Graphics card - does resolution matter? (1 Viewer)

[MrHolst]

Hi,

I have my eyes on EVGA e-GeForce 7600GS w/ Passive Heatsink for my HTPC, but it specifically does NOT support the resolution that matches the physical resolution on my Samsung LCD LE-32M71B: 1360X768.

I would imagine that if the card produces a resolution matching the exact pixels on the TV, that would lead to best picture. At least my logic tells me that no further conversion has to be done on the resolution, so in theory that is good!

Am I right, or does this not matter at all? I would like to hear some arguments in either case.

Names on cards producing 1630X768 are also most welcome - they tend to be hard to find...

Well, the physical resolution will most likely be 1366x768 whereas the gfx card's driver will restrict you to the "1360". In addition even digital TVs do a stupid overscan and downscale to get rid of "noise" in the tv broadcast.

You should be able to setup a custom resolution in nvidia's control panel for the TV' but you may be out of luck to get a 1:1 picuture since especially Samsung's TV sets are notorious for bad PC input

Actually the TV is featured to drop 3px in each side to support the 1360px, so that should take care of that.

My current card is also Nvidia (Geforce4), but I can't find anywhere to setup custom resolution; rather I can only choose between a few fixed resolutions. Am I missing something?

Besides the setting discussion, do you agree that it will be best if one can fine a one-2-one match?

lcd tvs are typically 1366x768

most gfx card will do exactly 1366x768 using powestrip or advanced driver functions

most tvs will not allow 1:1 pixel. samsung are notorious for this.



I have 1366x768@66Hz for regular pc use, but my tv only accepts 1280x720@50/60 Hz if I want smoth video (66 Hz gives stuttering). In this case it will scale the picture and crop some % off borders and this is impossible to fix due to incompetent tv engineers!

is it possibly to have cloning on simple TV with for example 1280x1024, but with scaling? All driver restrics resolution to 1024x168 on simple TV - but I see no point in it. TV can't display 1024 and driver use some form of scaling, so why it can't scale from highest resolutions?

I too want to use the my tvs native res and have been doin a tiny bit of experimenting myself along these lines,, primarily to find an onboard vga chipset (went 775 meself)that will do this res,,
as you say nearly all lcd panels at 32 & 37 inch use this so why are the damm vga designers so blind to this,,
all that power in a pc why the hell use the tvs scaling which will underperform the pc
it also makes sense to not use external vga to keep power and noise down if pos but have to say not having much luck
intel 950 boards wont,,new abit fatilityf190hd boards advertised as having x700 engine wont do this either,, was tempted several times to bin whole project as been on this a month and lots money/time wasted
mb manufacturers need to get wise the one that sorts this issue will get my future business
most companies waste too much effort on useless gadgets
have seen in various shops etc scaled hd picts shown thru dvi/hdmi interfaces not in panels native res and the quality was not as good as using vga line in native res
