Okay, i got dell lcd (max resolution : 1280x1024 60hz)

keeping display settings to native causing strange screen lining going upward...but forcing refreshing rate to 75hz from display driver manager have remove some of it (not completely) but bearable...

My question is that if i should keep this setting or there could be problem in future because i think my lcd monitor does not support that refreshing rate but somehow its working, i also want to know to know that if it cause fps drops while gaming...

thx...

If you can get a HDMI cable (hdmi->hdmi) you should try with that. See if you can borrow one at first before spending money on it.

The 75 hz represent the refresh rate on your monitor and not the fps provided by your video card, so no; running a monitor in a higher refresh rate won't drop your fps in gaming or in other applications.

What you also should try is to enable Vsync (vertical synchronization) in you catalyst control center to see if you have a screen tearing problem, which I suspect that you do. Vsync will force your GPU refresh rate to sync with your monitor's refresh rate. Before you do this though, you should go back to 60 hz on your monitor.

The reason why I suspect that you have a screen tearing problem is because you...

I think that your problem may be solved if you can change the cable to HDMI instead of VGA. The 7750 is a good card but will probably be struggling at 1280x1024 with only 1 gb vram depending on your graphic settings in the games.

If your monitor supports hdmi input I would try a HDMI cable. Borro one from a friend if you don't have one lying around.

Vsync will force your GPU refresh rate to sync with your monitor's refresh rate. Before you do this though, you should go back to 60 hz on your monitor.

The reason why I suspect that you have a screen tearing problem is because you are able to minimize the lines by changing the refresh rate on your monitor, which may suit the refresh rate from your card a bit better if the feed from your card doesn't sync with your monitor automatically. This is also why I want you to try to change the cable as I supects a normal VGA cable may have trouble providing the data fast enough when running 1280x1024.

Other things you should try/do:
Update your drivers for your video card.
Update your drivers for your motherboard.

@Mahisse 1GB is more than enough for 1280x1024 for ANY games. I can comfortably use 1440x900 on my 1GB GTX650 card.
@OP Could be a monitor problem too. Is there anything near your computer which emits a electric or magnetic field?(Such as a large magnet or the case kept next to the monitor; bad power supplies emit electrical noise). Try using a different VGA cable.
