When playing with Powerstrip’s Display Profiles, I was able to trace the exact key that makes all adjustments—it was a Key #3. The resolution for other 4 Keys stayed the same, no matter what. Your case might be different. Try and see what happens. However, be very careful! It’s registry.

The only sure way to find out which key is performing resolution adjustments is to use a demo version of Powerstrip and see what happens to all keys.

In my case, it is Key #3. Your case would be different, I assume.

a little off topic but say I get a plasma screen and the max res is 800x480

would that look like ****?

Plasma screen? As in, home theater?

yup... a lot of em have either the standard vga input or dvi

Ahh. I see where you are going with this...

I can't imagine 800x400 looking too bad. Depending on the size of your screen, it might look a little large, but thats all.

Interesting idea. Good luck with it.

Figured i'd dig up old threads instead of starting new ones (yes i use search! ).

Thought i'd share my two pence after having a major headache trying to get anywhere near the native resolution of my lcd (DSCUSTOMS GA700YYV (TSV) which is 800x400 same as Xenarc's screen. I'm running a GeForce DDR (original 32mb) and it has quite a wide varity of res's i was using 1280x720 (1.77 ratio) for a while but it really was too small for a little 7'er even with font size set to 150% and large icons! so i dug a little deeper and round 848x400 which was just horrid not sure if it was the controller on the card but it just seemed to be overscanning so it was streacted vertically and squashed horizontally .

I eventually settled on 720-480 (1.5 ratio) which seems to be ideal, videos seem to be scalled prorportiantly and i'm happy

So lets take a look at the resoltions which I can run:

Code:

                      Res        Ratio
Native Resolution     800x400:   2
Standard XP           800x600:   1.33
Res #1                1280x720:  1.77
Res #2                848x400:   2.12
Res #3                720x480:   1.5

I think #3 is my best bet! if anybody has any comments please let me know

There are two ways to do it. Hacking a registry or using Powerstrip 3.29 build Build 342 (Full Version). Second choice is safest and it works.

Hacking registry:

Go to: HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr ol\VIDEO\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000

On the bottom, you will see:
DefaultSettings.XResolution 0x00000320 (800)
DefaultSettings.YResolution 0x00000258 (600)

Double click values, input any decimal value you want, exit, and reboot the machine. Win XP will display that bubbly thing with a warning saying that you might have a problem with resolution settings. Just ignore it.

I never used it but people say it works. Just make sure you back up your precious registry!

Sorry, I have to call bull****, you can change the resolution to below 800x 600 by going to

display properties-->advanced-->adapter-->list all modes

Dave,

800x600 is in ratio 4:3 which is the most common ration for display´s, television, monitors

Then came the widescreen format 'cause the screens in movie theathers had 16:9 aspect ratio... (which is more normal to the human eye to look at...)

Then came the widescreen televisions which also have a 16:9 ratio, 'cause people wanted to be able to look at the same movie with the same aspect ratio at home.

800x480 is just the 'resolution' for 16:9 where 800x600 is for 4:3
This is done because 800x600 on a widescreen looks, well, very wide and short...

800/16=50
50x9=450 which is almost the 480 in the resolution... (don´t ask me why the have not set the resolution at 800x450, i don´t know)

so, less pixels vertically to compensate for the wider screen.

I run 800x480 on my widescreen television, and with a little tweaking like colors, and flicker-filter it looks very nice..
Almost the same as running 800x600 on a normal crt. (better as when i run 800x600 on the widescreen which looks stretched horizontaly)

Greetz,

Hmm, I'm having trouble setting my new screen to a widescreen res. PowerStrip doesn't work -- custom resolution button is always disabled.

I looked at the reg keys mentioned, there were none that matched exactly letter for letter the posts, but several of them did appear to contain X and Y resolutions. I tried setting different resolutions and checking the reg keys, but they always said 800x600, even when I was in 640x480. I tried manually changing a couple and rebooting but it had no effect.

Any suggestions?

Right now I'm running 800x600 and it's not too bad, but things are stretched a tad wide.

Oh yeah, my video is the onboard video provided by the Intel 815e chipset, using the latest Intel drivers.
