I am not sure where to post this, I am fighting for over a week trying to get a XP OS operational to use Glassware Audios tube amp design software and PSUD (the version for Macintosh is very basic and does not allow for circuit changes). I got a DB9 to HD15 adapter, then plugging the HD15 into a television (DVI to HDMI works fine).
I have no signal is coming into the television according to the television. I can hear the computer running through the start up, so would think there be something. I also tried both ports, the one near the top and the one near the bottom, no change.
The computer has not been used in years, was functioning just fine, though would storage cause the graphics card to fail? The storage unit got super hot over the summer.
The only other variable besides the television (used to be using a cathode ray tube monitor) is the new VGA cable.
Is the signal coming from DB9 too weak to supply a television?
Is there a way to check for signal from the computer?
Thanks in advance! 😀

There are many modes that are referred to as "VGA", all different resolutions and frequencies.
Did you mean you can get it all to work via DVI to HDMI? Why not use that?
Impossible to tell more without more details. What is the graphics card? What is the TV?

I switched to Macintosh in Spring of 2013 based on the lies from the professors they be better help if used Macintosh instead of Microsoft. Glad I made the switch, no regrets. Even when using Microsoft, didn't ever learn about cables, so after buying a few, two in the last week, I have learned a lot. DB9 is nine pins and was superseded by HD15 with 15 pins. The XP uses both and since not labeled, not sure which, though seem to recall using the upper port.There are many modes that are referred to as "VGA", all different resolutions and frequencies.
When Windows 8 came out, bought a Windows 7 HP desktop. Forget what happened to the monitor, long time ago started using a television as at the time couldn't afford a monitor and the television was dumped on me (used to belong to my maternal grandmother for the bedroom and sister in law left it at my house not seeing a television in the front room). I thought I do the same for the XP, however, this does not seem to work.Did you mean you can get it all to work via DVI to HDMI? Why not use that?
I don't know, how do I find out?What is the graphics card?
What is the TV?
As I said, that still did not get signal.I can clearly see a DB15HD on your graphics card. I think you may have been plugging the TV into your serial port, which is DB9 male.
So the top two (including the pink) are serial ports?
As I said, there are many modes, and not like modern interfaces where handshaking occurs.
Just basic troubleshooting, too lengthy to write out. Does the PC boot? Does it display properly to any other device you have? Have you tried changing display settings on PC and TV?

How does a human greeting have to do with computers?As I said, there are many modes, and not like modern interfaces where handshaking occurs.
So need to take it to a shop? I think it be better to replace the graphics card and see if that fixes it, would think be less money.Just basic troubleshooting, too lengthy to write out.
Sounds like it.Does the PC boot?
I have only tried the one television. If the signal generated by the old graphics cards is same as modern, then dig out my huge tele (I don't watch tele programs).Does it display properly to any other device you have?
Of course changed the tele input to VCA. Also tried both HDMI ports, also double checked the HDMI from the Windows 7 was also working, which it is, so know the HDMI ports on the tele are good.Have you tried changing display settings on PC and TV?
DB9 has not been video since CGA/EGA, decades ago. Also the gender is different.I got a DB9 to HD15 adapter
Here is what you have. TWO possible solutions.
The blue 15-pin female IS a VGA output. You need a VGA-VGA cable to go to your TV.
-OR-
The very strange many-hole connector is a DVI, the video between VGA and HDMI. A DVI-to-HDMI cable is under $10
Computers are already smarter than humans. Why shouldn't they greet each other? Use of the word "handshake" is just well-understood slang. People with no hands, or people afraid of germs, can bump elbows or wink and get the same social function.How does a human greeting have to do with computers?
A PC and a monitor(TV), when connected, will "discuss" what mode to be in. "Can you do 4000x2500?" "No" "How about 1920X1080?" "OK".
I tried DVI again, some progress made:
Once finished booting, get a green screen. Never seen this before!

I thought finally had it, download Glassware, go to the bathroom, and shut down on its own. Now fighting it again. Causing me to loath PCs even more, how asinine to design a OS that requires shutting down every time leave and then fighting to get the startup page (asinine having to push F8 over and over, versus a one keystroke, worse, having to hear that annoying high pitched beep over and over and over and over and over and over and over and over and over and over and over and over...).
Graphics card seems to have gone intermittent, works for part of the start up and then disconnects. Or is it the television?
How about a 44" "monitor"? 😆
Okay, it is the Element going out of its element. So, yay, another thing to research and take up hours: a monitor. At least it wasn't the graphics card, that take up even more time!
Now fighting with it reverting back to not finishing the start up, stuck showing a blank desktop with no toolbar. I run the computer in safe mode, though that doesn't allow installing programs, so that isn't going to work.

By the way, realized the smart thing be to sort out Windows XP, as no point having a monitor if not going to work. Found my notes from a few years ago, then looking at the options on the product page, see Philips 288E2E. Checking the reviews looks a better deal, don't need anything fancy.
