Full Screen With Your HDMI Cable & ATI Catalyst Control Center

With the new ATI Catalyst Control Center 9.9, I noticed that some options are very hard to find. I actually spent about an hour figuring out how to change the scaling options for my monitor since the button was really well hidden.

In this quick guide I will show you how to set the over and under scan options for HDMI so that you can watch your HDMI in full screen.

Full Screen with HDMI cable

This blog came about because I was having trouble getting that 100% full screen with my HDMI cable connected to my 1080p monitor. When I connected my HDMI cable the screen was being centered on the monitor and not taking full advantage of the screen

The Fix: It is actually quite easy to fix this problem and get your full screen with the HDMI cable. All you need to do is adjust the over and underscan options within your ATI Catalyst center (also known as the Scaling Options).

ATI Catalyst Control Center 9.9 Overcan and Underscan Options – Image Tutorial

Surprisingly, the over and under scan (scaling options) are quite buried in the new ATI Catalyst Control Center. But if you know where to look the scaling options are really easy to get to…

To get to the ati scaling options do the following:

  1. Right click on the Desktop and open Catalyst Control Center 9.9
  2. Switch to Advanced mode if you are not there already
  3. Click dropdown menu Graphics in the top right
  4. Select Desktops and Displays
  5. Right Click your currently activated display under ‘Please Select a Display’ on the bottom right
  6. Select Configure
  7. Click on the Scaling Options tab  and your there
  8. Now, just move the scale to the right (overscan) until you get full screen (in my case that was 0%)

This process should work in windows vista as well as windows 7. I am currently using my HDMI cable on windows 7 RC with 0% underscan and with an HD4890 FX graphics card…and it looks beautiful!

I hope this post helped!

    Thank You very much for this topic, it helped me a lot, I was f-ing with this issue all the afternoon with my new HD6850, it came to that situation that I had to reinstall the system (after driver uninstall) :/
    Hopefully I’ve found this topic, cause I was starting to think that something is wrong with my hardware.
    What a stupid idea to hide such an configuration under right mouse click on the bottom display thumbnail!!!

        Hi, I just hooked up my HDMI cable to my monitor and now have shrunken screen as well. I went through your directions, but I have Catalyst 10.8. the screen shots are a little different. Can you help get my full screen back.

        Thanks, Joe D.

          On the newer versions of catalyst, this setting is under “My Digital Flat Panels” in the “Scaling Options (Digital Flat-Panel)” section. The over/underscan options only show up if you have the display set to 1080p, so set it to 1080p first, then go to the My Digital Flat Panels section and change the setting.

          Jason, how do you set your display as 1080p to get the options to not be grayed out? I’m trying to update to 11.12 but the slider bar is disabled.

      Thanks for the help. My only problem is that everytime I play a game I have to rescale. The settings dont change at all but I have to go into catalys control center and that bumps it back to full screen

        Hey. The Catalyst Control Center offers the ability to have different display profiles I believe. I would recommend using “UltraMon” for multi-monitor displays. I have a gaming (single monitor) profile which turns off my second monitor, a gaming dual monitor profile, and a default profile. It works out very nicely.

    It worked like a charm! Thank you so much :) I had to connect it via dvi to get the whole sized 1080. Catalyst Center is a pain in the *** to figure out but it’s so cool with all the tweaks you can do. ATI FTW! For those interested, I just upgraded from my old 4670 to a 6850. Reviews said that the 6850 made loud fan noise and that is not true. Compared to my old 4670, I can barely hear it. My gaming rig had serious competition (noise wise) with the xbox lol! Not anymore :) Oh, and the graphics now is just stunning. The picture is so clear and sharp with so much detail. Currently playing Battlefield BC2. Dirt2, and Warhammer Choas Rising.

    Hi,
    I am also having the same problem. When i change the scaling options everything works perfectly and i can take full advantage of the game. But ! Whenever i open a game or something that changes my resolution inside the game it snaps back to its former scaling size with black empty space around the screen. And even when i close the application/game etc. and return to desktop its still with black space around the screen. When i go back to scaling options at cataclysm control center i see that also the slider snaped back to its place.. No matter how many times i fix it whenever i launch an application that changes my resolution it snaps back to annoying empty space around screen size. Please Help me ! I’m going nuts ! And everything was workign perfectly fine before i format the computer. I did downloaded the latest version of the Ati Graphics driver.

    I have an LG Full HD 1080p Screen 32″ and Ati HD2000 graphics Card.

    I have had the same problem as Sarp Serter. Changing the scaling to 0% temporarily resolves the problem and the image fills the screen, but after a few hours, it reverts back to the previous smaller size of image. I have a Radeon HD 4500 series and a 22 inch Asus LED monitor. How can I make the scaling changes last for more than a day?

    Why on earth do they revert this setting when you update the driver!!!

    Why on earth do they hide this setting????

    Why on earth do they underscale by default??? (realize there might be a good reason that has something to do with TV’s or whatever)

    Jessie, I have the same problem where selecting “configure” takes me to the information page. This happens on version 10.10 for me; v10.12, 11.1, and 11.2 are even worse, they only have one option under the graphics menu, called “Displays options” where I can’t do anything really.

    Customer support is having lots of trouble with this, I’ve spent 3 days pulling my hair out

    Anyone have a solution?

      That’s funny if you want a lot of options, use ATI. If you want no complications with limited options, use Nvidia. Nvidia is playing safe with only options they think will work on all products.
      ATI= for Advanced or Experts only.
      Nvidia= for For Beginners only.

      And thanks for info Joe. Remeber people to disable scaling from tv set too and ClearType in windows 7 (i don’t don’t know about vista’s clear type option). I got wrong picture with scaling on my laptop + my Philips TV and clear type option on.

    Imagine even coming up with the idea of setting some random underscan as a default, and then hiding away the setting to fix it.
    (Or leaving it out entirely for some cards)
    J…F…C!

    Those idiots keep dropping their pants and squirting out thesa ridiculose drivers and UIs.

    There must be some kind of low IQ requirement to be hired as a programmer at ATI.

    I couldn’t find version 9.9 so I downloaded version 11.6. As you can expect it is somewhat different.
    But the setting is still under scaling options plus I had to set the underscan/overscan value to about 8% as the 0% made the screen TOO BIG and I lost about 30% of the display, all the gadgets were off the screen.
    But it eventually worked…. :)

    Hi guys,

    I seem to have the same trouble as some of you are having.
    I have the AMD Vision™ Engine Control Center 11.6,
    with a AMD Radeon HD 6250 card but when I attach my LG32″ up with HDMI, I get a very clear picutre but have the black borders.

    I searched and found suggestiosn on underscan/overscan but no such options exist in this control centre version.

    What has also been suggested is a simpler “Scaling options” under My Digitial Flat panels. I don’t get this option unfortunately.

    Does anybody know if this may be a driver issue perhaps? I have the latest drivers :(

    Any help would be greatly appreciated!!

      I,

      Sorry for my english but i’m portuguese.

      I found the solution after many tries… and it’s so easy to do…

      FOR THOSE WHO HAVE CONTROL CENTER 11.6:

      1. set your screen resolution to um value lower than highest. to do this simply right click on your desktop,choose screen resolution and change resolution in resolution box.

      2.now go to ur ATI catalyst control centre.to do this,right click on desktop and the top most choice is ATI catalyst control centre.

      3. choose proprieties of integrated videos (something like that), and select the option: full screen.

      4. Click “Apply” & then “Ok”.

      5. Now change back your screen resolution to original (following same method like the first topic).

      After this, run a game that you wanted to play in fullscreen and see if it works.

      Hope it helps! This is working for me.

    Yes, now my display from my media center is filling a whole my flat panel area (using HDMI cable).

    But … this is still not perfect :/

    Try to use any tool program to display monitors and panels (I used a program named “Monitor Tester 2.1″ found on softpedia site). This program can display (for example) vertical or horizontal black and white lines 1 pixel width. This program is showing that display is not perfect, because – as I understand that – display on the flat panel is NOT displayed using *native* flat panel resolution but is scaled somehow in the middle (scalled by ATi card? FullHD panel?) :(

    Mayby, to get perfect aspect ratio and perfect digital display, I should use DVI cable to connect my mMedia Center with my FullHD flat panel?

    Hi

    I experienced this EXACT issue while still using my old Acer 23″ LCD in combination with my old ATI Radeon HD 4870. As mentioned above, the scaling (under- or over-scanning) option did resolve my issue 100% then.

    In the meantime I have purchased a larger Samsung 27″ LCD and an ATI Radeon HD 5870 (also went CrossFire recently), only to find the issue reappearing again. So, thinking I am already aware of the fix I changed the settings from -15% to 0%, only to find the display is now TOO BIG for my display and that it gets cut off like “Louis” was experiencing. Changing it to bwtween 4 to 8% made the picture fit in better, however I still have a couple of mm border around the edges like “waijun” was experiencing.

    Also, no matter what the scaling slider is set to, the image always stays out of focus and seems fuzzy and not crisp. I experienced this too with my old LCD and old HD 4870, however got corrected when the slider was set to 0%. Now however, NO slider setting fixes the scaling 100% correctly.

    Anyone please?!?!?!?

  53. TESTCTV
    This was Posted on

    I managed to resolve the issue myself! I was a combination of both the Catalyst scaling option (under-/over-scan) in conjunction with my LCD’s own settings:

    MENU > SETUP & RESET > *scroll all the way down * > PC/AV MODE > *change option* > PC (was on AV which was the issue)

    After that change on the LCD the scaling option under Catalyst fixed the rest when adjusted to 0%

    http://www.avsforum.com/avs-vb/showthread.php?p=20917201#post20917201

    Cause I had issues with driving LED TV’s in a store (tried a few)

    like you said, the picture was centered and not taking the full screen.

    We did use the “fix” you describe, however, that does not make the picture a 1:1 pixel match. Cause its a slider, you either end up over-scanning a tiny bit or under-scanning a tiny bit. we made it to within 2-3 pixels on each side, which is ALMOST taking up the full screen, its not even visible that its ever so slightly NOT the full screen.

    But this is a serious problem, because for a sharp picture, you need exact 1:1 pixels used to avoid the TV from recalculating your input.

    Example: if you’re displaying 1920×1080 pixels on your 1920×1080 LCD screen, but you’re not using every pixel, being off by a single pixel, like using 1918×1078, or over-scanning to 1922×1082, the TV is going to re-calculate your image, with the result, that any text displayed looks like dog food, cause computer fonts need to be pixel-accurate to work.

    I realize that your method works sort of ok for games and movies, but its no solution to use, an LED TV as your full time computer monitor…

    I had fixed the scaling with a previous version of ATI CCC. But even though I knew what I was looking for I could not find the scaling options anywhere – what a terrible UI they designed.

    This may have been already answered but I missed it, can you help me do the same on my tv? The screen went to a traditional view when I switched to a HDMI cable.

    Hey AJ,

    Thanks a lot for your tip on the overscaling.

    I’m a fresh owner of a new LED 3D and I didn’t know how to fix my resolution. Thanks to you, I did it in 2min.

    Cheers

    Champion. I’d been looking for this option for a while. What a ridiculous place to have the over-scaling settings, no wonder so many people are having difficulty trying to find how to fix it, because the option isn’t in plain view.

    Also AJ your point 3. Click dropdown menu Graphics in the top right
    is actually in the top left.

    Thanks for your post.

    I had a hitachi tv, just bought; image exceed screen; i took tv back, bought a vizio.
    THEN I found this thread (as vizio did same thing), and today I’ll experiment with fixing it

    QUESTION
    for an ACCURATE change to the over/underscan, is there a REGISTRY setting that controls this?
    I did look into the registry, (HKLM/system/currentcontrolset/control/video….)
    and the ati settings reside there, per monitor (can’t make out which is which)

    BUT, there is one setting that is an “tvEnableOverscan (something like this) which seems to want a “0” or “1” value.

    would this fix the problem, or is ther an exact setting that determines amount of overscan?

    thanks

    Just added HDMI cable to replace the DVI connection and experienced the same truncated screen size. Then updated my ATI video driver and in the latest Catalyst Control Center, typed in the word “overscan” in the search box, which then provided a link to the scaling box in Catalyst Control Center. I then was able to follow the directions provided by this web page and to scale my monitor area accordingly to where the display now fills up the entire monitor area.

    It doesn’t seem to work for me. I went through the screenshots and everything looks the same except the scaling options section; everything is grayed out, but it is on 0%. I still have the black space around my screen.

    My monitor is attached to my laptop via a HDMI cable and setup as an extended screen. Don’t know if that has something to do with it.

    I have a 24″ ASUS monitor. I bought a new laptop and also an HDMI cable so I could connect the laptop to the larger monitor. The HDMI is not showing on screen when I plug in the HDMI cable. Also when I press the toggle button and F8 the monitor does not change on either my 24″ or laptop. All connections are in properly because I checked it. Also, I don’t have the CCC option when I right click on my desktop. What am I doing wrong? Did I buy the wrong HDMI cable? Can you please advise?

    I have an ATI Radeon HD 4570 video card in my Sony notebook with Catalyst Control Center 11.10.25. My Panasonic TV has a black frame (border) via HDMI connection. :-( Unfortunately, I can not find the solution in the configuration option, in CCC 11.10.
    (On TV overscan option is ON.)
    If someone could help would be very good.

    I used my AMD Vision Engine Control Center (latest 11.12 version) with my Radeon HD4200 embedded ATI GPU and my Philips 32″ Led Monitor/TV to have FULL panel image … so I put UNDERSCAN to 0% and everything went OK.
    But surprisingly after Screen Saver “session” the screen became smaller again and I found that VECC took Underscan to 15% by itself …
    How can this be fixed ??
    Anyone can help me ??

    Thanks

    I’d already wasted about 90 minutes trying to solve this problem after upgrading from WinXP to Windows 7 (which required me to install new catalyst drivers). I’d been making a brute force pass through every conceivable option and tracking my progress with pen and paper. After 90 minutes I thought I’d passed through the entire user interface. Wow. Usability nightmare.

    Much praise to you for finding this and publishing it.

    The output quality of the ati card in the E350 is for dogs and pigs not for human beeings what a horse sh#t.
    Upscaling does not disable screens dsp to scale and sharpness is g0ne.

    To Reece and anyone else with a grayed out slider:

    Go to My Digital Flat-Panel>HDTV Support (Digital Flat-Panel) there you will see a list of display formats like: “Add 720p60 format to the display manager”

    YOU MUST check the correct line that matches your display settings in:
    Desktop Management>Desktop Properties.

    For example, my LCD flat tv screen is set to 720p @ 50Hz refresh rate for best picture quality, so I had to select 720p50 as explained above, and only then the previous grayed out slider became functional.

    Good luck to you all.

    After brought back home and connect to my daughter’s PC and turn it on, the picture appeared like it used to appear on the 20 inches monitor. I have tried a lot to make it full screen, but can not, due to the Window 7 command which is confusing.

    Then I have googled to find this blog I then followed your instruction above immediately, and it was really fix the problem without distorted text or photo, but instead, it has made text more shape and sharp, photos were more beautiful.

    When I first started using the screens there was “overscan” – the edges of the picture did not quite fit. . On the media PC it was mildly irritating and I tried fixing it with the “underscan” setting in the system preferences.

    This was far from ideal since it lost some of the crispiness. In the end I just accepted that I could not see the status bar on that computer if using that screen .But with the new office screens that was not acceptable. This weekend I invested a bit of time in the monitors’ options and found the answer: by default they all are programmed to “zoom” slightly. Not sure why that’s the case but it is possible to tell them to just display what they are getting on their HDMI imputs pixel-for-pixel. I must have navigated around the menus several times before stumbling across the necessary setting, confusingly masked by a picture size/aspect ratio setting of 16:9. Apparently in screen manufacturer land, 16:9 actually means “chop off the edges”. Who knew!

    Anyway, on the LG you press menu then go into “Picture” then “Aspect ratio” and change from “16:9″ to “Just scan”. On the Samsungs it was Menu -> Picture -> Screen adjustment -> Picture Size, then change from “16:9″ to “Screen Fit”.

    Now I can have a reliable connection between my laptop and my LG TV connected via HDMI without having to play with catalyst settings and drivers.

    Good luck guys.
