You remember the temperature problem? and remember that my lappy has two modes i.e. STAMNIA and SPEED and as far as I know, it has an onboard video card plus this NVIDIA card which activates if the SPEED mode is on (or maybe I'm wrong but anyways when I'm in STAMNIA mode, I don't have that temperature problem even when I watch full screen movies with my 22inches monitor having the lappy connected to...
The point is that the lappy does not allow me to use the HDMI cable in STAMNIA mode...something pops up and asks me to switch to the SPEED mode....
The model of my VAIO belongs to the states and their support sucks in Canada as well as the warranty is already expired anyways...
PS. but I really decide to buy a PC in near future if procrastination leaves me alone

Hi, I guess we need to look at just how SONY have implemented this?
It would seem that "SPEED" uses the independent video card and that "STAMINA" uses the onboard chipset?
It may well be that you don't have a problem with the D_Sub connection..........it's just that the onboard chipset cannot handle the 22" monitor?
If you use the HDMI then you get overheating............that shouldn't happen as the box is obviously intended to be used with an external HD monitor for gaming?
I would suggest that you access an external monitor using D-Sub, and see if that flickers. If it doesn't then it means that the onboard chipset cannot handle the 22" monitor and there is nothing wrong with your D-Sub connection.
Have you gone into your BIOS and Vista and checked your monitor settings try them on power saving rather than performance. Also have the fans always on at full speed. Check to see if there is a difference.
I am guessing that the onboard video chipset is also nVIDIA??????????? in which case you might have a solution from them. They do a thing called "SLI", which is for dual chipsets in a gaming environment. This may let you use both chipsets at once by overriding the SONY instruction set.
Try updating your nVIDIA software (nForce?), and look for an implementation of SLI.
Good luck

I have been with the secondary display on the laptop to use mobile units, such as VGA cable problem. I do not know if the VGA cable line is easy to bend or break, but I've been with the VGA cable problem...

Hello luluxiu and welcome to AO.
I do not know if the VGA cable line is easy to bend or break
The actual cable is very strong and flexible, the problem is usually with the connectors.
This is not so common with a desktop machine as you attach the cable and leave it there. With a laptop you are constantly plugging and unplugging the cable so the chances of damaging a connector are greater.

Problem Solved
Flickering problem solved
OOHHHHH my gooddneesssssssssssssss
I don't know why I should come across this now after such a long time struggling but anyways I figured googling laptop+vga+flicker a couple of days ago and I did it and ran into this website:
http://forum.notebookreview.com/tosh...n-flicker.html
There it was suggested that the problem is because both monitor and lappy are hooked up to the same plate and running the lappy on battery might help. So I disconnected the power cord and flickers disappeared
I tried three different plates in my room but it didn't solve the problem so I guess the problem is with lappy running on power cord anyways...

Hi there boyboy, many thanks for the feedback, which I find most interesting!
Like yourself I have a US sourced laptop (Compaq CQ61US) so I will try it on my Samsung 23.3" and LG 21.5" screens. Over here we use 240~250v 50Hz on 13amp ring mains, so I have a stepdown transformer to feed into the lappy's PSU/transformer which runs at 110v.
I tried three different plates in my room but it didn't solve the problem so I guess the problem is with lappy running on power cord anyways...
If you are anything like us, they will all be on the same ring, so you would only see a difference if one of the plates was defective?
You post has raised a side issue in my mind. I keep seeing adverts for these plug-in devices to turn your home power supply wiring into a home PC network.............I wonder if that would be affected by interference carried along the power cables?

Wow. I'm pretty surprised that was the cause of the issue. I would have thought that expensive equipment like laptops would filter those types of noise. But then again filters usually require larger amounts of capacitance which would take up lots of real estate in a laptop. Interesting though.
