Title: 4:3 1080i HDTV CRT, great success!
Post by: kLAcK on July 06, 2009, 07:42:34 pm
I purchased a Samsung TX-R2779H figuring it would be a good fit for an arcade monitor.  It is a 4:3 CRT, but it support 720p and 1080i.  The picture is great and detailed, however it seems to be zoomed in a bit.  All edges are cut off.  I am using a DVI to HDMI cable to connect to it from my PC. 

I tried playing with the timing in powerstrip, to try and shrink the image, however I could not shrink it, only move the image up or down a hair.
There are no positioning or stretching options available on the TV menu.

Does anyone have any suggestions?  Do you think that connecting with DVI->Component will yield better results/options?

Found the service menu for the TV and fixed it through that  ;D ;D ;D

Can't wait to get this thing in my cab.  For anyone wondering if they would like to use this type of TV for their cab, so far so good for me.  Picked it up on craigslist for $150.

Its always hard to take pictures of a TV, but here you go.

This is a 27" CRT TV

This is a DVI->HDMI connection, so sharpness is great and there is no image degradation.

The desktop is readable at 1024x768, and 800x600 and 640x480 modes are perfect.

Street fighter looks best at 1280x720 with 4:3 aspect ratio correction (for some reason), all text reads well.

The only issue I have is when something big and bright goes across the screen, the image will stretch a little.  But this is no big deal to me.  For $150 you can't beat it.  Because of the DTV conversion, these sets are at rock bottom prices.

That's called blooming.  The Samsungs (and pretty much every other TV out there) have the contrast cranked to infinity by default.  Try turning that down and it should help a bit.  I actually have the 30" widescreen slimfit like that one.

1270x720 is a 16:9 resolution (there os no 4:3 HD resolutions), so is not strange you need to use 4:3 aspect ratio, elsewice it would look strected.

the wierd thing is that it renders the fonts clearer than a traditional 4:3 resolutuion. And sure there are 4:3 high definitions. 1280x1024 is a higher definition than 720p  ;D

Question?  What video wiring set up does your computer have for output and what did you use to connect it for a tv to read the signal.  I have tried to connect a tv to my computer in my 1995 virtual fighter 2 and all I get is garbly gook.  I have the color wires of RGB as outputs for my video to my old monitor.  I have tried hooking up a tv even by using the RGB connections with no good results.  How did you accomplish the connection problem?

This TV inputs HDMI, and my PC outputs DVI.  So I used a DVI to HDMI converter cable from monoprice.   Also Windows recognized the brand of monitor and supported resolutions automatically.
