Question about Dynex 19 in. LCD Flat-Panel HDTV

2 Answers

19'' Dynex TV does not come up as a Computer Monitor.

I read the manual. Cable connected. Pressed both "fn" and "f4" at the same time. Computer (Compaq Presario Laptop) screen blanked. OK. But the Dynex TV screen stayed blank. Tried all the buttons on the TV Remote. No go. Pressed fn + f4 ... laptop screen back ... again, off ... again, back ... etc. Tv screen stayed blank.

This TV works fine for my DVD player. Channel TV too, though I don't care to watch it.

    When you say video driver, what are you refering to? I am working through the PC connection - when I try to bump up the resolution to what the TV should be capable, the tv goes black and gives me a message about 'the signal not being supported'

    Same sa me but i have a 26" DYNEX LCD and mine says "NO SIGNAL"

  • Anonymous Apr 07, 2009

    I plug in to the Tv Via a VGA cable, then turn on my Presario, I get an error message saying VGA4 not supported.

    The solution is to reinstall the driver with TV connected (apparently), but no directions are given on how to do any of this.

    Please give step by step on how to solve the problem.

I had this same problem with the 19" model as well. I had to reinstall video driver with the tv hooked up in order for the resolutions to work properly. In order to do this I used an S-video cable which worked well enough to reinstall the video driver. I did not try safe mode which might have been easier, I just did not think of it at the time. With the video driver reinstalled while the TV is attached to my computer, I know enjoy a crisp 1440x900 screen resolution. Hope this helps.

My dynex 19" lcd tv doesn't work when i turn it on and try to set it up all i get is a distorted screen that you cant read i was told that it has to be reprogrammed is there software for a computer to fix...

When you turn it on press the set up/menu button. Make sure your cable is unplugged first. When in set up, go to channel setup and scan channels. Once the scan has started connect your cable back to the tv. Allow some time for the scan to complete. ***I learned this when I emailed a dynex technician. If it does not work after the above, email dynex

How can I use my lg 3d tv as netbook pc monitor using agp to hdmi cable

Connect your tv to your PC . Turn your pc on and let the os (operating system) boot up. Then find the function key (f1-f12) usually has a rectangle symbol with a line on either side. Example f4. Then hold the function key fn which is located bottom left of key board. And press f4 (if this is your video toggle) it will cycle through original monitor, both original and external monitor, and finally external monitor only. If done again it should reset to original status.

I just want to know what kind of cable I need to connect my LTV-37w2HD TV to my computer?

The video cable should be a VGA cable, assuming your computer has a VGA connector. Get one that has M/M ends. This is sometimes listed as a 15 pin D-sub connection. Then connect a 3.5 mm audio patch cord (m/m) between the audio out (speaker/headphone) pf the computer to the TV's VGA audio in (if you want to use the TV speakers).

If your computer has an HDMI or DVI output, I do not believe that you can connect to the TVs HDMI port. (The signal from the computer is not the same as that from a set top box.) If you have a DVI port, get a DVI to VGA adapter and then connect to the VGA cable. (You could use a DVI-DVI cable and then the DVI to VGA adapter at the TV. However, space is an issue at the TV.)

Make sure that the VGA port is enabled on the computer. (Some newer computers have a different video port enabled initially.) This may require entering your BIOS just after turning on the computer. Usually you need to strike Esc, F1 or F2 repeatedly starting when you press the power button. (F10 is also a BIOS access with some manufacturers - the key will be listed in a splash screen that is only visible for a few seconds.)

With the computer and the TV off, connect the cables. Then turn on the TV and set the input to VGA. Next turn on the computer. (If this is the only monitor attached, the computer should find the correct resolution (Windows). If you are using a dual monitor option, then you may have to enable the TV as a monitor. This will depend on the OS. For my Windows 7 laptop, it's right click on the desktop and choose Graphics Properties. Set the monitor options for both, external or attached and click Apply. Then click OK when a confirmation window appears. With my Windows 7 desktop, it's right click on the desktop and choose Screen Resolution. Similarly choose the settings, click Apply then OK to confirm.)

I hope this helps.

I need to connect my laptop to the LCD TV. Please tell me after connecting VGA with audio cable, what I should do on laptop to get the desktop details on TV Monitor? N.K.Makam

Hold the "fn" key and press the corresponding function key at the top to change the display. There should be a picture on the key that implies this function. For example, my compaq laptop uses the F4 key for this so i would press and hold "fn" then press and release F4.

I have my laptop plugged into my 32" Dynex TV and the only thing that is showing up on the TV is my desktop picture and the resolution preferences window when i open it. Is there a way that i can fix this?

sounds like your set up on extended screen where your laptop still show desktop and your tv shows only the desktop picture. if you have a fn button or like, should be next to the left ctrl button press it and on my laptop its f4 but maybe different on yours should scroll through the different output modes. failing that check your output modes on your laptop going to control panel/display properties and change your settings. hope this helps i can't tell you how to change them or what to change them to as i got a intel setup program for doing it.

How to use as monitor for laptop

i assume the TV has a VGA port (blue 15-pin) and that you're using a VGA cable.

the TV will usually have another A/V or input specifically for the VGA which can be called anything from "PC" to "other" make sure you've got that input selected

once you've got all that tell your PC to connect (button looks like a box with a line on each side) by pressing "fn" + "f4" if you have an HP...i think dell uses "fn" + "f8" i think Asus uses "fn" + "f5". (**usually if you press it once it will turn off your comp screen and transmit to tv, if you press a second time it will go back and if you press a third time it will tranmit to both at the same time)
if this is the first time you've connected your laptop to something it usually brings up a screen to configure some options like do you want to mirror the screen or use the tv as an extension of the screen.

hope this helps

I have a dynex TV I am trying to connect to my laptop via HDMI. The TV works fine as far as displaying cable but when I try to hook it up to my laptop the screen displays for one second then flashes to...

Make sure that you set your laptop to external display by using the proper F key, located on top of the keyboard. It looks as though there are two computer monitors on it. My Gateway is F4 for example. Press the function key and the proper F key simultaneously. There are a few choices, so you may have to push it more than once. I hope this helps and good luck!
