Overscan

savagcl · 04-03-2005, 03:33 PM

Wiley,

Cant help with HD, just starting myself but about the PC -

If it was a starter back in 2K, its best use would be for backups i think.
A small amount of speed (probably wont notice any difference tho)
could be gained by more RAM just because it could hold more stuff in
memory (meaning less harddisk reads). If it still has the original
graphics card installed then yes, a new one would help because of the
advances in tech during the last 4 years. Again, minimum speed
increase but a better looking picture with a new graphics card.
I would spend lots of money on it tho because of the age.

I picked up a Zenith E44W46LD back in September. Until recently I had only been using it to watch SD cable without any complaints. Recently I have built an HTPC with a MDP-130 HD Tuner card that sends 720p out over RGB. I also had a set-top HD Tuner for a couple of days but returned it because I decided to build an HTPC. To my suprise, my TV has about 6.5% overscan on all of the HD inputs and not just when using the HTPC. I can correct the desktop overscan using drivers and/or powerstrip, but that still leaves my tuner and any other devices I may hook up in the future with overscan that cannot be corrected. Is this something a tech should be able to fix, or am I just going to have to live with it?

Overscan is normal and assumed by TV broadcasts. It is not a "problem" per-say. HTPC's highlight overscan because PCs are made for an edge-to-edge display, a PC monitor. Set-top boxes like DVD players, cable boxes, etc. are all made to work with overscan.

dauger · 04-03-2005, 06:03 PM

How much is normal? When I did have the set top HD Tuner I remember watching "24" and about 1/2 of the channel water mark was being cut off. I don't know for sure, but I would have to guess that the water mark is even above the bottom of the image a little. Maybe I'm just being picky about it since I've been fighting it with my HTPC all weekend

Your ~6.5% is in the normal range. For the TV sets I have owned all show about 3/4 of the channel logo. This seems to be about normal, again the networks move the channel logo up and in a bit and many assume that you won't see the very edge.

RSawdey · 01-24-2006, 01:34 AM

Wiley, Windows knows all about widescreen 16:9 display & will keep everything correctly proportioned. Give the TV it's native res, 1280 x 720p @ 60 Hz. If your current drivers don't support that format, look for newer ones. I've also got an older computer running ME... at 720p.

Savagci, you're not in the right part of setup... select 'Adjust Display Properties'... then setup 1280 x 768 res, 32 bit color under 'Settings'. Then go to 'Adaptor' and set a refresh of 60 Hz (NOT! 'Optimal').

So, if you have dot by dot, does this mean that you don't need to worry about overscan?

lylestyles · 05-17-2007, 10:52 PM

i am having the same problem with overscanning. i am using an ati x850 xt with a Sony WEGA 50" 1080p Rear-Projection SXRD HDTV
Model: KDS50A2020

i have a dvi/hdmi cable connecting them. at 1920x1080 i can't see the taskbar. the only resolution that entirely shows is 800x600 which is unacceptable. is there a way to use powerstrip, or a similar program to create a custom resolution that accounts for the over scan? or perhaps a hidden setting in the tv's menu to shrink the picture? (it has a display area setting of -1 and -2 which both increase the size of the picture)

in powerstrip it shows the active pixels as being 1920 but the total pixels as 2200 for horizontal and 1080 active 1125 total for vertical. is there some way to make the total be 1920x1080? i called sony and they were less than no help.

i'm pretty bummed out so any help would make my day, month, and possibly year.

lylestyles · 05-19-2007, 09:20 PM

after some bad luck i fried my video card when plugging in a usb cable... dunno how or why.

i have done some searching and it seems like all the overscan problems could be solved if i could get into the service menu. multiple different sites have said that you enter the sony service menu by pushing display>5>volume up>power but that just turns off my tv.

other people have said that in the catalyst control panel you can force it to use HDTV settings which would shrink it to the right size, but i am using an nvidia card now that the other one is toasted.

anyone know how to get into the service menu on this tv? or how to essentially do the same thing that the catalyst control panel does, but with an nvidia card?

thanks!

HDTV Overscan fixes - ISF Info
Nvidia's new Forceware drivers cured it all. These drivers add Consumer electronic display support for DVI-based digital displays, such as widescreen plasma screens (CEA/EIA-861B) according to Nvidia's website. There's a nifty little program called NVKeystone I think in the download that allows you to adjust the screen size from corner to corner. I have my entire computer screen visible now. http://www.nvidia.com/object/winxp_2k_61.77.html

Yes only nvidea cards. Use Catalyst drivers for ATI.
