 70 Hz to 60 Hz.

I also noted an unsharp picture, horizontally in the middle of the
screen, and vertically in the upper half of the screen:

Schematic:
_________
| x x|
| x|
|________x|


An x means loss of focus.

Kind regards,

Okay - you seem to have eliminated the easy ones - so it is probably time
for the monitor to visit a service engineer.

I contacted the Iiyama service, and they are going to deliver a
replacement monitor.
