The New Definitive HDTV Lag FAQ

I’m a graphice designer so high resolution and accurate colour is a must for me. CRT is still the best display you can get. The thing is High resolution isn’t new, and why haven’t they taken it higher, is it so they can roll out super hd soon an dmake more money. Also changing resolutions doesn’t seem to cuase any problems on my mac, so why does it on tv’s, if the technology is there and it’s not that expensive, why is it on top of the range tvs the problem of showing traditional resolution on a hd tv result in a poor image when it is easily rectified on cheaper tv’s.
I just replaced my nec mitsubishi, with 2 similar monitors in black without the usb hub [originally £500] for £1.50 each. Yes second hand but from an office clear out. The thing is people assume crt monitors are old technology and that LCD etc are far superior, when the technology is still in its infant stages. Initially the viewing angle was my main gripe, but there are so many other elements I never thought of or new about coming to light, you really need a degree now to buy the right tv, I probally will be corrected a number of times for misunderstood facts. Anyway if you look around there’s a widescreen sony srt it has amazing resolution and if someone doesn’t appreciate what they have you could probaly get it cheap on collection, I doubt posting will be an otion.
But now the flaws are slowly being ironed out, the fact that it will be so easy to clean my desk with the 2 giant bolders replaced by slim lighter screens, is slowly but surely becoming more important than my designs being printed with a true black and my yellows not having a green tint to them.
Now is this lag issue due to videcard processing and is someone on msn or skype who wouldn’t mind me picking there brains about hdmi, vga, and why why crt tv, wont accept the signal from my powerbook through svhs. I thought I knew everything I needd to know, the someone opens another can of worms, but the wroms have legs and im confused all over again.

I was under the impression that even mid-range Dell LCD monitors gave you, like, 96% of the spectrum or some such, whereas higher to high end NEC LCDs and the like gave nearly 100%.

The higher end graphic design monitors are ass for gaming, mind, but the colors are impeccable.

As I see it.

I hate to “dual post” but thought it is relevant to this thread:

Couldnt you buy a monitor made for cabinets, mount it somehow, and hook it up to xbox via vga?

I’d have to assume there would be low to no input lag on these…

Hello everyone!

I am looking at getting a Sony nsx-32gt1 tv, this is the Google tv that Soony sells.
Anyone have experience with this tv? I dont see any input lag #'s for this tv and I plan to play fighters heavily on it.

Any input on that tv would be VERY appreciated, thank you!

Hardforum. Not exactly a scientific study. But the folks there say ~30ms or just about 2 frames. So I wouldn’t expect any better and it could be worse. Anyhow, there you go.

Sony TVs have typically had a poor track record with input lag anyways. Picture quality is a different story, but that’s not what this thread is about.

EDIT: And if it sounded like generalization, it probably was. However, don’t listen to generalizations for the most part; it comes down to the individual panel!

I am starting to think those may be Japan only…I hope I am wrong.

Well they’re Japan exclusive for now. I guess it then depends on the Japanese market in terms of whether they’ll make models to sell in other regions. Could also be a beta test of sorts to gauge interest.

i could have sworn i read over on neo gaf that these were coming to the states. i thought they had model numbers and everything. i could be wrong though you guys seem to be up on the ultimate street fighter lcd more than me

Has anyone tested the Asus ml238h ****

I just wanted to clear some things up in here.
it seems some of you seem to think VGA , DVI and Component cannot give a clear picture or a full HD 1080p signal.
COMPONENT, VGA and DVI connections CAN output 1080p video @ 60 frames/sec
those who keep thinking VGA or DVI cannot do this need to realize there is no difference over short distances using these 2 technologies. however the main advantage HDMI has over these 3 is audio support.

in fact both DVI and VGA are capable of delivery resolutions even higher then 1080p.
which is why HDMI 1.2 was phased out of PC video cards and instead are being replaced by DVI and DISPLAY PORT.

don’t believe me here is a video of a captured hd stream using HDFURY connected to a black magic intensity HD capture card over COMPONENT in HD with NO LAG.

[media=youtube]0VRY84vqtlI[/media]

also HDFURY indeed DOES indeed remove HD LAG to from the content stream. to the guy with the sony bravia the reason you are still getting lag is because the panel engine is crap and is prolly using something less then bit 8 bit post processing engine.

here are some results on 3 different panels with and without HDFURY.

Sansung 223BW/S-Panel [1.8ms weighted avg lag] ? connected via HDMI ? HDFury ? VGA
Samsung 2333HD [21ms total avg lag, 12ms weighted avg lag] ? connected via HDMI
Asus VH236H [19ms total avg lag, 8-9ms weighted avg lag] ? connected via HDMI

the average time output with HDFURY is 1 to 2ms compared to others.
there are various reviews and sources online that cover this as well on net and all over youtube as well as gaming sites.
here is one video review from tekzilla which btw they removed from their own site since they were threatened by the MPAA.

and last here is a visual display of how HDCP works with protected content such as output from the PS3 here…

left side PS3 with HDCP over HDMI:
the pic on the left shows red which indicates a protected stream. the blue line displays other options once prerequisites are made. in this case on the left if you chose to use an HDMI to DVI cable your DVI output will still be encrypted and the monitor it connects to will still need HDCP compliant DVI sockets. also your only audio option since DVI cannot carry audio would be optical toslink output.

right side PS3 with HDCP removed over HDMI connected to HDFURY:
this pic on the right shows green which indicates a digital signal in the clear with NO HDCP. the blue represents new connection options once HDCP is removed. DVI, VGA and component(YPbPr/YCbCr) with audio options for RCA stereo OR optical toslink.
this is a better solutions since all these outputs will not give you HD LAG or lag from decompression times associated with HDCP over HDMI.
ALSO this method allows one to gain HDMI output once again using a DVI or component converter box to HDMI.
and last EVERY panel has some hd lag.

EVERY panel has some lag. some very little some a lot. anything connected over HDMI for sure will have it due to the way hdmi has to be compressed and decompressed in real time and the way the panels video engine computes this data stream. which is the main reason why HDMI altogether is being replaced and scrapped in favor of DVI, DISPLAY PORT and the new standard coming up HDbaseT over RG5 and RG6 ETHERNET. which can be seen here…ethernet is cheaper. already everywhere and can provide power, video, audio and data with greater distance that HDMI cannot.

hope this helps everyone understand everything better.
if anyone got questions just ask away. and there you have it… don’t even bother with HDMI.

wow no replies?

I’m glad someone is posting some useful information in this thread, but there are a few things that should be clarified.

HDFury is a high quality and fast HDMI/DVI to VGA converter, which handles HDCP handshake and does decryption of the video stream very quickly. It does not “remove lag”. You still need a display with a VGA port that processes VGA input with very little delay for it to be useful, and it also needs to accept VGA input at the native resolution of the display (or at least have a fast scaler).

Direct HDMI input to a display can be decrypted and processed as quickly as (or faster than) the HDFury; it just depends on your display.

Your favored solution with the HDFury uses HDMI! :slight_smile:

QFT. The HDFury is great if your panel 1) Does post-processing on HDMI, and 2) Is significantly faster through a non-processed VGA input. It does NOT eliminate lag - the lag entirely depends on the panel itself (inherent panel speed + post-processing from whichever input), but HDFury can help bring this down to the best levels for your monitor/tv, given that the VGA input does not suffer post-processing delay.

it converts from hdmi input to remove hdcp and outputs into vga or component.
its favored for removing hdcp i particularly use it for video capture.
and for ps3 output there is no other way but to use hdmi to get 1080p output.
that’s why there are hdcp stripper like the hdfury that exist.

it also outputs to component. hdfury does not output to hdmi. never did.

Yup, I should have mentioned that the newer ones output to RGB or YPbPr component via VGA -> RCA breakout cable. So for lag avoidance purposes this is also good if you have a RGB or YPbPr component input that has low input lag.

I’ve spent about 3 hours reading through this damn thread and google, but have yet to understand any of this stuff. Whats the largest HD TV out there that has minimal lag? Around $3000 would be nice. It would be nice if it had those new features like web surfing and 3D capable, but gaming is my primary concern.

Please help!

Have you tried HD Fury on say a tv at least 32" at all?

I believe the results posted but I’m just curious what TVs are known to not lag a great deal through the vga port.

I use it on my 27 inch asus and my 46 inch samsung.
and yes i do notice with the hdfury hd lag is virtually gone in the bigger screen.
on my 27 inch the panel is pretty fast so i dont really need the hdury.
but for color correction and vga output i use it to save the extra hdmi slot on my monitor for my xbox.
i only used the hdfury initially to remove hdcp. the hdlag cut to 1.6ms was a bonus.
but compared to other hdcp stripper hdfury was the only one that cut hd lag times.
the moome mux-hd and gameswitch are only splitters that by chance remove hdcp as well. however they still output in hdmi and protected dvi. so for gamers those really aren’t proper solutions especially if you plan on capturing gameplay in high res.
as far as lag goes for tv’s on vga port. you can find results on most tvs through tests done by others on av forums.
i have the sammy LN46A750 and i did research on this heavily before investing in it.
the best thing i can say is always research and try in store before you buy.
sony’s and westinghouse are notorious for having poor hd lag performance btw.

Never said it did to HDMI. Also, where are your lag tests for your 27’ ASUS please; also to your large TV while you’re at it? If it’s low enough I might consider getting it…

check the avs forums there tons done on asus. i based my decision on that and my own tests.
as for the sammy i never did any reviews or test on that. but i can assure it got none.
i mean if you really want i can do a small video but that’s a whole different thing.
