Philips 26PF9956 powerstrip resolution help!

Hi,
I have been using my Philips 26PF9956 as a computer monitor for the last year and with the aid of powerstrip I was able to get a resolution of 1280 x 768. Today my powerstrip licence ran out and although I renewed it I can't seem to use the custom resolution that I had previously (1280 x 768). When I select the preferred resolution I get a very blurry screen as shown in the pic. Have I got something wrong in powerstrip? I have tried changing a few settings within it but it hasn't helped. Any help on this matter would be much appreciated.

Do you have a "safe" resolution that works (such as 768x1024)?

If so you can assign a hotkey to this resolution, and that will help when you are playing with the settings (within options).

Have you checked to see if the refresh rate is custom, "Standard discrete timings" or "Windows Default" (60Hz or custom like 59.98456Hz etc)?

Another problem could be if PS has inadvertantly overclocked your graphics card, have a check of the performance profile.

When I was trying to get a stable resolution I had an excel file, where I recorded each attempt, front porch, sync, etc...

Luckily I have 2 PC's, and recently swapped graphics cards, my 9500pro with latest Ati drivers works natively over DVI without PS, whereas my 9800se needed PS over DVI, but is fine natively via VGA with Ati drivers.

Yes I have assigned a safe resolution to a hotkey, but I'm still not getting anywhere. My graphics card is a NVIDIA GeForce 4 MX440 and I am using the DVI connection. I have also noticed that the resolution 1280 x 960 also works but the picture isn't extremely clear as it is not at the native resolution of the screen. Would it help to get a better graphics card for my pc and avoid using powerstrip? If so have you any suggestions of a good graphics card to get the desired 1280 x 768 res?

Unfortunately the DVI native capability seems fairly random. My 9800se requires PS but my older 9500pro does not.

If you do get a newer card, you could go for a passively cooled one, as the 40-60mm fans typically used on graphic cards are very loud. I have retro fitted a dual heat pipe passive cooler to my 9800se but these are £20-30, my next gfx will be passive out of the box.

Another issue could be AGP obsolescence, if you buy a new expensive gfx now, it may not fit a newer machine if you upgrade (may only have PCI-E).

Have you tried d/l the latest nvidia drivers?

Have you looked through the ps forums for any other Philips (opps) user's settings?


For what its worth, here are the setting I tried on my 1280x768 Medion LCD:-

Thanks for that, I have downloaded the latest Nvidia drivers and that gave me a few more resolutions to choose from but when I select 1280 x 768 I still get the same blurry screen. I have managed to get 1264 x 768 to work but the onscreen text seem to be slightly off obviously due to this res not matching the native one. It's unusual because all of the other available resolutions work except for the native one! I have been looking at ATI Radeon 9550 256mb AGP DDR DVI Graphics Card, do you think this would be a better solution?

I did not recommend a 9500pro as I only know it works on my Medion 32" lcd. I would hate for you to buy one, and for it not to work without Powerstrip on your Philips (oops).

Mines a Sapphire:-

Personally I would not buy a re-fub graphics card, even with a guarantee.

Your existing graphics card worked quite happily for 12months, its a case of biting your lip and being patient trying to re-discover the settings.

I've tried messing around with powerstrip for hours and I don't think I'm getting anywhere. I think my next option is to get a new graphics card, and possibly avoid powerstrip. My current graphics card is 128mb, would it help to get a more powerful (256mb) graphics card? Also reading around on the forums ati is preferred to my current make of Nvidia, for this purpose, would you agree with this?

A 256MB gfx is not neccessarily faster than a 128MB, as the GPU clock speed and RAM speed have a massive affect.

My ati 9500pro is 128MB, but works fine. You can check out tomshardwareguide for good gfx benchmark comparisons.

Ati seem to be used by many HTPC users, but there are many Nvidia 6600GT posts on the Entertainment computer forum. Have a browse before splashing the cash.

It may be worth posting there, as they are very knowledgeable (a lot more than me!!).

Its always a balance between not overspending on one component of your PC, and at the same time trying to future proof it. Your orginal gfx was fairly low spec (relatively), what is the rest of your system?

My desktop is a couple of years old now but I had it custom built from new so the graphics card was probably just the cheapest one to hand at the time. The desktop itself is a AMD Athlon XP2600+ with 512MB ram. Since new I have only put in an LG dvd burner, but everything else is still the same so it's probably about time for a new graphics card. Thanks for your advice, I will post on the HTPC forums and hopefully get a result
