HDMI and DVI connections at the same time?

04-24-2005, 07:19 AM

Been reading these boards for the past few weeks. A wealth of information!

I just jumped on the HD bandwagon with a Samsung P4663W. I also bought a Samsung DVD Player (DVD-HD841) for the DVI output. The picture looks amazing on DVDs !

My question is: I only have one DVI input on the TV, but there is also an HDMI input. I would assume that when D* comes out to connect my new HD box (tomorrow!) they will want to use the DVI input on the TV, but I am using it for my DVD player. Can I use the HDMI input on the TV as well for one of these connections?

Many thanks !

DVI and HDMI are the same for video applications. HDMI provides and advantage over DVI because HDMI also includes an audio feed. Directv can use the HDMI connection if your receiver has an HDMI output. If you run into any problems go to the following address:

This distributor has all the adaptors and cables to make your connection of your DVD player and Directv receiver to maximize your digital and HD experience.

Let me know if this helps.

I'll keep my fingers crossed. Hope all goes well with the installation.

Well, they've come and gone. I was able to use the HDMI input, so all is well on that front.

I must say though, I was less than impressed with the HD channels. They look really pixelated, and not very "hi-defy." I've seen the same channels on my brothers TV (same as mine) through Comcast, and they were stellar. I'm hoping with the new bird going up that there will be less compression going on, and I might actually get a good picture.

Also, the installer told me that the ova antenna I was going to have them install is worthless in my area, and to go to RadioShack and get one at $300! I'm going to call D* and see if I can get waivers on the east coast feed for now (wish me luck on that one).

Thanks for the help,

Is your STB setup to output all formats as 720p?

You might want to try a few adjustments on your Sammy 4663 before you blame "everything" on D*. Granted, I believe that some HD channels are getting down-ressed by D*, and I have never been able to match the PQ I get from the locals on antenna.

If you are not afraid to go into the Service Menu of your set, adjust the GAMMA down to 0. This has worked for many people in removing much, if not all, of the pixelation, especially in dark scenes.

What receiver did you end up with? Does it have the ability to upconvert all signals to 720p? If so, set it for 720p, which is the native resolution of your set. Then set your TV's picture size to "Expand". This will give you 1-to-1 pixel matching. Set the Contrast to 80, Brightness to 40, Color to 40, Sharpness to 0. Standard Picture Mode with Normal Color Tone. Turn off DNIe and DNR.

These settings are starting points. I have had tremendous satisfaction with these settings. The default settings are to make the set look good on the showroom floor, and have nothing to do with the set looking good in your living room. YMMV

Thanks for all the tips here. That's why this is such a great forum. I will give them a shot tonight. I was really hoping it was something I could fine tune.

I did pick up a cheap (~$30) Terk antenna last night and was able to get ABC, CBS and NBC in all their HD glory. Good start there.

I ended up with the HR10-250 receiver.

Thanks again. I'll report back tomorrow with my findings.

Ok, I tried some of the above mentioned tips. I made sure the receiver is set for 720p, and made sure the TVs setting was still its native resolution. I went to standard picture mode, normal color tone and DNIe and DNR off. Couldn't find the Gamma adjustment, so didn't modify that. I think the picture looks better already though, from what I could tell in a quick test last night.

Now if I could just get FOX in HD !!!!! :)

Thanks again everyone. This HD stuff is fun!

A better start would use anything but a Terk antenna...

Out of the "big 4" stations, I'm receiving 3 with excellent quality from 40+ miles away. They are all in the same tower cluster, and the one station I cannot receive is broadcasting at 1/10th the power of the other 3.

Am I *really* going to be better off returning the Terk? I have heard bad things about the Terk, but for ~$30 I get some really good reception considering it's a cheap indoor antenna sitting in front of a wall and next to my TV. I have no desire to purchase an outdoor antenna at this time, or an expensive indoor antenna, since I'm in one of the 12 markets that D* will start delivering HD locals too this summer/fall.

If you're getting everything that's at full power & it's a temp deal anyway then forget it... the low power station must come up to full power soon or they will have their licensed coverage area reduced... by July 1.

Update on my waiver requests. I got these back in about a week. I'm in the Boston area, and the towers about about 40 miles away:

ABC: Denied
CBS: Denied
NBC: Accepted (!)
FOX: Pending

The one I really want is FOX so my fingers are still crossed.

I have a Terk TV55, and it works very well...I'm 35-40 miles from most of the towers in my area. I can set it on my roof and bring it inside when I'm done, or I can just leave it out there if I'm lazy. It's been very, very difficult for me to receive all but one or two of the local stations with the three other antennas (antennae?) that I've had.
