Monitor Mess

[wcndave]

When i built my cab, i had an old 22" 16:10 and decided that 24" inside size was nice, and allowed me to get lots of pieces from my wood.

now i look to get a bigger screen, i find that 24" is about 1" too short for a 27" monitor.  this would mean redoing front / back panels, top, shelves, marquee holders, front glass and so on... bugger...

26" 16:10 asus would have been great, cos with 19:9 you get side bars anyway. however it's not done anymore.  the death of 16:10 and 4:3 is bad, especially as it gave so much more space on a normal desk....

so I have gone for the dell 24" ultrasharp, which is 16:10 and about the biggest monitor i could find that would fit.

however now having ordered, i find out that my current samsung 22" is 2ms and the dell is 8ms...

so, now to my question finally...

8ms vs 2ms.  On MAME, will it matter?

I have never worried about this before as PC gaming is not my thing, so i have no clue about the response times of monitors.


many thanks

Dave

I'm pretty sure I wouldn't tell the difference. And I have been playing at monitors with refresh rates way slower than 8ms...

Response rate is not the same as input lag.  Input lag is what you should be concerned with.  Response rate is usually fast enough for gaming, 2ms or 8ms is fine.  Input lag on common LCD's can easily reach 50-100ms, which is a major hindrance for any kind of gaming that takes any timing or reflexes.

Response rate is the time it takes for an individual pixel on the panel to transition from full black to full white. 

Input lag is the processing time that takes place in between the monitor receiving the signal, and then actually displaying it.  This means when something happens in-game, the monitor won't even start to display it until after a certain time period, measured as input lag.

signal is output from source (computer/game console) -> signal travels through video cable and reaches monitor -> monitor processes signal during input lag period -> signal can actually be seen on screen

When using an analog CRT (tube-type) TV or monitor, the time period from the signal being output from the source to it actually being visible on the screen is relatively instantaneous.  Things are very different with digital displays.

Oh, and matsadonna you are confusing something.  Refresh rate is something entirely different.  It refers to the vertical scan rate measured in Hz, which determines how many frames are displayed per second.  Modern monitors can display a variety of different refresh rates.

Dave, which are you talking about?  I'm guessing if you were able to find it listed on a commercial site it was response rate.  LCD manufacturers kind of sweep input lag under the rug. 

All this being said, is this the monitor you're talking about?

If so, that would be an outstanding monitor for gaming.  It has been measured at only 9.3ms of input lag, which is only about half of a frame at 60fps (1 frame at 60fps (60Hz) = 1 second (1000 milliseconds) / 60 = ~16.6ms).

Be sure that the model number is definitely Dell U2412M, as there could be certainly be other 24" Dell UltraSharp monitors that don't have this low input lag.  It depends on the type of panel used.

Thanks for the very detailed response.  That is the monitor i have yes http://www.amazon.co.uk/gp/product/B005LNDPPS/ref=oh_details_o04_s00_i00

It seems really great, the size is actually perfect, I think that a 27" might in fact be too much anyway, with a slim cab as you stand quite close.

So i am actually quite happy in the end.  Will have to post some photos one day!

Yes, my bad. I was referring to response rate. Sorry for adding confusion.

Anyone playing Guitar Hero on a LCD TV should know about the input lag, since it requires recalibration in order to be playable.
