You should get the following screen.
Powerstrip guide.
First try a default Display Profile:
Notice above how the Horizontal and Vertical "+" and "-" buttons are depressed or not depressed. The above setting is for negative sync.
Try a new display setting:
Select the "Advanced timing options" button.
480p and 960i should use a Horizontal Scan Rate of 31.5 Khz.
To see if your display accepts the resolution, click the "Advanced Timing options" button.
A CRT monitor (regular old, "picture tube" type monitor) of pretty good size is recommended for troubleshooting and setup. The bigger and badder the display is, the better it will be for this - especially if you will be shooting for higher resolutions or "interlaced" resolutions. Monitors that support a wide variety of resolutions and refresh rates are best.
Overscan - The desktop or other video input is too wide or tall for the display, and is "cropped", or sort of, "past the top/bottom/sides of the display".
Please read the excellent guide at Keohi HDTV.
Building an HTPC-2 Powerstrip is indeed "the killer app" of the HTPC world. It is possibly the most important program today in the "convergence" market between computers (PC only unfortunately!) and the high definition television (HDTV) or Projector marketplace. With it you can craft a custom resolution and sync timings to enable the best possible display of your computer Desktop, DVD's and other video sources from an HTPC to an HDTV or Projector.To use Powerstrip, you must have a video card that supports custom resolutions. Some of the cards that support custom resolutions are the ATI Radeon series, Matrox G-series, Parhelia, NVidia or 3dfx graphics cards. Some of the cards that do not support custom resolutions are the S3, SiS, Trident, Intel, ATI Rage and Rage128 cards. This guide is only meant to augment the great wealth of information on this program that is already available. It is by no means complete and certainly not guaranteed to be 100% accurate. The idea was to try and create a "Powerstrip for the powerstrip impaired" type of guide, with pictures to make it a little easier. This is truely easier said than done. Hopefully this guide will be helpful. Any suggestions will certainly be appreciated. Please email the WebMaster with suggestions and corrections. Below are the the best "official" and "sort of" official guides.
Set the Horizontal scan rate to 33.75 and hit your "Tab" key (540p/1080i).
Setting the proper scan rates - Important!
Click the "Add new Resolution" button.
Your computer will start up again into the original resolution you were using, not the newly added resolutions, so don't get ready to panic yet. Wait 'til later.
You will get the following popup window.

the following screen usually appears the first time you use a custom resolution.
Click the "OK" button.
Select the "Custom Resolutions" button.
Select "Options. " -> "Preferences. "
You can either click "restart" now or continue and add more resolutions by clicking the "continue" button. When finished adding resolutions you want to try using, click "Restart".
Tweaking Section.
OK, then, assuming you get this working. We are not going to "tweak" the settings yet. For instructions on doing this see the "tweak" section. The thrill of.
Click the "Selected" button to choose your newly set resolution.
640x480p will certainly wear off quickly. Not enough room! Next you may want to experiment with more of the "Predefined" resolutions, if you think they should be compatible with your display. 848x480 is a good place to start for people with widescreen 16:9 displays that accept 540p/1080i vertical resolutions. Use the same techniques you used above, especially the part about stopping and relaxing when things aren't working.
Set the "Total lines" in the "Vertical geometry" section to "563"(540p/1080i)
We will use 896 for Horizontal and 504 for vertical resolutions.
***Note*** If you now have a problem with the display, again, DO Nothing for fifteen seconds and the display should change back to the previous settings and start working again. If not, try these key combinations:
OK, after you have Powerstrip installed and have a setting that actually works, what problems might you expect then?
Select the "Custom Resolutions" button.
3) Patience and "Nerves of Steel"
Check to make sure everything looks ok. For instance, if using the Key Digital KD-VTCA2 Transcoder, make sure the sync Polarity is set the same in Powerstrip as it is set on the.
8x112=896. Keep multiplying 8 times some other number to find resolutions to try. For a 16:9 display, with an 896 horizontal resolution, you would take 896, multiply by 9 and then divide by 16. You get 504.
Overscan/Underscan/ Screen Positioning:
The following screen will appear.
Click the "Advanced timings options.." button.
Position - The screen is not centered!
Install Powerstrip, restart.
Use the "Resolution" Slider to find your Resolution. In this case it should be "640x480 pixels", or the resolution you are trying to use.
We are now going to create a new Display Profile. We will be using 1080i/540p based timings to match our RPTV HDTV display which does not support 720p. [note] If your display supports 720p (you're sure?) we highly recommend you use 720p (around 45 kHz Horizontal). Make very sure your set REALLY supports 720p, some will convert 720p to 480p or 1080i, in which case it will not accept the necessary Horizontal scan rate and won't work!
Fudging these numbers a bit is possible to a small degree, depending on the display.
Click the Powerstrip tray icon and select "Display Profiles" -> "Configure".
If you can view the display, you should get the following popup window.
Powerstrip is very powerful, but also quite capable of causing your computer and display to stop "communicating" properly, this could cause the display to start rolling, doubling or generally freaking out. It is important that you don't freak out as well. It is recommended that you know how to start up your computer in "Safe" mode and "VGA" mode (safe mode for Win9x users) , uninstall and reinstall drivers and get around in "Device Manager" if you wish to use this software. Legal disclaimer thingy: Use at your own risk! We are not aware of anyone causing damage to their display devices using this software, or any of the methods used in this guide, but if any damage should occur, we are certainly not responsible. Please sue someone else.
The time should count down from 15 seconds and reset your display back to normal if you don't click the "Yes" button. If you're able to see things somewhat properly, ready to start adjusting things, click "Yes". [Note] If the display is not centered, too tall or too narrow, you will need to tweak things, so you'll need to click "Yes" to do that. Don't expect things to be perfect, just "useable".
If you have a Problem: If things are bad, reattach the CRT and check your settings. A monitor will usually be far more forgiving than your HDTV, so you need to be more detail oriented when trying to make it work. Make sure the settings look like they should work with your transcoder if you are using one. Is the polarity correct? Resolution compatible and properly set on the transcoder or projector?
"ALT-R" key combination - resets display , continue.
Connect the CRT!
After restarting:
Much depends on your display.
Your horizontal resolution for most video cards should be divisible by 8. Good resolutions to use are therefore 848, 856, 864, 872, 880, etc. For those mathematically challenged,
If you get an unusable display, wait 15 seconds or hit the key and you should go back to your regular settings.
What you need to know Beforehand:
Custom Resolutions:
If this does not work, try a different "Predefined" resolution. If things don't work only when connecting the HDTV or Projector (PJ) , recheck your transcoder settings and/or.
With the resolutions set to "Predefined" (default) rather than "User defined" Select 640x480p, or another resolution that is compatible with your HDTV.
You can either click "restart" now or continue and add more resolutions by clicking the "continue" button. When finished adding resolutions you may want to try, click.
Use the same technique for 4:3 displays. You will probably want to shoot for smaller horizontal resolutions than a widescreen display.
720p and 1440i should use a Horizontal Scan Rate of 45.0 Khz.
If things are working fine after restarting, you are ready to try the new resolution.
will need to tweak it for overscan, underscan, screen sizing and screen positioning. Powerstrip provides a variety of buttons for adjusting these parameters, or you can use "manual settings" by typing them in. You can adjust settings for such strange things as "front porch", "rear porch", "polarity" and more. Powerstrip does make this a bit more user freindly than is sometimes good for an HTPC user, since you will be tempted to "tweak" things faster than you should. Remember - make slight adjustments and save them. Then make more slight adjustments and save them. You will possibly need to do a lot of "Window Resizing" to tame Windows obsession with opening things in windows that will not fit on the display. Most modern Windows versions will want to open windows that will not fit your resolution, especially if you have an RPTV display that cannot do 720p. In many cases you can resize all of the "important" windows to display properly. Some windows, such as the "Advanced Display Properties" window may very well be too tall for the screen, and you will not be able to resize them. For these windows, either unplug the "intended final display monitor" (your HDTV) and switch to your CRT monitor, or use the "lucky tab" method - use the key until you think you have the "OK" button selected and the press . Some popular programs will not work without a resolution of at least 800x600. These programs will not work if you can't get a resolution that high. For many RPTV users you'll need to switch to your CRT or another monitor that supports the resolution if you wish to use these programs. Either that or get a HDTV, plasma screen, Projector or other display which can handle at least 800x600.
"escape" key - reset and close display.
Powerstrip Gu >
"backspace" key - undo, cancels last adjustment.
"Click" the Little Powerstrip icon.
Change to the new resolution, in this case "896x504".
Assuming you get this working. on to tweaking.
[note] You should usually not change the sync settings using your HDTV, use the CRT for that.
Make sure "Polarity" settings are the same as what you found to work previously. Keeping the "Aspect Ratio" on "Auto" is usually a good idea, but you can change this if you need to.
Dip Switch on the Transcoder.
2) For Those Tricky Analog Signal Settings - Setup/emergency "CRT" Monitor (in addition to your main HDTV Display)
Terms:
4) You need to have an HDTV or Projector capable of resolutions over 640x480i (standard NTSC Television) in general to get the most from the software.
Vertical - tall, short - up down.
Click the Powerstrip tray icon and select "Display Profiles" -> "Configure".
Click the "Add New Resolution" button.
Underscan - The visual content is too short, or too narrow to fit the display.
Click the Powerstrip tray icon and select "Display Profiles" -> "Configure".
[note] There are a number of old "Workstation" monitors out there on the used market which are "fixed frequency", these will not work for this. [note2] You cannot create resolutions which have a greater resolution than what your Displays driver allows. If Windows believes your monitor is only capable of 1284x1024, these are the maximum horizontal and vertical resolutions windows will allow you to use. The "workaround" is to change your Display Driver in "Device Manager". An often used display driver for this is the Sony GDM-W900, since it will take a very wide range of resolutions and refresh rates. While it's true you can fool windows into thinking your monitor can handle more than it should, remember, you can't fool your monitor. If it's not a GDM-W900, or something similar, it will not display any crazy thing you send at it.
At the top left, find the checkbox for "Auto load with Windows", and check it.
If you get upset. STOP! Try again when you feel calm and relaxed. Browse the aforementioned forums for clues.
The "Custom Resolution Guide for HDTV-HTPC-POWERSTRIP-RADEON" thread on AVS Forums - Great in-depth information too!
Set the Horizontal refresh rate to 34 Hz.
First of all, you may (especially with an RPTV) have to compromise between resolutions and amounts of overscan and/or underscan on both horizontal and vertical resolutions.
540p and 1080i should use a Horizontal Scan Rate of 33.75 Khz.
Click the Powerstrip tray icon and select "Display Profiles" -> "Configure".
Getting Started.
Making Adjustments:
["horizontal-resolution" x 3 / 4 = "vertical-resolution"]
["horizontal-resolution" x 9 / 16 = "vertical-resolution"]
Change the resolution button to "User defined" rather than the "Predefined" (default).
TESTING WITH YOUR HDTV: Now you are ready to plug in your HDTV. If you get an unusable display, plug your CRT back in and relax a bit. If you get a display that doesn't roll and looks relatively ok, you are ready to start "Tweaking" the display.
Display devices supported resolutions. Maybe it does not support 640x480p? Scan rate not correct? Try again, repeat as necessary.
The Official Entech PowerstripForum - Great in-depth information.
you should get this screen.
Remember not to get too ambitious with resolutions at first.
Select the "Advanced timing options" button.
Forewarned is forearmed, so before we even get started there are things you need to know.
You are going to have to deal with screen positioning, size and "overscan" or "underscan" issues. This is normal. For each resolution you set on an HDTV, you.
Big, old Sony Trinitrons are often favored. You can certainly use a smaller monitor if your intended resolutions will work on it. You just have to be more careful.
