Tom's Hardware > Forum > Graphic & Displays > Nvidia > I cant have an output resolution of more than 1024 by 768

I just got a 42 inch tv (pretty sure its HD cause its a flatscreen and...big--i got it from a friend) and i connected it to my laptop. When i went to the Nvidia control pannel, the maximum resolution i could set it as was 1024 by 768 :(
i have a NVIDIA GeForce 7150M on the laptop, and although i couldnt find its max supported output resolution on the nvidia site but lower quality graphics cards have a much higher max than 1024 by 768 so i assume that my card can go higher.
I have a 7pin svideo adapter, but the connector connecting it to the tv is 4 pin svideo on the laptop side and composite on the tv side Could this be the reason why it wont go higher?
Please help, thanks :)

i dunno, that is a really old card. Try updating the drivers on it but i wouldn't be surprised if it didn't support any higher resolution. After all that card is only meant to display picture to your small little laptop screen, not a 42 inch tv

It'quite current with HD display, when used with the vga output, to limit the resolution to 1024x768. In order to get higher resolution, you should use a video card with HDMI.

might think to google your screen, it will tell you the max output.

most lcd tv's put out 1024 by 768 or 1920×1080 . it wont make a difference if you have the best video card in the world. if thats that max resolution then thats the max resolution.


side note, LCD tv's are not ideal for computer's........

Your TV is probably 780p "1024x768" You can't run it a higher resolution then it supports. S video is like the crappiest way you could possibly hook it up also.

S video is for more like 420p resolutions.

Your better off with DVI or HDMI.

Yep, it is not the video card that is the problem, it is the TV you are hooking it up to. It won't support any higher res than 1024x768.
And yes, just because it is a big flat screen TV does not mean you are going to get a fantastic picture by hooking it up to a computer.

For those who believe the "old" video chipset which is the culprit, you're wrong. Even GeForce 5 series and Radeon 9xxx series cards are capable of such resolutions. (Note that GeForce 7 series chipsets are used on widescreen laptops all the time. Please refrain from spreading misinformation.)

What is likely the problem is the standard (read as, not widescreen) output limitations related to the even "older" S-Video port. Most modern laptops have a built-in VGA output, and this is the port through which you actually should connect the TV. The S-Video port would work just fine for a standard definition monitor or television, but this is a widescreen, so that's not the case here. Newer TV's actually have VGA input ports on them. If yours does not, does it have a DVI input, or perhaps HDMI? If it does, a simple VGA-to-DVI adapter along with a DVI-to-DVI cable, or possibly (though I've never actually tried this myself) a VGA to DVI adapter paired with a DVI-to-HDMI cable, might do the trick. Sadly, if it has neither of these ports, then this model's a bit of a dinosaur as far as HD LCD widescreen TV's are concerned. I'm not sure if there are VGA-to-Component adapters available. Consult the PC manufacturer and see what they say about it, because there should be a means to do it.

What you could also try fiddling with is the nVidia Control Panel. You could disable the SSID function for the Monitor, (or in this case, the TV) then manually set the resolution to match that of the TV. As someone mentioned, most widescreen HDTV's that size have 1920 x 1080 resolution, however there are several still around that run at 1366 x 768, not 1024 x 768. (1024 x 768 is a standard definition resolution, not widescreen.) A little research on the TV manufacturer's website for that specific model would shed a little light on that matter. Read the sticker on the back of it to find the model number.

Good luck!

Thanks for all the answers,
the TV is definetly an HD tv, and is definetly capable of HD resolutions,
it does have HDMI connectors, and has a resolution 1080p (1920x1080) and 1,080i . So i guess that the problem is with the connector and not the TV or the Computer. So should i buy a vga to hdmi converter/cable? would that work?

use DVI to HDMI.. you cant convert an analog signal to HDMI by an adapter.. another thing.. is it a plasma tv? if then, 1024x768 IS most likely the resolution of the tv, as plasma uses non-square pixels as old CRT tubes.. then you'll just have to feed it with and 1080p signal, and use some reduced/increased overdrive..

well doped, according to this site,
http://www.buy.com/prod/philips-us [...] 07958.html
it is an LCD HD tv with a max resolution of 1920x1080
and you can convert VGA to HDMI, thats what these do:

would a VGA to component cable have a higher output resolution that the svideo to component cable?

Yes. But using one of those VGA to HDMI converter boxes seems like quite an expense to display your laptop on an HDTV.

Reply to RazberyBandit

yea it does, my friend told me about USB to HDMI but i looked it up and it doesn't support 1920x1080. Is there anyother way (besides getting a VGA to HDMI converter) that i could get the full resolution on my tv from my laptop?

Reply to seleucid9

You mean besides selling it then getting a newer TV with a PC input? Honestly, aside from one of those converters, that's all I can think of...

i was looking on ebay and i found this :

is that just a scam or will it work?
it seems too good to be true but i just wanted to ask :)

I dunno if it's a scam or not. It's in Hong Kong... Who knows what sorts of gizmos they have there already that we don't in the US? However, since neither Newegg nor Radio Shack (between the two, they have just about anything and everything) sell any such VGA-HDMI cable, I would tend to believe they don't work.
