What I meant was, I did a bit of research and from what I’m reading, HDMI and DVI are using digital video signals… Presumably, they’d both lag, because they’re sending the video signal thru the same media, does that make sense? So I was wondering if the lag would apply the same way if someone were to use, say, an HDMI-to-DVI adapter to use their system on their monitor, assuming they didn’t have a VGA port since a lot of newer monitors don’t have VGA ports anymore.
As for the VGA/DVI adapter, yes, that’s what I meant. If there were no VGA ports, and someone had to use a VGA-to-DVI adapter, I’m just wondering if the adapter would introduce any lag… You seem to believe that it would, I can see why, but I mean, the transmit is still analog but the input would be digital. I guess we’d probably need to test it out to know for sure though.
Orka you gotta let me know how the setup works! I’d like to know if the HDFury 2 is worth the upgrade! :tup:
How do CRT HDTVs fair (assuming you can still find them)? My understanding is that they don’t have the notion of a “native resolution”, so does this mean no upscaling lag?
So what you’re getting at, is that monitors wouldn’t post process on a DVI input if it’s the default one? Like they would treat it like other monitors and VGA? I’d guess and say no in most cases, but I don’t have any proof. My guess is because VGA is an analogue signal, there is something stopping them from easily ‘improving’ the image from the signal, so they don’t bother with it. Just a guess.
I think it would be pretty strange if that worked. As long as the TV was getting some sort of signal through the DVI port it would try and add post processing, even if the signal was just noise. This is based on the assumption that post processing IS the cause of course. As you can see, I’m fond of guessing and assuming at this point. Testing is not exactly the easiest thing to do.
CYBORG COP: The first post mentions that HD CRTs do lag.
Genestarwind: You certainly can. Need more details on what connection you’re trying to plug into and what console you’re using so we can tell you what you did wrong.
Zanken, I can probably test it, as my HP monitor happens to have DVI-only ports. I’ll see what I can do about giving it a shot sometime this week. I’ll post up my results.
My el cheapo Sony W120 camera isn’t quite fast enough to get accurate shots of the timer on a dual monitor setup, but a few of the pictures seemed to indicate that our Sony KD-36XS955 HD CRT lags behind my NEC 22" CRT monitor by about 20ms.
That’s a pretty safe assumption considering the post-processing is what causes the large majority of the lag. The challenge is trying to determine if the TV actually does any PP’ing. A lot of the time that sort of thing isn’t listed in any of a TV’s specs, in my experience.
Placed an old CRT monitor next to the TV and took pictures with a camera set to high shutter speed. Average ~10ms lag at 1080p, a few ms more average lag at 720p. Have the TV connected through DVI to HDMI adapter.
This might be the wrong place. but maybe someone can help me.
I bought a linksys router yesterday. I’m trying to be online on the pc at the same time as my xbox would be online.
The weird things is when i get online , i cant use xbox, but when turn on the xbox and try to sign it, it will automatically DC my internet and i can only be on xbox. Can anyone help please!

Hey guys, can anybody fill me in on which of the “lesser” brands is the best? ie. Vizio, Insignia, Dynex and probably a bunch of other brands I’ve never heard of.
I just need to get my gf a new tv. She’s been rocking a 13" VCR combo since she was probably 8 and I can’t stand looking at the damn thing anymore.
I’m thinking 32" 720p LCD. Lag is a small issue. She plays some Rock Band and Guitar Hero on XB360. Is there anything decent I can get in the $400 to $500 range?
I have all three of those makes and the Vizio is the best followed by the Dynex and then Insignia.
I have been testing some of the Dynex and Insignia models for Best Buy and they should be passed over for gaming stuff - they have do not have advanced settings/menus like the Vizio.
I just picked up a Panasonic 50" G10, and I’m having trouble turning 1080p mode on my 360. I tried both VGA and components (the latter worked with 1080p on an older visio plasma.) The screen just turns black for a few seconds and turns back to 720. My ps3 does 1080p no problem on both plasmas. Is there some sort information I’m missing here, Or can you not do 1080p with VGAs?
And while this is a 24", and yours is a 23", it still would be nice to know what model you’re using, and if you did any actual LAG TESTS (even just GHIII) so I can figure out if it’s worth trying or not.
Ditto for you. But you maybe joking. In which case, that’s kinda funny, actually.
I just got a new samsung LN32B540 tv from costco the other day and i just got my hands on rock band 2 to do some input lags tests to post in the HDTV section.
But i have run into a problem. When i do the video calibration i am getting a constant 46ms for every mode that i have the TV set in. Through component cables i am getting 46ms, component cables +game mode i am again getting 46ms. And when i connect through VGA i am getting the same.
Isnt VGA supposed to have the lowest input lag, but for some reason my tests are not showing this. Anyone happen to know why all the modes for my TV seem to be giving me the same exact results?
