Samsung 710 N or T - Does Dvi makes such a diffrence?

[Wizard12]

I've been searching this forum for information about the 710, and some people say that DVI doesent make so much diffrence, others say it does.

as you know the 710 T with DVI cost more, and in europe there's a problem of availability, meaning I can purchase it here...yet If I get unlucky and have problems with it (dead pixels for example ) reaplcing It will be a major pain in the a$$.


your opinions ?

I wonder the same thing myself.

I just recently got a new system at work with a Dell 17" LCD is running on VGA (no DVI) and the image quality is extremely good.

thing is I bought a dual DVI card

(it was actually cheaper than every other card by a considerable amount )

so to me it looks kinda dumb connecting a dual dvi card to a VGA lcd through an adapter

:/

The 710T blows away the 710N in response time (black to white) and black to grey. You wouldn't think so since they are both rated as 12ms panels, but Xbitlabs tested both the 710T and the 710N and spells out the results (I don't know why they took the graphs down but the writeups are still there. Skip to the introduction to see all of the 17" LCD's they tested and the conclusion where the 710T essentially comes out first.

The 710T was tested as having 12ms response time in black to white (9ms rise and 3ms fall) and (the best ever achieved at Xbitlabs) up to a 17ms black to grey response time.

The 710N was tested to have a 15ms response time (10ms rise, 5ms fall) and up to a 29ms black to grey response time (about average for a 16ms panel).

Note that black to grey response times are often significantly higher and account for ghosting on monitors. I had a 19" 191T ('rated at 25ms') which had an ~80ms black-grey response time (!) that ghosted a lot in games. I also had a 173V (also 'rated at 25ms') that had a ~25ms black-grey response time, and this panel barely had any ghosting.


Tom's Hardware also got exceptional results from the 710T - apparently the 710N isn't just a "710T minus DVI" - the 710T also has a superior panel.

Running a 710T myself I can attest to it's quality. It would seem that even if you will be running VGA for the time being, the 710T is a better buy (it has connections for both) since it's a better panel with lwoer response time.


Be careful when buying LCD's. Response time isn't the be-all end all measurement. Response time is supposed to be the full rise to fall response time in a black to white transition, but manufacturers are often several milliseconds higher than the rating. Again this makes the 710T's actual 12ms quite impressive (and the 17ms black-grey transition even moreso).

You know I looked at them side by side in a store 710T ( Digital ) and the 712N*same as the 710N Im told* ( Analog ) and with the $htty demo input they had I couldnt tell a big difference, so I bought the 712N.
I ended up seeing a 710T deal online the next day, so I bought it since it was such a good deal. I figured I would keep the one I liked best + sell my other one for close to whatever I paid for it.

Long story short I ran the two side by side on a dual head mirror for about a week( both calibrated with Avia Video Essentials ). I ended up keeping the DVI and paying the $100 premium. I definately noticed a difference.

Card was a 6600GT at the time.

what res are you running?

I heard that the diffrences are only visible at 1278x1024+
moreover I read somewhere that dvi limits the refresh rate to only 60fps...

are those true?

I was at native, 1280x1024 most of the time.. I would run 1024x768 in some games if the card didnt have enough oomph for them. I noticed the difference at both rezes, and the DVI definately scaled down much better. I have been told the quality degredation can have alot to do with the cable and video card for the analog systems.. And if matched properly the analog can look just as good as the digital at these resolutions.. In my case, for whatever reason the DVI looked better during my normal use so thats what I kept.

Im not 100% about the refresh, but I believe it is up to 75

Right now I am at 12X10 all the time since I upgraded my card

You don't want to be running your LCD at anything but its native resolution, but for games a step down in resolution isn't too terrible since the Samsungs have excellent scaling.

Btw native is 1280X1024.

Re: refresh rate. DVI does lock the refresh rate at 60 Hz (not 60fps, it doesn't affect game performance). However, 60Hz on an LCD is incomparable to that on a CRT, since CRT's draw their screen line-by-line while LCD's draw the entire screen at once. 75 Hz is the minimum for 'flicker free' on a CRT (and many people, myself included, would argue 85 Hz is needed for true flicker free operation). However, due to the differences in technology, LCD's dont flicker at any resolution.

Nonetheless, if you want to complain about it all the same as many users here tend to do, you can view 60 Hz on an LCD as a 'limit,' just like how some people can't stand the 150mph electronic limit of their new sports cars .

I've found that analog on my 710T looks worse than DVI. The text has an odd hue to it, and doesn't look at sharp. I have two side by side, so the difference is easy to see when I am using them both.
