Hey everyone,
I bought this laptop brand new a couple months ago.
When i'm looking at pics they come up blurry and aren't as crisp as they were when the laptop was new.
What do you think the problem could be?
Thanks

Full Version: Pics Are Showing Up Blurry
Looks to me like the screen is not running in its native resolution?
Find out what your panels native resolution is, and change your screens resolution to match. Or at least verify that it is already running it.
Alternatively, just try different resolutions until you find what it is. A square monitor is typically 1280x1024, 1152 x 864, 1024x768. Widescreen will be more like 1680x1050, 1280x960, 1280x720.... or something.

I thought this too, but usually when you run it at the wrong resolution everything looks blurry, but in the pictures she provided everything else was fine.
Its got me baffled, if you open a picture from your computer is it blurry?
The text looks a bit off to me too though? Unless its just the JPEG artificing... The bluriness wont show up on text as much as on images as its just straight lines.
Can the OP put up a screenshot saved as BMP or PNG?

Right click the MSN Accelerator icon in your system tray and set the level to “none”.
"Acceleration" determines how pixelated and compressed the images become.

I have a new Dell notebook with wide screen display at work (dell latitude d810 running on ati radeon mobility X600). This notebook
was shipped with default 120 dpi font size to make the fonts more readable (wide screen display is really cool, but now and than you want to read something on it as well ;-).
Anyway, if you use the default dell settings you may experience the problem with blurry images in Internet Explorer. This effect is due to the automatic scaling in IE6 and above. IE tries to resize the images so that everything looks the same as when everything is at smaller dpi, but does a terrible job at it, resulting in blurry and unreadable images.
Change the following registry setting from 1 to 0 in order to disable this "feature":
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\UseHR

Click "Tools" in the top menu bar of Internet Explorer. Select "Internet Options" from the drop-down menu. Click the "Advanced" tab and scroll down to Multimedia. Check the box next to "Smart Image Dithering." This will help to ensure that images are loaded properly.

With IE open, click on Tools, Internet Options. Select Delete Files to clear your cache. Now go to the Advanced tab. Scroll down to Multimedia. Find Use Smart Image Dithering. Make sure there is a checkmark in the box. Click on OK to close the Internet Options dialog box.
By resetting Internet Explorer settings, you return it to the state it was in when it was first installed on your computer. This is useful for troubleshooting problems that might be caused by settings that were changed after installation. When you restore Internet Explorer's default settings, some webpages that rely on previously stored cookies, form data, passwords, or previously installed browser add-ons might not work correctly. Resetting Internet Explorer to its default settings does not delete your favorites, feeds, and a few other personalized settings. See the table below for a complete list of all settings and information about whether they are reset or maintained.

The text looks heavily artifacted, but thats norm when you save with Paint.
change your refresh rate.

Yeah, how about no?
I doubt the OP uses a CRT monitor anymore.
yeah whatever dude. Changing the refresh rate can help even on lcd moniters. And how about asking your parents to put your gimp suit back on?

Refresh rate would have nothing to do with it if screenshots are showing up blurry also.
yeah i didnt think of that oops

Much of the discussion of refresh rate does not apply to the liquid crystal portion of an LCD monitor. This is because while a CRT monitor uses the same mechanism for both illumination and imaging, LCDs employ a separate backlight to illuminate the image being portrayed by the LCD's liquid crystal shutters. The shutters themselves do not have a "refresh rate" as such due to the fact that they always stay at whatever opacity they were last instructed to continuously, and do not become more or less transparent until instructed to produce a different opacity. Most of the TFT LCDs used in portable devices and computer monitors need a continuous refresh. The driving voltage determines the transmittance of the liquid crystal.
The closest thing liquid crystal shutters have to a refresh rate is their response time, while nearly all LCD backlights (most notably fluorescent cathodes, which commonly operate at (~200 Hz) have a separate figure known as flicker, which describes how many times a second the backlight pulses on and off. However they also have a refresh rate that governs how often a new image is received from the video card (often at 60 Hz).

Refresh rates do matter on lcds.... it saids often at 60hz often being the operative

LCD's don't use refresh rates in the same way CRT's do.
Really depends how far in depth you want to research this subject. You have to consider the connections at coming out of the video card for starters; whether you're going from:
*DVI-I (Dual Link) -> DVI/VGA converter -> Cable -> Monitor
*DVI-I (Dual Link) -> Cable -> Monitor
*Or even VGA -> VGA/DVI converter box -> Cable -> Monitor
Given the exponential growth in technology in the recent years I'd say the OP has a fairly recent system of no more than about 2 years old. So it's safe to say that he/she has a DVI-I (dual link) port on the back of his or her video card, which probably has a DVI-I cable connecting monitor to computer. So assuming that this is the case, we'll run with that.
By definition a refresh rate is
QUOTE
The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for CRTs) is the number of times in a second that display hardware[1] draws the data it is being given. This is distinct from the measure of frame rate in that the refresh rate includes the repeated drawing of identical frames, while frame rate measures how a video source[2] can feed an entire frame of new data to a display.
A few notes here.
1. The display hardware refers to the monitor itself.
2. The video source refers to the video card within the computer itself.
On old CRT monitors adjusting the refresh rate was relatively simple but depended on
1.The rate your video card supports
2.The rate your monitor supports
3. The resolution your monitor is set at. Lower resolutions (i.e. 800x600) typically support higher refresh rates than higher resolutions (i.e. 1600x1200
Adjusting the refresh rate would help you avoid "flicker" on the screen and create a more comfortable environment to work in. LCD's however have a "preset" "refresh rate" which is typically around 60Hz (which is well above the "flicker" point compared to a CRT monitor). LCD monitors produce less flicker than CRT monitors because the pixels on an LCD screen stay lit longer than CRT monitors before they noticeably fade.
But we're drifting too far away from the point now. LCDs are generally rated with "refresh rates" depending on how long (physically) it takes the pixels to shift (from black to white, grey to grey or whatever). It's not some chip sitting there telling pixels to only change 60 times per second, it's the pixels changing as fast as possible. Which is actually more accurate to response time, not actually refresh rates.
Mathematically speaking (still using LCD's), if you have a monitor who's native resolution is 1680 x 1050 @ 75Hz, the response time you can actually calculate using: f=1/t.
Therefor, if the the "refresh rate" is 75Hz, solve for t.
t is about 13.3milliseconds.
Though most manufactures now quote times from GTG to make their product more appealing the the consumer. Apparently, you can just half the response time to get the GTG time and get about 6.6 milliseconds, but that figure is based off a number of "apparent" conditions which will vary from manufacturer to manufacturer. Since LCD are now bordering on the outdated side, most manufacturers will quote about 5ms for GTG transitions and about 2ms when "optimized". Different manufacturers call their "optimization" different things as well. There is a lot more technicalities involved than what I've listed, but I don't have the time or patience to go into it further. The fact of the matter is the term "refresh rate" is (in my opinion) incorrect for LCD technology. Shall we just leave it there?
Just to add, anything below about 10ms is generally considered unrecognizable to the human eye as it is anyway. Although the USAF have been testing pilots by placing them in dark rooms and flashing cards with aircraft on them for about 1/220th of a second and the pilots were able to identify the aircraft. Although it is generally accepted that the average is about 10ms or 100Hz.
