PC -> HDTV

Ok, so i'm having some resolution issues hooking my PC up to my 37" Sharp Aquos 720p LCD.

1. I'm trying to use VGA, and 1024x768 looks correct(text looks great), but stretched. I've tried using 1280x720(unsupported) and 1360/1366x768 which should be the monitor's native res, but the text looks terrible, like when you have the resolution set to anything but hte native res on a LCD monitor.

2. Using component i can get 1280x720 to show up as 720p by the tv, but in windows it is all screwed up(not everything fits on the screen, you have to "scroll" to view everything).

3. Would the best thing be to just get a DVI->HDMI converter? Or would i still have the same issues here?

    2) What do you mean by 'in windows'? The screen on the PC, while hooked up to the TV? Or the display on the TV, which is displaying Windows at the time?

    Have you cycled through the options on the TV (ie. 16:9, widescreen, whatever else the menu has) while outputting 1360x720 from the pc?

    The TV is the only thing hooked up the PC atm. I mean windows displaying on the TV.

    Alright just tried that, it was set to "stretch" by default. I tried setting it to "dot-to-dot" and it seems it forces everything to a 4:3 ratio that way, which makes no freaking sense. It seems like it pulling everything out of VGA in at 1024x768, no matter what res i set the PC too. So setting it to 1366x768 is really downsizing it to 1024x768 and then stretching it to fit. Arghhhhhhhhh

    I'm using XP MCE if that makes any difference.

    what brand display adapter are you using? my nvida on my laptop has a tv setting to adapt to this sorta thing, but my ati on my desktop doesn't and it blows donkey shlong to try and make it look halfway descent... even with catalyst installed.

    I'm using a geforce 6600GT, latest invidia drivers etc. Could you take a screenshot of that feature?

    I didn't read much into it but have you tried PowerStrip?

    This might help because I was confused by the product page: Powerstrip Guide for the powerstrip impaired

    I don't know if this will help: since HDMI and DVI are the same signal, just different plugs, try out a HDMI to DVI cable

    I have my 9800gt going cloned off my samsung 22" lcd monitor to my 32" sharp aquos 720p

    I'm using a DVI cable to the monitor and a DVI-->HDMI adapter and an HDMI cable.

    the TV is currently plugged into port 1 making it the primary display. Some interesting facts:

    As primary display, the TV can do any resolution (including 1620x1080 native res of my monitor) at 60hz... but on port 2 it won't do 60 hz, it only does 30hz interlaced at that res.

    For video playback I have MPC automatically switching res to 720p (1280x720)when I switch to fullscreen mode.

    For some reason I get weird refresh tearing and the TV losing sync and dropping frames every now and then when the TV is not primary display on port1.

    Also my problems seem to compound with newer versions of the driver, I'm on 181.xx or something like that.

    And of course to piss me off especially after I bought the 22" monitor to specifically clone, the stupid monitor won't support true 720p on DVI... it overscans for some reason and the driver won't let me scale it to fit the screen.

    I'm not sure if this info is useful to you since you have a previous generation video card compared to mine.

    The TV will not support oldschool VGA cable in resolutions over 1024x768, you have to use component or HDMI/DVI to get 16:9 ratios.

    Ok thanks dude, that is priceless info. Ordered HDMI cable and will stop messing with it until it gets here.

    I just sent ya a PM with those settings I mentioned earlier. You probably would be better off with using the HDMI adapter anyway... hardware tech is teh most ugh of ugh to get around imo... just too damn frustraiting.

    Overscan?

    A tv is only ever guaranteed to show the inner 80% of the picture.

    HDTV has very little cutoff, if any... the safe area was more for tube tvs... some of them were absolutely terrible

    That's actually a common misconception.

    Several 80% cases have been documented in the XNA community. I've got one that's up to 80% only on the left side. Same with Shawn Hargreaves (XNA team member), who reports all their new high end sets having different (and uneven) overscan across the same model.

    No overscan on HDTVs (even non-tubes) is an unsafe assumption.

    There are some overscan tools you can get for nVidia cards->HDTV to fix this.

    hmm very interesting.. I need to ask my friends still in animation production where the cutoffs are... btw, if you're working XNA, does that mean you're over at bitheads?

    I'm on the forum, not the team.

    The cutoff is up to 20% on any side. This goes for every TV, regardless of type. If you have to scroll, set your drivers to compensate for the overscan.

    Viewable area on a 1280x720 set can be only 1024x576.

    That's too bad. The HD spec should have killed Overscan altogether,

    my tv is fine, it's the monitor that overscans, changing the settings in the driver does nothing.
