Default PC to HDTV with 1080p

With the new generation of LCD HDTV's coming out. Mostly all of them are outputting a true 1080p (1920x1080) resolution. How will this effect thoughs who want to use their HDTV as a PC monitor?

With the higher resolutions (1080p), can we finally play our games with a crisp, clear, high res picture with a high end video card (exp. Geforce 7950)?

Will the over scan issue be resolved with the new 1080p sets? My ATI X800 with ATI Catalyst drivers has HDTV 1080p output support. Is anyone familar with using the ATI driver for HDTV? How well does it work?

Also, I have read a lot about DVI not supporting a PC's DVI signal. Is this true? Will it be a waste of money if I purchase a DVI to a HDMI cable? Samsung specifically says they do not support it on their sets (look under their FAQ's section)

Samsung and other sets come out with a 15-pin D-Sub VGA input, but with any high end video card today they only support DVI-D connections. No VGA, If I use the adaptor (DVI to VGA) that comes with most video cards and plug that into the VGA slot of my HDTV (which Samsung recommends) how will my picture be?

I recall when I first bought my PC LCD monitor I used the analog connection (DVI from video card to VGA) input on my monitor. I noticed the font was horrible and the image was disstorted. It wasn't until I plugged a DVI cable into the DVI slot of my monitor that I had a crisp, clear picture. Will this be the case with an LCD HDTV if I plug it into the VGA connection (from the DVI-D on my video card) of the TV set?

The set I am looking at is the new Samsung LN-S4095D 40'' LCD but I don't want to buy it unless I know it will work with a crisp, clean picture for my browsing and games.

Thanks,
Jamie

I've got a Samsung 5088 (1080P) and the PC screen looks fine to me. Fills the entire screen. Unfortunately, the laptop I'm using only goes to 1024 x 768 (POS) so I can't test at higher resolutions at the moment.

If you have access to a decent laptop bring one in to the store and have them hook it up.

Just hooked my PC up to the 5088 (required a 50 foot VGA cable...lol......to my ATI X800. Seems to work fine. However, the 1080 rez stretches the screen way out of whack. I didn't mess with it too much but I'm typing this using 720p rez. I can read every word....colors are nice and bright, etc. I've heard about a so-called "Game Mode" and I have it on the 23" Samsung LCD but can't find it on this DLPs menu.

There's no overscan that I can see.

I use the little adapter (DVI-VGA) with the X800.....looks fine to me.

I know you said LCD but the menu system, settings, etc are very similar on this one and my LCD. The only issue I had with the 23 inch was lying to it about the rez so it'd display properly. If you get a 1080p display you shouldn't have that issue I wouldn't think.

If you don't have a laptop have the sales people hook one up. If they won't do it walk out the door.

Default the laptop res does interfere!

having a Vaio 1920x1200 I can report that in hdmi mode the screen il of course bigger than the 1920x1080 nominal resolution : you have to use the slider on the laptop to choose which section (top or bottom) you want to keep. This does not come into play with dvds. A very minor hitch one would admit! I'm not that certain that you can easily adapt an hdmi laptop's resolution that is not 16x9 natively

That's because your PC's resolution is much lower than the TV's native resolution.

Try using one of the various software tweak utilties that allow you to set the video card specifically to 1920x1080.

Default PC to a Westinghouse 42" Monitor

I used the VGA connector from an ATI 1300 512 video card to a Westinghouse 42" monitor and set up as dual. ( My standard PC monitor is a Westinghouse Widescreen 17) The 42 inch looks outstanding, running at 1920x1080. I tried the game "Oblivion" and it looked great but I realized that I'll need a better PC to get good performance. At 1920x1080 resolution, it slows it down some although it is still playable. The system has a 2.4 Ghz processor. Using it for web browsing, viewing/editing photos and other applications it looks and performs great.

Default tweaking unstable!

I did try to configure a second screen but the laptop or the projector didn't like it : in hdmi mode, they're supposed to engage in a kind of dialogue, if I get it right, and the projector almost always reverted to dvi as common ground - with the consequence that it would be 4/3 (1024x768). The only way my system would state 1080i was when the computer was set to 1 screen mode, the second being a copy of the first, with those 180 extra pixels being left out of the display. To be noted too is the fact that the computer has to be set to 1080i BEFORE the DVI/HDCP Z2 projector is turned on, or the choice of output offered under FN+F7 would be DVI+ Vaio, not HDMI + Vaio. Now I get HDMI at the click of the mouse, but the handbook certainly didn't help!
It's past compare to be able to enjoy viewing the laptop picture in hdmi, even small print comes out clear (not loud!) on the 2 meters wide screen. Any 16x9 material is perfect as the extra pixels are not needed ... and you don't have to fiddle for your mouse pointer from one screen to the next!
Note : when playing dvds you only get the picture on the projector screen, not the laptop.Any other footage plays on both -digital terrestrial tv included.

My Sceptre is performing very well check out the fps files are of .ts but look at the poor cpu utilization. VLC will play the same file at 0 to 2% it almost plays the file at 99.8 % hardware accelerated. Res is native 1920x1080p/60 MHz

So, you're saying if I set the PC at 1920 x 1080 the screen will be way too big unless I use Powerstrip or similar program?

First of all the only 1080p sources currently available are Blue-Ray or HD-DVD. The cable/DirectTV/Dish networks just upgraded to 720p and 1080i at considerable expense. I seriously doubt that a couple of years later they are going to ditch that $90,000 Sony 1080i camera to purchase a $110,000 1080p camera.
