Adjusting BIOS after installing new graphics card

by tomncar / December 3, 2013 6:43 AM PST

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 memory)
I did so as I was experiencing distortion, when viewing 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 .
I suspect that whats happening is that my PC is still using the onbard 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.

Thanks for your patience in reading this Tom (uk)

Hi, Just an update.
I found out from the tweaktown forum that it was safe to disable the IGD (onbard graphics/video) and set 'Init Display' to PEG (express bay) It made no difference to the 'scrolling ripple lag' I was experiencing on web pages but did make them faster to load. Also no diff to HDMI to TV display.

On the 'Bleepingcomputer' someone suggested it might be the TV settings itself , so buried in advance settings I found and tried a 'LED Motion Plus' setting switched it to on and hey presto , no distortion.

Also found out that the 'scrolling ripple lag' was a known issue with firefox 25.0.1 and earlier vers. I believe - I found the solution to that with an add-on called 'Yet Another Smooth Scrolling' Apparently it works with Chrome too though haven't tried that as I like my Tabs on the bottom and only FF do that AFAIK.

So there you have it - Thanks to Digger again for getting me started

Cheers, All the best Tom

Why Bios?

Have you looked into the device manager and disabled the onboard graphics?....Digger

Thanks for the lightening reply. Just looked at 'device manager' but sorry, I haven't a clue where to look for that Blush .
I'm using Windows 7 ultimate btw. where would I find that setting?
Thanks Digger

Well, You go into
by itsdigger / December 3, 2013 8:05 AM PST

the device manager and you'll see Display Adapter and click on that and it will show the drivers being used. Didn't the new graphics card come with an install disk? ....Digger

Yes the friend used the install disc

In reply to: Well, You go into

Yes Digger, 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 that 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-
What do you reckon? Cheers Tom

Bit more info

In reply to: I recon

Hmmm , 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' 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' option it's 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?

Funny when I read your post Digger. Thougt you said 'Go' into the BIOS till someone else comes along hehe
I've copy and pasted the question onto 'Bleeping Computer dot com forum to see if I get a response.
So thanks again cos now I've given all the info I can think of.
Been wondering if I should install 'Belarc' or 'AIDA' ;suppose I'm trying to avoid any the hassle esp as every bit of freeware seems to try to install toolbars ,search engine etc these days

In reply to: Tell us the

Apart from the mobo/processor/graphics card I don't know as same guy put it together himself- he works commercially in computers on short contracts but more information/data I surmised.
I'm sure he knows the main stuff, but I've noticed he's surprised at little things like About:config in Firefox
I'm still thinking that probably 95% of the time the onboard graphics would have automatically been disabled but this is just one of those times when it's needed.
Kinda glad you said not to chance it - Almost thought throw the dice and see what happens haha

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
