ATI Catalyst Control Centre....help needed.

[piston broke]

Hi Everyone,

I have my PC (running XP Professional) connected to my 51 inch Samsung TV via HDMI lead.....

i was getting a 1/4 inch black line round the picture, so i installed the ATI CCC and adjusted the scaling, which solved the problem - the signal from the computer now fills the entire screen - BUT, there is now 1/4 inch of shading round the edge of the screen - i can see the picture below, but its pretty annoying having the shading

Any ideas how to get rid of the shading ??

thanks in advance.

This might be an artifact generated by the display screen.

Is this a TV, or a Monitor?

What HDMI resolution are you using?

What resolutions do the TV/Monitor support?

Sometimes getting a correct picture and aspect ratio is a combination of setting the PC and using the TV/Monitor onscreen settings

Had a similar issue connecting my laptop to my Samsung, had to fiddle with a combination of the laptop 50/60hz setting and the Samsung on-screen menu display setting/options.

I think the shadow may be overscan. Try returning that scaling to normal and see if another setting adjusts size/position.

if i adjust the scaling - the shading goes, but the black line returns.....so back to square one.....

Try adjusting the TV picture size from your TV's remote control. That's what cured the problem on my Pansonic 50" plasma. I have about 7 screen sizes available including 4:3, 16:9 and various degrees of zoom. Zoom 1 fitted the entire picture on the screen. I never had any lines or grayed-out areas though. What video card are you using? Have you installed the latest drivers for it?

tried adjusting and latest drivers - no joy...

Since your TV is a plasma, the shading will probably be burn in from the previous black border.

Normally your tv will have a setting where you can " white wash ": the screen, and the shading will disappear.

If you have used the black border for an extended time, something like several months, on an older model plasma, there is a risk that the burn in is permanent

Maybe you should try it. Merry Xmas.

This seems quite likely.

One quick test would be to connect a stand-alone DVD player or similar, or tune the TV to a regular TV channel. Or even play a media file from a USB drive if the TV supports this. If the shading is still visible with these sources then it will indeed be screen burn.

Thanks for your response KK....

my set up is (1 bed condo)...the computer output goes via HDMI into a powered HDMI splitter box, one output then goes into the main TV (Samsung 51 inch), the other ouptut goes into the bedroom to a 42 inch samsung [lasma TV)....

the second TV is used mainly to Thai TV.....but when the second tv is put on with signal from the computer, there is still the shading and the shading isn't just round the edges...

so my conclusion is that its the signal from the computer rather than the TVs.....

the shading really has come since the CCC was installed....

Fair enough. I didn't understand that from the earlier comments.

I used to have an underscan problem on my plasma screen but rather than use the scaling option I just created a slightly different custom screen size in CCC which worked fine. Since using the same video card and drivers with a new LCD screen I no longer have the problem on the default 1080p settings.

It may also be something to do with your HDMI splitter box. Could you connect the PC directly to the the screen to test that?

tried direct connection, still the same......

Piston, have you tried KittenKong's other alternative, setting CCC back to default and then setting a custom screen size (custom resolution)?

tried all options....the default is the best, but problem still there.....

Well, with the TV settings and the splitter being eliminated as the cause of the banding and gray box on your picture, that seems to leave the ATI video card as the source of the problem. Is your PC rather old? What is the model number of your ATI graphics card? How big is your power supply? Could you borrow a different ATI card somewhere and try it in your machine? I wonder if XP Pro might be getting too outdated. MS and probably most developers will discontinue their support of XP soon!

thanks for your reply No 1....

Reply as follows:

its a Compaq desktop, just coming up to 4 years old.

my graphics card was replaced recently as the original one's fan gave up the ghost and the guy in the shop changed the whole card.....it now has an ATI Radeon HD5450 (according to the CCC that is)......

can't really borrow another card - would be too scared to open the back of the computer, in case it broke !

i did think of upgrading to windows 7 when the computer guy changed the card...his attitude was if it ain't broke.....also he said that it wasn't an upgrade - you had to take off all the files etc then re-install once Windows 7 up an running....my fear was that with all the faffing round, there would be loads of problems (far greater than my shading problem).....

power supply ? - the computer is plugged into the mains via a surge protector....

hope someone can shed a light (lol) on my shading problem...

Piston broke: Your machine isn't that old and the ATI HD 5450 is a decent graphics card. The power supply is the device inside the computer that converts your AC current into DC current to run your motherboard and peripherals (cards, drives, etc). If the original graphics card in your machine required less juice than your 5450, it may be that Compaq just put a 300 watt power supply in the machine. Depending on what you have in the machine, you may need a 400-500 watt PS now. Without seeing your machine personall!y, I can't diagnose exactly what is causing your video problem but in the HPs and Compaqs I've owned in the past, the first thing to break was the power supply. HP (which makes Compaq machines) uses cheap power supplies. It wouldn't hurt to have a local shop test your power supply and also calculate how many watts of power your machine needs to run without strain. It's good to have some overhead of around 100 W. Regarding Windows 7, you're going to have to bite the bullet before long. When you get around to it, it would be good to backup all of your data files and do a fresh installation of Windows 7. You'll need to reinstall all of your programs, but a computer shop could do that for you. I don't remember the exact date but Microsoft will stop supporting XP before long. You need to have an OS for which regular updates will be available. I don't recommend Windows 8 at the present time. Good luck!

blimey this is starting to get complicated !

i'm going to try and see if i can get a teccie to swing by and see if they can shed some light on it......
