Your TV is re scanning/scaling the image you need to see if your TV has a pc mode for HDMI or a "just scan" option in its settings.

Nb. Not all TV's have these options.

That image doesn't seem blurry. You'll have to take a photograph of the screen.

Is Windows set to the native resolution of the display? Are the edges (such as the taskbar) cropped out (usually a sign of under scan issues)?

I see why you're having blurry issues. You're using 1024x768, a 4:3 resolution, when HDTVs are widescreen (16:9) and support either 1366x768/1280x720 (on "720p" tvs), or 1920x1080 (on "1080p" tvs). Set your resolution accordingly. Using 1024x768 on any HDTV would be a no-no, since the HD standard on televisions is nearly always widescreen.

Using a screen resolution that does not match the exact pixel dimensions of an LCD screen will cause it to have to upscale/stretch the images to fill the screen area, resulting in the fuzzyness.

If it's recommending 1024x768 for your HDTV, then windows is not detecting your TV's supported modes properly. If it allows you, try setting it to 1366x768 (or if not that, 1280x720 that I think some older 720p sets used). I doubt your TV would be 1080p, since it's only 19"... but stranger things have happened.

Try different ones I guess. Try 1366x768 first since that would usually be the top match for a 19". If you get a blank screen or something, just wait like 20 seconds or whatever and it should return. If your 19" is older, it could potentially be 1280x720, but in that case you wouldn't be able to run metro apps. 1366x768 would be ideal, unless that 19" supports 1080p which i doubt. lol

huh?, run true 1920 x 1080 HD or forget it. People just don't get it, only experience worth anything is a 1920 x 1080 signal fed to a 1920 x 1080 screen, anything else is really garbage!

His TV is a 19" and likely won't support the resolution.

Weird, is this really an HDTV? Are you really connected via HDMI? This sounds more like a display being connected via VGA.

If 1920x1080, 1366x768, or 1280x720 don't look right and it's an HDTV? I don't know what to tell you. Now if it was a computer monitor, it could be 1600x900 or 1440x900 as well.

Do you know the exact model number of your TV?

Hello Mansonx,

Since you have AMD graphics, you might play with the scaling options a bit to resize the display of the selected TV, then click on Apply. I have the steps numbered in order in the screenshot below to help. You may or may not need to use 4, so try with and without to see how you like it.

I'm not sure if that works. I've had a problem where my 42" TV automatically underscans anything transmitted over HDMI, and fiddling with he scanning on my computer just gave me a blurry picture. Using VGA solved the problem, but made my Bluray drive useless.

Right click on your desktop, and click on Catalyst Control Center in the context menu. From there, open the same settings in the screenshot.

If that doesn't help, then clicking on the Defaults and Apply buttons in the screenshot will restore it's default settings.

Ok. First, click on the Preferences button at the top right corner, then click on Advanced View.

Afterwards, go to the same location as in my screenshot. Next, click on the arrow (#2 in screenshot) and select your TV.

I upgraded my father's PC from its ancient Intel graphics over VGA to a nice AMD/ATI 6450 card over HDMI and experienced this blurry text.


Some things you need to do:


Most TV's have a lot of postprocessing over the HDMI ports. This is what makes your movies and TV look great. However, processing the image on a PC is a no-no. You want the image to look as what the PC is intending the image to look as. So you need to make sure that for the HDMI input is set to a "game" mode or some equivalent mode where there is no postprocessing. If you connect over VGA, manufacturers do not process the VGA input so it looks like what it's supposed to look like and there's no "game" mode as it's unnecessary.


Now you also have to adjust your ClearType settings for this new monitor/TV. Run the settings wizard for ClearType.


You have to adjust your various settings in for your graphics card. Brink has a good pic. Now play with the settings because there's no one set of settings for every display device.

Under My Digital Flat Panels, there's a Properties tab. And under that is GPU scaling and ITC processing. For my father's system, I enabled both of them.

Under the scaling options tab, I've enabled "use the scaling values" and I set overscan to 0% so that the screen takes up the whole screen.

Under Pixel Format, I set RGB 4:4:4. Now this is personal preference. Another pixel format might look better for you.

And I guess the last thing is to know what your true resolution of your LCD panel is. If you have a 720P TV, you have to run your desktop at 1280x720 to get the sharpest image. Similarly, if you have a 1080P TV, you set your desktop to 1920x1080. For example, if your panel is 1440x900, then running at any other resolution besides this resolution will be blurry.
