connecting screen without onboard vga options

spikey1973 · Jul 12, 2014

Hey,

i've got a very, very blond question. but i'm gonna ask it anyway as i might just be missing some important detail.

I've recently bought a MSI-P55-CD53 mainboard is shipping over), and have a i3 550 CPU waiting for it. but only tonight i figured out that my (all P55 mainboards?) mainboard doesn't have on board VGA.

bought this board to be able to DOWN clock this board on all possible parts. as i use it as an audio system and it will be uncooled doing basically nothing, bit of a waist to use a board like this for that in my heart ok, but the sound that will be coming out will be well worth it.

one of the parts that i need to downgrade is the onboard vga, which i don't have.
but i read in multiple places stuff like this.

"The MSI P55-CD53 does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card" so far nothing strange but than this.
"OR a processor that has a GPU on the same die, such as AMD APU processors." which according to many. my i3 550 graphics has got.

now is my simple question. how do i physically connect a screen to my mainboard with a GPU in the CPU, as that still doesn't give me a port to put a vga / dmhi cable in.

(i have a basic VGA-card around, but an internal VGA card is supposed to be bad for the sound so if there is ANY way around that i'd rather not

hoping for any answer that does not involve internal VGA cards, I great you all

I think I understand what you're concerned about, but your terminology and assumptions are a little off. What you're calling a VGA card is normally referred to as a graphics processing unit or GPU, sometimes called graphics card or video card. The "onboard" graphics is the integrated graphics processor (IGP) is a feature of the central processing unit (CPU, processor, processing chip, etc). Most, but not all, CPUs include an integrated graphics processor. An APU, or accelerated processing unit, is similar but actually contains a discrete, or separate, GPU built into it. What you've got, with your Intel CPU, is IGP - it's not an APU.

When MSI says your motherboard, or mobo for short, will not support onboard graphics, they're saying that it won't recognize or transmit the graphics signals coming from the CPU that you have. To get graphics, you will need an actual APU or install a discrete GPU. None of these (IGP, GPU, APU) are producing your audio signal other than as a pass-through if you use an HDMI connection. VGA is a standard of graphics signal transmission (through the VGA cable) to your monitor, but is graphics-only, no sound.

What you are concerned about is the audio signal. You get that either from the built-in audio component of your mobo or from a separately installed sound card that plugs into the mobo. Historically, the audio produced by mobo audio was pretty crappy, not so much anymore - many mid-grade and high-end boards produce excellent sound quality (assuming you have quality speakers to match).

Bottom line, with your setup, is that if you want a graphics signal (i.e. visuals on your monitor) you'll need to add a GPU, as your mobo will not take the signal from your CPU's integrated graphics. If you want sound, you can get it from your mobo (built in), or if its quality isn't high enough for your needs, you'll need to get a sound card and install it on your mobo. Depending on the quality, they range in price from @ $20 to over $200.

Thank you for your information,

indeed you are right, my terminology is a bit of... but simply speaking i allready understood what you told me, but just used the wrong terms. Problem I have that I have this IGP instead of a APU which leads me to install a physical extra card for this GPU, something i need to prevent for all costs.

I do understand that modern onboard soundcards are of good quality, but still there is an interference from the central part of the mobo to the audio part. no matter how good the audio part is (which never reaches really good analog quality) , which is also something i want to prevent.So the construct that i need is an onboard vga, with its functionalty striped down to its bare minimum to prevent interference on the central part of the mobo and decrease it's power consumption. With an external soundcard, DAC(s), AMP combination, which i have available.

this is not possible (was afraid of that, just needed a confirmation) as i need this GPU, which i don't have onboard. therefore i will ship this mobo back and change it for a mobo that will supply me with the right functionality for this project.

thanks for your reply. it helped me a lot!

kind greatings

I hear you - unfortunately, finding a new board compatible with that chip (LGA1156) at a decent price might be challenging. Here are two, but they're not cheap:

You could look at replacing the board and the chip with something more mainstream that utilizes the LGA1150 or LGA1155 chipset and supports IGP, so you can avoid the need for a discrete GPU. You could pick up a board and a chip that combined cost less than either of the mobos above, especially if you're looking for something really spartan that's mainly going to be the graphic "front-man" for an external sound system.
