Differences Between Mvp 7.5 And 8.4

Clingpeach

Is there anything major?
I know one is active and one is passive. Ive only worked with the 8.4's and have found them very good.
How different is the 7.5 (apart from the price difference). How is the connectivity to a wap??

In terms of connectivity and usability, I've not had any problems out of the 7500s. I will say, however, that we have basically stopped using them and basically forcing any jobs that come through to go with the MVP-8400 panels instead. The issue that I've had with them is the video quality. Recognizing the fact that all of us in this forum probably recognize the difference between the display qualities of the two panels, not everyone does. After having seen the 8400s, almost everyone I come in contact with is very displeased with the appearance of the 7500s. If nothing else, you have to be careful of the graphics put on the MVP-7500 to try to keep it from looking washed out or showing visible streaking in certain parts of the image. At least that's been my experience with them so far....

8400 - 18bit color depth (262k colors)
7500 - 12 bit color depth (4k colors)

Yes, and passive or active makes a difference in how images/colors should be handled. There are highly complex dithering algorithms around for good color rendering on STN panels (passive). A bit like for video scaling, not everything is Faroudja-quality.

Thanks for all the input. This will be the 3rd WIRELESS MODERO in the house. It will probably be used at the Pool to replace a current VPN. Graphics are NOT as important as connectivity. Bearing in mind in the Westchester, NY area it will be used maximum 5 months of the year. And not every day.
The other 4 Modero's are graphic intensive still waiting on the firmware upgrades for that for VNC and split screen issues.

I have to agree with Matt. I sold one in the beginning, and have since told all my sales people never to sell one again. As far as connectivity is concerned, they are the same, but 7500 graphics are just awful.

Frankie

I agree. The graphics on the 7400 are not good. We've done a few but not many.

Clingpeach

Is it worse than using a VPN???

matt95gsr

I don't think that it's necessarily worse than a VPN, but I think it's the fact that based on the quality of the 8400, the wired panels, and just about everything else in live video-wise, the expectation is higher. And the fact that you're holding a pretty sexy-looking panel with not-so-sexy graphics.

the colour bleeding is quite a nuisance on the 7500s. especially when i try to create the same panel design across all panels within an installation. after preparing CV7s or 8400s etc, then loading a translated file into the 7500 is a sad experience. in some instances it's almost unreadable. in a way, colour wasn't worth the effort, maybe should've just done monchrome. and if someone suggests changing the graphics, i'd like to know what to. even the setup pages within the panel bleed.

one other shortfall of the 7500 compared to the 8400 is that by default you only get one battery. an extra battery is included with the 8400 (so the AMX website says).

otherwise, networking etc all appear to be the same. so if battery and visuals are not so important (yeah right, smaller with ghosting ) the 7500 should do fine, particularly for the price difference, which of course makes everything relative.

oh, and the 7500 is a bit lighter. that can be a benefit to physically challenged users.

The first 7500 we received looked so bad we sent it back to AMX because we thought it was broken. We also sent back the second one too. Only use it if money is an issue.

Agrreements all round concerning the MVP, but the 8400 is a fair bit dearer so I've put in lots of the 7500s.
You have to basically avoid stright edges in your touch panel designs at all costs. It is a problem if you want to use a common panel design.

I like the viewpoints!
RF has a lot less issues than the 802.11 panels.
If AMX only brought out slimmer versions of viewpoints with more than 255 button capability I'd be set.

For outside use I would say 8400 is the only choice. I have trouble with 7500s in a sunny room.

One other comment - I use degrees of transparency sometimes on 8400s to make "less important" icons less obvious or to highlight more vividly a selected source. This is not even an option when using 7500s. Double check that everything is 255...

great point on the sunlight, a bright room can make a 7500 unreadable.
and the transparency issue is very valid. i am just redoing an 8400 design, have a lot of transparency, now i'll have to rethink that to make it 7500 compatible.

as for RF, you can use it from the MVPs if you want. it's there ready to go.. all 255 buttons and IR too of course. check the setup options for the buttons. but i prefer Wifi more than RF.

i agree with champ. there is a compromise, but you pay a lot less for the 7500. it's generally fair.

I have to agree with everyone on the graphics issues the 7500 brings to the table. I also have first hand experience with the 7500 in an outdoor environment. The first wireless touchpanels we sold were 2 MVP7500s. The client wanted to be able to use them at the pool, so we setup APs in a way to allow it. Everything was fine when we tested on an overcast day, but the minute there was any amount of sun, the panel became almost useless. You could see the graphics if you shielded the panel from the sun with your bodu and arms and squinted really hard

Thanks for all the input. I will stick to the 8.5 for the pool area. The vpn was not great in the sun light either. In fact even a laptop isnt great in the sun so not sure its a great analogy. I will play around and use either one. Graphics are really not important outside, as mentioned before. Its the CONNECTIVITY which is the main issue for me

yuri

if connectivity is the issue, use a wired panel :P

maxifox

Yes, I completely agree with incovinience because of the sun...Just thought on using Mio Remotes outside...

Be aware that the 8400 will not hold up in bright sunlight either, the only touchpanels that I know to hold up in bright light are the old EL+ (Amber on black) panels.

I have stopped using the 7500 too - It may be my impression, but the 7500's touch overlay seems to be really bad and I have encountered at least two panels where touch areas could not be made to match the graphics closely enough to reliably select a 60Wx35H button. The 8400 appears to fare much better in this (and other aspects mentioned before).

(For that matter - I still don't understand why AMX abandoned the reliable 8-point calibration - this really should be re-introducted as 2-point calibration is highly in-accurate)

I completely agree with you.
