Any reason why 1280*1024 works with 1 card, not with other?

Hey all,


I have a AMD 780G motherboard with the HD Radeon 3200. I was playing NHL 09 about a month back and was doing so fine on 1280*1024 resolution on my HTPC TV at ok frame rates, but wanted something a tad better. My tv is a 52" Plasma, LG, 1366*768 TV. About a yr old.

anyways I decided 2-3 weeks ago to put HIS Ice-q Radeon 4670 512MB card in it to give it a little more performance as I want to play GTA 4 when it arrives on PC, as Ive played about 30% of it on a 360 but thats it. (the site recommends a 3850, the 4670 is comparable but a lot more silent and power efficient). plus since I do my gaming on the TV, the max resolutions I play arnt crazy, so this card serves me well for $95.00

I mostly use the HTPC for blu rays and x264 mkv files, with occasional light gaming.

Everything installed great, card is sooooooo quiet! love it, plus not extra power needed. My HTPC remains dead silent.


anyways, one issue I cant get resolved.

Before on the HD 3200, with NHL 09, I could play it fine at 1280*1024.

With the HD 4670, when i chose this resolution, my Tv tells me its an invalid format. I have to play it at 1024*768.

My TV played this resolution perfect before at full screen....

any help would be greatly appreciated. I have the lastest ATI drivers. Any reason why onboard graphics would do this fine with my tv but the 4670 doesnt want to?

Its the only game I have right now installed.

Not to sound condescending, but why would you want to send a 1280x1024 signal to a 1366x768 monitor? It'd just get downscaled to 1024x768 anyways, if it's maintaining proper aspect ratio. 1024x768 would be ideal as far as 4:3 resolutions go, since it fits correctly (with black bars on the left and right sides).

very true.

thanks for the info.

also NHL 09 doesn't have any Widescreen resolutions to choose from.

Im playing at 1024*768. Looks just as good anyways.

Im a pretty big newb when it comes to modern PC Gaming. I always had consoles for that. I sold my 360 to buy a new surrond system, and decided I wanted to try pc gaming again on my tv.

The last time I attempted PC gaming I owned an original radeon video card. (edit)


In the past I've generally used lower priced video cards only used for the basics/dvds

I just figured higher was better, so wanted to get as close to the native res as I can for the game.

In my case, 1024*768 is probably the best I can do unless Widescreen resolutions are suppported, correct?
