Re: T520(4240) Video Lags

2013-02-21, 17:27 PM

Dear dmckenzies,

I HAVE FIGURED OUT THE PROBLEMS!

Though it is not entirely fixed, but it is working, I will explain.

I have to credit you for putting me on the right tracks.

 

 

• Password issue for the Lenovo Rescue and Recovery prompt.

  (safe boot, back to factory settings procedure).

 

solution:  

- Creating a new user with administrator rights, without passwords,

allow me to get into the restor to factory settings.

 

persistent problems:

 - Changing my password on my own windows session, do not solve the problem.

 So there is either a default password which I dont know, or another issue.

 

 

• Video lag, delayed pixels, issue with graphic display.

 

problems:

- while playing videos online, or media player other than Windows Media Player or Windows Media center,

a delayed lines of pixels appears, only when objects moves (on the video). It also occurs on some  features on websites (smooth fading, gifs, flash related effects).

It occurs as well on some video games, with heavy graphics.

It occurs on software with graphic display, such as photoshop and illustrator, while manipulating images. The same lags happen.

- Do not occurs on Safe mode. Do not occurs with Windows Media Player and Windoas Media center.

 

solution:

Turn on the Windows Aero mode, or the Think default, or Think_theme.

Basically since the beginning I was using the High Contrast default mode. Any of theses theme will generate these lags. This is why I linked this issue with the first time I got my computer. Because I dont like Aero mode so much, I was using the other which I find more neutral. Since then I restrain some of the features on the Aero mode and its working fine! 

But yeah, it is still present on the High Contrast mode.

 

Maybe try this at home, and see if you have it. If you do, then it is related to Windows. If not then I dont know, I will look online for conflict with Windows themes.

 

Let me know what you found!

 

Thanks,

Machin

_Machin_,

 

I would not have thought Aero would have been the solution.

I had someone else with the same issue where the problem was Aero...interesting...

One man's problem is another man's solution.
