New Ati 4850 problems in Win7

Hello to all,

I`m new to Win7 and this forum, ofcourse :) but tis good to see i have a place where to ask for help and maybe even fix something.
Before i upgraded to a Ati 4850 i had a nvidia 9600GT that worked fine...in Vista. When i got the 4850 i did a clean install of Windows 7 build 7100 RC .
I installed all the new drivers for mobo, audio, graphics etc...defraged, installed antivirus and my ussual programs and games. All ok ...
...ultill i played my first movie in VLC, its very pixelated. Other players work fine, just VLC is pixelated, i looked around its settings but nothing helped.

Another problem i discovered and its big, I cant use 75hertz on my monitor.
If i use 75 i get flickering red dots all over my screen, in my desktop or in games. Its very annoying since most games come with standard 75hz i have to manually adjust them in regedit to use 60. 60 works great. Before the 4850 upgrade i could use 75 with my nvidia card.

Another problem i cant explain is somewhat bad performance for my video card. Ofcourse ATI drivers for win7 now are bad but still i get same performance i got with my 9600GT. Around 9500 points in 3DMard06. Same score i was geting with the 9600GT. Still posibly my CPU is draging me down...but still thats to much draging down ...:)

Hopefully the new 9.5 Catalyst drivers will solve some issues but in case they dont , what will i do ...

Any advice or help, maybe you seen these problems before, i dunno ... plz tell me

Well, I am not sure to help ... but, try this forum post : AMD Game Forums - 4850 / Windows 7 /after installing 9.4 Lost 75hz Refresh

I think it is a driver problem at all ...

Well can't help on the refresh issue, but I can reccomend Smplayer inplace of VLC. I watch all my avi's divx etc on it - without issues. Comes with all the codecs I've ever needed.

SMPlayer - Downloads

Maybe give it a go unless you really need VLC, for streaming or somthing. (Though I could never get streaming to work with VLC or anything else for that matter)

I have the 4850 and have the exact problem with VLC. I also have over heating issues with the card in Windows 7 that I did not happen in Vista.

Hi shanghei. What program do you use, to cool your card.?

I use the Catalyst control center. I leave it automatic control which always worked in windows vista without problems.

9.5 are out, maybe they will fix your issues. Goodluck.

Ty , i`ll surelly give it a read. About the VLC issue, i replaced it with WMP Classic Homecinema, heard it plays best 1080i formats.

Luckly i dont have a cooling problem cause of the his iceQ4, it really stays cool and GPU fan always at 2% cause of the heatpipes. Sux the drivers are infantile.

Yes i was downloading before i gor email notification from then i read. Tyvm anyway :)

i`ll report back.
