Hi, I hope someone could advise me.
A friend (of a friend who should know what he's doing ) recently installed a grahics card for me (Radeon HD6670 PCI Express 2.1 bus (2gb GDDR3)
I did so as I was experiencing distortion, when viewing Vids via HDMI on my TV (tried various media players VLC , classic, Divx etc) Also when scrolling up and down on webpages an annoying horizontal distorted line about 1/4 thick ,making it diffcult to read fluently (if that makes sense :)
I suspect that whats happening is that my PC is still using the onboard graphics (64M) on my Gigabyte (GA-H61M-S2PV)

I normally wouldn't go near the BIOS however I have had a look;
"Init display First" is set to Auto with there being options to set to IGFX, PEG or PCI ......
"Internal Graphics is set to Auto with options Auto, Enable or Disable N.B. on the sidebar it says 'keep IGD enabled based on the setup options'

My questions are : Is it SAFE for me to change the settings ie disable IGD
And what I should I change the Init Display to (PEG or PCI) if indeed I should change them at all

I have to say I'm itching to just go ahead as it all seems so obvious but don't want to end up having a non functioning at all PC, or am I just being too cautious.

Additional info:

he used the install disc and I'm 99% sure he checked for Driver updates as well.
When I looked in display adapter - its AMD Radeon HD6670 says this device is working properly, Driver date 11/june/2012 and there's an option to disable the driver
So I know it says its working ok but why are my display distortion "Exactly" like they were before new grahics? Thats why I thought BIOS as over the years I've read bits and bobs that thats what you should look at

 

Intel Pentium CPU G870@3.10GHz
4GB RAM
64-bit Operating system

Windows 7 Ultimate
Service pack 1

 

I'm using a Samsung 21" LED monitor with a VGA connection and the HDMI to the Samsung 32" and have the problem I've described on original post on both displays.
I have the scrolling problem when I'm just using the monitor itself and when I use TV HDMI for browsing.

I did notice last night that when I'm using 'extend'( i.e. web on monitor/vid on TV) option with dual display (windows key+P) the video's distort when there's lots of movement and panning across, but when I use the 'duplicate' (whats on monitor is same as TV) option it's actually ok with the vids; but still have the niggling scroll when I'm trying to read web pages.
So my reasoning is duplicate doesn't need much graphics power but extend ie web browsing on monitor and putting films on for the wife and 5 yr old boy does.

Would it harm to try the BIOS change? Thoughts?
Cheers Tom and a big thanks to all who've waded through all of the above

I was only thinking of the same or working resolution on both video outputs to monitor since its a VGA (VGA to DVI?) and HDMI connection.

I am curious what the model numbers are on the Samsung 21" LED monitor and the Samsung 32" TVs?

 

I want to look for a manual to those two units and see what the menu settings are for each one. I might find an answer to your problem as to how your video resolution is displayed on those screens.

 

After that, I'll look into your computers BIOS settings and see if I can offer you the best option to try.

 

I have helped others who like to connect their laptops up to their HDTVs and found settings in the actual television its self made the real difference. 

 

Bruce.

Hi Bruce, That's very kind of you . Thanks. :)

 

I had wondered about that , not so much the monitor now as I suddenly wondered if Firefox could be the problem;

So I did a search and sure enough there were a few folk with the same problem

when scrolling using 'smooth scroll'  .

So I've disabled the 'hardware acceleration' in FF (25.0.1) so that there's none of that 'rippling effect lag' as someone described it ,

though to my eyes, a bit choppy but can live with it, I suppose , sheesh, you'd think they could get something as simple as reading a webpage right ?

Then again, maybe there is something to adjust in monitor settings

 

Anyway beginning to rant, sorry.

 

The TV is a : UE32EH5000  - there are 2 HDMI : 1 is just HDMI 2 and the other HDMI/DVI - I've tried them both

 

The Monitor: S22C300H

 

Regards , Tom

Is this distortion like screen tearing that only appears when scrolling?

 

What refresh rate is it set to and what ones are available in the driver?  If it is set to 60Hz, can it be set to 75Hz or 59Hz for example?  Try them and see if there's any improvement.  You might also be able to enable vsync or wait for vertical refresh in the graphics driver.  On mine I can go to 3D settings in CCC set vsync to always on, although I'm not entirely sure if this has any effect outside of 3D applications.  I can't find any settings for 2D unfortunately.

 

If you are using a discrete graphics card you can safely disable the integrated graphics.  I doubt this will do much for the affect you are seeing though but it'll free up some resources.

Hi & thanks for the replies.

Turns out they were two separate issues :

 The 'scrolling screen ripple lag' was a known issue and have found the solution with a Firefox add-on called:

'Yet another smooth scrolling' :)

 

Bruce , you were right about the TV setting - I've you to thank as you got me thinking, so had a look and found:

'LED Motion plus' setting turned it on and hey presto, bob's your uncle, bullseye :guitar:  - Gad I'm so chuffed.

 

BTW did disable the IGD and set init display to PEG with no difference and probably didn't need to change the

graphics card in the 1st place but hey ho I'm happy it's all working

 

Thanks again for the replies

 Cheers Tom :bananas:

 

Edit: Actually web pages seem to be loading a lot faster so maybe the BIOS did  need changing.

I figured you'd find that changing the video settings of the HDTV would resolve part of the problem and the computer's BIOS menus contained the other piece of the puzzle.

Glad to hear that things are working as expected. :thumbup2:
