Acer AT3705-MGW 37" LCD TV

Recommended Posts

I'm wondering if anyone can give me some pointers.

I was using the 3705 with my desktop computer that had an Nvidia 6600 in it. I had played around with custom timings and came up with one that seemed to do 1920x1080 30Hz in interlaced mode (60i?). It worked really well and I've been using it for many months as my computer monitor. Oh and this is through DVI as well.

I've just built a new computer with a Nvidia 8600GTS in it. I wanted to be able to play 1080i content from this since I've got a HD videocam. The old computer couldn't manage this, only 720p. Well surprise, surprise I can't get it to work properly. In fact playing around with it is so unreliable that I've had to plug an old VGA monitor in as well since I keep losing the screen and it doesn't reset back sometimes (very frustrating). I have all the settings from the other computer, but the new drivers seem to do the advanced timing differently and not all the numbers match.

Any suggestions? Trying to find info in this thread is difficult, though I know it is here since that's where I got the info originally. I don't care about 1080p, I just want 1080i which I know works with the old computer. Using the HDMI port isn't preferable since the HD tuner is running through that.

It is most frustrating. I'm currently using component out, but that looks terrible and can't seem to maintain consistent brightness and desktop resize settings.

I can't believe this thread is still going hehe..Bugeater I recently updated my driver and somehow managed to fudge the Nvidia settings to accept 1080p again.

Lat week I updated my card to an 8500GT and could not for the life of me get it working. I ended up adding a few lines into the registry to re enable the old Nvidia settings front end.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvCplApi\Policies]

"DevPolicies"=dword:00000000

"ModePolicies"=dword:00000000

"ModePersist_GPU:0_Mode:0"=hex:00,00,00,00,40,00,00,00,00,00,00,00,00,00,00,00,\

05,00,00,00,00,00,00,00,05,00,00,00,00,00,00,00,00,00,00,00

"LutPersistDesktop_GPU:0_Head:0"=hex:00,00,00,00,64,00,00,00,64,00,00,00,64,00,\

00,00,64,00,00,00,64,00,00,00,64,00,00,00,64,00,00,00,64,00,00,00,64,00,00,\

00

"LutPersistFSVM_GPU:0"=hex:00,00,00,00,64,00,00,00,47,00,00,00,47,00,00,00,5a,\

00,00,00,45,00,00,00,45,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00

"ContextUIPolicy"=dword:00000001

"CplGroupUIPolicy"=dword:00000001

"TaskbarUIPolicy"=dword:00000001

Add the above to a blank text file then save as oldnvidiafrontend.reg. Then double click on the file and it will ask you to add to registry. Say yes and Robert's your mother's brother. Do do a system restore point before this, though..

Bugeater, 1080p is so much better on this monitor than 1080i.

One thing I've noticed with this new card is it will not properly do 75hz or 72hz 1080p.. My old 7300gs and 6200 must have been freaks or this one is a bit of a dud..

cheers,

Anyone with this unit experienced something similar to burn in?

After watching the cricket I noticed a purple shadow of the score in the top left of the screen. I also noticed vertical bars of purple.

I sent the unit back to Highpoint but as usual they didn't look at it properly.

Is burn in possible on an LCD or is it something else wrong?

Yes I've had it. And it's not really burn in, but image persistence. The good thing is it tends to go away. The bad thing is it can take a while. And it's actually pretty normal with LCDs, but they just don't tell you about it.

I first noticed it when playing a PC computer game though the TV. It was an RPG (NWN2) and I ended up with the outlines of the HUD "persisting" when I was watching TV. I started playing the game through a VGA monitor after that.

From my vague understanding it has something to do with ionic impurities in the liquid crystal. These migrate if the current across their cell is maintained for long periods. Then the liquid crystal tends to stay in one state. The impurities will tend to diffuse back over time, meaning the persistence vanishes if the original image is removed. (I'm sure this isn't exactly correct, but it was my rough understanding of what I've read and my passing knowledge of liquid crystals) :wacko:

Highpoint/Acer said they couldn't fix it so they said the would replace it through the original dealer.

As it happens the dealer no longer sells Acers, and they gave me a refund which paid for a brand new Panasonic Plasma which is ridiculously better than the Acer.

I now have a spare Acer remote control if anyone wants one for a special price.

Just went to switch my 3705MGW on, and click, acer splash screen appeared for a split second and then nothing... power button doesn't work after that. Tried a couple of cycles with the rear power switch, same thing happens. Even unplugged it for a bit... nothing...its still under warranty... I'm assuming its probably not a big thing to fix as the panel is still fine its generating the splash screen before going off, so I'm thinking power supply or mainboard...My question is more to do with dealing with Highpoint, they don't seem to have had much in the way of positive feedback in the past and I was just wondering if anyone's recent experiences were any better? (please let it be yes, please let it be yes, please let it be yes!)

I'm getting rid of my Acer AT3705-MGW. Was bought in March of last year, so warranty is bye-bye, I think. Excellent condition, zero dead pixels, never noticed any of the issues that were listed on this topic. Had a big tax refund though and bought myself the Samsung LA46F81BDX to replace it as my Media Center monitor.

Anyone interested, PM me with your best offer. I'd prefer to sell it to someone on here, but if there's no takers, then it's onto eBay!

I'm in South-East Melbourne.

Cheers,

milka

I have the Acer AT3705-MGW TV and for the second time now it is being repaired. I have had it for around a year and a half and the picture is prety good but my dealings with acer haven't been as good. The 2 problems the TV has had from the start are as follows.

1. Some of the TV's channles wipe from it's memory and you have to reprogram it every now and then.

2. The TV will only display a black screen/ no picture but will have sound. It does this no matter what input is used, it just wont display a picture, and will do it most days but useally it starts to work properly by the end of the day, untill you turn it on the next morning and your back to a blank screen.

With issue 2. I sent it to High point repair center when it was about 6 months old, and when it got there they rang me and told me there was no problem with it and sent it back to me. Now a year later the problem is still there and I have sent it back again and this time I'm not letting them send it back to me untill they fix it, lucky it has a 3 year warranty.

I have also got consumer affairs involved to make sure it's fixed, replaced or refunded this time, its very annoying to bring home a hired DVD only to find you can't watch it.

Also want to add that it took acer 3 weeks both times it was returned for them to get a courier to pick the TV up. :angry2:

Just thought I add to the discussion. To anyone that this this TV (I have the North American version, model AT3705), and trying is trying to get 1080P via DVI with XBMC, I got it to work. It took much trial and error, but I finally got it.

The displayed resolution is 1920x1080P@30Hz. I was hoping to get 60Hz, but I get "out of range" with that setting. Looks like this is the best I'll be able to do. 24Hz, and 25Hz work as well. Unfortunately, there is occasional flicker during playback.

Note, the HTPC I'm using has the Zotac Ionitix A-U motherboard. I'll assume these settings will work with any ION based board. Here is my xorg.conf file.

I'm amazed how much sharper the DVI connection is over HDMI.

I'm amazed how much sharper the DVI connection is over HDMI.

I did some more playing around, and was able to establish 1080P via HDMI. DVI is still sharper, so I'll stick with it. Here's my updated xorg.conf file.

Hi all,

Have a problem with my Acer LCD 3705. I've not had the tv long, its actually second hand but this is the first time that ive had this problem. The problem is that i am constantly getting a blank screen. I turn it on and after a second the screen automatically turns itself off and the tv sets itself to standby.

Anyone have any ideas on what it could be? Its a good tv and i dont want to get rid.

Thx.
