This thread is for issues of interest to owners of the Toshiba DLP series.

For discussion of Configurations, Settings, Tweaks and Issues of all sorts.


My configuration: Toshiba 52HM84

HTPC (1.6GHZ P4) with MSI G4Ti4600 w/DVI out

going to a DVI to HDMI cable (from pchcables.com aprox $26)

and a MyHD HDTV tuner/recorder card with DVI daughter board


The DVI tuner output of the MyHD is awesome!!! I am getting some dropouts

which I am not too woried about as I have only tweaked with it for an evening.


I am interested in using my monitor with an HTPC. My thanks to member

remotepc who was the first to report that the 52HM84 works with the DVI

output of nvidia cards (and probably types as well).


I am using the MyHD HDtuner/recorder/DVD player card in my computer.

I have the version with the DVI daughter board. My DVI video card output

goes into the MYHD and the MyHD DVI output goes to the Toshiba. I see

my desktop with a window containing HD content or when I switch to HD

mode I see the tuner or DVD output from the MyHD full screen. The picture

quality on HD OTA reception is simply STUNNING. The quality on DVD playback

left me with tears of JOY. I am a very very very happy 52hm84 owner!!!!


I can see my desktop on the DLP but there is significant over-scan and the

mapping of pixels to mirrors dose not seem to be the ideal 1-1. I have played

with powerstrip a little and have been able to move the image a bit so I can

at least see part of the task-bar. I am interested in hearing from anyone who

has made advances in fine tuning the DVI timing parameters as well as any

other HTPC configuration info.

2 requests for current owners (as I'm still awaiting my HMX):


1) Does anyone know how to get to the Service Menu on the Toshiba HM series? I assume the code is the same for the HMXs...


2) Please post your pictures, too! Let's see some of those setups in action.

I'm going to look at the 52" HX later in the week, once my local dealer gets his shipment. If everything looks good and it passes the rainbow exam I may be bringing one home since I have a connection there (owners are the best ones) and should get a great deal.


So I'm very interested in following this thread.....and may become an active participant soon.

I initially bought a Samsung HLP5063 at Best Buy and then found out about the powerbuy. I returned the 5063 and bought the Samsung HLP5663 through the powerbuy. It was defective out of the box. I asked them to replace it with a Toshiba 52HM84 and it just arrived yesterday. I really sweated whether to stick with the Samsung or switch to the Toshiba and so far I am please with my decision to go with the Toshiba. I've only had the Toshiba a day but here are some observations comparing the two TVs:


- The Toshiba looks nicer sitting in my family room. It looks less like a big box and more sleek.

- The Toshiba starts much faster then the Samsung.

- The Samsung has more connections. Fortunately I don't need more connections but in the future I may need to buy a switch.

- The Toshiba seems quieter than the Samsung. Fan noise is almost inaudible.

- Out of the box HD picture quality is better on the Toshiba. Colors seem more natural. Picture is very detailed, clear and seems to look more 3-D.

- Out of the box SD picture quality is better on the Samsung. I have not had time to tweek the Toshiba but it shows every flaw in a SD signal. The "softer" picture of the Samsung is much more forgiving.

- X-Box looks great. I only played it for 30 minutes but so far no lag.


I'm sure I'll have more observations in a few days.

GSOgymrat; where was the brightness set at OTB and did you have to reduce it because of gray blacks?

What was wrong with the 2nd Sammy? How did the exchange go? Did they pay for return shipping and the Toshiba shipping? Did you have to contact the trucking company or did they?

I purchased a 52HM84, it should arrive at my sports bar tomorrow (Wed). It will be our first HD TV, to go along with our 16 SDs. I am hoping that the SD sports are not too bad, but can't wait until the HD football games start. Which actually is this Sat. USC vs Virginia Tech on ESPNHD.

I'll tell more when we get it set up.

Videobruce--

I have not had a chance to calibrate it yet-- everyone is watching the Olympics. The second Sammy had this bizarre problem where everything that should be black was bright red (see picture below). I let it run a few days the picture continued to degrade and then it finally would not turn on. TVA said they were going to have the old one picked up when they delivered the Toshiba. Overnite said they did not have instructions to pick up the old set and even called back to heaquarters to be sure. The Samsung is in it's box in my garage. I didn't pay for shipping on the Toshiba and I have no intention of paying for the Samsung to be returned.

I'd be happy to buy the Sammy off you for $100 plus shipping

I have had my 52HM84 for a week now. I am extremely happy with the quality of this Set. I have a HD Tivo connected to it, using component video(My HDMI Port on the HD TIVO is dead), and the quality is awesome. I wish there were more connections to the TV. I really wish the HD Tivo had more output connections.


I did set the bulb to low power mode, and have lowered the brightness during late night viewing.


I have a quick question though. How do you enable the output audo ports on the 52HM84?

I am running the HD Tivo video out through the component video, and audio out to the Set, and due to the HD Tivo only having 1 set of audio output jacks, I cannot seem to send the Audio to my DVD-Recorder(The DVD recorder video is connected to the HD Tivo S-Video output).


What I tried is using the Audio output jacks on the 52HM84, and connect it to the DVD recorder. But I get no Audio.


Anyone know what I am doing wrong?



Thanks,

Vizcaya

for simple audio connections you can piggyback. Go to your local radio shack

(or whatever) and get somthing like this:

to make two audio outputs out of one (on the hd-tivo)

Just got my 52hM84 yesterday afternoon, and only had time to watch some DVDs. Comcast will come in tomorrow to setup the HD box. So far, the DVD quality is great through component outputs. I just have a couple questions. The 6ft component cable I have is over 3 years old, and pretty thin. Would I be able to get better quality picture with a thicker component cable or a shorter one?


If I upgrade to a DVI dvd player, would that also result in better PQ?


thanks

Unless the old cable is of really poor quality it will not make a visable

difference. Any reasonable quality shielded cable should work well. I

dont agree with those who have almost religious zeal for super expensive

"monster cable". It's a shielded piece of wire with fairly low bandwidth

requirements.


>>If I upgrade to a DVI dvd player, would that also result in better PQ?


A highly critical viewer on a really good DVD transfer would say YES.

If the DVD player dosent have an HDMI output you will

have to get a DVI to HDMI adapter and run seperate audio cables.


I prefer to use an HTPC for all my signal needs....but not everyone

wants to add the extra complexity.

That much overscan?! I am ready to pull the trigger, but this much overscan is worse than my CRT. One of my major requirements and reasons for the upgrade is to eliminate the overscan issue and use this as a HTPC monitor. Any luck cleaning this up a bit? Btw, I have a ATI x800 Pro card, any luck on these cards? Thanks much.

Somebody was looking for this measurement recently. The base on the 52HM84 is smaller than the upper part of the TV.


The base measures 42 1/8" by 14 7/8". The overall width of the TV with speakers is 58", and the overall depth is 15 1/8", which is a couple of inches less than the Samsungs.

Thank goodness it works!


Still, it seems a bit grainy/hyper-sharp. Does that make sense?

Then again, it's just a digital/non-HD Dish Network connection via coaxial cable. (I'm not sure of the model number of the satellite box). There's an s-video outlet on the back of it, but I couldn't get it to work properly. When I unplugged the coaxial cable from the TV, it didn't work. Am I doing something wrong?


Progressive scan Gamecube, connected via component, looks wonderful. I'll be playing all of my games again, just to enjoy the beauty. (hehe.. I almost got a bit dizzy while playing F-Zero.. lol..)


Has anyone calibrated theirs yet? Any good settings? Does AVIA make that big a difference? I'm guessing my way through the video settings menu, but to no great success. If I could get my Dish Network feed to look half as crisp as the "Volume" meter, I'd be so pleased..

Use as a monitor is a priority for me too...but since I have had it for only

three days and my wife loves watching the Olympics... not much time for

tweaking yet...Be advised that along with my manual came an extra sheet

saying that the monitor is not intended for use as a PC monitor...This

was a little disapointing....but I am still confident that with some tweaking

it can be made to work (much like the case with the Samsung DLP's) By

reading other threads about other people finding the right combination of

timing information to make it happen for various other displays

I feel it's just a matter of time. stay tuned.

Hello all..


I've had my 52HM84 since Saturday and I'm enjoying it.


Now, I want to take a big step and do what the owners manual says not to do (for what reason, can anyone tell me?): Hook up HTPC


Basically, my PC will have an HDTV Wonder and Radeon 9600XT. I have purchased a DVI/HDMI cable. I'm not going to blow up the Toshi by plugging the radeon into it am I?


I have heard some problems about compatibility between a PC output and a TV/monitor input having to do with scaling problems, sync problems, etc. I am anticipating that I will need to tweak the outgoing video signal if this is going to work at all.


So can anyone give me any advice?


Much appreciated!

NO, but the Toshiba Police will hunt you down and force you to watch I Love Lucy reruns..........

I hooked my htpc on the first day. On my (nvidia) card the DVI output

was not active if the analog VGA was connected but this depends on the

mode the drivers expect you to use the DVI port (clone or dual monitor).

I found that at boot the Toshiba will sink to the 640x480 initial resolution

but the overscan will be significant. My first step was to boot on a standard

analog vga monitor and set it for 1280x720, power down pull out the vga

and plug in the DVI and reboot. I expect you will at least see desktop. You

will have trouble seeing the task bar (because of overscan) and the problem

with powerstrip is that once it's installed it is activated from the system tray.

You will have to avtivate it w/o seeing the cursor. The latest version of

powerstrip has a lot of preset resolutions for DLP and LCOS monitors. I

would try these first. Powerstrip also allows you to tweak the actual

timing parameters interavtively. Some of these will cause you to loose

picture. learn the powerstrip hot-key that restores the default frequencies.

By playing with the front porch/back-porch setting I was able to get most

of the taskbar displayed. Powerstrip will remember this and the next time

you boot you will start from there.


This is all I have learned from a single short session. I encourage you to go

ahead and experiment. The more of us working the sooner the solution. I will

(and encourage you) to search these forms for information on how others

have achieved 1-1 pixel mapping. You will know you are there when you

see razor sharp non-grainy characters. The (non 1to1) effect looks exactly the

same as setting your laptop resolution to a resolution different from it's

native resolution. Please share your results.
