pixellation problems with new computer - help!

Canon EF-S 18-135mm f/3.5-5.6 IS STM

I recently bought a computer -this -

HP Intel Pentium Dual Core T2080 1.73GHz Laptop (DV6403CL) - Refurbished - Web Only

- and it works great except that photos, images etc are incredibly heavily pixelated. The highest resolution the monitor is set, which it currently is, is 1280x800.

What do I do in order to smooth out pixels?!

The majority of 15.4 Inch Screens are 1280x800 in fact i havent seen one that isnt (of current market). My HP/Compaq is the same res and screen size. No Pixelation problems in fact the screen on my particular model display lower resolutions very smoothly. No clue what the problem is, if i could see a screen shot it migth show wether its the screen or somethings being rendered wrong. A picture of the screen would probably not work since most cameras moire and see alot more detail then we do.

EDITED: Anyways

SteveJ im pretty sure she is right about being at max res with that model.

Yeah i edited the part about being a laptop.

Id love to help her out but as i said not sure what the problem could be especially if everything else is normal. A Print Screen Screen shot and a snapshot of the screen with a camera might yeild slightly more information but maybe not....

1 - If its just in the web browser and your using vista or XP with Internet explorer 7, IE 7 has a new feature that allows you to zoom in on a web page in the right hand corner make sure the thing says 100% In fact i juste tested this theory and it does blow up images. If you accidently hit CTRL and scroll the Mouse wheel it also changes the zoom.

2 - If its all images well.... EEK! I dunno lol

Posterization??
Try going to display settings and make sure that 32-bit color depth is selected. If you're running in 16-bit mode, it will look posterized.

Are you talking about lines being jagged, or are you seeing pixelation even in areas of relatively constant color tone?

It's possible that whatever program you're using is opening the images in a size to fit the screen area, which may be a an odd scaling size that causes the image to look bad. Have you tried zooming to exactly 50% to see how it looks?

Hi all

First thanks very much for your advice, all of you! :-)

Briefly: the edges of everything in any kind of graphic and photo that comes up is 'chunky' in terms of pixellation. I already did max out the settings at 32bit colour depth and yep, 1280x800 is the max pixel. Comp is running Vista, so far as I know it has an up-to-date version of Explorer.

Another possibility (please don't laugh too much) I am using accelerated dial-up, not highspeed. Highspeed where I live means you need to pay to get a tower stuck on your roof for $300 Cdn and then $40 mth for crapola highspeed access. I mean I know it can't play online videos etc but that's fine, I'm working with still photos!

I don't use this comp for much else than Internet, to be honest; I am doing all my pp on my ol' trusty Mac G3.

I can try to get a pic to illustrate what screen looks like. Any other ideas or suggestions most welcome! Option of course is to drag it to Future Shop and have them 'splain it to me.

Turn off the acceleration on the dialup and see if that cures it. Accelerators do nothing but *strong* compression on graphics, and that's why photos look so terrible.

Ahh, that might help. Problem is I don't know how to turn acceleration down/off. I'll contact Juno and see if it can be done....

...hmm. Turned accelerators off and it really just slowed things down, maybe a tiny bit of improvement but still pixellation everywhere *sigh* Maybe it's the phone line, has some static on it.

I agree it smells like a Dial-up Accelerator...

Just curious, What is your Desktop DPI set to?

Right Click on an empty space on the desktop and choose Personalize
In the Task Pane (left) click on Adjust Font Size (DPI)

What size does it show that you are set to?

I have seen a couple new laptops shipped with Vista and Set to 120 DPI. 120 DPI will make your text/fonts larger and readable but on these to laptops I noticed it also degraded the Image Quality. If set to 120 try it 96 DPI and see if the IQ is better.

I agree that it sounds like your ISP is using some compression of graphics. Might be time for a call to their tech support.

Agreed. That sounds like the problem.

Did you make sure to check that Internet Explorer (7) was set to 100% and not zooming in causing the pictures to be enlarged and pixelated.

You could try installing Firefox, the problem could be with Internet Explorer.

I posted earlier 4th post i think. The right hand corner of internet explorer there is a little thing that shows a magnify glass and says % if its at 100% then well thats not it but if its higher then its blowing things up. There is another way to check it or if your on an older version it doesnt have it.

As to the firefox comment I use firefox daily but if its the zooming in IE it would be a problem in firefox also since it has the same feature....
