Now, I want to take a big step and do what the owners manual says not to do (for what reason, can anyone tell me?): Hook up HTPC
Basically, my PC will have an HDTV Wonder and Radeon 9600XT. I have purchased a DVI/HDMI cable. I'm not going to blow up the Toshi by plugging the radeon into it am I?
I have heard some problems about compatibility between a PC output and a TV/monitor input having to do with scaling problems, sync problems, etc. I am anticipating that I will need to tweak the outgoing video signal if this is going to work at all.
So can anyone give me any advice?
I hooked my htpc on the first day. On my (nvidia) card the DVI output
was not active if the analog VGA was connected but this depends on the
mode the drivers expect you to use the DVI port (clone or dual monitor).
I found that at boot the Toshiba will sink to the 640x480 initial resolution
but the overscan will be significant. My first step was to boot on a standard
analog vga monitor and set it for 1280x720, power down pull out the vga
and plug in the DVI and reboot. I expect you will at least see desktop. You
will have trouble seeing the task bar (because of overscan) and the problem
with powerstrip is that once it's installed it is activated from the system tray.
You will have to avtivate it w/o seeing the cursor. The latest version of
powerstrip has a lot of preset resolutions for DLP and LCOS monitors. I
would try these first. Powerstrip also allows you to tweak the actual
timing parameters interavtively. Some of these will cause you to loose
picture. learn the powerstrip hot-key that restores the default frequencies.
By playing with the front porch/back-porch setting I was able to get most
of the taskbar displayed. Powerstrip will remember this and the next time
you boot you will start from there.
This is all I have learned from a single short session. I encourage you to go
ahead and experiment. The more of us working the sooner the solution. I will
(and encourage you) to search these forms for information on how others
have achieved 1-1 pixel mapping. You will know you are there when you
see razor sharp non-grainy characters. The (non 1to1) effect looks exactly the
same as setting your laptop resolution to a resolution different from it's
native resolution. Please share your results.
