Display reports 70hz max but locked at 60hz and microstutter

[Hickory]

I am having an issue that is driving me nutz.

CCC says my display reports a max refresh rate of 70hz @1650x1050 native res.
However it will not allow me to take it up to the max reported refresh rate. It is stuck at 60 with NO other refresh rate available. I have googled it but am not seeing anything about this issue. I am currently using an HD 5570. I had to downgrade my video card because the HD 6870 i bought isnt preforming as well as the 5770 for some reason. I was getting alot of microstutter with the 6870 (brand new card). Downgrading to the 5770 cleared some of the microstutter up, enough to play again.

My system is all brand new and i have been seeing stutter across 3 video cards in varying degrees, 2 of which were brand new. gtx 260, hd 6870 and hd 5770 with the 6870 being the worst and not benchmarking very well.

Does anyone know how to unlock my max refresh rate?

Could anyone suggest some fixes for the single card microstutter that i have not already tried? (and i have tried all kinda of crazy solution, none of which fixed it or eased it.)

thanks in advance

newegg specs for this display says:

Vertical Refresh Rate
76Hz Max.

i only have 1 refresh rate available at ANY res and thats 60hz even when unchecking the hide res box.

It likely only supports 70Hz for the lowest resolution it supports (e.g. 800*600).

Also, stuttering can be caused by your video card sending too many frames per second to your monitor. You need to use VSYNC in games to lock the FPS at 60 or if you do not want to use it, the game can possibly be configured to run at 59 FPS or less. That explains why "you had to downgrade your videocard, because the framerate was too high."

I know on any of my HDMI monitors/TVs, going over 60FPS causes microstuttering. Wasn't a problem with DVI and VGA monitors I owned.

i have tried this already. actually its one of the first things i have tried was setting it to vsync. my monitor is dvi and hdmi and even vga i think. i currently have it on a dvi cable for my monitor and hdmi for my 50"plasma. my plasma is never turned on, only when watching movies from my pc.


CCC says im supposed to get 70hz with my native resolution. all games i play are in my native res.

im getting microstutter on all games i play and even desktop and watching video.
