DB-15 PC Input Vs. HDMI PC Input on my HDTV

[Soundmanred]

My HDTV (a full HD set -1080) will only allow 1024x768 when using the "PC Input" which is a DB-15 connector. It says it on a sidebar in the manual when I tried to figure out why it wasn't allowing my video card to pass 1920x1080 to the TV.
I am wondering if I use an HDMI cable instead of the DB-15 from my PC to the set if it will display 1920x1080.
Anybody know?
Under display properties I can go up to 1920x1080 and a few resolutions in between, but nothing over 1024x768 works as tested and stated by the manual.
I don't want to waste $$ on something (a HDMI cabl) ethat won't work any better than what I've got. My video card has an HDMI output and is powerful enough to run 1080.
It's an RCA 42" and it looks awesome for TV, gaming and video but I'm wondering if I can get more out of it (i.e. higher gaming resolutions, etc).

Yes it will

IF you connect the hdmi port from your computer to your tv and set it up correctly, you can indeed have 1080p signal going to the tv. Assuming your 42" RCA is 1080p native resolution. Check the native resolution out first, then set the resolution of the output to whatever that is.

Some TV's limit the max resolution of the VGA input. The OP obviously has one of those TV's.

No doubt the vga port tend to be limited. But I am more thinking maybe the 42" is not a 1080p at all. There have been quite a few sets that say 1080p input

It is a true 1080 set.
The high def channels look almost 3-D, it's awesome.
I watched House tonight and was blown away.
Not bad for an $800 42" 1080 TV...
TV Manual .PDF It lists the different kinds of inputs and what resolutions they can handle on page 13.
I know it will do 1080p with HDMI using Bluray, etc.
Just making sure about the PC input and that it was limited to just the DB-15 connection.
Anyone know why that is?

cost cutting. It could also be some sort of anal retentive studio request to combat piracy.

It works perfectly at 1920x1080 using DVI->HDMI adapter->HDMI cable to TV.
I have an Nvidia 8 series graphics card, so it took some research to get it scaled to my screen perfectly, but you almost have to expect that these days. (Sadly)
Thanks for your help guys!

there are dvi-hdmi cable available at monoprice.com but since you already have the adapter, just keep using it.

1920x1080 is not in the spec for VGA that is why i'm guessing its normally avoided
hdmi will work
