Poor Quality Screen

Logla · Sep 8, 2003, 08:15 PM

I just got myself a new monitor last weekend as my old HP gave up on me with a bang.

This new one is a (fairly) cheap 19" FST made by GNR and branded as a Diffusion.

I got it home, connected and powered up and was quite pleased with the colour reproduction etc and then chose to ramp up the resolution. At this point I was gutted. at 1280x1024 the display is blurred in the centre of the screen and it has faint wavy lines across the screen. they are only just visible but I do notice them. It looks almost like magnetic interference but I moved all my speakers etc and this made no difference.

I can adjust the focus but all this does is sharpen up the centre and then blurs the top of the screen. Also, the edges of the screen are sharp but the text seems to have a moire effect to it the further out to the outside of the screen you get.

At 1600x1200 the wavy lines dissapear but the screen becomes very blurred and the text is too small to read at this blurryness.

A guy at work suggested that this may be a problem with the shadow mask so I'm probably going to make a warranty claim (can't take it back to the shop as they have a poor returns policy to say the least) as it has a 3 year on site.

What I'm bothered about though is if they send a replacement and its exactly the same.
Anyone else got one of these and/or had similar problems.

not sure.

are you using plug & play drivers?if so can you get drivers for your monitor.

could be refresh rate is that set correct for the rez your using.

might be a small possibility unless you have allready tried what i have said.

Tried all that mate. Used the proper drivers and I've managed to get rid of the wavy lines using the v-moire. Cannot get the screen to focus properly though. this is really annoying cos its making me feel like I've got something stuck in my eyes. Horrible

Hmph, that's why I splurged the money and invested in a nice 19" Sony CRT. The best computer can be da shits if the image quality really blows. And it can cause eyestrain too.

What is the dot Pitch on it? (seems to be the exact symptons i've seen on 0.30+ DPI monitors.... erg, you get above 1024 and things get ugly fast)

Although, the only benifit you usually get from a dot pitch that's larger... is high Refresh rates....

This one has 0.26 Only now I can't get the damn thing above 60Hz. windows reports 85Hz, which it supports but the monitor will not switch properly. I can go lower than 60Hz - 47Hz interlaced for example. Time to report a warranty fault me thinks.

Ah great! I spend all evening performing a rebuild on my windows partition thinking the refresh rate prob was something to do with software and its not. Tried another older monitor and that gets to 85Hz no probs.

The worst thing is I can't get a day off work for 2 months in order to arange the swapout. How sick am I?

,.....erg.....that's the worse...... Best bet is to take it back.... or something.. (9 thought 58hz was hard on the eyes.....)
